RESUMO
BACKGROUND: Guided Bone Regeneration (GBR) is a versatile technique employed not only to correct pre-implant alveolar bone defects but also to facilitate bone defect correction during simultaneous implant placement. The effectiveness of GBR varies significantly among different protocols, as reported in the literature. This study specifically aimed to radiologically evaluate the horizontal bone gain obtained using a GBR procedure combining a particulate allograft, platelet-rich fibrin, resorbable collagen membrane, and screw tents. MATERIALS AND METHODS: A total of 42 patients with an insufficient alveolar bone width for dental implant placement were treated with a GBR technique using a mixture of particulate allograft (demineralised freeze-dried bone allograft 300-500 and 500-1000 µm), advanced platelet-rich fibrin (A-PRF), resorbable collagen membranes and screws tents (1.2 mm in diameter). Over the course of the study, a total of 63 GBR procedures were performed on these patients. Bone gains were measured by cone-beam computed tomography at 9.1 ± 2.0 months post-operative. RESULTS: A significant mean increase (P < 0.001) of 3.2 ± 0.9 mm at the sites of the greatest bone defect was observed. This improvement was consistent across various locations, including both maxillary and mandibular regions, and in cases of terminal and embedded edentulism, without any post-operative complications during the entire post-operative follow-up. All patients benefited from implant placement following the bone augmentation protocol. CONCLUSION: GBR combining particulate allografts, A-PRF, collagen membranes, and screw tents achieves reliable, predictable, and reproducible clinical gains that allow for future implant placement.
RESUMO
Wisdom tooth extraction is a common procedure in dentistry and stomatology. Subcutaneous emphysema is a rare postoperative complication and commonly remains localized. However, it may spread to the mediastinum, endangering the life of the patient. This present paper presents a case study of pneumomediastinum after wisdom tooth extraction without the use of a compressed air turbine and reviews the cases of subcutaneous emphysema after third molar extraction published in the literature since 2010. The aim of this work is to inform preventive measures, pathophysiological processes, and management related to this complication.
RESUMO
Mandibular swellings are common, but a hernia of the masseter muscle is a rare condition. This case report describes the case of a young patient presenting a masseter muscle hernia and discusses the management of this condition.
