摘要
研究目的这项回顾性研究的主要目的是评估颧骨种植体（ZIs）穿透或未穿透颧骨外表面时，颧骨周围并发症（PZCs）发生率的差异：这项研究包括32名上颌骨无缺损或潜在上颌骨无缺损的患者，他们都接受了颧骨种植手术。根据术后 CBCT 检查种植体顶端是否穿透颧骨外表面，将患者分为穿透组（P 组）和未穿透组（N 组）。同时测量假体的延伸长度、穿透部分以及相应位置的皮肤厚度。定期进行临床随访，直至术后两年。记录PZC的发生情况（包括颧周感染、皮肤麻木、非感染性疼痛和异物感）。采用混合效应逻辑模型比较 P 组和 N 组并发症发生率的差异，并计算几率比（OR）。然后用同样的模型确定延伸长度、穿透截面和皮肤厚度对 P 组的影响：32名患者共植入了71枚ZI，其中P组37枚，N组34枚。在两年的随访中，共有 13 个植入体发生了 PZC，总并发症发生率为 18.3%。其中，P 组的发生率为 29.7%，N 组为 5.9%（OR = 6.77）。在 P 组中，不同延伸长度的并发症发生率有显著差异，而穿刺部位和皮肤厚度对并发症发生率没有统计学意义：结论：在本研究的限制下，为将 PZCs 的风险降至最低，放置 ZI 时应避免顶端穿透颧骨外表面。
Peri-zygomatic complications on zygomatic implants with or without penetrating the external surface of zygoma: A 2-year retrospective study
Objectives
The main purpose of this retrospective study was to assess the difference in the incidence of peri-zygomatic complications (PZCs) when zygomatic implants (ZIs) penetrate or do not penetrate the external surface of zygoma.
Materials and Methods
This study included 32 patients with edentulous maxillae or potentially edentulous maxillae undergo zygomatic implantation. The patients were divided into the penetration group (P-group) and the non-penetration group (N-group) according to whether the apex of implants penetrated the external surface of zygoma in postoperative CBCT. The extension length, the penetration section of the implants, and the skin thickness at the corresponding position were simultaneously measured. Clinical follow-up was conducted regularly until 2 years after surgery. The occurrence of PZCs (including peri-zygomatic infection, skin numbness, non-infectious pain, and foreign body sensation) was recorded. A mixed effect logistic model was used to compare the difference of complication rate between the P-group and the N-group, and odds ratio (OR) was calculated. Then identify the impact of the extension length, penetration section and skin thickness in P-group with the same model.
Results
A total of 71 ZIs were implanted in 32 patients, including 37 implants in the P-group and 34 implants in the N-group. During the 2-year follow-up, a total of 13 implants occurred PZCs, with an overall complication rate of 18.3%. Thereinto, the incidence rate was 29.7% in the P-group, and 5.9% in the N-group (OR = 6.77). In P-group, there was a significant difference in complication rate of different extension lengths, while the penetration section and skin thickness had no statistical significance on the complication rate.
Conclusion
Under the limitation of this study, to minimize the risk of PZCs, ZI should be placed in a manner that avoids the apex penetrating the external surface of the zygoma.
期刊介绍：
The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal.
The range of topics covered by the journals will include but be not limited to:
New scientific developments relating to bone
Implant surfaces and their relationship to the surrounding tissues
Computer aided implant designs
Computer aided prosthetic designs
Immediate implant loading
Immediate implant placement
Materials relating to bone induction and conduction
New surgical methods relating to implant placement
New materials and methods relating to implant restorations
Methods for determining implant stability
A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
