Abstract


The author had investigated an anatomical analysis on the distributions of inferior alveolar nerve from the 80 cases of mandible (male 50, female 30) of Korean subjects. The results were as follows:
1. The origin of retromolar branch of the inferior alveolar nerve began a common stem with a molar branch.
2. The retromolar branch of the inferior alveolar nerve passed antero-inferiorly coinciding with the stem of the inferior alveolar nerve.
3. The distributions of end portion of retromolar branch released postero-superiorly and branch of treelike form.
4. The distributions of retromolar branch held a large part in the region of the mandibular third molar and retromolar triangle.
5. The retromolar branch showed a high rate to hold one in number.
6. The origin of retromolar branch held a large part posteriorly between the mandibular foramen and mental foramen.
7. The retromolar branch passed antero-posteriorly.
8. The distributions of retromolar branch showed a highe rate in the region between the mandibular 1st premolar and mandibular 1st molar.
9. The occurrence rate of the retromolar branch in the region of premolar showed 80 percent.
10. The number of inferior alveolar nerve in the region of premolar showed a highe rate to hold one in number.
11. The branch of the inferior alveolar nerve in the region of premolar released simple form.
12. The distributions of the branch of the inferior alveolar nerve in the region of premolar showed a higher rate in the region between the mandibular canine and mandibular premolar.
13. The origin of the branch in the region of the mandibular canine coincided with the turning parts opening the mental foramen.
14. The branch of the inferior alveolar nerve in the region of canine passed anteriorly -and `superioily with a dull curvature.
15. The inferior alvvolar nerve in the region of the mandidular canine released one or two branch in the vicinity of openinis and fan-like form showed a highe rate in the vicinity of the curvatures.
16. The distributions of the branch of the inferior alveolar nerve in the region of the mandibular canine showed a highe rate in the region between the mandibular centrals and First premolar.
17. The anastomosis of right and left branch of the inferior alveolar nerve in the region of the mandibular canine showed a great part in the combinations of communicating branch from the canine and centrals branch.
