Relleno de defecto óseo postquirúrgico con hidroxiapatita: reporte de un caso

Abstract

Odontogenic cysts are characterized by a cavity lined by epithelium and a capsule containing connective tissue, being periapical cyst the most common one due to the chronic infection and necrosis of the pulp organ. These type of lesions causes irreversible damage to the bone tissue, which healing process is slow and not always leads to complete healing of the bone defect. Hydroxyapatite is the major component of bone and teeth of all vertebrates, that is why biomaterials based on hydroxyapatite does not cause significant immune response when implanted in the body. The aim of this paper is to demonstrate the effectiveness of hydroxyapatite (Apafill-G), as an osteoconductive and promoter of bone defects regeneration material. The case of a 32 years old male patient is reported, who at routine radiographic examination presented a jaw injury compatible with periapical cyst, associated with right upper central incisor, which was treated surgically, sealing the defect with Apafill-G (0,4mm-0,6mm), posterior suture with tissue adhesive (Tisuacryl®), and clinical and radiographic postoperative controls. Excellent results were obtained in the postoperative evaluation of the patient treated, proving the high biofunctionability and biocompatibility of the biomaterials used.
