[Evaluation of periodontal health of prosthetic abutments. Pilot study about 100 abutments of crowns and bridges].

BACKGROUND: The confection of a fixed prosthesis finds its indication in response to the patient's aesthetic and/or functional whose requirements are stronger in terms of satisfaction. This involves maintaining the stability of prosthetic reconstructions on a sufficiency long time. To achieve this, the preservation of periodontal health of the prosthetic abutments occupies a special choice.

PURPOSE: The aim of this study was to evaluate the periodontal health of fixed prosthesis abutment.

MATERIALS AND METHODS: Thirty-nine patients having fixed prosthesis in the mouth for more than one year participated in our study. Ultimately, 38 single crowns and 27 seven bridges based on 100 abutments have been recorded. After an interview, clinical and radiographic examination was performed. It was to assess the level of oral hygiene, the health of the superficial and deep periodontal abutment using OHIS index of Green and Vermilion, periodontal index of Russel and mobility index of Mühlemann.

RESULTS: On the 100 abutments examined, gingivitis (14%), gingival recession (13%), bone osteolysis (29%) and mobility (5%) were recorded. In addition, about 60% of patients had inadequate oral hygiene and less than 30% of them had a regular prosthetic maintenance.

CONCLUSION: From this study, it appears that complications affecting periodontal prosthetic abutments are essentially bone lysed (29%), gingivitis (14%) and gingival recessions (13%).
