Wider Applicability with Bone Grafting
Although the All-on-4 method can be applied without bone grafting in many cases, the treatment plan can be expanded with bone graft (bone augmentation) support when jawbone density is insufficient.
This allows:
- Patients who were previously told they were "not suitable for implants," and
- Individuals with advanced bone loss
to benefit from All-on-4 treatment through personalised planning. Based on detailed radiological assessments and digital measurements, the safest and most predictable approach is determined for each patient.
Step-by-Step All-on-4 Treatment Process
At the initial stage of the procedure, 4 implants are placed at carefully determined positions within the jawbone. These implants form a stable base for the fixed prosthesis. Following this, Multi-Unit abutments are attached to each implant to allow the prosthesis to be positioned correctly for optimal function and appearance.
While the implants integrate with the bone, high-quality temporary teeth supported by a metal framework are provided, enabling patients to maintain their daily routines and social interactions with comfort and confidence. This interim phase allows patients to smile, speak, and carry out everyday activities without interruption.
After approximately 4–6 months, once healing is complete and the patient returns for the second visit, the temporary prosthesis is removed. The final prosthetic framework is then prepared on the existing Multi-Unit abutments, completing the full-arch construction.
In the final step, zirconium crowns are fitted onto a high-precision titanium framework. This specially designed titanium base supports bone preservation, promotes even distribution of biting forces, and contributes to a natural-looking and durable outcome.
As a result, patients achieve a renewed smile that is strong, stable, and natural in appearance.
Multi-Unit Abutment Approach in All-on-4 Treatments
In All-on-4 dental implant treatments, a multi-unit abutment system is used to ensure accurate positioning of the fixed prosthesis and long-term stability.
This system:
- Enables the prosthesis to sit in an ideal position on angled dental implants,
- Helps distribute chewing forces evenly across the implants,
- Contributes to more successful outcomes both functionally and aesthetically.
Following implant placement, temporary fixed teeth are applied to allow patients to continue their daily and social lives comfortably during the healing process. Once the dental implants have fully integrated with the bone, permanent prostheses offering long-lasting use, strong chewing function, and a natural appearance are placed.
