ABSTRACT
STATEMENT OF PROBLEM:
Following tooth loss, the edentulous alveolar process of maxilla is affected by irreversible reabsorption process, with progressive sinus pneumatization leads to leaving inadquate bone height for placement of endosseous implants. Grafting the floor of maxillary sinus by sinus lifting surgery and augmentation of autologous bone or alternative bone material is a method of attaining sufficient bone height for maxillary implants placement and has proven to be a highty successful.PURPOSE:
This study was undertaken to clarify the morphometric characteristics of inferior maxillary sinus and alveolar process for installation of implants. MATERIAL ANDMETHOD:
Nineteen skulls (37 sinuses, 10M / 9F) obtained from the collection of the department of anatomy and cell biology of Hanyang medical school were studied. The mean age of the deceased was 69.9 years (range 44 to 88 years). The distance between alveolar border and inferior sinus margin at each tooth, the height of alveolar process and the thickness of cortical bone of the outer and inner table of alveolar process and the inferior wall of maxillary sinus were measured. RESULTS ANDCONCLUSION:
1. The septum of inferior maxillary sinus were observe 28 sides (76.%) and located at the third molar (52.6%) and the second molar (26.3%). The deepest points of inferior border of maxillary sinus were located the first or second molar. The distance between alveolar margin and the deepest point of inferior maxillary sinus is 9.7 +/- 4.9 mm. 2. The length of the outer table of alveolar process were 4.9-28.2 mm and the shortest point was between the first and the second molors. The thickness of them were 0.9-3.2 mm. The length of the inner table of alveolar process were 7.4-25.8 mm and the shortest point was between the first and the second molars. The thickness of the were 0.9-4.6 mm. The results of this study are useful anatomical data for installing of maxillary implants.
