The aim of the present study was to present the results of patients followed for at least 3 years who underwent horizontal distraction osteogenesis DO and a final implant prosthesis.
A total of 13 sites in 12 patients (three men, nine women; mean age 45.4 years, range 21-63 years) who presented with severe horizontal atrophy of a partially edentulous maxilla or mandible were treated using horizontal DO. The horizontal distraction device was set on the transport bone which was osteotomized as bone splitting method and fixed to the segment using microscrews.
The median of latency period was 9 days (range: 7-17); the median of amount of device activation was 5.6 mm (range: 4.4-9.6); the median of distraction period was 14 days (range: 8-24); and the median of consolidation period, from the end of activation until implant placement, was 13 weeks (range: 11-20). The median of actual gain in bone width at the end of the consolidation period was 3.6 mm (range: 1.1-5.6). A total of 35 implants were inserted in the augmented area with primary implant stability. The median of follow-up from the start of prosthetic loading was 5.4 years. Consequently, the implant survival and success rates were 100% and 94.2%, respectively.
This article reports the long-term results of horizontal alveolar DO using a mesh device for patients with an atrophic alveolar region. Our results confirm that this technique is a predictable and effective regenerative procedure for implant preprosthetic treatment in patients with severe horizontal atrophy of the alveolar ridge.
本研究旨在报告至少接受 3 年随访的患者接受水平牵引成骨术（DO）和最终植入义齿修复的结果。
12 例患者（3 例男性，9 例女性；平均年龄 45.4 岁，范围 21-63 岁）共 13 个部位因部分无牙上颌或下颌严重水平萎缩而接受水平 DO 治疗。水平牵引装置设置在经骨劈开法截骨的运输骨上，并使用微螺钉固定到节段上。
潜伏期的中位数为 9 天（范围：7-17）；装置激活量的中位数为 5.6 毫米（范围：4.4-9.6）；牵引期的中位数为 14 天（范围：8-24）；从激活结束到植入物放置的巩固期的中位数为 13 周（范围：11-20）。巩固期末实际获得的骨宽度中位数为 3.6 毫米（范围：1.1-5.6）。在增强区域共植入 35 枚种植体，具有初级种植体稳定性。从开始修复负重起的中位随访时间为 5.4 年。因此，种植体的存活率和成功率分别为 100%和 94.2%。
本文报告了使用网孔装置对萎缩牙槽嵴患者进行水平牙槽骨 DO 的长期结果。我们的结果证实，对于牙槽嵴严重水平萎缩的患者，该技术是一种可预测且有效的种植前再生程序。
