영문 초록

In dental implantation, comprehension on the anatomy of maxillae, mandible and its surrounding structures is very important, and this can also determine success or failure of the operation. The author measured the distance with a caliper from alveolar crest to the floor of maxillary sinus and nasal cavity on the traced paper of orthopantomograms. For this study, the author selected 320 orthopantomograms of normal adults and divided the cases into 8 groups by age and sex ; group I (20-39，male), group II (20 — 29, female), group III (30—39, male), group IV (30—39, female), group V (40—49，male), group VI (40—49，female), group VII (above 50，male), group Vffl (above 50, female). The results were as followed. 1. In the maxillae, the maximum and minimum distance between the floor of maxillary sinus and alveolar crest of 3rd molar area was 16.74± 2.53mm and 7.83± 2.81mm, respectively. In the 2nd molar area, maximum was 14.69+ 4.04mm and minimum was 8.45± 2.16mm, and in the 1st molar area, maximum was 14.34± 2.45mm and minimum was 7.24士 2.15mm. In the 2nd premolar area, maximum was 19.19土 2.62mm and minimum was 12.53± 3.41丽, and in the 1st premolar area, maximum was 23.50± 2.46mm and minimum was 14.87 ± 3.07 mm. 2. The maximum and minimum distance between the floor of nasal cavity and alveolar crest of central incisor area was 35.50± 2.02mm and 26.58± 2.88mm, respectively. In the lateral incisor area, maximum was 34.33± 2.85mm and minimum was 25.23± 2.46mm. 3. No significant difference was shown by comparing left and right side of each group. 4. In comparing each sex, classified by age, no significant difference has been shown in their twenties and thirties, but more amount of resisdual alveolar bone of maxillae has been shown in female group than in male group in their late of forties. 5. As aging, residual alveolar bone of maxilla is reduced due to alveolar bone resorption and pneumatization of maxillary sinus.
