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. INTRODUCTION 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 also be preferable for young patient with big pulpal chambers. In addition, the RBFPDs have been attractive for patients and dentists because of the minimal loss of tooth structure during tooth preparation. Anaesthesia can be avoided in some patients’ treatment. RBFPDs also enable vitality test and/or endodontic treatment of the abutments after its insertion [2,3]. Resin bonded fixed partial denture is considered as the replacement of conventional fixed partial denture (FPD) to keep the abutment intact and not prepared into crown. This design is conservative for replacement of single tooth [1,4]. Minimally invasive RBFPD is not meant to reduce unnecessary tooth structure but still having a good mechanical retention for long term success of the restoration. RBFDP was indicated in these cases for replacement of missing anterior tooth in young people, the missing span was too small, and the patients like to use fixed dentures with minimal cost. The mechanical retention of retainer resin bonded by tooth micropreparation is crucial; however specific tooth preparation, good luting cement will increase bonding to metal and tooth structure so the failure will be minimized [2,5,6]. In order to achieve precision intraoral preparation, Okada and Inoue (2008) stated that the ideal preparation isn’t www.adum.edu.my Ann Dent UM 2020, 27:22-27 DoI: 10.22452/adum.vol27no4 Case Report 1 Department of Prosthodontics, Faculty of Dentistry, Universitas Sumatera Utara, Medan, Indonesia *Correspondence: chihargo89@gmail.com
