Aim and Objective: The aim of the study was to evaluate the bone dimensions in the anterior maxilla, particularly the relationship between the alveolar crest level and the floor of the nasal fossa, and to assess how these factors correlate with age and gender using CBCT.

Materials and Methods: A total of 66 CBCT scans of patients showing anterior maxilla ranging from 18-50 years were reviewed to measure the bone dimensions in anterior maxillary teeth.

Results: In males, the palatal width of the central incisor at the crest and the lateral incisor at both the crest and 6mm from the crest were significantly greater in the 18-28 and 29-39 age groups. In females, the facial and palatal widths of the central incisor at 6mm from the crest were greater in the 29-39 age group. The distance from the crest to the nasal floor for both central and lateral incisors was higher in females aged 40-50 and in males compared to females. Males generally exhibited larger facial and palatal widths for both central and lateral incisors and a greater distance from the crest to the nasal floor.

Conclusion: This study highlights the importance of intact buccal and palatal cortical plates in enhancing implant stability and prognosis. Bone dimensions are influenced by age and gender. Further research with larger sample sizes is necessary to better understand the relationship between bone dimensions, alveolar crest level, and the nasal fossa floor across different age and gender groups.
