The aim of the ITI Consensus Workshop on zygomatic implants was to provide Consensus Statements and Clinical Recommendations for the use of zygomatic implants.
Three systematic reviews and one narrative review were written to address focused questions on (1) the indications for the use of zygomatic implants; (2) the survival rates and complications associated with surgery in zygomatic implant placement; (3) long-term survival rates of zygomatic implants and (4) the biomechanical principles involved when zygoma implants are placed under functional loads. Based on the reviews, three working groups then developed Consensus Statements and Clinical Recommendations. These were discussed in a plenary and finalized in Delphi rounds.
A total of 21 Consensus Statements were developed from the systematic reviews. Additionally, the group developed 17 Clinical Recommendations based on the Consensus Statements and the combined expertise of the participants.
Zygomatic implants are mainly indicated in cases with maxillary bone atrophy or deficiency. Long-term mean zygomatic implant survival was 96.2% [95% CI 93.8; 97.7] over a mean follow-up of 75.4 months (6.3 years) with a follow-up range of 36-141.6 months (3-11.8 years). Immediate loading showed a statistically significant increase in survival over delayed loading. Sinusitis presented with a total prevalence of 14.2% [95% CI 8.8; 22.0] over a mean 65.4 months follow-up, representing the most common complication which may lead to zygomatic implant loss. The international experts suggested clinical recommendations regarding planning, surgery, restoration, outcomes, and the patient's perspective.
ITI 颧骨种植体共识研讨会的目的是提供关于颧骨种植体使用的共识声明和临床建议。
为了回答关于（1）颧骨种植体使用的适应证；（2）颧骨种植体放置手术的生存率和相关并发症；（3）颧骨种植体的长期生存率；（4）在功能负荷下放置颧骨种植体时涉及的生物力学原理的 4 个具体问题，编写了 3 项系统评价和 1 项叙述性综述。基于这些综述，然后成立了 3 个工作组，制定共识声明和临床建议。这些声明在全体会议上进行了讨论，并在德尔菲（Delphi）环节中最终确定。
共有 21 项共识声明是从系统综述中得出的。此外，该小组还根据共识声明和参与者的综合专业知识制定了 17 项临床建议。
颧骨种植体主要适用于上颌骨萎缩或缺失的病例。在平均 75.4 个月（6.3 年）的平均随访中，长期平均颧骨种植体存活率为 96.2% [95%CI 93.8; 97.7]，随访范围为 36-141.6 个月（3-11.8 年）。即刻负载与延迟负载相比，存活率有统计学显著提高。在平均 65.4 个月的随访中，鼻窦炎的总患病率为 14.2% [95%CI 8.8; 22.0]，是最常见的并发症，可能导致颧骨种植体丢失。国际专家提出了关于规划、手术、修复、结果和患者视角的临床建议。
