Transdental Implants in the Case of Wider Indications for Apicotomy of the Median Upper Incisor

The principles of classic mechanical retention are still applied today in modern medicine and dental medicine. Examples of this are transdental implants, modified from needle implants, i.e. triplants. The concept of their application originates from Scialo-ma in 1962, although in the literature they were mentioned even earlier. Because of the wide selection of indications and biocompatibility transdental implants have their place today in dental medicine. The case of a fourteen year-old girl is presented, in whom therapy with a transdental endoosseous implant was applied, because of a recurrence of an ostitic peri-apical process on the median left upper incisor following repeated apicotomy. The clinical and radi-ographic finding showed considerable loss of bone and dental tissue, which had resulted in the movement of the tooth in all directions. Because of the indications the therapy chosen ensured stability and lengthened the longitudinal axis of the tooth. Stainless steel wire, 0.9 mm in diameter, was used for the transdental implant, driven into the bone with the control of the naked eye. The case was monitored and documented during the period from 1990 until today, and proves the justification of the therapy. This example shows how a " lost tooth " does not always have to be that. The Tooth in the Maxillary Sinus as a Summary All textbooks on oral surgery mention the pushing of the tooth root or the whole tooth into the max-illary sinus as one of the possible complications during tooth extraction. While the first complication is relatively frequent and oral surgeons come across it almost every day, pushing of the whole tooth into the maxillary sinus is an uncommon complication. Two cases of the wisdom tooth in the maxillary sinus were admitted last year for treatment in the Clinical Department of Oral Surgery. Both cases were complications which occurred during alveotomy of upper impacted wisdom teeth. In both cases the teeth
