1、結(jié)論應(yīng)用不同修復(fù)材料治療牙槽突裂，通過影像學(xué)和組織學(xué)檢測(cè)，觀察上頜骨發(fā)育情況及局部成骨能力，相互對(duì)比，證實(shí)各種材料植入牙槽突裂隙內(nèi)，（1）對(duì)上頜骨發(fā)育有不同程度的影響：其中自體髂骨影響最小，脫鈣骨次之，骨水泥影響最大；（2）從成骨能力上看，從好到差依次為：髂骨組，脫鈣骨組，骨水泥組，髂骨組明顯優(yōu)于其他各組。關(guān)鍵詞自體髂骨脫鈣骨骨水泥CT三維重建牙槽突裂2TheexperimentalstudyonbonereconstructionofalveolarcleftbydifferentmaterialsAbstractObject:Establis
