Variations in planning fixed bridgework--a group of dentists at a case-based postgraduate course.
Variations in treatment planning and prescription have been described in relation to routine restorative dentistry. This study examined dentists' decisions regarding treatment planning for fixed bridgework. Fifty five dentists who attended a Continuing Education course on fixed bridgework were given standard information about a patient in the form of study casts, photographs of radiographs and a clinical history. They were asked to design a bridge where a previous one had failed and to complete a proforma which was returned to the course organisers in advance of the event. The response rate was 65%. The data showed wide variation in identification of features of diagnostic importance. Seventy percent of respondents chose to use again as abutments teeth which were extensively damaged and had failed to retain the previous bridge: while only 30% noted features of the occlusion which if left unchanged would have precluded a successful bridge from being made. A further feature was that nearly 70% chose to use multiple abutments to support the bridge. The implications of these results were discussed with respect to current concepts of bridge design.
