A Full-Mouth Reconstruction To Replace Decayed and Broken Teeth

A radiant smile is not only a symbol of beauty but also a reflection of one’s self-confidence and overall well-being. Full-mouth reconstructions, a highly specialized treatment within prosthodontics, have gained recognition for their ability to restore and or replace both the aesthetics and function of a person’s teeth . 

Full-mouth reconstructions go beyond cosmetic enhancement. They are designed to give individuals a renewed sense of self-assurance and the ability to enjoy life fully. This transformational journey begins with a detailed assessment and meticulous planning, as every case is unique, presenting its challenges and opportunities.

In this article, we’ll walk you through the journey of a patient who, like many others, was confronted with the harsh reality of decayed and broken teeth, see pictures below. The impact of her dental condition went beyond mere physical discomfort. It extended to her self-esteem, her social interactions, and even her dietary choices.

This case, although challenging, serves as a testament to the power of modern prosthodontics to restore not only the aesthetics of one’s smile but also the functionality that is crucial for a better quality-of-life. Because all of the teeth were non-restorable, the plan was to replace the teeth with dental implant bridges (also called All-on-4).

Initial Assessment and Planning

When embarking on a full-mouth reconstruction, meticulous planning is the cornerstone of a successful transformation. The significance of this phase cannot be overstated, as it lays the groundwork for the entire journey.

Making Impressions:

  • Impressions are the first essential step in designing the new set of teeth. They serve as the building blocks in which the entire procedure is constructed.
  • Impressions are now made digitally to capture the unique characteristics of the patient’s oral structures. A digital 3D model is created to begin planning the reconstruction.

Evaluation of the Face and Smile Line:

  • Careful evaluation of the patient’s face and smile line is imperative. This evaluation goes beyond the confines of the oral cavity and extends to the patient’s entire facial structure.
  • Each individual’s smile line is unique, and the new teeth must harmonize with the smile to achieve both aesthetic and functional success.

This initial phase ensures that the treatment plan is tailor-made to suit the patient’s specific needs. It is here that the foundation is laid for a smile that not only looks beautiful but also functions optimally, bringing a renewed sense of confidence and comfort to the patient’s life.

Bone Assessment and Implant Placement

Assessing the underlying bone structure and the strategic placement of dental implants play pivotal roles. This phase is crucial for ensuring long-term success and functionality.

Role of Bone Assessment:

  • Before any treatment can proceed, a thorough assessment of the jawbone is essential. The height and width of the bone help to determine the proper position of the dental implants.
  • This assessment guides the treatment planning, helping prosthodontists make informed decisions about how the teeth will be replaced.

Utilizing X-rays and CT Scans:

  • To conduct a comprehensive evaluation of the jawbone, CT scans are utilized. These 3-dimensional images allow for precise measurements of the bone and to visualize vital structures. 
  • CT scans enable the prosthodontist to visualize the volume of bone and make informed decisions about the position of the dental implants. The image below shows the locations of where implants will be placed in the upper jaw. 
Bone Assessment and Implant Placement

Dental Implant Placement:

  • Dental implant placement is a critical step in the restoration process. It is important to create a solid foundation for the final restorations. 
  • Implants serve as the foundation for the prosthetic teeth. They are carefully positioned using a surgical guide based on the information shown above. The goal is to maximize the spacing of the implants so that the biting forces on the implant bridges can be well distributed. 

The careful combination of bone assessment, imaging technology, and precise dental implant placement ensures that the smile makeover not only appears visually stunning but also functions seamlessly, allowing the patient to enjoy a more fulfilling life.

Prosthetic Restoration

Immediately following the placement of dental implants, the treatment enters the phase of prosthetic restoration. This phase is where the patient’s vision of a complete, beautiful, and functional smile takes shape.

Crucial Post-Implant Placement Phase

  • The post-implant placement phase is a pivotal step in the reconstruction process. After dental implant surgery, a period of healing and osseointegration is crucial.
  • Osseointegration refers to the process where the bone fuses with the implant, ensuring its stability and long-term success.
  • Immediately after implant placement, temporary implant bridges are adjusted and inserted into the implants to provide immediate function and aesthetics. These temporary, full-arch bridges actually help to secure the implants during the healing phase. 

The Healing Phase is Crucial 

  • The healing period, typically lasting around three months, allows the dental implants to fully integrate with the jawbone.
  • This phase is fundamental to the overall success of the prosthetic restoration, as it provides the necessary stability for the final prosthetic implant bridges. 

Crafting the Final Upper and Lower Implant Bridges

Once the healing period is complete, the prosthodontist proceeds to design and fabricate the final implant bridges. See final pictures below. 

  • For the upper teeth, a carefully designed zirconia implant bridge was milled to fit precisely into the 6 implants. Artistic characterization like surface texture, shade and shape are added to create a lifelike appearance. 
  • In the lower jaw, a similar permanent implant bridge was carefully crafted to fit seamlessly onto the four dental implants. This bridge is designed to occlude precisely into the upper bridge to restore functionality. 

This final prosthetic phase brings the full-mouth reconstruction full circle, giving life to the patient’s vision of a new, beautiful smile that not only looks natural but functions optimally. It’s the culmination of a comprehensive process that has the power to renew self-confidence, comfort, and overall quality-of-life.

Are Dentures Comfortable? A Prosthodontist’s Guide for Seniors & Implant Patients in Los Angeles and Orange County

If you’re missing teeth and considering dentures, one of the most common questions seniors and implant candidates ask is: “Will dentures actually feel comfortable?” The good news is—yes, modern dentures can be very comfortable when they are custom-made, properly fitted, and supported by today’s advanced dental technology. For patients in Los Angeles and Orange County, especially seniors looking to restore their smile, chewing ability, and confidence, today’s denture and implant options offer far more comfort and stability than ever before. In this guide, you’ll learn: Types of Dentures Available in Los Angeles and Orange County Choosing the right type of denture plays a major role in comfort, function, and confidence. Below are the most common options recommended for seniors and patients that are missing teeth.  1. Complete Dentures Complete dentures replace all teeth in the upper or lower jaw. These removable appliances rest on the gums and rely on suction and fit for stability. Best for: Patients missing all teeth who want a less expensive, removable option.Comfort level: Good with proper fit, but may feel less stable over time due to natural bone loss. Material: Acrylic                                                                                                                    Adhesive use: Sometimes required 2. Removable Partial Dentures Partial dentures replace several missing teeth and attach to the remaining natural teeth using clasps. Best for: Patients who still have some healthy natural teeth.Comfort level: Good when properly designed, though clasps may take time to get used to. Material: Metal framework with acrylic. 3. Implant-Retained Dentures These dentures look similar to traditional removable dentures but are less bulky and snap onto dental implants for stability. Best for: Patients who struggle with loose dentures.Comfort level: Excellent – dramatically more stable than traditional dentures.                    Material: Metal framework is hidden for strength and wrapped with acrylic.                                                            Adhesive use: Not needed As few as two implants in the lower jaw and four in the upper jaw can significantly improve comfort and chewing efficiency. 4. Implant-Supported Dentures (All-on-4 / All-on-X) This is the most advanced tooth replacement solution available. A full arch of fixed teeth is supported by four or more implants and does not come out. Best for: Patients who want permanent, natural-feeling teeth.Comfort level: Highest – closest feel to natural teeth.Material: Zirconia ceramic for strength and esthetics. For many implant candidates, this option delivers the most life-changing results. What Makes Dentures Comfortable? Several key factors determine whether dentures feel comfortable or problematic. 1. Proper Fit Complete denture comfort begins with precise custom impressions and detailed shaping of the denture borders to match the movement of your lips, cheeks, and tongue. This technique is called border molding and helps prevent soreness, rubbing, and looseness. For partial dentures, proper planning and preparation of the supporting teeth ensures thinner appliances and more comfort for the tongue, cheeks and surrounding tissues. 2. Correct Bite Alignment (Occlusion) Occlusion refers to how your upper and lower teeth come together when you bite. If the bite is uneven, dentures can rock, rub the gums, and cause sore spots. A balanced bite greatly increases comfort and chewing ability. 3. Dental Implant Support For many patients, implants are the key to truly comfortable dentures. Implants: Lower dentures benefit the most from implant stabilization. The Adjustment Period: What Patients Should Expect When transitioning from natural teeth to dentures, an adjustment phase is completely normal and usually lasts a few weeks to a couple of months. During this time, you may experience: Tips for a Smoother Transition After extractions, your gums and bone continue healing for several months. Once fully healed, a final hard reline is performed to improve long-term comfort and fit. Denture Care & Maintenance for Long-Term Comfort Daily care is essential for both comfort and oral health.  1. Rinse after meals to remove food particles.2. Brush daily using a soft denture brush with mild soap (no toothpaste).3. Clean your gums and tongue with a damp cloth.4. Soak dentures overnight in water or a denture cleanser. 5. Never use hot water, bleach, or abrasive cleaners. 6. Visit your dentist yearly for fit checks and relines. Over time, jawbone changes can loosen dentures. Regular professional care prevents discomfort and instability.

Zirconia Implants vs. Titanium: Health Benefits and Differences Explained

Dental implants have been a major advancement in replacing missing teeth. When placed correctly, titanium implants have incredibly high success rates and are the standard for tooth replacement. Dental implants can be used to replace a single tooth or can be strategically placed to support multiple missing teeth or a whole arch of teeth. The great benefit of dental implants is that they eliminate a removable denture and provide the function and appearance of natural teeth.  Over the past couple years, patients have become concerned about the idea of having metal titanium implants placed in their body. Some patients are not comfortable with the idea of having a “foreign metal object” placed into their jawbone. I can understand their concern especially if they are unsure of the science, materials used and potential risks. So much information is available on the internet and it is difficult to find answers to these questions. Because of this, some patients are more comfortable with the idea of non-metal zirconia implants as an alternative. So, are zirconia dental implants healthier than titanium dental implants?  Composition of titanium dental implants Titanium (Ti) is a metallic element with the atomic number 22 and has a silvery color. It is the ninth most abundant element in the earth’s crust. The alloy Ti-6Al-4V (Titanium, 6-aluminum, 4-vanadium), which was originally used for aerospace applications, is currently the most frequently used material for medical and dental implantation. Titanium alloys are widely used for orthopedic implantation (joint replacements) because of their lightweight, high biocompatibility and favorable strength/density ratios. Titanium alloys are superior to stainless steel and cobalt-chrome (Co-Cr) alloys with regard to biocompatibility and corrosion resistance.  Titanium plays a pivotal role for dental implants because the roughened surface of these implants attract bone cells to deposit bone and fill the space between the jawbone and the implant surface. This process is called osseointegration and is critical for implant stability. Titanium dental implants quickly form a layer of titanium dioxide on the surface and this layer forms a boundary between the metal surface and the body, preventing corrosion and deterioration of the material. This is the reason for the high biocompatibility.  Can titanium dental implants cause an allergic reaction?  Exposure to titanium from implants is common, but reports on clinical allergy are rare. Titanium dioxide on the surface of dental implants is more stable than pure titanium. It is possible that titanium ions could be released from the surface and sometimes into distant tissue. However, evidence for the possible toxic effects and risk of allergic reactions is weak (1). One study showed that titanium allergy can be detected in dental implant patients, even though its estimated prevalence is very low (0.6%) (2). It should be noted that no material, including any dental implant, can be considered universally biocompatible. As mentioned above, the Ti-6Al-4V alloy is the preferred choice for dental implants. Small amounts of other elements associated with titanium alloys can act as “impurities.” Titanium alloys can contain very small amounts of beryllium, cobalt, chromium, copper, iron, nickel and palladium. These impurities may be causative factors for different allergic reactions in patients with dental implants, but the likelihood is low.  It is therefore advisable to test for titanium allergy in patients with a history of multiple and/or severe allergies. These include allergy to jewelry, nickel and cobalt. Furthermore, patients with previous unexplained implant failure could be tested. In the rare situation that a patient is allergic to titanium, it is preferable to use alternative treatment options or to use an alternative dental implant material such as zirconia (3).  What are zirconia implants?  The idea of an alternative to titanium dental implants has been growing for years due to the questions regarding sensitivity to titanium that was discussed above. Another drawback of titanium is its grey color. When a titanium implant is placed in an area with very thin gingival tissue, there is a risk that a dark grey shadow may be visible.  Zirconium dioxide (zirconia) has been introduced as an alternative to titanium dioxide. Zirconia was first used for the fabrication of dental crowns and implant abutments. Currently, tetragonal zirconia poly-crystal is the ceramic of choice for dental implants. The white, opaque color of zirconia along with the good biocompatibility, favorable mechanical properties and low affinity for bacterial plaque, make it a good potential material for dental implants.  Are zirconia implants as successful as titanium implants?  Osseointegration is a major factor in the success of modern dental implants. Titanium remains the material of choice for obtaining and maintaining osseointegration. Early studies show that zirconia implants have similar 1 and 2 year survival rates when compared to titanium implants. More clinical long-term studies providing detailed information about implant failures, biological and technical complications, and prosthetic and esthetic outcomes are urgently needed (3). Potential implant abutment and crown complications Once a dental implant has integrated and healed with the jawbone, an implant abutment and crown are then made to complete the replacement of the tooth. The abutment and crown is held into the implant by a screw. These 3 components are shown in the picture below.   When titanium is used for the implant and abutment, this connection is incredibly strong and stable with very few mechanical complications from chewing. On the other hand, zirconia is a more brittle material compared to titanium. When zirconia is used for the implant and abutment, more mechanical complications (breakage of the abutment) have been reported, see picture below. This has been reported in studies and I have also experienced this in my practice. The challenge with zirconia is the strength and stability of the connection between the abutment and implant. So far, this connection is not as reliable as titanium. When implant abutments break, this expensive abutment and crown needs to be replaced and has the possibility of breaking again.   Conclusions References At Geach Dental in Downtown Los Angeles and Laguna Niguel, Orange County our team has extensive experience in dealing with dental implant issues.

Correct Bite Alignment (Occlusion) Occlusion refers to how your upper and lower teeth come together when you bite. If the bite is uneven, dentures can rock, rub the gums, and cause sore spots. A balanced bite greatly increases comfort and chewing ability. 3. Dental Implant Support For many patients, implants are the key to truly comfortable dentures. Implants: Lower dentures benefit the most from implant stabilization. The Adjustment Period: What Patients Should Expect When transitioning from natural teeth to dentures, an adjustment phase is completely normal and usually lasts a few weeks to a couple of months. During this time, you may experience: Tips for a Smoother Transition After extractions, your gums and bone continue healing for several months. Once fully healed, a final hard reline is performed to improve long-term comfort and fit. Denture Care & Maintenance for Long-Term Comfort Daily care is essential for both comfort and oral health.  1. Rinse after meals to remove food particles.2. Brush daily using a soft denture brush with mild soap (no toothpaste).3. Clean your gums and tongue with a damp cloth.4. Soak dentures overnight in water or a denture cleanser. 5. Never use hot water, bleach, or abrasive cleaners. 6. Visit your dentist yearly for fit checks and relines. Over time, jawbone changes can loosen dentures. Regular professional care prevents discomfort and instability.

Zirconia Implants vs. Titanium: Health Benefits and Differences Explained

Dental implants have been a major advancement in replacing missing teeth. When placed correctly, titanium implants have incredibly high success rates and are the standard for tooth replacement. Dental implants can be used to replace a single tooth or can be strategically placed to support multiple missing teeth or a whole arch of teeth. The great benefit of dental implants is that they eliminate a removable denture and provide the function and appearance of natural teeth.  Over the past couple years, patients have become concerned about the idea of having metal titanium implants placed in their body. Some patients are not comfortable with the idea of having a “foreign metal object” placed into their jawbone. I can understand their concern especially if they are unsure of the science, materials used and potential risks. So much information is available on the internet and it is difficult to find answers to these questions. Because of this, some patients are more comfortable with the idea of non-metal zirconia implants as an alternative. So, are zirconia dental implants healthier than titanium dental implants?  Composition of titanium dental implants Titanium (Ti) is a metallic element with the atomic number 22 and has a silvery color. It is the ninth most abundant element in the earth’s crust. The alloy Ti-6Al-4V (Titanium, 6-aluminum, 4-vanadium), which was originally used for aerospace applications, is currently the most frequently used material for medical and dental implantation. Titanium alloys are widely used for orthopedic implantation (joint replacements) because of their lightweight, high biocompatibility and favorable strength/density ratios. Titanium alloys are superior to stainless steel and cobalt-chrome (Co-Cr) alloys with regard to biocompatibility and corrosion resistance.  Titanium plays a pivotal role for dental implants because the roughened surface of these implants attract bone cells to deposit bone and fill the space between the jawbone and the implant surface. This process is called osseointegration and is critical for implant stability. Titanium dental implants quickly form a layer of titanium dioxide on the surface and this layer forms a boundary between the metal surface and the body, preventing corrosion and deterioration of the material. This is the reason for the high biocompatibility.  Can titanium dental implants cause an allergic reaction?  Exposure to titanium from implants is common, but reports on clinical allergy are rare. Titanium dioxide on the surface of dental implants is more stable than pure titanium. It is possible that titanium ions could be released from the surface and sometimes into distant tissue. However, evidence for the possible toxic effects and risk of allergic reactions is weak (1). One study showed that titanium allergy can be detected in dental implant patients, even though its estimated prevalence is very low (0.6%) (2). It should be noted that no material, including any dental implant, can be considered universally biocompatible. As mentioned above, the Ti-6Al-4V alloy is the preferred choice for dental implants. Small amounts of other elements associated with titanium alloys can act as “impurities.” Titanium alloys can contain very small amounts of beryllium, cobalt, chromium, copper, iron, nickel and palladium. These impurities may be causative factors for different allergic reactions in patients with dental implants, but the likelihood is low.  It is therefore advisable to test for titanium allergy in patients with a history of multiple and/or severe allergies. These include allergy to jewelry, nickel and cobalt. Furthermore, patients with previous unexplained implant failure could be tested. In the rare situation that a patient is allergic to titanium, it is preferable to use alternative treatment options or to use an alternative dental implant material such as zirconia (3).  What are zirconia implants?  The idea of an alternative to titanium dental implants has been growing for years due to the questions regarding sensitivity to titanium that was discussed above. Another drawback of titanium is its grey color. When a titanium implant is placed in an area with very thin gingival tissue, there is a risk that a dark grey shadow may be visible.  Zirconium dioxide (zirconia) has been introduced as an alternative to titanium dioxide. Zirconia was first used for the fabrication of dental crowns and implant abutments. Currently, tetragonal zirconia poly-crystal is the ceramic of choice for dental implants. The white, opaque color of zirconia along with the good biocompatibility, favorable mechanical properties and low affinity for bacterial plaque, make it a good potential material for dental implants.  Are zirconia implants as successful as titanium implants?  Osseointegration is a major factor in the success of modern dental implants. Titanium remains the material of choice for obtaining and maintaining osseointegration. Early studies show that zirconia implants have similar 1 and 2 year survival rates when compared to titanium implants. More clinical long-term studies providing detailed information about implant failures, biological and technical complications, and prosthetic and esthetic outcomes are urgently needed (3). Potential implant abutment and crown complications Once a dental implant has integrated and healed with the jawbone, an implant abutment and crown are then made to complete the replacement of the tooth. The abutment and crown is held into the implant by a screw. These 3 components are shown in the picture below.   When titanium is used for the implant and abutment, this connection is incredibly strong and stable with very few mechanical complications from chewing. On the other hand, zirconia is a more brittle material compared to titanium. When zirconia is used for the implant and abutment, more mechanical complications (breakage of the abutment) have been reported, see picture below. This has been reported in studies and I have also experienced this in my practice. The challenge with zirconia is the strength and stability of the connection between the abutment and implant. So far, this connection is not as reliable as titanium. When implant abutments break, this expensive abutment and crown needs to be replaced and has the possibility of breaking again.   Conclusions References At Geach Dental in Downtown Los Angeles and Laguna Niguel, Orange County our team has extensive experience in dealing with dental implant issues.
