Distraction osteogenesis (DO) gives an opportunity to provide needed volume of bone and soft tissues for the normal function and rehabilitation of the masticatory apparatus.
In the poster is shown a case of patient treated with DO of the maxillary alveolar crest with subsequent insertion of dental implants and fixed bridge prosthesis.

Aim: To estimate the opportunity DO to be used in daily out-patient practice as well as a method whit good prognosis to provide the needed volume of tissues for the rehabilitation of the masticatory apparatus.

Materials and methods: 55 y.o.w. with alveolar crest atrophy in the region of 25 – 28 teeth needs rehabilitation with dental implants. Teeth have being extracted years ago. Attempts are made for sinus lift and vertical bone-block plastic. We took a decision for vertical DO of the alveolar crest with intraoral distractor with subsequent inserting of dental implants and bridge prosthesis.

Results and discussion: after an osteotomy, placing the distractor and waiting for a week, in a period of 10 days is achieved needed distraction of the bony fragment. After five months period of bone consolidation the distractor is removed and two dental implants are inserted. After osteointegration period of three months bridge prosthesis was made.

Conclusions: DO is applicable as well in out-patient practice of doctors with surgical skills. It is a promising procedure and despite of high traumatic level can be used in motivated patients to provided needed volume of hard and soft tissues.
