All On Four Treatment
The All-on-4 treatment concept is a prosthodontic procedure which is best for patients with significant tooth loss or decay and for people whose bone loss in the jaw area prevents them from getting conventionally oriented dental implants. Often, tooth loss is accompanied by loss of the jaw bone which poses the problem of reconstruction of the jaw bone requiring bone grafting. The most ideal way to evaluate the bone is by a CBCT scan. The All-on-4 protocol is for at least four implants to be placed in a jaw. The implant is placed in front of the maxillary sinus in the upper jaw and in front of the mental nerve in the lower jaw . This will allow a molar tooth to be cantilevered posterior resulting in a denture or bridge with approximately 12 teeth.
