What should be done to prevent the distal abutment problem (mobility/resorption) caused by the precision-attachment RPD on tooth #21?
Show answer and explanation
Correct answer: A. Splint tooth #21 to the adjacent tooth (#22) to distribute forces
Splinting the overloaded abutment to an adjacent tooth distributes occlusal/lever forces over more roots, reducing mobility and protecting the periodontium.Other options: Increasing rigidity or load worsens torque; removing rests destabilizes the prosthesis.Key exam takeaway: Splinting weakened abutments distributes load and limits further mobility and bone loss.
