Background: The mandibular third molar is the most common tooth to become impacted than other teeth, often causing more complications in the process of growing, influence to the lives of patients. Removal of wisdom teeth is one of the most common dental surgical procedures, is an invasive intervention caused significant injury to the bone and soft tissue, so hard to avoid possible complications after surgery. Understand the relationship between degree of impaction and healing after mandibular wisdom tooth surgery will bring many benefits to surgeons and patients. The purpose of this study is to evaluate the degree of impaction of mandibular third molar and explore the relationship between healing after mandibular wisdom tooth surgery with the degree of impaction. Materials and method: The study consisted of 40 patients, average age 29.38 ± 9.8 a impacted mandibular third molar and cause complications, tooth extraction is indicated. All are to be attended to, determine the degree of impaction, wisdom tooth surgery. Evaluate the healing through pain, swelling, limited mouth open after 2 days, 1 week and 2 weeks. Result: Correlation of wisdom teeth to ramus and adjacent teeth mainly type I (45%) and type II (35%), type III accounted for the lowest rates (20%). Relative depth of wisdom teeth in the bone mainly position A (45%), B position also accounts for a significant proportion (35%), positions C (20%). Correlation of wisdom teeth axis to adjacent teeth: mesioangular impactions (50%) and horizontal (30%), distoangular impaction (2.5% and 5%), vertical impaction (12, 5%). Pain, swelling, limited mouth open only happen the first two days in groups I and II, group III of symptoms until a week after surgery. Conclusion: There is correlation between the degree of impaction and healing after mandibular wisdom tooth surgery. Degree of as much impaction, the level of pain, swelling, limited mouth open higher. Key words: mandibular third molar; impaction
