Abstract：AIM: To investigate facial alveolar bone thickness overlying healthy maxillary anterior teeth measured by CBCT. METHODS:CBCT data from 300 subjects with healthy maxillary anterior teeth were included. The labial alveolar bone thickness of maxillary anterior teeth at the levels of 1 mm apical to bone crest(T1),mid-root (T2) and apical point(T3) was respectively measured using software. RESULTS:For central incisors T1,T2 and T3 was 0. 95 ± 0. 31 mm, 1. 00 ± 0. 37 mm and 1. 53 ± 0. 78 mm (T1 vs T3, P < 0. 05); for lateral incisors 0.87 ± 0.33 mm,0.71 ± 0.46 mm and 1.30 ± 0.90 mm (P<0.05); for canine 0.97 ± 0.41 mm,0.60 ± 0.51 mm and 1.05 ± 0.86 mm(P<0.05),respectively. The percent occurrence of the thickness≥2 mm at T1,T2 and T3 for central incisors was 0.8%,1.8% and 26.2%, for lateral incisors 0,0.8% and 18.7%, for canine 1.2%,1.0% and 14.8%,respectively. There was no significant difference about the thickness between gender,except at T2 of the central incisors. There was no significant difference of thickness of the maxillary anterior teeth among different age,ex-cept at T3 and T2 of lateral incisors. CONCLUSION:The thin labial alveolar bone overlying healthy maxillary anteri-or teeth is prevalent weak in the people with normal occlusion.
