摘要: 目的:探讨严重先天缺牙患者选择双侧双颧种植的可行性。方法:基于锥形束CT(cone-beam CT, CBCT)对21例严重先天缺牙患者行双侧双颧种植设计,测量虚拟植入的颧种植体在颧骨段影像学水平上的种植体-骨接触值(radiographic bone-to-implant contact, rBIC)。采用SPSS 25.0软件包对数据进行统计学分析。结果:20例患者完成双侧双颧种植设计,其中,男12例,女8例,平均年龄(22.8±5.3)岁。共虚拟植入80颗颧种植体,平均颧骨段rBIC为(13.85±3.29) mm。40颗近中颧种植体和40颗远中颧种植体的平均颧骨段rBIC分别为(13.80±3.74) mm和(13.90±2.81) mm(P>0.05);男性近中颧种植体和远中颧种植体的平均颧骨段rBIC分别为(14.21±4.08) mm和(14.31±3.18) mm,略大于女性的(13.18±3.18) mm(P>0.05)和(13.29±2.10) mm(P>0.05)。15颗窦外型、46颗窦壁型和19颗窦内型颧种植体的平均颧骨段rBIC分别为(16.27±2.95)、(13.87±3.10)和(11.88±2.78) mm,窦外型与后两者存在显著差异(P<0.05)。结论:双侧双颧种植对严重先天缺牙患者是一项可行的治疗方案,颧种植体能获得满意的颧骨段rBIC,为义齿受力提供稳定的支持和固位。

Abstract: PURPOSE: The aim of this study was to analyze the feasibility of zygomatic implant quad approach in patients with tooth agenesis. METHODS: Based on the data from cone-beam CT (CBCT), twenty one patients with tooth agenesis who were planned to receive zygomatic implant quad approach were enrolled. The radiographic bone-to-implant contact (rBIC) of each zygomatic implant placed virtually in patients' zygomatic segment was measured. SPSS 25.0 software package was used for statistical analysis. RESULTS: Twenty patients' plans of zygomatic implant quad approach were completed (12 men and 8 women). A total of 80 zygomatic implants were placed virtually and the average rBIC of zygomatic segment was (13.85±3.29) mm. The rBIC values of 40 mesial zygomatic implants and 40 distal zygomatic implants were (13.80±3.74) mm and (13.90±2.81) mm, respectively(P>0.05). The average rBIC in male of 24 mesial zygomatic implants and 24 distal zygomatic implants were(14.21±4.08) mm and(14.31±3.18) mm, respectively, slightly higher than those in female of 16 mesial zygomatic implants and 16 distal zygomatic implants, which were (13.18±3.18) mm and (13.29±2.10) mm, respectively. There was no significant difference between the two groups (P>0.05). The average rBIC of 15 extra sinus zygomatic implants, 46 against sinus lateral wall zygomatic implants and 19 intra-sinus zygomatic implants were (16.27±2.95), (13.87±3.10) and (11.88±2.78) mm, respectively. There was significant difference between the extra sinus zygomatic implants and the other two(P<0.05). CONCLUSIONS: It is feasible to plan zygomatic implant quad approach for patients with tooth agenesis. Zygomatic implants can get adequate rBIC in zygomatic segment and to provide sufficient support and retention of the superstructure.
