Abstract：
UNASSIGNED: To systematically review existing scientific literature to determine, compare and evaluate the sinus complication and survival rates of quad zygoma against two zygomatic implants with combination of two regular implants in atrophic maxilla in adults.
UNASSIGNED: Review was performed in accordance with preferred reporting items for systematic reviews and meta-analysis guidelines and registered in PROSPERO-CRD42023392721 Electronic databases like PubMed, Google scholar and EBSCO host were searched from 2000 to December 2022 for studies reporting treatment of Atrophic maxilla with either quad zygoma or two zygomatic implants in combination with two regular implants. Quality assessment was evaluated using Cochrane risk of bias-2 tool for randomized controlled trials (RCT). The risk of bias summary graph and risk of bias summary applicability concern was plotted using RevMan software version 5.3. The odds ratio (OR) and standardized mean difference (SMD) were used as summary statistic measure with random effect model and p value < 0.05 as statistically significant.
UNASSIGNED: Eleven studies fulfilled the eligibility criteria and were included in qualitative synthesis, of which only nine studies were suitable for meta-analysis. The pooled estimate through the odds ratio 0.59 signifies that the quad zygomatic implants on an average has 0.59 (0.18-1.93) times or odds of developing sinus complications while the SMD signifies that better survival rate (SR) on an average is 0.35 (- 0.61 to 1.30) times more by two zygomatic implants with combination of two regular implants as compared to quad zygomatic implants (p > 0.05). Publication bias through the funnel plot showed asymmetric distribution with systematic heterogeneity.
UNASSIGNED: Two zygomatic implants in combination with two regular implants provides better survival rate and less sinus complications compared to quad zygoma in atrophic maxilla. Despite the high SR observed, there is a need to conduct more randomized controlled clinical trials to examine their efficacy in comparison with other techniques.

摘要：
■要系统地审查现有的科学文献，以确定，比较和评估成人萎缩性上颌骨中两种zy骨种植体与两种常规种植体的联合治疗的窦并发症和生存率。
■根据系统评价和荟萃分析指南的首选报告项目进行审查，并在PROSPERO-CRD42023392721电子数据库（如PubMed，从2000年至2022年12月，对Google学者和EBSCO宿主进行了搜索，以研究报告使用四核zygoma或两个zy骨植入物结合两个常规植入物治疗萎缩性上颌骨的研究。使用Cochrane偏见风险-2工具对随机对照试验（RCT）进行质量评估。使用RevMan软件版本5.3绘制偏差风险汇总图和偏差风险汇总适用性问题。以比值比（OR）和标准化均差（SMD）作为汇总统计量，随机效应模型和p值<0.05为统计学意义。
■11项研究符合资格标准，并被纳入定性综合。其中只有9项研究适合进行荟萃分析。通过比值比0.59得出的汇总估计值表明，与四zu植入物相比，四zy植入物平均具有0.59（0.18-1.93）倍或发生鼻窦并发症的几率，而SMD表明平均存活率（SR）比两个常规植入物的组合高0.35（-0.61至1.30）倍（p>0.05）。通过漏斗图的出版偏差显示出具有系统异质性的不对称分布。
■在萎缩性上颌骨中，与两个常规植入物结合使用的两个zy骨植入物可提供更好的存活率和更少的窦并发症。尽管观察到高SR，与其他技术相比，有必要进行更多的随机对照临床试验，以检查其疗效。
