Surgical removal of impacted mandibular third molars frequently require tooth
sectioning or bone removal. In this study, 361 mesioangular or horizontal impacted
mandibular third molars are removed surgically by tooth section, the methods of tooth
section are classified as 4 stages and 12 grades in the number of times and technics of
crown or roots section and difficulties. Grades and their cases are following:
1. occlusal crown first section(100.28%) 2. distal crown first section(69.19%) 3. occlusal
crown second section(29.8%) 4. distal crown second section(52.14) 5. occlusal crown first
section and root section(10.3%) 6. distal crown second and root section(27.7%) 7.
occlusal crown third section(3.1%) 8. distal crown third section(22.6%) 9. occlusal crown
second section and root section(13.3%) 10. distal crown section and root section(17.5%)
11. occlusal crown third section and root section(2.1%) 12. distal crown third section and
root section(17.5%).
