The aim of this systematic review and meta-analysis was to determine the accuracy of different methods of measuring horizontal condylar guidance (HCG) angle in comparison with extraoral Gothic arch tracing for completely edentulous patients.
This was a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Two reviewers searched the EBSCOhost, Cochrane Library, and PubMed/MEDLINE databases and the Google Scholar search engine for in vivo studies, randomized controlled trials, cross-sectional studies, and quasi-experimental studies published from January 2005 to December 2022 on various other methods of determining HCG angle in completely edentulous patients compared with extraoral Gothic arch tracing method.
Meta-analysis was conducted from the reported quantitative data.
A total of 513 articles were obtained from different electronic databases, of which 22 studies were included for qualitative synthesis and 20 studies were included for meta-analysis. For the right side, a statistically significant difference was observed for panoramic radiograph (P < 0.05, pooled mean difference = 5.08 [2.17, 7]) and cephalogram (P < 0.05, pooled mean difference = 10.65 [8.81, 12.49]), whereas no statistically significant difference was observed for cone-beam computed tomography (CBCT) (P = 0.41, pooled mean difference = 4.39 [-6.10, 14.87]) and protrusive interocclusal wax record (P = 0.92, pooled mean difference = -0.45 [-9.62, 8.72]) as compared with extraoral Gothic arch tracing method. For the left side, a statistically significant difference was observed for panoramic radiograph (P < 0.05, pooled mean difference = 5.07 [1.95, 8.18]) and cephalogram (P < 0.05, pooled mean difference = 10.24 [8.65, 11.83]), whereas no statistically significant difference was observed for CBCT (P = 0.31, pooled mean difference = 4.05 [-3.74, 11.84]) and protrusive interocclusal wax record (P = 0.72, pooled mean difference = -1.21 [-7.86, 5.43]) as compared with extraoral Gothic arch tracing method.
The cephalogram and panoramic radiograph obtained higher HCG angles in completely edentulous patients than extraoral Gothic arch tracing.
本系统评价和荟萃分析的目的是确定与哥特式弓描记法相比，不同测量水平髁导角（HCG）方法在完全无牙患者中的准确性。
这是一项系统评价和荟萃分析，遵循首选报告项目为系统评价和荟萃分析指南。
两名评审员在 EBSCOhost、Cochrane 图书馆和 PubMed/MEDLINE 数据库以及 Google Scholar 搜索引擎中搜索了 2005 年 1 月至 2022 年 12 月期间发表的关于各种其他方法确定完全无牙患者 HCG 角度的体内研究、随机对照试验、横断面研究和准实验研究，与哥特式弓描记法进行比较。
从报告的定量数据进行荟萃分析。
从不同的电子数据库中获得了 513 篇文章，其中 22 项研究进行了定性综合分析，20 项研究进行了荟萃分析。对于右侧，全景片（P<0.05，合并平均差异=5.08[2.17，7]）和头颅侧位片（P<0.05，合并平均差异=10.65[8.81，12.49]）有统计学显著差异，而锥形束 CT（CBCT）（P=0.41，合并平均差异=4.39[-6.10，14.87]）和前伸牙合记录蜡块（P=0.92，合并平均差异=-0.45[-9.62，8.72]）与哥特式弓描记法相比，无统计学显著差异。对于左侧，全景片（P<0.05，合并平均差异=5.07[1.95，8.18]）和头颅侧位片（P<0.05，合并平均差异=10.24[8.65，11.83]）有统计学显著差异，而 CBCT（P=0.31，合并平均差异=4.05[-3.74，11.84]）和前伸牙合记录蜡块（P=0.72，合并平均差异=-1.21[-7.86，5.43]）与哥特式弓描记法相比，无统计学显著差异。
与哥特式弓描记法相比，头颅侧位片和全景片在完全无牙患者中获得的 HCG 角度更高。
