[The principles of designing stump pin inserts in pathological tooth abrasion].
A total of 278 patients aged 40 to 67 with pathological abrasion of hard dental tissues were treated. Decreased occlusion height was diagnosed in 152 (54.67%) of these. In 146 patients abutment teeth under permanent dentures were fixed with cast stump pin insertions. Complications occurred in 9.6% cases: perforation of the wall of the root canal (1.14%), failure of cementing (3.98%), fracture of the root (1.14%), breaking of a fragment of the root at the neck of the tooth (2.84%), and inflammations of the marginal periodontium (0.57%). In order to prevent these complications and improve the fixation of cast stump pin insertion, we used our modifications of cast stump pin insertions (n = 394) for anterior and lateral teeth. The incidence of complications decreased more than 5 times. Follow-up of 2 to 8 years showed 1.78% of complications.
