AI Article Synopsis
- The study examines the anatomical features and dimensions of the nasopalatine canal and surrounding alveolar bone using cone beam computed tomography (CBCT) in a sample of 122 patients.
- Results reveal significant variability in the canal's morphology, with the majority being Y-shaped (52.45%), and highlight differences in dimensions based on gender, showing males typically have larger canal sizes and bone thickness.
- The findings emphasize the importance of evaluating the nasopalatine canal via CBCT before conducting surgeries in the anterior maxillary region to better plan for patient-specific anatomical variations.
Article Abstract
Background: Surgery of the anterior maxillary zone has a strong impact upon dental and facial aesthetics and function.
Purpose: To determine the anatomical characteristics and dimensions of the nasopalatine canal and alveolar bone using cone beam computed tomography (CBCT).
Materials And Methods: A retrospective, cross-sectional study was made of the nasopalatine canal in 122 randomly selected CBCT scans corresponding to 66 males (44.3%) and 56 females (55.6%). The following measurements were made: maximum length and diameters of the nasal and oral openings of the nasopalatine canal; distance from the crestal margin to the buccal wall (at apical, middle, and coronal level); and angulation of the nasopalatine canal. The anatomical variants were morphologically classified as follows: A (single canal), B (double canal), or C (Y-shaped canal).
Results: The anatomy of the nasopalatine canal showed important variability in terms of morphology and dimensions. Type A was observed in 48 patients (39.34%), type B in 10 (8.19%), and type C in 64 (52.45%). The mean diameter of the nasal opening or orifice was 3.02 ± 1.0 mm versus 3.29 ± 1.0 mm in the case of the oral opening. The mean length of the canal was 11.02 ± 2.4 mm. Significant differences were found between males and females, with greater canal dimensions and alveolar bone thickness values anterior to the nasal canal zone among males (p < .05).
Conclusions: Our study shows gender to exert a significant influence upon the anatomical dimensions of the anterior maxilla and incisor canal. Given the anatomical variability characterizing the nasopalatine canal, we recommend CBCT evaluation prior to any type of surgery of the anterior maxillary zone.

Nasopalatine duct cysts (NPDCs) are among the most common nonodontogenic cysts, typically located in the midline of anterior maxillary hard palate. They usually arise from the embryonic epithelial vestiges of the nasopalatine duct. NPDCs predominantly affect adult males, generally during their fourth decade of life.

This study presents retrospective 8-year clinical performance data from a patient cohort treated with immediately loaded maxillary full prostheses supported by zygomatic implants combined with implants placed in the nasopalatine canal, as a treatment for severely resorbed edentulous ridges. A retrospective analysis was conducted on data of maxillary edentulous patients with severe bone atrophy. All of them received zygomatic implants in combination with an implant placed in the nasopalatine foramen and an immediately loaded fixed temporary prosthesis in the first 24 hours.

The nasopalatine canal (NPC), an interosseous conduit in the anterior maxilla, plays a crucial role in various dental procedures, such as implant placement, orthodontics, and surgical interventions. Accurate anatomical characterization of the NPC is essential to avoid complications, as its morphometric variations can impact the nasopalatine nerve and vascular structures within the canal. Traditional radiography techniques are limited in displaying the canal's detailed anatomy due to issues like magnification and distortion.

Article Synopsis
- Effective management of unique anatomical structures, like the nasopalatine canal, is crucial for implant success, and topical oral oxygen therapy (TOOT) has emerged as a promising treatment due to its antibacterial and healing properties.
- A case involving a 33-year-old male showed postoperative palatal necrosis treated with TOOT gel after surgical intervention for a deficient maxillary ridge.
- The patient experienced significant healing within 12 days and complete recovery by day 34, suggesting TOOT with active oxygen gel can enhance wound healing in dental procedures.

Article Synopsis
- This study looked at whether measuring the size of the nasopalatine canal using special 3D images (CBCT) could help tell the difference between nasopalatine duct cysts and normal canals.
- They compared 19 patients with cysts to 164 people without to see how the sizes differed.
- The researchers found that certain measurements were really good at spotting cysts, with an accuracy rate of almost 99% for detecting them!
