Lack of sufficient alveolar bone height or width is one of the most frequent problems in the dental rehabilitation of the edentulous patient.
A prospective study to evaluate the efficacy of an endosseous alveolar distractor (LEADTM) in managing residual alveolar ridge resorption was carried out. The complications related to the surgical procedure and the quantitative changes in the regenerate over a 6 month period following distraction were studied in 13 cases with alveolar ridge atrophy.
Desired ridge augmentation was achieved in 11 cases. In 2 cases the distraction failed. Some unusual complications were encountered.
The LEAD™ alveolar distractor produces consistent augmentation of the alveolar bone but is confronted with stability issues.
在无牙患者的牙修复中,牙槽骨高度或宽度不足是最常见的问题之一。
开展一项前瞻性研究,以评估骨内牙槽牵张器(LEADTM)在处理残余牙槽嵴吸收方面的疗效。对13例牙槽嵴萎缩患者在手术过程中出现的并发症以及牵张后6个月内再生组织的定量变化进行了研究。
11例实现了预期的牙槽嵴增高。2例牵张失败。遇到了一些不寻常的并发症。
LEAD™牙槽牵张器能使牙槽骨持续增高,但存在稳定性问题。
