| Abstract | ||||
| Purpose: The goal of this study was to evaluate and compare stress transmitted to abutment tooth of distal extension removable partial denture retained with L-bar clasp – In vitro study of different origination of bar clasp to abutment tooth.Materials and Methods: Partially edentulous acrylic resin mandibular model of bilateral distal extension ridge with remaining teeth from first premolar to first premolar will be fabricated and duplicated to fifteen models. Poly vinyl silicon impression material will be packed to simulate mucosa covering distal extension ridge. Removable partial denture frame work will be fabricated with L-bar clasp placed on distal abutment, lingual bar major connector, mish-work retentive minor connector and cinglum rest on canine that act as indirect retainer. Results: Theresults of mean µ strain comparison between studied groups at buccal, distal and lingual in bilateral loading. There was a statistically significant difference among the studied groups with higher mean µ strain at group 3 followed by group 1 then group 2. | ||||
