Preservación de alvéolos mediante fosfato tricálcico beta, con y sin membrana

The present study evaluated the results of the post-extraction socket preservation technique using Beta-Tricalcium Phosphate with and without the use of a non-resorbable membrane. A total of 18 teeth with indication of extraction and socket preservation were selected, with 10 alveoli being treated with Beta-Tricalcium Phosphate combined with a non-resorbable membrane, and the other 8 with Beta-Tricalcium Phosphate only. The width and height of each socket was evaluated using computed tomography, prior to the extraction, and 6 months after the surgery. At the time of performing the surgical technique for installing the implants, histological specimens were taken from the implant site in order to study the graft site 6 months after the dental extraction surgery and alveoli preservation.

The use of Beta-Tricalcium Phosphate, whether a membrane is used or not, maintained the alveolar height 6 months after the extraction, while the width of the alveolus only remained in the group without membrane. Histological results showed varying amounts of bone regeneration.
