Abstract:

Purpose: The aim of this study was to evaluate the stress applied on abutments and alveolar ridge using a new unilateral semiprecision attachment with different number of splinted abutments in unilateral distal extension cases. Methods: A fabricated acrylic maxillary casts simulating a unilateral distal extension (Kennedy class II) case was used. Abutments (canine, first and second premolar) on one side were prepared to receive two/three splinted crowns with the unilateral attachments. The strain gauges were installed around the abutments and on the edentulous ridge. A loading device was used to produce standardized static load on the molars area and around the splinted abutments. Results: Two splinted abutments showed statically higher significant mean strain for the lingual and distal surfaces compared to three splinted abutments. While three splinted abutments showed statically insignificant mean strain compared to two splinted abutments for the residual ridge. Conclusion: Increase in number of splinted abutment in extracoronal unilateral attachment decrease the stresses applied on distal abutment in unilateral distal extension cases. The difference in the induced stresses recorded at distal extension area was not statically significant.
