Background/purpose: Immediate implant placement in the mandibular anterior tooth region requires a thorough understanding of the alveolar bone anatomy for determining the ideal implant position and preventing labial bone perforation. The anatomical characteristics of the jaws are closely related to the sagittal root position (SRP) and labial concavity of the alveolar bone. This study evaluated SRP, labial concavity, and labial bone perforation in the mandibular anterior tooth region. Materials and methods: Cone-beam computed tomography images of 116 participants (696 teeth) were uploaded to medical imaging software. SRP classification, labial concavity of the alveolar bone, and labial bone perforation were analyzed. A t-test was performed to compare measurements between the central and lateral incisors, central incisors and canines, and lateral incisors and canines. Results: The results revealed that the frequency of SRP Class I (88.20%) was the highest, and that of SRP Class III was the lowest (0.53%). Central incisors had the highest mean labial concavity (144.5°), followed by the canines (143.9°) and lateral incisors (143.3°), and the differences were significant between any two of the tooth groups (all P |
