Summary

NDI represent an advisable treatment option when the mesio-distal space is compromised. In a recent retrospective study with a follow-up of 8 years in which they wanted to evaluate the long-term survival, complications, peri-implant conditions, marginal bone loss, and patient satisfaction of fixed dental prostheses supported by NDI in the posterior area. They observe a survival rate of 97% and absence of prosthetic complications after the study period time. More recently, Souza et al. performed a prospective randomized split mouth study with 3 years follow-up with the aim of comparing marginal bone level, implant survival and success rates and prosthesis success rates of NDI and SDI placed in the posterior area of the mandible to support single prosthesis. They observed an implant survival rate of 100% for both groups at 1 and 3 years. The prosthesis success rate at 1 and 3 years was of 95.4% and 100%, respectively. NDI present a high survival rate on the evaluated studies. Therefore, the aim of the first study is to compare the patient related outcomes, implants and prostheses success and survival rates of pure titanium NDI versus SDI with simultaneous bone regeneration in narrow alveolar ridges at posterior areas of the maxilla and the mandible.
