摘要

通过骨壳技术进行的水平和垂直嵴增强提供了可预测的结果。外斜嵴是骨板采集最常用的供体部位,其次是下颌联合。侧窦壁和腭也被描述为可供选择的供区。本初步病例系列报道了一种骨壳技术,该技术使用刀口嵴的冠状段作为骨壳治疗连续5例(20个部位)患有严重下颌水平嵴萎缩和足够嵴高度的无牙患者。随访时间为1至4年。在新形成的脊嵴下方1毫米和5毫米处的平均水平骨增量分别为3.6±0.76毫米和3.4±0.92毫米。所有患者的嵴体积都得到了充分恢复,可以分阶段植入。在20个部位中的2个部位,植入时需要额外的硬组织移植物。利用重新定位的嵴段的优点如下:供体和受体部位相同,没有主要的解剖结构受损,初次闭合伤口不需要骨膜释放切口和皮瓣推进,并且由于肌肉张力降低,伤口裂开的风险降至最低。

Bone Shell Technique with Relocated Crestal Ridge Segment for Anterior Horizontal Mandibular Ridge Atrophy: A Case Series.

Horizontal and vertical ridge augmentation via the bone shell technique provides predictable outcomes. The external oblique ridge is the most-used donor site for bone plate harvesting, followed by the mandibular symphysis. The lateral sinus wall and the palate have also been described as alternative donor sites. This preliminary case series reports a bone shell technique that used the coronal segment of the knife-edge ridge as a bone shell in five consecutive edentulous patients (20 sites) with severe mandibular horizontal ridge atrophy and adequate ridge height. The follow-up period was 1 to 4 years. The average horizontal bone gains at 1 mm and 5 mm below the newly formed ridge crest were 3.6 ± 0.76 mm and 3.4 ± 0.92 mm, respectively. Ridge volume was sufficiently restored in all patients to enable implant placement in a staged approach. In 2 of the 20 sites, additional hard tissue grafts were required at implant placement. The advantages of utilizing the relocated crestal ridge segment are as follows: The donor and recipient sites are the same, no major anatomical structures are compromised, periosteal releasing incisions and flap advancement are not required for primary wound closure, and the risk of wound dehiscence is minimized due to reduced muscle tension.

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.
