Research method: Evaluation of 133 IMTMs on CBCT images of 85 patients. Results: Among the 133 IMTMs, the most common angulation was mesioangular, accounting for 47.3%. The highest point of IMTMs was located at or above the occlusal plane of the adjacent tooth 7 (position A) in 40.6% of cases. Type II impaction, characterized by a smaller bone width compared to the tooth width, accounted for 41.4%. Two-rooted teeth were predominant, representing 74.4% of cases. Non-contact between the inferior alveolar nerve and the tooth root was observed in 62.4% of cases, while contact was present in 37.6%. Conclusion: The study provided morphological characteristics of IMTMs on CBCT images at Morita Dental X-ray Center in Hanoi, first quarter of 2023, serving as a basis for planning appropriate surgical treatment.
