Abstract

Purpose: This study investigates the influence of vertical facial growth patterns on the morphology of the zygomatic buttress (ZB) donor site and its implications for preoperative planning in bone grafting.

Materials and methods: A total of 100 adult Cone beam computed tomography (CBCT) scans were analyzed and categorized into hypodivergent, normodivergent, and hyperdivergent groups based on SN-GoGn angles. Three-dimensional ZB models were created using semi-automatic segmentation, with key parameters-volume, surface area, thickness, and anteroposterior protrusion-measured using stable anatomical landmarks. Statistical analyses included descriptive statistics, one-way analysis of variance (ANOVA), Tukey's post-hoc tests, and Kruskal-Wallis H tests where necessary. A p-value < 0.05 was considered statistically significant.

Results: ZB morphology varied significantly across facial growth types. Hypodivergent faces exhibited the highest bone volume (533.25 ± 129.58 mm³), surface area (560.70 ± 99.76 mm²), total thickness (4.68 ± 1.91 mm), and bulge thickness (9.75 ± 2.51 mm). Normodivergent faces showed intermediate values for bone volume (394.39 ± 141.62 mm³), surface area (504.27 ± 108.54 mm²), and thickness (2.79 ± 1.05 mm total, 5.42 ± 2.45 mm bulge). Hyperdivergent faces had the lowest bone volume (259.00 ± 86.28 mm³), surface area (422.64 ± 95.59 mm²), total thickness (1.70 ± 0.49 mm), and bulge thickness (3.57 ± 1.66 mm). Anteroposterior protrusion also differed significantly, with hypodivergent faces showing the largest protrusion (21.56 ± 3.24 mm).

Conclusion: The ZB is a reliable donor site with morphology influenced by facial growth patterns. Preoperative radiographic assessment facilitates optimized surgical planning and tailored grafting strategies.

目的：本研究探讨了面部垂直生长模式对颧骨托（ZB）供体部位形态的影响及其对植骨术前规划的意义：分析了总共 100 张成人锥形束计算机断层扫描（CBCT）扫描图像，并根据 SN-GoGn 角度将其分为低发散组、正常发散组和高发散组。使用半自动分割技术创建了三维 ZB 模型，并使用稳定的解剖标志测量了关键参数--体积、表面积、厚度和前后突。统计分析包括描述性统计、单因素方差分析（ANOVA）、Tukey's 事后检验以及必要的 Kruskal-Wallis H 检验。P值小于0.05为具有统计学意义：不同面部生长类型的 ZB 形态差异显著。下发散型面部的骨量（533.25 ± 129.58 mm³）、表面积（560.70 ± 99.76 mm²）、总厚度（4.68 ± 1.91 mm）和隆起厚度（9.75 ± 2.51 mm）最高。正常发散面的骨量（394.39 ± 141.62 mm³）、表面积（504.27 ± 108.54 mm²）和厚度（总厚度（2.79 ± 1.05 mm）、隆起厚度（5.42 ± 2.45 mm）均处于中等水平。超发散面的骨量（259.00 ± 86.28 mm³）、表面积（422.64 ± 95.59 mm²）、总厚度（1.70 ± 0.49 mm）和隆起厚度（3.57 ± 1.66 mm）最低。前后突度也有显著差异，下发散面的突度最大（21.56 ± 3.24 毫米）：结论：ZB是一个可靠的供体部位，其形态受面部生长模式的影响。结论：ZB是一个可靠的供体部位，其形态受面部生长模式的影响。术前放射学评估有助于优化手术计划和定制移植策略。
