Smoking Factor on Classification of Alveolar Bone in Maxillary Central Incisors——CBCT Study

doi:10.13701/j.cnki.kqyxyj.2020.09.007

Abstract

Abstract: Objective: To measure the distance from the CEJ to the FBC and the thickness of the BBW in the maxillary central incisors under the influence of smoking, gender, age, and root position in the alveolar bone. Methods: The patients were divided into two groups by smokers and non-smokers. They were grouped according to gender, age, and root sagittal position in the alveolar bone (general three types: buccal type, middle type, and palatal type, and the buccal type was further classified into three subtypes: subtype Ⅰ, subtype Ⅱ, and subtype Ⅲ). BBW thickness was measured at the following points: the 4 mm apical to the cemento-enamel junction, mid-root, and apex. The distance from CEJ to FBC was also evaluated. Results: CBCT data of the maxillary central incisors of 645 patients (645 incisors, including 323 males and 322 females) were selected and analyzed. The average age of the patients was (38.09±11.78) years, male: (39.47±12.80) years; female: (36.70±10.51) years. The CEJ-FBC distance was significantly higher in the smokers (2.54±0.78) mm than that in the non-smokers (2.29±0.69) mm (P<0.05). Among the subtypes, the CEJ-FBC distance in the smokers was significantly higher than that in the non-smokers (P<0.05). Conclusion: During the immediate implantation, the height of alveolar crest and the thickness of BBW need to be accurately measured by CBCT. Smoking is an important factor to be considered.
