Evaluation of mandibular first molar teeth in the context of immediate implant placement using Cone Beam Computed Tomography

Abstract

Objective: During the immediate dental implant (IMI) procedure in the mandibular posterior region, some limitations caused by anatomical structures that may affect the success of implant treatment and increase the risk of complications may be encountered. Socket size, distance from root apices to the inferior alveolar canal (IAC), and lingual concavity are some of the critical conditions. This study aimed to examine the alveolar bone of mandibular first molars using cone beam computed tomography (CBCT) and to evaluate its prevalence on a subpopulation basis. Material and Methods: A total of 153 mandibular first molar teeth in 100 patients who met the evaluation criteria were evaluated for cross-sectional classification of the alveolar bone, distance from root apices to IAC, and socket size using CBCT scans. Results: In this study, which included 42 females and 58 males, the age range was 19-70 years (38.13±13.74 years). Of the 153 mandibular first molars analyzed, 53.6% were on the left, while 46.4% were on the right. The distances from the apices of the roots to the IAC were the least in females (p<0.05) and U-type ridges. It was also found that this distance was positively correlated with age. The mean crestal socket width measured in the current study was suitable for choosing a dental implant with an appropriate diameter for IMI surgery. Conclusion: Cross-sectional analysis of the relevant regions before surgery is important for IMI placement. This will allow clinicians to take precautions against possible complications.
