For patients who have lost all the teeth in their mouth or whose existing teeth need to be extracted, full-mouth dental implants are the healthiest and most permanent restoration alternative. In this treatment the All-on-4 or All-on-6 techniques are generally preferred.
What Is the Difference Between All-on-4 and All-on-6?
The main purpose of both methods is to place a full-mouth fixed prosthesis on implants placed in a certain number into the jawbone:
- All-on-4: Particularly in patients with extensive bone loss in the posterior region, this is the placement of a fixed prosthesis on 4 implants inserted at an angle. It generally allows temporary teeth to be fitted on the same day.
- All-on-6: It is preferred in patients whose bone support is better and for whom distributing the chewing force over 6 implants would be more stable.
All-on-4 and All-on-6 Treatment Process
Treatment planning is carried out with the help of 3-dimensional tomography. On the day the implants are placed, temporary fixed teeth are prepared and screwed in. The patient is never left toothless throughout the healing process (approximately 3 months). When bone fusion is complete, permanent zirconia or metal-supported porcelain bridges are screwed in and the patient regains fixed teeth that can be used for many years.
