A simple technique is described for alveolar reconstruction in cases where resorption has already occurred. The palatal core graft allows immediate regeneration of vertical, horizontal, and combined defects at the alveolus with minimal donor site morbidity and time consumption.
Seventeen patients (10 female and 7 male) were treated over a 1-year period. Bone core grafts from the palatal vault were harvested with a trephine and used for alveolar reconstruction in the esthetic zone. Patient age and gender, type and location of the defect, size of the graft, simultaneous tooth removal, simultaneous implant placement, need for soft tissue coverage, and postoperative complications were recorded.
Mean length of the grafts was 12.5 mm (range 9 to 14 mm). Mean width was 7.3 mm (range 5 to 9 mm). In 11 cases, simultaneous tooth removal was performed and a connective tissue flap with posterior pedicles was used. Patients did not experience discomfort in the donor area. Sixteen cases were successfully restored with single implants and crowns
Material for osseous reconstruction should ideally be autologous and easy to harvest and provoke minimal morbidity. The palatal core graft compares favorably with previously described techniques and donor sites for alveolar reconstruction.
In this preliminary report, experience with a new technique for alveolar reconstruction is presented. The "palatal core graft" for alveolar reconstruction is effective and easy to harvest and has low donor site morbidity, allowing 3-dimensional restoration of alveolar defects.
描述一种用于已发生吸收情况的牙槽嵴重建的简单技术。腭部骨芯移植可使牙槽嵴的垂直、水平及复合性缺损即刻再生，供区并发症和时间消耗最小。
在1年时间里对17例患者（10例女性，7例男性）进行了治疗。用环钻从腭穹窿获取骨芯移植片，用于美学区域的牙槽嵴重建。记录患者的年龄和性别、缺损类型和位置、移植片大小、同期拔牙、同期种植体植入、软组织覆盖需求及术后并发症。
移植片的平均长度为12.5毫米（范围9至14毫米）。平均宽度为7.3毫米（范围5至9毫米）。11例患者进行了同期拔牙，并使用了带后蒂的结缔组织瓣。患者在供区未感到不适。16例患者通过单颗种植体和牙冠成功修复。
理想的骨重建材料应是自体的，易于获取，且引发的并发症最少。腭部骨芯移植与先前描述的牙槽嵴重建技术和供区相比具有优势。
在本初步报告中，介绍了一种牙槽嵴重建新技术的经验。用于牙槽嵴重建的“腭部骨芯移植”有效且易于获取，供区并发症少，可实现牙槽嵴缺损的三维修复。
