Abstract:
Objective:To provide anatomic image data for ossointegrated implant for patients with nasal defect. Methods: 100 cases of (50 males, 50 females) 3D spiral CT images of normal bone of skull were measured with mimics 10.01 software. Results: The minimum distance between the root tips of central incisor and the anterior nasal floor was 13.03 in males and 11.06 in females. The minimum distance between the root tips of lateral incisor and the anterior nasal floor was 15.95 mm in males and 13.04 mm in females, the minimum thickness of palatine process 6mm inferior to piriform aperture was 9.96 mm, the minimum thickness of alveolus 6mm inferior to piriform aperture was 11.57 mm in males and 10.61 mm in females, the thickness of glabella adjoin to frontal sinus was 3.57mm. Conclusion: The lateral incisor region is an optimal one for nasal implants 4-8 mm in length. The inclined direction can either be forward or backward. When the vertical bone depth is not enough, horizontal placement of the implants in the inferior region of piriform should be considered. 4-8 mm implants is suitable in this region. The glabella region is not optimal but an alternative option for nasal implants.
