Does Implant Fixed Restoration Can Reverse The Physiological Route Of Mandibular Bone Resorption Of The Posterior Edentulous Area For The Completely Edentulous Patients?: Systematic Review

Abstract

Introduction: To compare the bone height changes of the posterior mandibular edentulous area of fixed implant prosthesis versus that of removable implant overdentures. Materials & Methods: An electronic search was performed using PubMed and Cochrane CENTRAL databases for articles published in English till the end of November 2016. Inclusion criteria were randomized clinical trials (RCTs) and prospective cohort studies (PS) which measured the changes of the height of the posterior edentulous area of the mandible. Two reviewers independently screened titles and abstracts, made data extraction and appraised the quality of included studies. Results: From a total of six identified relevant studies, two randomized clinical trials and two prospective cohort studies fulfilled the inclusion criteria. The authors of the included studies concurred to bone resorption as a result of removable prostheses and advocated to fixed prostheses as it allow for preservation of the bone height and even bone apposition. Conclusion: the implant fixed prosthesis is superior over the implant removable overdentures regarding the preservation of the posterior edentulous bone height.
