The influence of “conical plus octagonal” internal connection on implant survival and success rate: a retrospective study of 66 fixtures.

The influence of “conical plus octagonal” internal connection on implant survival and success rate: a retrospective study of 66 fixtures. J Biol Regul Homeost Agents. 2016 Apr-Jun;30(2 Suppl 1):49-54 Authors: Lopez MA, Andreasi Bassi M, Confalone L, Gaudio RM, Lombardo L, Lauritano D Abstract Implant oral rehabilitation has become one of the most successful dentistry techniques over the last 30 years. However, peri-implantitis is the most important complication in implant dentistry. Peri-implantits can be caused by inadequate implant-abutment connections (IAC). The aim of our study is to evaluate the influence of “conical plus octagonal” (i.e. I-Fix connection) on implant survival and success rate. All the implants included in this study were of a completely new type (I-Fix implants and abutments by FMD Falappa Medical Devices S.p.A. Rome, Italy). Sixty-six implants were inserted in males and females. The implants were of different diameters and lengths, inserted both in the mandible and in the maxilla with immediate or delayed loading, with guided bone regeneration (GBR), and post-extractive surgery. All implants were provided with I-Fix connection, 64 abutments using passing screws and 2 using full screws. None of the 66 implants were lost (i.e. survival rate - SVR = 100%). Cox-regression analysis demonstrated that diabetes (p=0.0074), GBR (p=0.0115), maxilla (p=0.0117) and smoking (p=0.0194) have a statistical significant impa...
