\n\nMethods: Records of 50 consecutive patients treated with subcrestally placed dental implants grafted with a xenograft (Group A) and 50 consecutive patients with subcrestally placed dental implants without any grafting material (Group B) were reviewed. For each implant, the radiographs after placement were compared to images from the last follow-up visit and evaluated regarding the following: 1) degree of subcrestal positioning of the implant, 2) changes of marginal hard-tissue height over time, and 3) whether marginal

hard-tissue could be detected on the implant platform at the follow-up visit.\n\nResults: The mean marginal loss of hard tissues was 0.11 +/- 0.30 mm for Group A and 0.08 +/- 0.22 mm for Group B. Sixty-nine percent of the implants in Group A and EPZ-6438 price 77% of the implants in Group B demonstrated hard tissue on the implant platform. There were no statistically significant differences between the groups regarding marginal pen-implant hard-tissue loss.\n\nConclusion: The present study fails to demonstrate that grafting of the remaining osseous wound defect between the bone crest and the coronal aspect of the implant has a positive effect on marginal pen-implant hard-tissue

changes. J Periodontol 2011;82:234-242.”
