Coágulo sanguíneo: uma opção NÃO viável para a preservação alveolar

Abstract

The loss of dental elements leads to an intense remodeling of the alveolar process, resulting in important dimensional changes, which often make it difficult to install dental implants. Considering this, the objective of the present study was to evaluate the changes in height and thickness that occurred in dental alveoli after extraction. For this, 10 patients were evaluated and submitted to extraction of dental elements and followed up in the postoperative period in which there was natural healing. Cone beam computed tomography were obtained preoperatively and 3 months postoperatively and were used as a basis for assessing loss of height and thickness that occurred. Pearson correlation test with a significance level of 5% was used to assess dimensional changes. The results showed that vertical loss (average of 2.99 mm) was greater than the horizontal loss (average of 2.52 mm). The statistical analysis pointed out the existence of a very good and significant correlation between these bone losses and also revealed that the higher the loss of height, the greater the loss of thickness. In 8 of 10 patients in the sample, some grafting was necessary prior to the installation of the implants, thus increasing morbidity and time of treatment. Considering this, it was concluded that the clot was not a viable alternative for alveolar preservation aiming posterior installation of dental implants.
