Assessment of Buccal Bone Thickness in the Anterior Maxilla: A Cone Beam Computed Tomography Study

Abstract

The aim of this study was to evaluate buccal bone thickness by cone beam computed tomography (CBCT) in patients in both genders and in different age groups. Materials and Methods: Our study included 186 anterior teeth and 62 patients with CBCT images. Buccal bone thickness was measured at the crest level, and at a distance 1 and 2 mm apical to the crest level. The t-test and ANOVA test were used in analyzing data. Results: It was found out that age and gender were not significantly associated with the buccal bone thickness of anterior teeth (p>0.05). The mean buccal bone thickness was the highest as 1.91 mm around the right canines and it was the lowest as 0.35 mm surrounding the right lateral incisor. Conclusions: Our study demonstrated that the mean buccal bone thickness increased towards the apical region for all three teeth types. CBCT precisely measures the maxillary bone thickness and may facilitate the planning process for placing implants and scheduling other types of surgeries correctly.

Thickness of the Buccal and Alveolar Bones Overlying Central Incisors: A Radiographic Iraqi Study

“…e present work revealed a progressive rise in the thickness of the buccal and alveolar bone from the crest towards the apex. Koç et al [36] and authors of other studies [37,38] concluded a coinciding view with the present finding, indicating a steady increase in thickness in an apical direction.…”

“…FOV size of CBCTs: 400 micron meters, FOV diameter: 160 mm, height: 100 mm. On CBCT, the distance between the maxillary central teeth (11,21) and the nasopalatine canal in the axial plane was calculated as the shortest distance from the apex of the maxillary central tooth to the anterior wall of the nasopalatine canal (Figure 1).…”

“…The distance between the maxillary anterior teeth (11,12,21,22) and the floor of the nasal cavity was calculated by measuring the distance from the point where the line passing through the long axis of the maxillary anterior teeth in the sagittal plane in the CBCT intersects the apex of the tooth to the closest distance drawn to the lower wall of the nasal cavity floor (Figure 2).…”

“…Buccal cortical bone thickness was calculated by measuring the distance from the anterior border of the buccal cortical bone to the long axis of the teeth at the level of the apices of the maxillary anterior teeth (11,12,21,22) (Figure 3). The root apex openings of the maxillary anterior teeth were evaluated by CBCT and those with root apex openings of more than 1 mm were classified as open apex and those with root apex openings of less than 1 mm were classified as closed apex (Figure 4).…”

“…Results: When the mean distance of the maxillary central teeth (11,21) to the nasopalatine canal was evaluated in terms of the open/closed apex status of the teeth and gender, there was no significant relationship (p>0.05). Among the maxillary anterior teeth (11,21,12,22), the root apex of tooth 22 was the farthest from the floor of the nasal cavity and the root apex of tooth 12 was the closest. It was found that the mean buccal cortical bone thickness of maxillary anterior teeth 11 and 21 with open apex was significantly higher than those with closed apex (p<0.05).…”
