“…Nevertheless, to the best of our knowledge, this investigation included the largest sample analyzed so far. Regarding the anatomic variations of the canal, results showed the Y‐shaped type as the most common, being consistent with previous studies . On the contrary, other reports on Turkish population found the single canal as the most common variation, being Y‐shaped the least observed .…”

“…Similarly, in this investigation, the canal angulation—in reference to the palatal plane—was identified as 106.15°±8.57. Lopez‐Jornet et al demonstrated a mean canal angulation of 74.16° to the horizontal plane. Also, when measuring the relationship between the canal and a line perpendicular to the palate, an angulation of 17.09° has been reported …”

“…Several studies examined the canal shape, length, curvature, as well as some factors that are thought to affect canal morphology, such as ethnicity, gender, age, and presence or absence of teeth . In addition, Mraiwa et al and Lopez‐Jornet et al described buccal bone width anterior to the nasopalatine canal. In 2015, Jia et al studied virtual implant placement in the anterior maxilla in both dentate and partially edentulous patients.…”

Background The nasopalatine canal (NPC) is of special importance when considering implant therapy in the maxillary central incisors' region. Purpose To investigate the incidence of NPC perforation in relation to virtual immediate implant placement. Materials and Methods A search through the cone beam computed tomography (CBCT) database of The University of Oklahoma—College of Dentistry was conducted. First, canal related measurements were conducted. Second, digital prosthetic planning was performed. Then, immediate implants were virtually placed and additional measurements were performed. Perforation rate was assessed. Last, data obtained was statistically analyzed. Results A total of 217 scans fulfilled the inclusion criteria. Only 8% of cases showed NPC perforation. The perforation occurred at mid‐third of the implant or at the mid and apical third in 33% and 22% of the cases, respectively. A statistically significant association was found between perforation of NPC and bone width palatal to the root of the central incisor (P < .0001) as well as canal angulation (P = .0196). NPC angulation (°) and palatal bone width (mm) predisposed to a higher risk of perforation. Only 27.78% of the perforations could be overcome by the installation of shorter implants. Conclusions Low incidence of NPC perforation could be expected when immediately placing implants in the maxillary incisor region.

Purpose: The study was performed to evaluate variability in nasopalatine canal using cone beam computed tomography (CBCT) in relation to age and gender. The study also provides an insight while considering anterior maxillary implants. Materials and Methods: The study included 200 subjects aged between 19 and 67 years who were divided into the following 3 groups: 1) 19 -34 years old; 2) 35 -49 years old; 3) >50 years old. The male and female subjects were 104 and 96 respectively. After obtaining a prior consent, CBCT was performed using a standard exposure and patient positioning protocol. The CBCT volume was sliced in three planes (X, Y, and Z) and was sequentially analyzed for the location, morphology and morphometric dimensions of the nasopalatine canal. The correlation of age and gender with all the variables were evaluated. Results: The present study revealed statistically significant differences in the length of the nasopalatine canal based on the age group. The slanted and the cylindrical variety of the nasopalatine canal were commonly observed in the study. However, no statistical differences were noted in the other variables such as number of openings at the nasal fossa, diameter of the incisive fossa, angulation of the canal as viewed in the sagittal sections and antero-posterior dimensions of the canal in the sagittal sections. Conclusion: The present study demonstrates the variability observed in the anatomy and morphology of the nasopalatine canal which is an important landmark for placing dental implants in the anterior maxillary region.
