The aim of this study was to evaluate the interconnection between the type of nasopalatine canal (NPC) and morphometric characteristics of the anterior maxilla. The investigation involved 113 subjects, and the morphometric parameters were obtained using cone beam computed tomography (CBCT). NPC shapes were classified into four types: banana-, hourglass-, cylindrical-, and funnel-shaped (distribution of approximately 9, 25, 31, and 35%, respectively). The analysis revealed that the NPC shape was significantly connected with the morphometric properties of anterior maxilla horizontal dimensions. In general, a banana-shaped NPC was accompanied with an overall reduction in anterior maxilla diameters when compared to other NPC shapes, with no significant difference between the other three NPC shapes. Furthermore, the morphometric characteristics that depend on NPC shape at the sagittal cross-section were significantly correlated with diameters of the incisive foramen, nasal foramen, and NPC length. According to the results of our study, it seems that the presented analyses of morphometric data may allow useful insight into the algorithms of various interconnections between the measures obtained in the region of the anterior maxilla, which could be of interest for a time rationale approach when planning some surgical procedures, such as immediate dental implant placement planning.
本研究的目的是评估鼻腭管（NPC）类型与上颌前部形态学特征之间的相互关系。该研究涉及113名受试者，并使用锥形束计算机断层扫描（CBCT）获得形态学参数。NPC形状分为四种类型：香蕉形、沙漏形、圆柱形和漏斗形（分布比例分别约为9%、25%、31%和35%）。分析表明，NPC形状与上颌前部水平尺寸的形态学特性显著相关。一般来说，与其他NPC形状相比，香蕉形NPC伴随着上颌前部直径的整体减小，其他三种NPC形状之间无显著差异。此外，矢状面中依赖于NPC形状的形态学特征与切牙孔、鼻前孔直径以及NPC长度显著相关。根据我们的研究结果，似乎所呈现的形态学数据分析可能有助于深入了解上颌前部区域所获测量值之间各种相互关系的算法，这对于规划某些外科手术（如即刻牙种植体植入规划）时的时间合理性方法可能具有重要意义。
