Abstract

Aim: To determine the position and angulation of maxillary central incisor with reference to alveolus for immediate implant in esthetic zone using CBCT scans. Material And Method: A total sample size of 100 Digital Imaging and Communications in Medicine (DICOM) files, that fulfilled the selection and exclusion criteria were selected retrospectively from the archives of CBCT centers via two stage sampling method for the study purpose. The scans were assessed using multiplaner reconstruction capabilities of CS 3D Imaging Software to determine thefive aspects were measured. The data obtained was subjected to Statistical Package for the Social Sciences (SPSS) software version 21. Result: The data from 100 cone beam images were included in the present study. The mean thickness of the buccal bone at the mid-root level was 1.16 ± 0.46mm and at the apical level was 3.16 ± 0.93 mm. The mean thickness of the palatal bone at the midroot level was 3.96 ± 1.11 mm and at the apical level was 8.00 ± 1.44 mm. The mean apical bone height was 8.20 ± 2.40 mm. The proportion of incisors positioned more buccally (type B) was 73%, 22%, and 5% positioned midway (type M) and more palatally (type P), respectively. Regarding the angulation, 46% were classified as type 2 (toward buccal), 24 % as type 3 (toward buccal, with the long axis anterior to the A point), and 30% were categorized as type 1 (toward palatal or parallel to the alveolus). Conclusion: Clinicians should consider the socket's three dimensions for optimal results. Cases were classified as levels I to level III based on their difficulty in achieving good results, with recommendations provided and angulation of abutments required.
