Respuesta biológica entre una hidroxiapatita y un betafosfato tricalcico en la regeneración de tejido óseo

Abstract

When teeth are extracted maxillary tissue and jaw bone is remodeled to form the residual alveolar ridge, which tends to be reabsorbed gradually taking different forms. This pheno-menon can be modified when placed in bone that contributes to the new formation and maintenance of bone morphology, thereby facilitating prosthetic treatment. The aim of this paper is to present a surgical technique combining internal and external filled the alveoli, allowing conventional prosthesis subsequently rehabilitate or metal implants. We present 5 patients who underwent dental extractions, the padding inside the socket with absorbable material (Biograft-G ®) and the outer table of the alveolar bone ridge regularized with the stable product Apafill-G ®. At that time placed a kind acrylic prosthesis immediately. Pa-tients were evaluated clinically and radiographically at 7 days, 1 month and 6 months. The results showed that both materials filled with proper bone regeneration achieved without peel granules, adjusting prosthesis and absence of sub denture stomatitis, edema or erythe-ma adverse events. We obtained a well-formed rim, avoiding the mandibular or maxillary atrophy. We achieved a strong external wall to receive acrylic prosthesis, while the inner filling resorbable facilitated the possibility of metallic implants. We conclude that this is a new surgical alternative to prevent the atrophy of the alveolar ridge without interfering infuture prosthetic rehabilitation.
