Evaluation of maxillary bone in the anterior esthetic zone for immediate implant placement: An observational CBCT study

Abstract

Aim and objective: This study provides a guideline for immediate implant placement in the anterior esthetic zone based on the observed bone morphology in the North Indian population. Materials and methods: Cone-beam computed tomography (CBCT) images of maxillary anterior teeth of 100 patients (total sample size: 600 teeth) in the North Indian population were analyzed for their relation to the alveolus in the sagittal plane following Kan’s classification. Results: Sixty-three percent of the study sample were classified as Kan’s Class I sagittal root position (SRP), 10.66% was Class II, and 26.33% was Class IV. Class III SRP was not observed in the study sample. Conclusion: Class I is the most common sagittal root position observed in the North Indian population. This study emphasizes the importance of CBCT for predictable treatment planning in the esthetic zone. Clinical significance: For achieving esthetic results in the maxillary anterior region accurate three-dimensional imaging of hard tissue structure is a prerequisite.
