Alveolar Crest Bone and its Comparison with Single-Tooth Reconstructive Implants Download PDF

Introduction Dental implants are the most interesting method of treatment which have triggered a great revolution in dental treatments. Implant-supported cantilever prosthesis is one of the considerable treatments. Previous studies have discussed the point that these prostheses are the focus of the pressure. However, some studies put emphasis on the clinical success of these prostheses. Materials and methods In the present study, 52 samples were studied 26 of which had a treatment with implant-supported cantilever design and the other 26 had a treatment with single-tooth reconstructive implant design. Patients whose treatment was less than six months ago were eliminated from the study. The rate of alveolar crest bone loss around implant-supported cantilever prosthesis and ordinary implants were assessed by specialists in periodontal surgery using radiographs. Findings There was no a significant relationship between variables such as presence or absence of cantilever, gender, age, bone type and length of implant and the variable rate of bone loss. However, there was a relationship between rate of bone loss and the time factor; in such a way that as more time passed, an increase was seen in the rate of bone loss. The rates of bone loss in Ivory and Ritter implantation systems were significantly higher than others. Conclusion In case of observation of technical principles during the implantation surgery and prosthesis placement, using implant-supported cantilever prosthesis could be a verified method. Of course, it is essential to conduct more researches that focus on this issue.
