Effects of pin hole position on stress distributions and interpulpal temperatures in horizontal nonparallel pin restorations.
Biomechanical evaluation was made of horizontal nonparallel pin position effects on stresses of tooth structure and interpulpal temperatures with a stress analysis and heat conductive analysis, following finite element methods. The results were that it is adequate to use geometry to decide horizontal pin position in a routine clinic.
