上颌第一磨牙区腭侧骨板的锥形束CT测量结果及其临床意义
Measurement of the maxillary first molar area palatal side bone plate by cone-beam computer tomography and its clinical significance
摘要
Abstract
Objective Collected cone-beam computer tomography(CBCT) data,to provide anatomia basis for clinical application of implants in the maxillary first molar area palatal side bone by measuring the maxillary first molar area alveolar bone height and width along the vertical direction and the palatal transverse plate.Methods A total of 169 patients evaluated by CBCT scans were included in the date bank of Guangdong Provincial Stomatological Hospital were analyzed.Both height and width of the alveolar bone in the edentulous area of maxillary first molars and that of the alveolar bone of maxillary first molars were repeatedly measured three times every two weeks to get mean value.Results Mean alveolar bone height and width of the first molar was respectively 9.33 mm and 13.28 mm.Mean alveolar bone height and width of 90 patients with first molar loss was respectively 6.99 mm and 8.93 mm.There were 28 patients with less than 5.0 mm height of alveolar bone.With 3.5 mm,4.0 mm and 4.5 mm respectively defined as the minimum width,compared with vertical direction,more bone mass were respectively obtained in 10 patients(35.7％),9 patients(32.1％) and 6 patients(21.4％) when measuring in lateral direction of the palate.Conclusion With the maxillary first molar lost,more bone mass can be obtained in some patients along the lateral direction of the palate,which could provide basis for clinical application of implants in the maxillary first molar area palatal side bone.关键词
