Root resection of 150 maxillary and mandibular molars
Abstracts apicoectomy. S. Trippler, P. Tetsch and H. J. Schmitt, Mainz
214 apicoectomized teeth in 173 patients were treated with apical titanium cones at the outpatient clinic for dental surgery of the University of Mainz between 1981 and 1985. A statistical evaluation of the patient documents involved the clinical and radiographic pre-treatment findings, the indication for apicoectomy and the complication rate. It was completed by a follow-up on 106 resected teeth after a mean observation period of 26 months. Based on the clinical examination data as well as on the evaluation of recent radiographs, the result was a success rate of more than 90% for this treatment method.
Root resection of 150 maxillary and mandibular molars. M. Franz, K. Bethke and J. Bier, Berlin
Apicoectomies with and without surgical root tilling were performed on 5t2 maxillary and mandibular molars in 438 patients. The indication for apicoectomy was kept wide. A preoperative and postoperative retrospective evaluation of the findings on 133 patients had to be performed at an average of 1 year after surgery. 150 molars with a total of 369 resected roots were evaluated. The apicoectomies of 110 molars (73%) were rated as successes and of 40 molars (27%) as failures.
TRANSDENTAL FIXATION
Indication and prognosis of the ISO titanium conesystem. B. Hoffmeister and U. Lindemann, Kiel
The silver cones after Rehrmann or the PD systems used up to now should be replaced by bio-inert titanium cones for apicoectomies with intraoperative root filling. The system introduced by Messing in 1980 has been used in our clinic since 1984. The indications for the application of the titanium cones and the surgical technique are presented. 50 out of 74 apicoectomized teeth with titanium cones were re-evaluated. The procedure selected is another step ahead in improving the prognosis for apicoectomy.
Apicoectomy with standardized intraoperative AI203 ceramic cone filling. First results of a prospective study of 100 maxillary anterior teeth. S. J~nicke and P. Tetsch, Mainz
A method of apicoectomy is presented with a two-part root filling with an apically-placed cone made of aluminium oxide ceramic. 108 maxillary front teeth were treated with this method. The points placed showed an exact tight apical seal. A prospective study over a period of 6 months gave evidence of a recognizable decrease in the mobility of the apicoectomized teeth, fast regeneration of the osseous defect as well as both subjectively and objectively minimal stress to the patient.
Indications and results in surgical tooth preservation by means of transdental fixation. F. H~uBler and K. H. Maier, Kempten (AIIgNu)
The results of transdental fixation using titanium alloy screws are reported. Out of the 16 cases treated over the past 2~/2 years, there was one failure up to now. In all the other cases, the otherwise inevitable extraction of teeth could be avoided at least for the time being.
Transfixation of teeth with titanium plasma-coated pins in animal experiments. V. Strunz, U. Gross and A. Kitsch, Berlin
Transdental fixation as a "closed implantation procedure" provides an opportunity for material testing under physiological masticatory loading. An attachment apparatus similar to Sharpey's fibers could not be demonstrated around the titanium plasma-sprayed pins. In some cases, however, an ankylotic contact between the implant material and the new bone could be observed.
Results of transdental stabilization of loosened teeth and fractured roots. H. Bechtold, H.-G. Bull and F. Schubert, DOsseldorf
During the past 6 years, transdental fixation was performed in 73 cares and endodontic compression screw stabilization with simultaneous transdental fixation in 21 cases. The results of reg-

utar clinical and radiological follow-up showed good function in 83% of the transdentally fixed teeth during a mean observation period of 2~/2 years. 17 of the 21 teeth with root fractures treated with endodontic compression screws and at the same time transdental fixation were followed-up for a mean observation period of 3 years; good function was observed in 12 of these teeth.
First results with bicylindrical titanium cone implants for transdental fixation. H. Rixecker and W. Schilli, Freiburg/ Breisgau
The titanium cone after Schilli and associates for sealing apicoectomized roots has been further developed, the result being a flexible, bicylindrical titanium cone for transdental fixation. Bending the biocampatible titanium cones permits the transfixation of even those teeth whose axes are at an angle to that of the alveolar process. The clinical experience gathered with over 100 titanium cones implanted to date indicates good bone regeneration in the apical portion of the cones, thus safeguarding stability.
Stabilizing 'single-rooted teeth by means of transfixation pins. B. Schramm-Scherer, P. Tetsch, St. Trippier and U. BrOderle, Mainz
The results of a post-treatment evaluation of 100 teeth treated in the outpatient department for dental surgery of the University of Mainz between 1983 and 1985 with transdental fixation are presented. The statistical evaluation of the patients' documents includes the preoperative clinical and radiological findings, the indication for transdental fixation and complications in the application of the systems. A clinical and radiological follow-up examination after a mean postoperative observation period of 16 months completes the study. The analysis of these findings showed a 86% success rate.
