The Periodontal Health of Abutment Teeth Retaining Overdentures: A Systematic Review

Abstract

Objective: This systematic review aims to evaluate the effect of the overdenture on the periodontal state of the dental roots supporting the prosthesis.Sources: This report followed the PRISMA Statement. A systematic search was done using a search equation in different databases: PubMed/MEDLINE, Web of Science, EBSCOhost, and Science Direct. The search was limited to publications in English and French.Study selection: All observational clinical studies that were interested in evaluating the effect of the overdenture on the periodontal health of abutment teeth were included in our systematic review. Of the 694 articles initially identified, eight studies met our inclusion criteria and were included in the systematic review.Results: There was no significant change in the alveolar bone surrounding the pillar root. The difference in pocket depth and dental mobility was insignificant. However, the loss of attachment increased over time and the height of the attached gingival decreased, especially in the mandible. This decrease was statistically significant.
