Abstract

Background: To accomplish successful esthetic outcome, it would be an advantage if some pre-implant placement conditions could be identified which would predict soft and hard tissue outcomes post-implant placement. This study was designed to evaluate the influence of 1) height of mid-buccal keratinized mucosa at implant surgery and 2) thickness of mid-buccal bone after osteotomy on the amounts of mid-buccal mucosal recession and bone loss during the first year after implant treatment. This report presents the initial 3-month follow-up.

Materials and methods: Nine patients scheduled for surgical placement of a total of 11 single-staged implants, without adjacent teeth and planned for fixed crown restoration, were recruited for this study. The height of keratinized mucosa and thickness of buccal bone after osteotomy were measured prior to implant placement. Upon crown insertion and three months later, mid-buccal probing depth, soft tissue height, levels of mucosal margin and bone crest were measured.

Results: The height of the keratinized mucosa decreased from 5.8 ± 3.0 mm to 2.2 ±1.5 mm and 2.4 ±1.9 mm from time of surgery to crown insertion and 3 months later. Calculations of correlations showed tendencies indicating that with decreasing height of the mid-buccal keratinized mucosa and decreasing thickness of the mid-buccal bone after osteotomy there were more mid-buccal mucosal recession and bone loss from crown insertion to 3 months later. However, most of these relationships did not reach statistical significance.

Conclusion: This 3-month report identified some pre-implant placement conditions that seem to predict relevant soft and hard tissue outcomes post-implant placement.
