Abstract:
Objective:To investigate the labial(buccal)bone thickness at alveolar crest zone and alveolar crest height of the maxil-lary anterior teeth and premolars of young adults with normal occlusion.Methods:The alveolar bone of the anterior teeth and premo-lars of 67 eligible Han national young volunteers was scanned by CBCT.Then the facial bone thickness and the distance between the facial alveolar crest and Cemento-enamel Junction(CEJ)of the anterior teeth and premolars were measured and analyzed after recon-struction.Results:The distance between labial (buccal)crest and labial (buccal)CEJ of the maxillary first premolars was the lar-gest(P <0.05);there was a negative correlation between the labial(buccal)crest height and the facial alveolar bone thickness at 2 mm from CEJ toward root derection[(P <0.05),0.6 <|r|<0.8].Conclusion:The labial (buccal)crest of the first premolars was higher than that of other teeth in maxillary aesthetic zone.At alveolar crest zone,when the labial (buccal)bone was thinner,the dis-tance between labial (buccal)crest and labial (buccal)CEJ was larger,and the implant aesthetic risk is higher.
