TOOTH REPLACEMENT
Fixed Prosthetic Solution on 4 or 6 Implants Canning Vale
A fixed prosthetic solution on 4 or 6 implants replaces a full arch of missing teeth with a permanently attached prosthesis. At Dentists @ Canning Vale, Dr Desmond Ng provides personalised treatment planning for patients seeking a stable, long-term implant solution.
For patients missing all or most of their teeth in an arch, a fixed prosthetic solution supported by four or six implants offers a stable, long-term alternative to removable dentures. Rather than resting on the gum or relying on adhesives, the prosthesis is permanently attached to implants anchored directly into the jawbone.
At Dentists @ Canning Vale, Dr Desmond Ng provides detailed assessments and personalised treatment plans for patients considering fixed implant-supported prosthetic treatment.
A fixed prosthetic solution on implants involves placing a small number of dental implants, typically four or six per arch, to serve as a secure foundation for a full-arch fixed bridge or prosthesis. The final restoration is screwed or cemented onto the implants and is not removed by the patient.
The number of implants used depends on several clinical factors assessed during treatment planning:
- The volume and density of available bone
- Whether bone grafting is required
- The design of the prosthesis
- The distribution of bite forces across the arch
- Individual clinical and anatomical factors
4-Implant vs 6-Implant Solutions
Dr Desmond Ng will assess which approach suits your bone structure, bite forces and treatment goals during your consultation.
4-Implant Solution
Uses four strategically positioned implants, including two angled at the rear of the arch, to support a full-arch fixed prosthesis. The angled placement maximises contact with available bone, often reducing the need for extensive bone grafting. Accessible for a wider range of patients, including those with some degree of bone loss.
Often suitable where bone volume is limited6-Implant Solution
Six implants provide additional support and improved load distribution across the arch. This approach may be recommended for patients with higher bite forces, specific bone anatomy, or where a more robust support structure is clinically preferred. The additional implants can enhance long-term stability of the final prosthesis.
Preferred for greater support and load distributionBenefits of a Fixed Prosthetic on 4 or 6 Implants
- Permanently fixed - the prosthesis is secured to the implants and does not need to be removed. No slipping, clicking or movement during eating or speaking.
- Improved function - eat a wider variety of foods with greater confidence and comfort compared to removable dentures.
- Natural appearance - custom-fabricated prostheses replicate the look of natural teeth, enhancing smile aesthetics and facial profile.
- Jawbone stimulation - implants function like natural tooth roots, stimulating the jawbone and helping to reduce progressive bone loss.
- Efficient use of implants - a clinically proven approach that minimises surgical complexity while maximising support and stability.
- Long-term durability - with proper oral hygiene and regular professional care, designed to provide a durable long-term outcome.
Am I a Suitable Candidate?
A fixed prosthetic solution on 4 or 6 implants may be suitable for patients who:
- Are missing all or most of their teeth in one or both arches
- Are experiencing ongoing problems with existing dentures
- Have adequate bone volume to support implant placement, or are suitable for bone augmentation
- Are in reasonable general health without contraindications to implant surgery
- Are non-smokers, or willing to cease smoking prior to treatment
- Are committed to good oral hygiene and regular dental maintenance
The Treatment Process
Treatment is carried out across several stages to ensure the best possible outcome. Your timeline will vary depending on individual clinical factors.
Consultation and Assessment - Dr Desmond Ng reviews your oral health, discusses your goals and takes a detailed medical and dental history to determine your suitability for treatment.
3D Imaging and Planning - Cone beam CT scanning provides precise data on bone volume, anatomy and optimal implant positioning to support accurate surgical planning.
Preparatory Treatment - Where required, extractions, bone grafting or other preparatory procedures are completed before implant placement to optimise the treatment site.
Implant Placement - Four or six implants are placed into the jawbone under local anaesthesia, with sedation available. A temporary prosthesis may be attached on the same day where clinically suitable, providing immediate function and aesthetics during healing.
Osseointegration - Over the following months, the implants fuse with the jawbone, a process called osseointegration, creating a stable biological foundation for the final prosthesis.
Final Prosthesis Fitting - Once osseointegration is confirmed, the final custom-made prosthesis is fabricated and attached to the implants, completing your full-arch restoration.
Frequently Asked Questions
What is the difference between 4 and 6 implants?
Four implants use angled posterior implants to maximise support with fewer fixtures, often reducing the need for bone grafting. Six implants provide additional support and load distribution and may be preferred in specific clinical situations. Dr Desmond Ng will recommend the most appropriate number based on your individual assessment.
Can I get teeth on the same day?
For suitable candidates, a temporary fixed prosthesis may be fitted on the same day as implant surgery, allowing you to leave the clinic with a functional smile. The final permanent prosthesis is fitted after the healing and osseointegration period is complete.
How do I clean an implant-supported fixed prosthesis?
Specialised cleaning tools such as interdental brushes, implant floss and oral irrigators are used to clean around and beneath the prosthesis. Our team will provide personalised homecare instructions at your fitting appointment and ongoing maintenance visits.
How long will the prosthesis last?
With proper maintenance and regular dental check-ups, implant-supported fixed prostheses are designed to provide a long-lasting outcome. The implants themselves, once fully integrated, may last many years with good oral hygiene and professional care.
Is bone grafting always required?
Not always. The angled implant placement used in 4-implant approaches is often designed to utilise available bone without grafting. However, some patients with significant bone loss may require grafting before or at the time of implant placement. This will be determined during your 3D imaging assessment.
