Summary

No ridge preservation technique has achieved to fully sustain the initial dimensions of the alveolar bone at the moment of tooth extraction. Lack of scientific evidence and prospective studies that use the alveolus as control site have been reported. The aim of this study was to clinically and imagenologically compare the variation of the alveolar ridge dimensions, using different alveolar ridge preservation techniques in a period of 6 to 8 weeks post tooth extraction. Ten (10) patients with orthodontic tooth extraction indication of four premolars were collected, using a split mouth design. An experimental side (two sockets) and the other side as control (two sockets). There were significant differences of bone resorption between the superior experimental group and the superior control group. 33, 3% of the experimental alveolus showed some kind of barrier membrane exposure, being Acellular Dermal Matrix (ADM) the most frequent (50%). The atraumatic extraction technique is the most simple and economic way of preserving the alveolar ridge. It was not possible to determine which technique is the most efficient to conserve la alveolar ridge dimensions.

KEY WORDS: technique, preservation; alveolar, tooth extraction.
