Abstract

Purpose: The aim of the present study is to compare the stresses induces on the splinted abutments by two different reciprocation designs in conjunction with extracoronal semi-precision attachments retained removable partial denture (RPD) using strain gauge analysis. Material and methods: For this study, two RPD designs were made A, and B. representing maxillary bilateral distal extension edentulous area. The two abutments, canine and first bicuspid was fixed splinted on both sides with porcelain facing crowns. For design (A) an extra coronal attachment with integrated interlock was used at the distal aspect of the splinted first bicuspid and canine. For design (B) a parallel interlock extra coronal attachment was used with a conventional lingual bracing arm. A strain gauge was used for this study to measure the micro-strain induced on the apical and lateral sides of the canine and first-bicuspid abutments. Results: SPSS software program was used in the statistical analysis of the results. The results revealed that maximum stresses induced at the apex of the canine and firstbicuspid abutments were in case of design (B). While no significant difference between the two designs when the lateral load was applied Conclusion: A more favorable stress applied on the canine and bicuspids obtained with integrated interlock attachment.
