[Results after insertion of apical titanium cones in apicoectomy].

In a post-treatment study 50 apicoectomized teeth in 34 patients being treated with apical titanium cones between 1988 and 1990 were registered. After a mean postoperative observation period of 15.3 months, 42 teeth were still in situ and subjected to clinical and radiographical evaluations. Their mobility was measured by the periotest method. A resulting 84% success rate demonstrates the technique to be suitable to safeguard a prolonged lifetime of severe damaged teeth by use of conical pins which guarantee a perfect closing at neoapex.
