To investigate the results of edentulous patients with severely resorbed mandibles who were treated with a modified tent pole procedure.
Twenty-two edentulous patients (3 men, 19 women; mean age, 62 yr; range, 51 to 72 yr) with a history of conservative prosthodontic treatment failures were included this study. Using a transcutaneous submental approach, 4 endosseous dental implants were placed in the anterior mandible of each patient and covered with autogenous bone grafts harvested from the posterior iliac crest without the addition of platelet-rich plasma. Follow-up ranged from 3 to 9 years.
The postoperative course of the patients was uneventful, without any surgical infections. At 3 months postoperatively, the density of the grafted bone appeared to closely resemble that of the surrounding alveolar bone on panoramic radiographs. The average alveolar augmentation was 6.3 mm (standard deviation, 1.59 mm; range, 4 to 10 mm) and long-term follow-up showed no bone resorption around the endosseous implants.
The modified tent pole technique without the addition of platelet-rich plasma is a safe and effective method to reconstruct the severely resorbed mandible.
探讨采用改良帐篷杆技术治疗下颌骨严重吸收的无牙颌患者的效果。
本研究纳入了22例无牙颌患者（3例男性，19例女性；平均年龄62岁；范围51至72岁），这些患者均有保守性修复治疗失败史。采用经皮颏下入路，在每位患者的下颌前部植入4枚骨内牙种植体，并用取自髂后嵴的自体骨移植覆盖，未添加富血小板血浆。随访时间为3至9年。
患者术后过程顺利，无任何手术感染。术后3个月时，全景X线片显示移植骨的密度与周围牙槽骨的密度非常相似。平均牙槽嵴增高6.3毫米（标准差1.59毫米；范围4至10毫米），长期随访显示骨内种植体周围无骨吸收。
不添加富血小板血浆的改良帐篷杆技术是重建严重吸收下颌骨的一种安全有效的方法。
