Iti Short Implants In The Posterior Area: A Retrospective Clinical Study With1to7Years Of Follow Up

Objective: The aims of this study are to evaluate the long-term survival rates of ITI shortdental implants in posterior areas and analyze the influence of factors on implant survival.Methods: In this study,sixty-nine patients received124short implants from January2006to June2013at the department of Oral and Maxillofacial Implantology,StomatologicalHospital in Yin Chuan City. Observe the survival situation and repaired effect of the shortimplants in the mouth. The potential influence of relevant factors, clinical factors,complications and prosthetic variables on implant survival and patient satisfaction wasstudied. Each implant failure was carefully analyzed. Through regular follow-up, clinicalexamination and radiological examination, evaluate the survival rate of short implants inWheeler assessment.Results: The mean follow-up period for the ITI short implants was45.6months. Theoverall survival rates of short implants were98.4%and97.1%for the implant andsubject-based analysis, respectively. During the observation period, two short implantsfailed,one of which was due to early implant failure and lost;one of which was due to lateimplant failure because of peri-implant mucositis. the patients were all satisfied with thetreatment effect after crown prosthese.Conclusions: Results of the present retrospective study show that high survival rates ofshort implants can be considered. Short implants supporting single crowns have their ownadvantages to conventional implants. One may conclude that a single crown supported by ashort implant is a predictable treatment modality if used under strict clinical indications.
