Effect of splinting on abutment tooth movement.
The effect of splinting on abutment tooth movement was investigated in an in vitro study. An acrylic resin mandibular model with missing molars and a removable partial denture framework were constructed. The roots of the premolars and edentulous ridges were coated with silicone rubber. A modified Ney surveyor was used for load application, and abutment tooth movement measurements were made with a macroperiodontometer. Four conditions were tested by applying unilateral loadings: 1. Single abutments of both sides 2. Load side double abutment 3. Nonload side double abutment 4. Double abutments of both sides The results showed that a significant decrease in the magnitude of movement resulted when the abutment teeth were splinted.
