To evaluate whether Bio-Oss used as an adjunct to guided tissue regeneration (GTR) improves the healing of 1- or 2-wall intrabony defects as compared with GTR alone, and to examine whether impregnation of Bio-Oss with gentamicin may have an added effect.
Sixty patients, with at least one interproximal intrabony defect with probing pocket depth (PPD) > or =7 mm and radiographic evidence of an intrabony component (IC) > or =4 mm, were treated at random with either a resorbable membrane (GTR), a resorbable membrane in combination with Bio-Oss impregnated with saline (DBB-), a resorbable membrane in combination with Bio-Oss impregnated with gentamicin (DBB+), or with flap surgery (RBF).
All treatment modalities resulted in statistically significant clinical improvements after 1 year. Defects treated with GTR alone presented a probing attachment level (PAL) gain of 2.9 mm, a residual PPD (PPD12) of 4.9 mm, a radiographic bone level (RBL) gain of 3.1 mm, and a residual IC (IC12) of 2.7 mm. GTR combined with Bio-Oss did not improve the healing outcome (PAL gain: 2.5 mm; PPD12: 4.9 mm; RBL gain: 2.8 mm; IC12: 3.3 mm). Impregnation of the Bio-Oss with gentamicin 2% mg/ml resulted in clinical improvements (PAL gain: 3.8 mm; PPD12: 4.2 mm; RBL gain: 4.7 mm; IC12: 2.1 mm), superior to those of the other treatment modalities, but the difference was not statistically significant. Defects treated with only flap surgery showed the most inferior clinical response (PAL gain: 1.5 mm; PPD12: 5.1 mm; RBL gain: 1.2 mm; IC12: 4.2 mm) of all groups.
The results failed to demonstrate an added effect of Bio-Oss implantation in combination with GTR on the healing of deep interproximal 1- or 2-wall, or combined 1- and 2-wall intrabony defects compared with GTR alone. Local application of gentamicin, on the other hand, improved the treatment outcome but not to an extent that it was statistically significant.
评估与单纯引导组织再生术(GTR)相比,使用Bio-Oss作为引导组织再生术的辅助材料是否能改善1壁或2壁骨内缺损的愈合情况,并研究庆大霉素浸渍的Bio-Oss是否具有额外效果。
60例患者,至少有一处邻间骨内缺损,探诊袋深度(PPD)≥7 mm且有骨内成分(IC)≥4 mm的影像学证据,随机接受以下治疗:可吸收膜(GTR)、可吸收膜联合用生理盐水浸渍的Bio-Oss(DBB-)、可吸收膜联合用庆大霉素浸渍的Bio-Oss(DBB+)或翻瓣手术(RBF)。
1年后,所有治疗方式均在临床上有统计学意义的显著改善。单纯GTR治疗的缺损处探诊附着水平(PAL)增加2.9 mm,残余PPD(PPD12)为4.9 mm,影像学骨水平(RBL)增加3.1 mm,残余IC(IC12)为2.7 mm。GTR联合Bio-Oss并未改善愈合效果(PAL增加:2.5 mm;PPD12:4.9 mm;RBL增加:2.8 mm;IC12:3.3 mm)。用2%mg/ml庆大霉素浸渍Bio-Oss在临床上有改善(PAL增加:3.8 mm;PPD12:4.2 mm;RBL增加:4.7 mm;IC12:2.1 mm),优于其他治疗方式,但差异无统计学意义。仅接受翻瓣手术治疗的缺损在所有组中临床反应最差(PAL增加:1.5 mm;PPD12:5.1 mm;RBL增加:1.2 mm;IC12:4.2 mm)。
结果未能证明与单纯GTR相比,Bio-Oss植入联合GTR对深部邻间1壁或2壁或联合1壁和2壁骨内缺损的愈合有额外效果。另一方面,局部应用庆大霉素改善了治疗结果,但未达到具有统计学意义的程度。
