Influence of Mucosal Tissue Thickness on Placement of Implant at Crestal, Sub-crestal and Supra-crestal Level: A Literature Review

Introduction: Dental implants are preferred for replacing missing tooth. They form sturdy connection to bone by osseointegration. During this, bone remodelling occurs which results in bone loss. Expected normal bone loss is 0.5 mm to 1 mm. Crestal bone level is the important factor in long term implant stability and success. According to studies if mucosal tissues are thinned to <2 mm, there is significant crestal bone resorption, compared with implants placed with >2mm thickness. Linkevicious et al. performed clinical controlled study and confirmed same. Many recent studies have similar results. This literature review is framed to understand the effect of mucosal thickness on Sub-crestal, Supra-crestal and Crestal level of implant placement & its relation to amount of crestal bone loss. Aim: To evaluate how effect of mucosal tissue thickness at crestal bone level around dental implant. Methodology: Literature was selected by searching in online journals. Keywords used were “dental implants”, “vertical mucosal thickness”, “peri-implant tissues, “crestal-bone loss”, “marginal-bone loss”, “implant-abutment interface”, “biologic width”. Articles published in English Language was selected from year 1992-2019. Rationale/Hypothesis: Recent clinical researches proved that soft tissue thickness is an important factor in preserving crestal bone around implants
