Assessment of bone channels other than the nasopalatine canal in the anterior maxilla using limited cone beam computed tomography

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.

Background and aims. Because of increasing concerns about surgeries in the anterior maxilla, including implant placement, it is necessary to examine the morphology of the nasopalatine canal and its surrounding bones. This study aimed to analyze the shape and position of the nasopalatine canal and incisive foramen using cone-beam computed tomography (CBCT). Materials and methods. CBCT images of 110 patients referred to Hamadan School of Dentistry were examined. The size and shape of the nasopalatine canal and incisive foramen, the distance between the incisive foramen and the anterior nasal spine, and the distance between the anterior border of the nasopalatine canal and the labial surface of the buccal plate were recorded. Results. The nasopalatine canal length decreased and its diameter increased with aging. The canal was found to be longer and wider in men. Patients without incisors had longer and thicker nasopalatine canals. The distance from the nasopalatine canal to the labial surface of the buccal plate was not gender-related but decreased with age. The distance to the labial cortical surface decreased significantly with loss of incisors. Conclusion. Given the diversities in the size and shape of nasopalatine canals, it is highly important to perform CBCT to prevent neurovascular damage.

Objective: To evaluate the dimensions of the nasopalatine canal (NPC) and its relationship with the maxillary central incisors (MCI) using cone-beam computed tomography (CBCT) and to determine variations in the NPC in relation to age and gender. Methods: CBCT scans from 333 patients (67% female; 35.9 ± 14.6 years) were included. The CBCT scan was analyzed to determine the length and diameter of the NPC, the distance between the NPC and the MCI, and to evaluate the morphology of the NPC. The data were analyzed using the independent Student's t-test, the Mann–Whitney and Kruskal–Wallis tests, and Dunn's post-test (p < 0.05). Results: The average diameter and length of the NPC were 2.92 ± 0.91 mm and 12.67 ± 3.32 mm, respectively. The minimum and maximum distance between the MCI and the NPC were 0.78 ± 0.42 mm and 2.56 ± 1.38 mm, respectively. The NPC of male patients was greater in length compared with the female patients (p < 0.05). The majority presented a funnel-like morphology (34.1%), followed by a cylindrical morphology (27.5%). Conclusions: There was variability in the dimensions of the NPC and its relationship with the MCI, which was influenced by gender and age.
