Abstract

Purpose: Ponticulus posticus (PP) is a bony protrusion located between the posterior portion of the superior articular process and the posterolateral portion of a posterior arch of the atlas vertebrae in the cervical spine. The aim of this study is to verify the presence of different types of PP in a Southern Italian pre-orthodontic cohort to understand its correlation with skeletal class and maturity.

Methods: A case-control retrospective study was conducted, utilizing 212 latero-lateral telecranium radiographs to analyze skeletal maturity according to the cervical vertebral maturation method, the Angle's classification of malocclusion (I, II, or III), and the presence or absence of the PP, whether complete (c-PP) or partial (p-PP). A total of 212 lateral cephalograms were analyzed.

Results: Of the 72 male patients, 67 (93%) exhibited PP, and 116 (88%) were PP. The chi-square value was 0.001, while Cramer's V was 0.270, indicating a significant correlation between age groups and PP presence, and a very strong association overall. Out of the 41 complete PP cases, class I was notably more prevalent than classes II and III.

Conclusion: Orthodontists should carefully consider PP when assessing and treating individuals with or without skeletal discrepancies and dental anomalies.

后牙本质和骨骼错合畸形：一项在意大利南部正畸前法庭进行的试点研究。

目的：后盂（PP）是位于颈椎上关节突后部和寰椎后弓后外侧之间的骨性突起。本研究的目的是验证意大利南部正畸前队列中是否存在不同类型的PP，以了解其与骨骼等级和成熟度的相关性：方法：我们进行了一项病例对照回顾性研究，利用212张侧位远程颅骨X光片，根据颈椎成熟度方法、安格尔错颌畸形分类（I、II或III）以及是否存在PP（完全性PP（c-PP）或部分性PP（p-PP））来分析骨骼成熟度。共分析了 212 张头颅侧位片：在 72 名男性患者中，67 人（93%）表现为 PP，116 人（88%）为 PP。秩方值为 0.001，Cramer's V 值为 0.270，表明年龄组与 PP 存在显著相关性，总体上关联性很强。在 41 个完整的 PP 病例中，I 类明显多于 II 类和 III 类：正畸医生在评估和治疗有或没有骨骼差异和牙齿畸形的患者时，应仔细考虑 PP。
