ABSTRACT
Limited bone height restricts the use of long dental implants, so short implants may be selected in these situations. Recent reports on clinical results with short implants have been negative, however, and have suggested that indications for the use of these implants are limited. To verify these findings, a multicenter study of short ITI implants was carried out. In a 6-year period 253 short implants with a length of 6 mm were placed into 126 patients, who were followed up from 1 to 7 years. Altogether 7 implants were removed; 6 of these were located in the maxilla and 1 in the mandible. The quality of survival was comparable with the clinical results of longer implants from the same implant system. Although the clinical results of these short implants were favorable, it is recommended that they be used in combination with longer implants, especially when used in the less dense bone that is often seen in the maxilla.

The edentulous mandible provides a frequent indication for oral implants. In many cases implants are placed in the interforaminal region to support fixed prostheses or give retention to removable overdentures. One of the hazards of this seemingly safe surgical area is hemorrhage of the floor of the mouth. In this article, two cases of this life-threatening complication are reported.

The procedure described in this article is based on the surgical subtotal luxation of a tooth-containing alveolar segment and allows the repositioning of single teeth while almost regularly safeguarding tooth vitality. This procedure has proven particularly effective in the treatment of maxillary anteriors, canines and premolars. For patients preferring surgical correction to long-term orthodontic treatment this limited operative intervention allows safe orthodontic alignment. To date, relapses have not been observed in the cases treated. Stable immobilization of up to six weeks postoperatively is achieved by splinting.
