Evaluation of the Periodontal Status of Abutment Teeth in Removable Partial Dentures
Correia, André Ricardo Maia / da Silva Lobo, Fábio Daniel / Miranda, Mónica Célia Pereira / Framegas de Araújo, Filipe Miguel Soares / Santos Marques, Tiago Miguel
The purpose of this study was to evaluate whether the use of removable partial dentures affects the periodontal status of abutment teeth. An observational crosssectional study was done on a sample of patients rehabilitated with removable partial dentures (2010 to 2013). At a recall appointment, a clinical examination was done to collect data related to the rehabilitation and periodontal status of the abutment teeth. Of 145 invited patients, 54 attended the requested follow-up appointment (37.2%). Mean patient age was 59.1 years, and the study population was 42.6% male and 57.4% female. The mean follow-up time for the prosthesis was 26 months. Abutment teeth had higher values in all periodontal variables (P < .001). Occlusal clasps had the worst results in relation to clasps with a gingival approach (P < .005). Significant differences were also found in mandibular abutment teeth of Kennedy Class I and II compared to Class III (P < .048). The periodontal status of the abutment teeth of removable partial dentures is affected by these rehabilitations. A recall program for these patients involving removable prosthodontics and periodontology appointments is mandatory.
