摘　　要：目的观察Bio-oss及Bio-oss骨胶原填充于拔牙后新鲜牙槽窝对于早期牙槽嵴形态改建的影响。方法24枚上、下颌后牙拔除后同时给予不同处理,其中拔牙窝填充混合富血小板血浆的Bio-oss(BP组)7例;拔牙窝填充Bio-oss骨胶原(BC组)7例;拔牙窝自然愈合(C组)10例。牙齿拔除后1～2周、9～12周两次复诊,观察牙龈愈合差异,取模型,测量缺牙处牙槽嵴宽度,行不同组间及组内的前后比较。结果各组牙槽嵴宽度前后模型测量存在差异(P<0.05);BP组与BC组,BP组与C组间前后差值存在显著差异(P<0.05)。结论Bio-oss植入减轻了拔牙后牙槽嵴的吸收,Bio-oss骨胶原对于拔牙窝嵴顶处牙龈上皮的爬行覆盖具有促进作用。Objective To investigate the effect of Bio-oss and Bio-oss Collagen on extraction socket in early healing phase.Methods Eighteen patients for premolar or molar extraction were randomly selected to receive either extraction alone(C group),or ridge preservation using Bio-oss mixed with PRP(BP group) or Bio-oss Collagen(BC group).Clinical evaluation and study cast measurements of the extraction site were carried out at 1～2 weeks and then at 9～12 weeks after socket healing.Results In each pair of the groups,the...
