• Resumen

  • Introduction: The biological processes that take place following dental extractions cause defects in the soft and hard tissues of the jaw, which hinder rehabilitation techniques with implants. Alveolar preservation procedures have been proposed to decrease these dimensional changes. Although autogenous bone is considered the material with the best properties, it also leads to an increase in patient morbidity. Therefore, the tooth itself is considered as an alternative. The objectives of this review were to analyse the dimensional changes in alveolar ridge height/width after alveolar preservation procedures using particulate dentin, as well as possible intraoperative and postoperative complications, new bone formation and re-entry time in the grafted area.

    Materials and method: A review of the relevant literature in the PubMed and MEDLINE databases was carried out, identifying studies evaluating alveolar preservation procedures with particulate dentin in human patients with recorded follow-up.

    Results: A total of 12 studies were included in the systematic analysis. The dimensional changes, after grafting with particulate dentin, were comparable to those of other biomaterials and fewer than in the control groups. The occurrence of complications was low. New bone formation and re-entry time were similar to other biomaterials.
