title: [Preliminary study of anatomic relation among nasopalatine duct, central incisor root and floor of nasal cavity with X-ray measurement].
abstract: The authors studied anatomic constructure of anaterior maxilla. They observed the position relationships among nasopalatine duct, central incisor root and floor of nasal cavity through X-ray measurement. The results showed: (1) Average distance between the anterior wall of nasopalatine duct and cortical plate of anterior maxilla was 7.80 +/- 1.43 mm. (2) Average distance between the anterior wall of nasopalatine duct and central incisor root was 4.15 +/- 1.48 mm. (3) Average distance between the tip of central incisor root and floor of nasal cavity was 12.62 +/- 2.47 mm. (4) Average length of the nasopalatine duct was 15.04 +/- 2.20 mm. The results are beneficial of dental implantation and orthognathic surgery.
