Full-Arch Dental Implant Rehabilitation Case Report

Restoring Function, Comfort, and Confidence with Implant Dentistry in Los Angeles & Orange County

When patients lose multiple teeth or experience severe dental breakdown, everyday activities like chewing, speaking, and smiling can become difficult and frustrating. In this complex implant reconstruction case, Adam Geach, DMD, MDSc — Prosthodontist at Geach Dental — restored a patient’s bite, function, and appearance using advanced dental implant treatment and full-mouth reconstruction techniques.

This type of case highlights why specialized prosthodontic training matters when rebuilding a patient’s occlusion with dental implants.

The Patient’s Concerns

The patient came to Geach Dental with several serious dental problems, including:

  • Multiple missing teeth
  • Loose and failing lower teeth
  • Advanced periodontal bone loss
  • Difficulty chewing comfortably
  • Shifting teeth and collapsing bite
  • An aging, worn appearance caused by tooth loss and bite collapse

These issues not only affected appearance but also severely impacted daily function and long-term oral health.

For many patients in Los Angeles and Orange County, this situation is more common than they realize. Missing back teeth and failing dental work can gradually cause the bite to collapse over time, leading to difficulty eating, jaw strain, and accelerated tooth wear. See pictures below. 

Diagnosis: Advanced Bite Collapse and Tooth Loss

After a comprehensive prosthodontic evaluation, the diagnosis included:

  • Missing posterior (back) teeth
  • Severe periodontal disease in the lower jaw
  • Significant bone loss around lower teeth
  • Tooth shifting and migration
  • An overclosed bite
  • Reduced chewing efficiency and function

Because the remaining lower teeth could not be predictably saved, a full-arch implant reconstruction was recommended.

Advanced Digital Treatment Planning

Complex implant cases require careful planning before any treatment begins. At Geach Dental, advanced digital scanning and prosthodontic treatment planning were used to determine the ideal tooth position, bite relationship, smile design, and implant placement.

One of the most important goals in implant dentistry is not simply replacing teeth — it is restoring the bite in a healthy, stable, and natural way.

Most of the patient’s upper teeth were healthy enough to preserve, while the remaining lower teeth required extraction due to extensive bone loss.

Full-Arch Dental Implant Reconstruction

After removing the failing lower teeth, precision-guided implant surgery was performed.

Treatment Included:

  • 2 upper dental implants to replace missing upper molars
  • 5 lower dental implants to support a full-arch fixed implant bridge
  • Digitally guided implant placement for precision and long-term stability

Following a healing period of approximately three months, the implants were restored with:

  • Individual implant crowns in the upper jaw
  • A custom full-arch fixed bridge in the lower jaw

Unlike removable dentures, this implant bridge is permanently fixed in place, giving the patient a much more natural and secure experience while eating and speaking.

A Smile Designed for Function and Long-Term Health

At Geach Dental, implant restorations are designed not only for esthetics, but also for long-term maintainability and hygiene.

The lower implant bridge was carefully designed to allow the patient to floss effectively and clean around the implants using specialized hygiene tools such as a water flosser.

This is a critical aspect of successful implant dentistry that is often overlooked.

The Final Result

The completed reconstruction restored:

  • Proper bite function
  • Improved chewing efficiency
  • Smile esthetics
  • Facial support
  • Long-term stability and comfort

The patient can now comfortably eat a wide range of foods without worrying about loose dentures or unstable teeth.

An additional benefit of this case was the ability to preserve the patient’s healthy upper front teeth. Minor cosmetic recontouring was performed to improve the appearance while maintaining natural tooth structure. See pictures below of the final result. 

Why Choose a Prosthodontist for Dental Implants?

A prosthodontist is a dental specialist with advanced training in:

  • Dental implants
  • Full-mouth reconstruction
  • Complex bite rehabilitation
  • Cosmetic dentistry
  • Smile design
  • Restoring damaged or failing dentition

Cases involving severe tooth loss, collapsing bites, or advanced implant reconstruction require far more than simply placing implants. Proper bite design, esthetics, jaw function, and long-term durability all need to work together.

At Geach Dental, patients receive highly customized implant and reconstructive treatment designed specifically for long-term health, function, and esthetics. If you have missing teeth and are looking to improve your chewing function and esthetics, we encourage you to contact Geach Dental at (213) 622-3339, or schedule a consultation. You deserve the best care.

When Old Veneers Make Your Smile Look Older

A Prosthodontic Approach to Replacing Aging Cosmetic Dentistry with Natural-Looking Restorations If you had veneers or crowns placed 10, 15, or even 20 years ago, you may have loved your smile when they were first completed. But smiles change—and so does cosmetic dentistry. Older veneers can look bulky, square, opaque, worn, or simply outdated compared with today’s more natural-looking ceramic restorations. Sometimes patients don’t want an entirely new smile. They just want their smile to look natural again. That was the goal for this patient. The Problem: Old Veneers That No Longer Looked Natural This patient was referred to Geach Dental because she was unhappy with the appearance of her four upper front teeth. Her existing veneers had several characteristics that made them stand out from her surrounding natural teeth. The front teeth appeared very square, all four restorations slanted slightly to one side, and the porcelain was relatively opaque rather than having the subtle translucency of natural enamel. See picture below.  The veneers weren’t simply “old.” They looked like dental work. Our goal was to change that. We wanted to replace the aging restorations with teeth that blended naturally into her smile—without creating an artificial or overly perfect appearance. Good Cosmetic Dentistry Shouldn’t Look Like Dental Work One of the misconceptions about cosmetic dentistry is that improving a smile simply means making teeth whiter. For us, natural-looking cosmetic dentistry is much more about the details. The shape, proportions, contours, translucency, alignment, and color of the teeth all need to work together. For this patient, our goals were to: Ultimately, people should notice your smile—not your dental work. Designing the New Smile Before Making the Final Teeth Before fabricating the final restorations, we created a digital diagnostic design for the four front teeth. This allowed us to establish the new tooth shapes and proportions before completing the final crowns. After removing the existing veneers, the teeth were conservatively prepared and custom temporary crowns were made from our new digital design. This is an important part of our approach to complex cosmetic dentistry. Rather than simply removing the old restorations and hoping the patient likes the final result, the temporary crowns allow us to test-drive the new smile first. The Patient Gets a Say in the Final Smile With the temporary restorations in place, the patient can see the proposed changes directly in her own mouth. We can evaluate: Most importantly, the patient can give us feedback. If we want a tooth slightly shorter, longer, softer, or more rounded, those changes can be made before the final restorations are fabricated. Once the temporary restorations look and feel right, they become the blueprint for the final teeth. That patient feedback and refinement process was an important part of this case. Why Replacing Only Four Front Teeth Can Be So Challenging You might assume that replacing four veneers is easier than restoring an entire smile. Esthetically, the opposite can sometimes be true. When we replace only a few front teeth, the new restorations must blend with the patient’s remaining natural teeth. The shade can’t simply be “white.” Natural teeth have subtle variations in color, translucency, texture, and brightness. Reproducing those characteristics is what helps a ceramic restoration look like a tooth rather than a crown. The goal is not to make four beautiful crowns. The goal is to make it difficult to tell which four teeth are crowns. The Advantage of Our In-Office Dental Laboratory At Geach Dental, we work closely with our in-office laboratory technician when creating highly esthetic restorations. This allows us to carefully control details such as: In this case, the final restorations were designed, milled, characterized, and finished in close collaboration with our technician, using the refined temporary crowns as the guide for the final result. For front teeth, these small details can make an enormous difference. The Result: A More Natural-Looking Smile The objective wasn’t to give this patient a completely different smile. It was to make her existing smile look more natural, balanced, and current. The new front teeth have softer contours, improved alignment, and a more natural relationship with the surrounding teeth. The final crowns were made from zirconia, selected to provide a combination of esthetics and durability. The improvement is noticeable. But ideally, the dentistry isn’t. That’s exactly what we want. Before After Is It Time to Replace Your Old Veneers or Crowns? Many patients assume they should only replace veneers or crowns when something breaks. That’s not necessarily the case. You may want to consider replacing older cosmetic dental work if your restorations have become: You may also simply feel that your dental work makes your smile look older than you feel. In some cases, replacing just a few aging restorations can refresh the appearance of the entire smile. Why See a Prosthodontist for Replacing Old Dental Work? Replacing existing cosmetic dentistry presents different challenges than starting with untouched teeth. The dentist needs to evaluate the existing restorations, the teeth underneath them, the bite, the surrounding natural teeth, and the patient’s overall smile before determining what should—and just as importantly, what should not—be changed. A prosthodontist receives advanced specialty training in restorative, cosmetic, implant, and reconstructive dentistry. At Geach Dental, we routinely treat patients with existing veneers, crowns, dental implants, and complex restorative dentistry. Our approach isn’t simply about making teeth look prettier. We want the final restorations to look natural, function properly, and integrate with the rest of the patient’s smile. Ready to Update Your Smile? If you had cosmetic dentistry completed years ago and your veneers, crowns, or implant restorations no longer look the way you want, you may not need to start over. Sometimes the right approach is simply to replace aging dental work with modern, natural-looking restorations.

Replacing Old Crowns, Veneers and Dental Implant Restorations for a Natural, Younger Smile

When Old Dental Work Makes Your Smile Look Older Even the highest-quality dental work doesn’t last forever. Over time, crowns, veneers and implant restorations can begin to show their age. They may chip, stain, or no longer match your surrounding teeth. As your gums naturally change over the years, restorations that once looked beautiful can begin to appear uneven or unnatural. Many patients tell us: This patient came to Geach Dental looking for exactly that. The Challenge This patient had several cosmetic concerns affecting the upper front teeth: Because the implant could not simply be moved, restoring this smile required careful planning and advanced prosthodontic expertise rather than simply replacing the crowns.  Why Replacing Old Dental Work Isn’t Always Simple Many people assume replacing an old crown or veneer is straightforward. Unfortunately, that’s not always the case. When dental implants, veneers, crowns and natural teeth all need to work together, every small detail matters: These complex cases are exactly why prosthodontists receive years of additional specialty training after dental school. Our Treatment Process Rather than immediately making new crowns, we first removed the existing restorations to evaluate the health of the underlying teeth and assess the position of the dental implant. Using digital smile design principles, we created custom provisional (temporary) restorations that allowed us to: These temporary restorations became the blueprint for the final result. Precision Craftsmanship Makes the Difference One advantage unique to Geach Dental is our in-office dental laboratory. Instead of sending everything to an outside lab, Dr. Adam Geach works directly with an experienced laboratory ceramist to customize: This close collaboration allows us to achieve an exceptional level of detail that is especially important in the highly visible front teeth. The Final Result Although the original implant position limited how much the gum line could be changed, nearly every other esthetic concern was corrected. The new restorations provided: The result is a smile that looks healthier, more balanced and significantly more natural. Healthy implant and tooth structure formed first: Final Restorations Placed: Do You Have Old Crowns, Veneers or Dental Implant Restorations? You may be an excellent candidate for replacing your existing dental work if you notice: Many patients are surprised how dramatically replacing aging dental work can refresh their entire appearance. Why Choose a Prosthodontist? Replacing cosmetic dental work is about much more than making new crowns. A prosthodontist is a dental specialist trained in complex restorative, cosmetic and implant dentistry. This advanced training is especially valuable when treating challenging cases involving: At Geach Dental, every smile is carefully planned with the goal of creating results that are beautiful, functional and built to last.
