title: The periodontal response to cantilevered resin-bonded bridgework.
abstract: This study investigated 84 cantilevered resin-bonded bridges (CRBB) in 60 patients. These CRBB (single retainer, single pontic) had been in place for an average of 43.6 months. Periodontal health was assessed on abutment teeth and contralateral control teeth. Periodontal indices utilized were Plaque Index (PI), Gingival Index (GI), Bleeding Index (BI), Pocket Depth (PD) and mobility. The marginal adaptation, the gingival extension of the retainers and the presence or absence of caries around each retainer margin were also assessed. Information about the history of debonding was collected and a success rate of 93% was reported. PI, GI and mean PD compared statistically significantly, less favourably, with scores of the control teeth. Marginal adaptation of the retainers was of a high standard and caries did not appear to be a problem.
