STATEMENT OF PROBLEM: To my knowledge, there is no systematic review of crestal @entity604 (CBL) around submerged and nonsubmerged dental implants. PURPOSE: The purpose of this review was to systematically assess CBL around submerged and nonsubmerged dental implants. MATERIAL AND METHODS: The addressed focused question was, "Does crestal and subcrestal placement of dental implants influence crestal bone levels?" Databases were searched from 1986 through October 2015 using different combinations of the following keywords: crestal, sub-crestal, @entity604 , dental implant, submerged, and nonsubmerged. Reference lists of potentially relevant original and review articles were hand-searched to identify any further studies. Letters to the editor, case reports, commentaries, studies on platform-switched implants, and studies published in languages other than English were excluded. RESULTS: In total, 13 studies (6 @entity1 and 7 animal), which were performed at universities, were included. In the @entity1 studies, the number of @entity1 ranged from 8 to 84 individuals. The follow-up period ranged from 1 to 5 years. CBL at the test sites ranged from 0.17 mm to 0.9 mm and at control sites from 0.02 mm to 1.4 mm. Five @entity1 studies reported no significant difference in CBL around implants placed at the test and control sites. All animal studies were performed in @entity235 with a mean age ranging from 1 to approximately 2 years. The follow-up period ranged from 2 to 6 months. Four animal studies reported no significant difference in CBL around submerged and nonsubmerged implants. CONCLUSION: No significant difference in CBL was found around submerged and nonsubmerged dental implants.
