All on 4 bone reduction and dentures

Question

If all on 4 fails completley, would it still be possible to go back to full dentures.? Will you still have enough bone to hold the dentures after the bone reduction in the all on 4(alveolactomy)?

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.

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.

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.

Absolutely, if an All-on-4 implant-supported restoration were to encounter complications or fail completely, it is still possible to revert to full dentures. The transition back to dentures would depend on the condition of your existing oral structures.

While the All-on-4 procedure involves bone reduction (alveolactomy), leading to the placement of implants, a skilled implant specialist can often manage any potential complications. However, in the event of failure, the transition back to dentures would need to be carefully evaluated. The ability to hold dentures after bone reduction depends on the remaining bone structure and its stability.

It's important to emphasize that the success of implant procedures, including All-on-4, is significantly influenced by the expertise of the dental professional performing the treatment. With a highly skilled and experienced implant specialist, the likelihood of complications is minimized, and they can navigate any issues that may arise during the implant process.

If you have concerns or are considering transitioning back to dentures, I recommend scheduling a consultation with an implant specialist. They can assess your current oral health, bone structure, and discuss the best options tailored to your individual needs. Remember, success in dental implant procedures is often a collaborative effort between the patient and a skilled dental professional.
