Association between Gingival Biotype and Crestal Bone Loss in Implants Placed in Anterior Maxilla.

Abstract

Background: When bone loss occurs around an implant, it can cause esthetic compromise, which might affect the tissue level design. Thus, bone level design implants are usually preferred if a natural emergence profile is important. The gingival biotype had been identified as a significant factor in the stability of crestal bone.

Aim: The aim of the current study is to analyze the gingival biotype and crestal bone in implants placed in anterior maxilla.

Materials and methods: retrospective study was conducted using the case records of patients in University Hospital. Data on the gingival biotype and crestal bone loss in implants placed in anterior maxilla were collected (sample size = 96 patients) and analyzed for association with age and gender by descriptive statistics and chi-square association.

Results: In thick gingival biotype 59.3% of the cases showed no crestal bone loss and 5.2% of the patients showed only 1 mm of bone loss, but in case of thin gingival biotype, 16.6% of patients had 1 mm of bone loss, 5.2% of them has 2 mm of bone loss, and 1% of them had bone loss of 3 mm and above, with a significant p value of 0.02 (less than 0.05) showing a strong association between gingival biotype and crestal bone loss around implants.

Conclusion: It can be concluded that there exists a significant association between gingival biotype and crestal bone loss around implants placed in anterior maxilla.
