中文摘要

目的 应用锥形束CT(CBCT)研究Bio-oss用于唇侧骨缺损种植牙的骨组织改建效果。方法 选择上前牙单颗牙唇侧骨缺损种植牙患者12例,种植体植入的同期应用Bio-oss骨粉行引导骨组织再生技术,保证唇侧具有2 mm以上骨厚度,术后6、12、24个月行CBCT检查,评价唇侧骨组织的厚度以及骨改建的情况。结果 术后6个月时,Bio-oss骨颗粒存在,与自体骨组织界限清晰,人工骨组织外形不规则;术后12个月时,人工骨颗粒与周边自体骨组织无明显分界,但整体呈高密度影像,无明显骨密质-骨松质界限,唇侧人工骨厚度降低35.12%;24个月时,人工骨与自体骨分界不清,形成明显的骨密质-骨松质界限,唇侧人工骨厚度降低36.73%。结论 Bio-oss人工骨在种植牙应用时骨组织量的改变主要发生在12个月内,唇侧人工骨厚度降低35.12%,24个月时可形成正常的骨密质-骨松质界限。

英文摘要

Objective This study aims to use cone beam CT(CBCT) analyses bone tissue remodeling following Bio-oss applied labial bone cracking for guided bone regeneration and to provide imaging guidance for guided bone regeneration techniques. Methods A total of 12 patients with labial bone cracking needed dental implant. Bio-oss was given after dental implant was implanted in the body to ensure 2 mm of labial bone thickness or more after surgery. The labial bone tissue thickness and reconstruction situations were evaluated at 6, 12, and 24 months postoperative using CBCT. Results Biooss bone particles existed, and clear boundaries with autologous bone tissue were observed after 6 months. The bone tissue was irregularly shaped. After 12 months, Bio-oss bone particles with surrounding bone tissue had no obvious boundaries. However, the whole Bio-oss bone tissue showed a high-density image. No obvious cortical bone-spongy bone boundaries were observed. Labial bone thickness reduced by 35.12%. Twenty-four months after implant surgery, unclear boundaries were observed between Bio-oss bone and autologous bone. Distinct cortical bone-spongy bone boundaries also existed. The labial bone thickness reduced by 36.73%. Conclusion Bone tissue changes mainly occurred within 12 months in Bio-oss bone application implant surgery. Labial bone thickness reduced by 35.12%, and normal cortical-cancellous bone.
