Abstract

Preclinical session is one way of training dental undergraduates to prepare teeth for restorations. The aims of the study were to evaluate students’ perception and satisfactory level in preparing tooth for porcelain fused to metal crown in preclinical fixed prosthodontics sessions. A total of 104 fourth year dental undergraduates students participated in this study. Lecture consisted of the diagrams of step-by-step procedure in preparing porcelain fused to metal crown on tooth 24. Video demonstration was also conducted. After they were satisfied with the preparation, they were asked to answer a series of multiple choice questions on their performance. Only 92 students completed the questionnaire. Majority of the students taught that their occlusal and axial reductions were about right. As for the margin, 50 students claimed that the margin was located on gingival margin while 88 students said that they prepared shoulder margin buccally and 4 students created chamfer margin buccally. Seventy four out of 92 students were slightly satisfied with their crown preparations. Twenty five students said that they were very competent and confident in doing crown preparation to patients. Almost all fourth year dental students could perform porcelain-fused-to-metal crown preparation with confidence. As conclusion, exposure to our teaching methods and aids appears to help them in preparing these tasks.

Abstract

Fabrication of prostheses must be planned and designed to fit harmoniously with the complexity of the neuromuscularsystem of the patient, the temporomandibular joints and supporting structures of the teeth. Any occlusal interference fromthe prostheses would invade the systems and caused various problems to the patient. The aim of this study was to evaluatethe occlusion of 3-unit conventional bridges prior to cementation. All bridges that scheduled for cementation was noted.Before the occlusal examination was performed, the retainers were examined to ensure good marginal fit and haveadequate interproximal contact with adjacent teeth. Occlusal examination was performed using articulating foil with thethickness of 8µm, Miller’s forceps and thickness gauge. From 33 bridges identified, 93.9% were qualified for occlusalexamination. Most of the retainers and pontics showed multiple high spots. From 62 retainers and 31 pontics, 213occlusal contacts were obtained, with 25.8% on cuspal inclinations, 24.4% presented with high spots on marginal ridgesand 11.7% on cuspal tips. The thickness of the high spots ranges from 0.5-3.6mm. High occlusion could be resulted fromvarious factors such as inadequate tooth preparation and lack on the usage of semiadjustable articulator. Occlusalexamination has to be performed prior to bridge cementation to ensure comfort during functioning and health of the hardand soft tissues.
