The Association Between Buccal Mucosa Thickness and Periimplant Bone Loss and Attachment Loss: A Cross-Sectional Study.

PURPOSE: The aim of this study was to assess if there is an association between buccal mucosa thickness and periimplant attachment loss after 1 year of function.

MATERIALS AND

METHODS

A total of 28 patients (14 periimplantitis implants and 14 healthy implants) were included. The buccal mucosal thickness was assessed using K-files at 3 mm apical to the soft tissue margin of the implant. Probing depth, recession (REC), clinical attachment level (CAL), bleeding on probing, and radiographic bone loss on mesial and distal sites of the implant were recorded.

RESULTS

The data showed that there was a statistically significant difference in midfacial REC between thin and thick buccal mucosa groups. However, the CAL was not statistically significant different between both groups. In addition, there was no statistically significant difference in mesial and distal bone loss between implants with thin and thick mucosa.

CONCLUSION

When the midfacial soft tissue thickness was thin, the midfacial REC was greater and the CAL also tended to be higher. There was no association between buccal mucosa thickness and periimplant bone loss on mesial and distal sites of the implant after 1 year of function.
