Biodegradable ceramic implants in bone. Electron and light microscopic analysis.

Abstract The main purpose of a biodegradable ceramic implant is to fill a bone space as well as to eliminate the need for a metallic implant. Although the biodegradable ceramic does stimulate bone formation and does disappear from the implanted site, it does not have the same initial strength as a metal or nondegradable ceramic implant. When completely replaced by bone, however, it should prove superior to the latter two. Additional studies comparing degradable ceramic with various other types of ceramic material and with unfilled bone defects are in progress.

Reaction of bone to tricalcium phosphate ceramic pellets

Abstract This study indicates that tricalcium phosphate is well accepted by the tissue and may actually contribute mineral salts for the formation of bone at the site as the ceramic is broken down into granules.

Controlled cryotherapy in the treatment of inflammatory papillary hyperplasia

Abstract Cryosurgery is an effective, painless method for the removal of inflammatory papillary hyperplasia. It requires no local anesthetic, and there is no offensive odor or postoperative or operative bleeding. The method is attended by little postoperative discomfort. Total healing occurs from 3 to 5 weeks postoperatively. The palatal mucosa has a normal appearance and is soft and nontender. A method employing a Freon-cooled probe has been used effectively on twelve patients with inflammatory papillary hyperplasia.
