Sažetak
Loss of a large number of teeth in the lateral segment of the maxilla, either on one side or both, represents a challenging therapeutic procedure. Today the demands of the patient have increased with regard to fixed prosthetic treatment for lateral segments of edentia.
Although lateral edentia can more easily be solved by a partial prosthesis or a cantilever bridge, dental implantology is now one of the solutions in the daily practice of the dentist. One of the most frequent problems in solving distal edentia of the maxilla by the use of dental implants is connected with the anatomic relations between the maxillary sinus and alveolar prolongation of the maxilla, i.e. the socalled deep recess of the maxillary sinus, or even the result of severe atrophy of the alveolar prolongation. Such situations do not facilitate insertion and good stabilisation of dental implants, and thus they narrow indications for fixed prosthetic work. With the development of dental implantology during the 1980s, a possible solution for this problem arose, by an operation to raise the floor of the sinus, which today is known as “sinuslifting”. Prospectively, operation techniques are diverse, as are also the different materials used in these operations. Sinuslifting is in fact a reconstructive surgical procedure, which with osteal implants or osteal restorations achieves the formation of bone on the floor of the maxillary sinus in the alveolar recess, where the dental implant will later be inserted. Today's technique is briefly described as the opening of the lateral osteal wall of the maxillary sinus, and this osseous fragment is twisted towards the interior of the sinus cavity and the resulting area (caudal third) filled with augmentation material. If there is sufficient height of the bone in the area of the floor of the sinus (4-5 mm) the implant can be carried out at the same time as sinuslifting, to ensure safe primary stabilisation of the dental implant.
We present the case of a 33-year old patient with sinuslifting in the right segment of the maxilla, as preparation for dental implant. The patient already has osseointegrated implants in area 46 and 37.
