Can Implant-Supported Dentures Replace Multiple Failing Teeth in Melbourne?
Case Note ID: Dec-2024-ISD
Location: Dental House Group (serving Melbourne’s north and west)
Primary Treatments: Full Arch Dental Implants, Implant-Supported Denture Prosthesis
Supporting Technology: Dental Implant Systems, Surgical Planning, Prosthetic Fabrication, 3D Imaging
Presenting Clinical Problem
A patient presented with multiple failing teeth requiring extraction and full arch rehabilitation with implant-supported prosthesis. The clinical presentation included multiple teeth with advanced breakdown and structural compromise beyond restorative repair, teeth deemed unrestorable due to extensive decay, fracture or periodontal breakdown, need for multiple tooth extractions across both dental arches, and patient requirement for fixed tooth replacement solution following extractions.
The primary clinical objectives were to remove all unrestorable teeth compromising oral health and function, place dental implants in both upper and lower arches to serve as prosthetic anchorage, fabricate implant-supported denture prostheses for permanent tooth replacement, and restore chewing function and aesthetics through fixed implant-retained restorations. Treatment planning involved comprehensive evaluation, multiple tooth extractions, placement of six dental implants per arch, and fabrication of implant-supported full arch prostheses.
Treatment Plan & Clinical Process
Phase 1: Comprehensive Assessment and Surgical Planning
- Complete dental and radiographic examination evaluating all teeth
- 3D imaging assessment of jaw bone quantity and quality for implant planning
- Identification of unrestorable teeth requiring extraction
- Medical history review and implant suitability evaluation
- Treatment planning for implant positions, angulation and prosthetic design
Phase 2: Extractions and Implant Placement
- Surgical extraction of all unrestorable teeth in planned sequence
- Healing period following extractions if immediate implant placement not indicated
- Surgical placement of six dental implants per arch at planned positions
- Temporary prosthesis provision during implant integration period if appropriate
- Osseointegration healing period typically 3-6 months following implant placement
Phase 3: Prosthetic Fabrication and Delivery
- Assessment of implant integration and healing completion
- Impression procedures capturing implant positions for prosthetic fabrication
- Fabrication of implant-supported full arch denture prostheses
- Try-in appointments for fit, bite and aesthetic verification
- Final prosthesis delivery, attachment to implants and function verification
Clinical Outcome
Treatment was completed over several months including healing periods between surgical and prosthetic phases. Multiple failing teeth were extracted, six dental implants were placed in each arch, and implant-supported full arch dentures were fabricated and attached to implants. The implant-supported prostheses provided fixed tooth replacement following multiple extractions.
Individual results vary. Full arch implant treatment requires extensive time, multiple procedures and substantial financial investment. Not all patients have adequate bone for implant placement without grafting. Individual implants can fail requiring replacement. Some patients experience surgical complications including infection, nerve injury or sinus issues. Prosthetic complications including loosening or fracture can occur requiring repair. Maintenance appointments are essential for long-term success. No guarantees can be made about outcomes.
Frequently Asked Questions for Melbourne Patients
What is the difference between implant-supported dentures and regular dentures?
Implant-supported dentures attach to dental implants surgically placed in jaw bone, providing stable fixed retention. Regular removable dentures rest on gum tissue without implant support and can move during eating or speaking. Implant-supported options provide superior stability but require surgical implant placement and higher cost. Some implant dentures are fixed whilst others are removable but implant-retained.
How many implants are needed for full arch replacement?
Full arch implant-supported prostheses typically require 4-6 implants per arch depending on bone quality, prosthesis design and bite forces. Fewer implants may be adequate in some cases whilst others require additional implants for adequate support. Assessment of bone conditions and prosthetic requirements determines optimal implant number for individual cases.
How long does full arch implant treatment take?
Full arch implant treatment typically requires 6-12 months from initial consultation to final prosthesis delivery. This includes assessment, extractions if needed, implant surgery, 3-6 month healing period for osseointegration, and prosthetic fabrication appointments. Immediate loading protocols can reduce timeline in selected cases but conventional healing periods provide most predictable outcomes. Complex cases requiring bone grafting extend treatment time.
