In order to determine the clinical significance of mucosalplasty of edentulous ridges to improve pontic adaptation, the first step was to make a cut in the mucous membrane of the edentulous ridges of dogs using a surgical scalpel, diamond point used in gingivoplasty, and an electrode tip, to observe the healing process and degree of tissue damage from a histopathologic and oralbiomicroscopic standpoint.
The results were as follows;
1) Immediate postoperative findings after the use of a surgical scalpel showed minute tissue damage, and oralbiomicroscopy after 21 days showed keratinization of the epithelial cells, and a return to normal histological structure was observed after 28 days.
2) Effect upon the wound surface immediately following the use of the diamond point showed localized degeneration, but did not appear to affect the healing process and showed the same type of healing process as those under the use of the surgical scalpel.
3) Dentoelectrosurgery caused degenereation, necrosis, and lack of normal blood supply, which resulted in a delay of the healing process. However, normal histological tissue were observed 28 days later.
4) Although the healing duration were different in the three methods, they all resulted in successful mucosalplasty of the edentulous ridge for the improvement of pontic adaptation. Findings also showed that the special features of each method should be utilized wisely in clinical application.
