Presenting Clinical Problem
A patient presented to Greenvale Dental House with severe tooth decay affecting multiple teeth across the arch, which was making eating and speaking difficult. Assessment determined that extraction and full-arch replacement was the appropriate approach, and All-On-4 was planned.
- Severe tooth decay affecting multiple teeth across the arch
- Compromised oral health and tooth structure
- Functional difficulties with eating and speaking
- Assessment indicating extraction and full-arch replacement
Primary objective: full-arch fixed implant restoration using the All-On-4 technique.
Treatment Approach
Phase 1: Assessment and treatment planning
- Comprehensive oral examination and radiographic assessment, including a CT scan
- Evaluation of the extent of decay and whether teeth were salvageable
- Discussion of All-On-4 alongside attempting individual tooth restoration
- Assessment of bone quality and quantity for implant placement
Phase 2: Extraction and implant placement
- Removal of the severely decayed teeth under appropriate anaesthesia
- Surgical placement of four implants using the All-On-4 technique
- Attachment of an immediate temporary prosthesis on the day of surgery
- Post-surgical care instructions and monitoring of healing and integration
Phase 3: Final prosthesis fabrication and delivery
- Impressions taken for the final fixed prosthesis
- Framework and tooth-arrangement design
- Try-in appointment to verify fit, function and appearance
- Delivery of the final All-On-4 prosthesis and long-term maintenance advice
Clinical Outcome
All-On-4 treatment was completed with four implants placed and a fixed prosthesis delivered after the healing period. Treatment took place across multiple appointments over several months, and the patient followed the recommended oral-hygiene practices afterwards.
Individual results vary. Success depends on bone quality, implant integration and general health, and not everyone is a suitable candidate. Fixed prostheses need regular professional maintenance and careful home care to protect the gums and bone around the implants. Suitability can only be confirmed at a clinical consultation.
Frequently Asked Questions for Greenvale and Craigieburn Patients
Why remove teeth instead of filling the cavities?
When decay is extensive across multiple teeth, individual restoration can be less predictable than full-arch replacement, and severely decayed teeth often need extraction regardless. All-On-4 offers a comprehensive option when most teeth are affected. The decision depends on the extent of decay and your individual circumstances.
Will I be without teeth during treatment?
All-On-4 typically includes an immediate temporary prosthesis fitted on the day of surgery, so you are not left without teeth. The temporary stays in place during the three-to-six-month healing period, with dietary restrictions, until the final prosthesis is delivered.
Can tooth decay affect dental implants?
Implants themselves cannot develop cavities, as they are made from titanium and ceramic. However, inadequate hygiene around them can lead to peri-implantitis (inflammation of the gum and bone around an implant), which can compromise the result. Regular professional maintenance and daily home care are essential.
