Abstract:
Objective To investigate labial and lingual alveolar bone plate thickness of the mandibular anterior teeth by using cone-beam computed tomography (CBCT),in order to provide a reference for immediate implantation.Methods 132 individuals with normal occlusion were examined with CBCT,and their mandibular anterior teeth were analyzed.The labial and lingual alveolar bone plate thickness at the level of the apical,1/4 of the apical,1/2 of the middle and 1/4 of the cervical were measured.The differences of the thickness were compared among the side and gender.Results There were no significant differences between the left and right sides. Except on the 1/4 of the cervical,the thickness of lingual bone plate was thicker than that of labial bone plate.The frequency of the thickness of the labial bone larger than 2 mm on the 1/4 of the cervical of the center incisor,lateral incisor,and canine were 0,0 and 1.5 1%,respectively,and on 1/4 of the middle were 0.76%,1.44% and 3.79%,respectively.The lingual bone plate thickness showed significant difference between genders.Conclusion Reference values of alveolar bone plate thickness in anterior teeth of normal occlusion were established by using CBCT,which can provide clinical instruction for immediate implant.
