Abstract

Introduction: The objective of this study was to determine the anatomical and technical parameters for the installation of dental implants in the pterygomaxillary region.

Materials and method: This is a cross-sectional imaging study. Twenty bilateral computed tomography scans (40 regions) were analyzed using the ImplantViewer program and subsequently tabulated in Microsoft Excel for statistical analysis in the GraphPad program with a 95% confidence level.

Results: The average implant length ranged from 14 to 18 mm, with an average of 16.2 mm (1.281 right and 16.05 left). The median density in the maxillary tuber region was 169 HU (211.7) (Hounsfield units), and in the pterygoid region, it was 559.55 HU (2.71.7) p-value < 0.0001. The average distance from the implant head to the floor of the maxillary sinus was 4.98 mm (3.058 right) and 4.41 mm (3.55 left), p-value 0.587. Regarding the pterygoid anatomical radiographic prediction (PARP classification), the most common was type 1, in 19 analyses, followed by type 4 in 7 analyses.

Conclusion: Pterygoid implants can be a safe and effective alternative for the rehabilitation of atrophic jaws. Tomographic analysis is essential to define the safe installation of implants in the pterygomaxillary region.

萎缩性上颌翼颌区翼状体植入的层析分析。

前言：本研究的目的是确定翼颌区种植体安装的解剖学和技术参数。材料和方法：这是一项横断面成像研究。使用ImplantViewer程序分析20个双侧计算机断层扫描（40个区域），随后在Microsoft Excel中制表，在GraphPad程序中进行统计分析，置信度为95%。结果：种植体平均长度为14 ~ 18 mm，平均16.2 mm（右1.281 mm，左16.05 mm）。上颌块茎区中位密度为169 HU (211.7) （Hounsfield单位），翼状骨区中位密度为559.55 HU (2.71.7)， p值为0.587。关于翼状骨解剖x线预测（PARP分类），最常见的是1型，在19例分析中，其次是4型，在7例分析中。结论：翼状假体是一种安全有效的颌骨萎缩修复方法。层析分析是必要的，以确定安全安装种植体在翼状颌区。
