Resin Template for Guiding Preparation in Resin Bonded Fixed Partial Denture – A Case Report

ABSTRACT

@#Resin Bonded Fixed Partial Denture (RBPFD) is a popular treatment for tooth preservation. Mechanical retention is a problem for RBFPD, where debonding is the main cause of failure. RBFPD preparation is minimal invasive. It removes undercut and tooth structure that supports retention so that single insertion guide can be achieved. This preparation was achieved by using surveyor on diagnostic cast, but there was a concern how to copy the surveyed cast to intraoral. Resin template method as a preparation guide was useful to avoid excessive tooth removal. RBFPD design was marked by using pencil on the diagnostic cast. The cast was surveyed to get the preparation designed and prepared by using milling device surveyor and burs. The template was made on the cast. Separator was applied and resin template was built along the margin until the occlusal line angle. The abutment teeth were etched and bonded. Bonding procedure was done on template. The template was placed on the teeth and polimerized. Abutment teeth preparation were done according to the cast with the bur contact simultaneously with the template’s margin and finishing line. Resin template has better accuration and adaptation, easier made and efficient, also prevent excessive tooth removal and control the preparation, mechanical retention can be achieved for RBFPD restoration longevity. Resin template is useful because preparation can be transfered from diagnostic cast to intraoral accurately.
