Prevalencia de procedimientos regenerativos en alveolos post-extracción, HOSNAG 2019.

Abstract

Introduction: During extraction procedure, the bucal bone support is lost, stimulating bone resorption, there are regenerative techniques that help the body to repair its structure using different materials such as synthetic membranes, bone substitutes or platelet concentrates rich in growth factors. Objective: To determine the prevalence of regenerative procedures performed, after dental extractions, differentiating alveolar bone defects and what kind of materials are used for these procedures. Materials and methods: A cross-sectional, prospective and descriptive observational study was carried out where out of 52 patients, 108 post-extraction alveoli were analyzed, the cause and tooth extracted were registered, the type of post-extraction bone defect was also verified from the walls and it was classified according to the new classification of alveolar dehiscences of Yang Y, et al.(10) and the type of grafting material used in each patient was specified if regenerative procedure was performed. Results: Of 108 alveoli analyzed, 25 alveoli (23.15%) were regenerated with the alveolar crestal preservation technique, class I defects (81.48%) were found, II (5,55%) and III (6.48%), also the most commonly used regenerative material is the clot-shaped PRF followed by bone substitutes with collagen membrane; a higher prevalence of retained third molars is observed in patients between 13 and 20 years old and that the main causes of teeth extraction are the retention of third molars, dental fractures, root remains and indications for orthodontics. Conclusion: alveolar defects increase the difficulty, time and cost of treatment for the rehabilitation of a patient with edentulism; There is a low prevalence of post-extraction regenerative procedures and there is a wide variety of materials that can be used to preserve post-extraction alveolar bone dimensions.
