Case Breakdown

Pre-operative Maxillary Arch

Pre-treatment intraoral view of the upper jaw showing severe dental breakdown and non-restorable remaining teeth.

Pre-operative Mandibular Arch

Pre-treatment intraoral view of the lower jaw exhibiting extensive tooth loss and compromised occlusal integrity.

Final Prosthetic Restoration

Delivery of custom full-arch fixed implant bridges, restoring natural smile aesthetics, facial profile, and optimal masticatory function.

Post-operative CBCT Radiograph

Treatment Process

Case Overview

This full-mouth reconstruction was performed by Dr. Teng Lizhao, Dean of Chengdu Anyu Dental Implant Hospital, who holds a Ph.D. in Biomedical Engineering from Sichuan University.

The patient presented with extreme oral breakdown—a state of severe edentulism where nearly all remaining teeth were non-restorable. Beyond rendering normal chewing nearly impossible, complete or near-complete tooth loss carries serious long-term health risks, including temporomandibular joint (TMJ) disorders, digestive problems, nutritional deficiencies, impaired speech, and severe facial collapse due to jawbone resorption. Because the remaining oral tissue offered poor support even for traditional removable dentures, the patient sought a permanent fixed implant solution with Dr. Teng.

Surgical Strategy: Targeted Multi-Implant Reconstruction

Many patients falsely assume that full-mouth replacement requires 28 individual implants for 28 teeth. Dr. Teng designed a tailored biomechanical solution using fixed full-arch bridges:

  • Strategic Implant Placement: Based on the distinct anatomical conditions of the patient's upper and lower jaws, Dr. Teng strategically inserted 7 implants in the maxilla (upper jaw) and 6 implants in the mandible (lower jaw).
  • Biomechanical Efficiency: Using an advanced multi-implant protocol similar to the All-on-6/All-on-X technique, Dr. Teng maximized existing bone density to create a highly stable foundation without unnecessary bone grafting.
  • Full-Arch Prosthetic Delivery: Custom-engineered full-arch bridge restorations were securely attached to the 13 total implants, successfully rebuilding two complete rows of teeth.

Final Treatment Outcome

The comprehensive rehabilitation fully restored the patient's oral function, facial proportions, and smile aesthetics:

  • Functional Recovery: Restored firm biting force, allowing the patient to enjoy a normal, nutritious diet again while relieving digestive pressure.
  • Facial Aesthetic Restoration: Rebuilt collapsed vertical dimension, providing structural support for lip and cheek profile to correct the sunken facial appearance.
  • Speech & Life Quality: Restored clear articulation and natural speech, delivering a life-changing transformation in both health and confidence.

FAQs

What does "edentulism" mean, and why is it harmful?

Edentulism refers to complete or near-complete loss of teeth in a jaw. Left untreated, it severely impairs chewing and speech, causes jawbone loss and sunken facial features, and increases the risk of digestive and nutritional issues.

Do I need 28 implants to replace all my teeth?

No. A full-arch fixed restoration usually requires only 4 to 8 strategically placed implants per jaw to support a full set of teeth securely.

Why choose full-mouth implants over traditional removable dentures?

Unlike removable dentures that slip, restrict eating, and accelerate bone loss, implant-supported bridges are fixed, function like natural teeth, and help preserve jawbone density.

Can I get full-mouth implants if I have moderate bone loss?

Yes. Modern multi-implant protocols (such as All-on-6) strategically angle and position implants into your strongest existing bone, often reducing or eliminating the need for bone grafting.

How many implants are typically needed for full-mouth reconstruction?

Rather than placing one implant per tooth, standard full-arch protocols typically utilize 6 to 8 implants for the upper jaw and 4 to 6 implants for the lower jaw. In this specific case, Dr. Teng strategically placed 7 implants in the upper jaw and 6 implants in the lower jaw to achieve optimal stability.

How long do full-mouth dental implants last?

With proper surgical execution, good daily oral hygiene, and routine dental checkups, the implant posts integrated into your jawbone can last for decades or even a lifetime.
