摘要

水平全无牙萎缩嵴的处理是牙种植学中的一个常见问题。本案例报告描述了一种可供选择的改良两阶段预裂技术。患者被转诊接受种植体支持的无牙下颌骨康复治疗。CBCT扫描显示平均可用骨宽度约为3毫米。在第一阶段,使用压电手术装置进行了四次线性皮质切除术。在4周后的第二个手术阶段,进行了骨扩张,并在椎间孔间区域放置了四个植入物。愈合过程波澜不惊。未观察到颊壁骨折和神经损伤。术后CBCT扫描显示平均骨宽增加约3.7 mm。第二次手术后6个月,植入物被揭开,1个月后,植入了固定的临时螺钉固定假体。这种方法可以作为一种重建技术,避免使用移植物,并通过尽可能多地利用患者的天然骨来减少治疗时间、可能的并发症、术后发病率和成本。考虑到病例报告的局限性,需要进行随机对照临床试验来确认结果并验证这项技术。

The Curved Presplitting Technique in a Totally Edentulous Atrophic Mandible: A Surgical Case Report.

The management of horizontally fully edentulous atrophic ridges is a common problem in dental implantology. This case report describes an alternative modified two-stage presplitting technique. The patient was referred for an implant-supported rehabilitation of their edentulous mandible. CBCT scans showed a mean available bone width of about 3 mm. At the first stage, four linear corticotomies were performed using a piezoelectric surgical device. At the second surgical stage 4 weeks later, bone expansion was performed, and four implants were placed in the interforaminal area. The healing process was uneventful. No fractures of the buccal wall and no neurologic lesions were observed. Postoperative CBCT scans showed a mean bone width gain of about 3.7 mm. Implants were uncovered 6 months after the second surgery, and 1 month later, a fixed provisional screw-retained prosthesis was delivered. This approach could be used as a reconstructive technique that avoids using grafts and reduces treatment times, possible complications, postsurgical morbidity, and costs by exploiting the patient's native bone as much as possible. Considering the limitations of a case report, randomized controlled clinical trials are needed to confirm the results and validate this technique.

期刊介绍: The International Journal of Periodontics & Restorative Dentistry will publish manuscripts concerned with all aspects of clinical periodontology, restorative dentistry, and implantology. This includes pertinent research as well as clinical methodology (their interdependence and relationship should be addressed where applicable); proceedings of relevant symposia or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published or submitted for publication elsewhere.
