Abstract This study was performed to evaluate the effect of using electronic facebow on distribution of biting forces in mandibular fixed hybrid prosthesis through T-scan computerized occlusal analysis. Fourteen patients were selected from the out-patient clinic of Oral and Maxillofacial Prosthodontic Department, Faculty of Dentistry, Ain-Shams University, to participate in this study. Patients were thoroughly examined to reduce human variables and eliminate any factor that might affect the results of this study. All Patients were rehabilitated with mandibular fixed hybrid prosthesis. Standard clinical and laboratory techniques were followed for prosthesis construction for all patients. Patients divided into two equal groups, seven patients each: • group I: Patients were rehabilitated with mandibular fixed-hybrid prosthesis supported by six dental implants; the prosthesis was fabricated using electronic facebow (ARCUS Digma) for recording maxillary- mandibular relation. • group II: Patients were rehabilitated with mandibular fixed-hybrid prosthesis supported by six dental implants; the prosthesis was fabricated using the conventional jaw relation method and semi-adjustable articulator. T-Scan III, Computerized Occlusal Analysis System, was used to evaluate the distribution of biting forces. All data were recorded, collected, tabulated, and statistically analyzed. Results obtained from this study showed a statistically significant difference in comparing the distribution of biting forces between the two groups in favor of ARCUS Digma when compared to the conventional jaw relation technique. |
