To examine the dimensions (width, length, and height) of the maxillary tuberosity (MT) and their correlations with age and sex, and to identify different anatomical types for adequate positioning of miniscrews in this area.
The study enrolled 39 patients attending the University of Valencia. The patients comprised 21 males and 18 females with a mean age of 39.7 ± 8.4 years. The dimensions of all 78 MTs were measured on cone beam computed tomography (CBCT) images using Invivo Dental 5 software.
The intraobserver and interobserver errors were good for all measurements. A total of 858 MT measurements were taken. The widths were greater in men than in women, with significant differences. The MT dimensions showed correlations with patient age, whereby older patients presented with greater widths and lengths, but reduced heights. Three different anatomical types were detected according to patient age.
The dimensions (width, length, and height) of the MT vary according to patient age and sex. The MT dimensions conform to particular anatomical types, which should be taken into account when placing miniscrews in this region.
研究上颌结节（MT）的尺寸（宽度、长度和高度）及其与年龄和性别的相关性，并确定该区域微型螺钉适当定位的不同解剖类型。
该研究纳入了39名前往瓦伦西亚大学就诊的患者。患者包括21名男性和18名女性，平均年龄为39.7±8.4岁。使用Invivo Dental 5软件在锥形束计算机断层扫描（CBCT）图像上测量所有78个MT的尺寸。
所有测量的观察者内和观察者间误差均良好。共进行了858次MT测量。男性的宽度大于女性，差异有统计学意义。MT尺寸与患者年龄相关，老年患者的宽度和长度更大，但高度更小。根据患者年龄检测到三种不同的解剖类型。
MT的尺寸（宽度、长度和高度）因患者年龄和性别而异。MT尺寸符合特定的解剖类型，在该区域放置微型螺钉时应予以考虑。
