Although dental implants have been successful in treating the maxilla (upper jawbone) and mandible (lower jawbone) that have severely damaged dental tissue, their curative effect was limited for some patients. Thanks to the developments in implant dentistry, there has been a change from the early paradigms established.
Instead of the usual 6 months for the Maxilla and 3 months for the Mandible for loading the prosthesis after the implants are placed in the jawbone, it can provide immediate loading of the implants in certain clinical situations, thanks to the advances in biology and technical developments. All-on-four treatment, which has given successful results in both short-term, long-term and retrospective studies, leaves traditional prostheses, which are a routine treatment alternative in completely edentulous patients, and is ideal for edentulous jaw treatment.
Compared to the traditional prosthesis, the All-on-four treatment has many advantages. Angled posterior implants prevent anatomical problems and are a much longer-term and high-quality solution. Bone-fixed implants reduce the posterior console. Eliminates bone grafts in edentulous areas in most cases. Although the success rates are high, it is easier to clean, functional and more aesthetic in appearance because of its better biomechanics. The final restoration may be fixed or removable. Low cost due to fewer implants. It is very sensitive to technique and requires a very delicate detail and careful process such as detailed pre-operative preparation, CAD/CAM, surgical splint.
The steps of the all-on-four treatment are approximately as follows;
After the selection of the case that meets the conditions, the inclusion criteria, the planning of implant placement using the All-On-4 Guide, and the protocols made after the implant placement process, the prosthetic phase begins. Mouth impression is taken and final impressions are verified after integration is completed after GC resin splinting to ensure, splinting with GC resin. All-ceramic Zirconia bridge is designed with CAD/CAM technology. Again, a milled titanium frame is produced for the use of a CAD/CAM zirconia bridge or for veneer (crown). All veneers are adhered to the zirconia frame. The implant supported zirconia bridge becomes a bonded frame with individual crowns. Treatment of complete edentulism with the atrophic maxilla and mandible All-on-Four protocol has been a perceptible success, a promising treatment modality for patients with severely damaged teeth.
