Abstract
Resin Bonded Fixed Partial Denture (RBFPD) is a popular treatment for tooth preservation. Mechanical retention is crucial for RBFPD, where debonding is the main cause of failure. RBFPD preparation is minimally invasive. It removes undercut and tooth structure that supports retention so that a single insertion guide was achieved. This preparation is achieved by using surveyor on the diagnostic cast, but there is a concern on 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. The separator was applied and the resin template was built along the margin until the occlusal line angle. The abutment teeth were etched and bonded. Bonding procedure was done on the template. The template was placed on the teeth and polymerized. Abutment teeth preparation were done according to the cast with the bur contact simultaneously with the template’s margin and finishing line. Resin templates have advantages compared to silicone and vacuum form template. Silicone template is thicker and harder to detect the preparation margin. Vacuum form template was less adaptive because of space and step. 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 transferred from diagnostic cast to intraoral accurately.
Highlights
The Resin Bonded Fixed Partial Denture (RBFPD) has become a well-known treatment when the abutments are relatively intact or when preservation of tooth structure is needed [1]
The RBFPDs have been attractive for patients and dentists because of the minimal loss of tooth structure during tooth preparation
RBFPD was proposed as the patient was young and she had a wide pulp chamber and the patient consented with the treatment.The treatment plan was the same like previous case to achieve single insertion guide with a good resin template for RBFPD (Figure 1117)
Summary
The Resin Bonded Fixed Partial Denture (RBFPD) has become a well-known treatment when the abutments are relatively intact or when preservation of tooth structure is needed [1]. These dentures can be preferable for young patient with big pulpal chambers. RBFPD was proposed as the patient was young and she had a wide pulp chamber and the patient consented with the treatment.The treatment plan was the same like previous case to achieve single insertion guide with a good resin template for RBFPD (Figure 1117). The patient had extracted #11 tooth’s root three months ago.The patient had a good medical record and oral hygiene.Intraoral examination showedthat tooth #11 was missing, and the adjacent teeth were still intact. The colour of the tooth was 3M3 vita 3D shade guide
