Abstract

Surgery and periodontitis contribute to alveolar bone loss, resulting in increased tooth mobility. This is particularly evident post-tumor surgery, where larger bone defects are commonly encountered. Adequate bone mass is crucial for successful implant restoration in missing teeth. Conventional repair methods are unable to meet patients' functional and aesthetic expectations, while the loss of alveolar bone further compromises the initial stability of the implant. In the face of these challenges, Bone Ring Technique (BRT) demonstrates significant advantages. We conducted 3D reconstruction of the anterior aesthetic zone in a patient with maxillary bone defects following excision of maxillary odontogenic fibroma using BRT, resulting in satisfactory implant stability. This suggests the potential of BRT as a promising bone grafting technique.
骨环技术(BRT)在肿瘤术后前美学区三维重建中的应用
手术和牙周炎导致牙槽骨丢失,导致牙齿活动能力增加。这在肿瘤手术后尤其明显,因为通常会遇到较大的骨缺损。足够的骨量是成功种植体修复缺失牙齿的关键。传统的修复方法无法满足患者对功能和美观的期望,而牙槽骨的丢失进一步损害了种植体的初始稳定性。面对这些挑战,骨环技术(BRT)显示出显著的优势。我们对上颌牙源性纤维瘤切除术后的上颌骨缺损患者进行了前美学区三维重建,获得了满意的种植体稳定性。这表明BRT是一种很有前途的植骨技术。
