All on 4 bone reduction and dentures

While the simple answer is "yes", the reality is that the denture resting on ridges of bone that have been reduced for the All on Four procedure will be significantly less stable. Adhesives will be very important at that point, but to be honest, I have never seen a case where the All on Four procedure didn't work or last. If an implant (or several?) failed, it simply gets replaced. The replacement may be in a new location or angled differently, and a new prosthetic would need to be created.

So, "yes", one COULD go back to a denture, but I have never seen that happen.

About full-mouth restoration procedures, four implants are placed in each arch using the all on 4 technique; no grafting is necessary. Four implants are present. There exist two in the front of the mouth that are vertical. The other two are located at the midpoint of the tongue.
To address your inquiry, we kindly request you to upload your X-ray panoramic film here. Implant failures can be attributed to various factors, including improper surgical techniques, incorrect selection of implants, and patient-related factors. Despite the loss of implants, if an adequate amount of bone is present, implants can be reinserted. If there is insufficient bone, grafting surgeries may be performed. To determine the appropriate treatment approach, advanced radiological imaging (tomography) and clinical examination are necessary.

Hello, such treatments are not treatments that are made with the foresight that the implants will be completely lost, each treatment has its pros and cons. In implant-supported fixed prosthesis treatments, if the treatment has been done with the right planning and the patient has the right oral hygiene, the success rate in such treatments is as high as 98%.If we think about complications, of course, bone reduction is an element that reduces the retention of the prosthesis, but the possibility of loss of all implants in patients with bone reduction for implant treatment is very rare.
