Alveolar Reconstruction With Splitting Osteotomy and Microfixation of Implants


PMID: 9197095

This report describes a surgical technique for reconstruction of the buccolingually reduced alveolar process. The technique involves the preparation of an artificial socket with immediate implant placement, which reduces total treatment time compared with two-stage procedures. Alveolar preparation comprises lamellar cortical splitting of the alveolus, interlamellar implant placement, and primary stabilization based on a microfixation technique. It was used for a wide range of indications involving single and multiple alveoli related to the partially dentate and the edentulous alveolar process. The results of 24 Branemark standard implants and 97 ITI implants with 44 consecutively treated patients have been reviewed with a mean observation time of 34.3 months (range 6 to 68 months). The main indicator for alveolar reconstruction was the narrow anterior maxillary arch. The 5-year cumulated success rate was 86.2%. Twelve imp lants failed during the observation period. The mean marginal bone loss was 1.7 mm (range 0 to 7.5 mm). There was a low infection rate compared with membrane-based GTR techniques. Treatment costs were low as a result of shorter treatment time.
