Objectives: To describe the clinical, radiological characteristics of patients with the third molar teeth lower, lower jaw and evaluate the effectiveness of the third molar and implant lower molar surgery using Piezotome ultrasound machine. Materials and methods: The study used the cross-sectional descriptive method, with no control intervention on 73 patients (36 women and 37 men, 15-71 years of age) with deviated lower wisdom teeth, who received surgical treatment with Piezotome at Can Tho Eye and Odonto-Maxillo-Facial Hospital from August, 2019 to August, 2020 by SPSS 18.0 software. Results: The percentage of subjects with postoperative swelling complications was 56.2% and 4.1% of jaw close. The rate of signs of pain was 98.6%; infection was 52.1%; jaw tightness was 11.0%; tooth decay 7 was 30.1%. The pederson's index of the difficult type was 57.5%; the new index for the difficult type was 34.2%; the time for the hard to spit was 39.7%. Conclusion: The subjects treating the under-erupted wisdom teeth all had clinical symptoms. In subclinical terms, 39.7% of subjects were in the difficult-to-extract group. The percentage of subjects with complications after surgery was low.
