【摘要】：目的:通过随机对照试验评价上颌窦外提升不植骨术的临床效果以及从影像学上评估其成骨效果。方法:纳入需接受上颌窦外提升治疗的患者20例,随机分为两组:1)实验组10例接受上颌窦外提升不植骨同期种植术;2)对照组10例接受上颌窦外提升植入羟基磷灰石同期种植术。术后定期随访进行种植体成功率,影像学,种植稳定系数(Implant stability quotient,ISQ)评估。结果:随访期内两组均未出现种植体松动脱落。术后即刻实验组近中剩余牙槽骨高度(residual bone height,RBH)为(4.50±0.21)mm,3个月上升至(6.88±0.85)mm(P0.05),6个月为(7.42±0.66)mm,至12个月时稳定于(7.55±0.55)mm:对照组近中术后即刻RBH为(11.29±0.64)mm,3个月下降至(10.11±0.62)mm,6个月为(9.51±0.39)mm(P0.05),到12个月时稳定在(9.59±0.39)mm。两组远中RBH变化与近中相似,各时间点对照组RBH均高于实验组(P0.05)。二期手术时,实验组ISQ由术后即刻(53.92±7.31)上升至(64.77±9.22),对照组由(56.23±8.05)上升至(67.29±8.34)(P0.05)。结论:上颌窦外提升不植骨术短期内能获得较理想的临床效果以及一定的成骨效果。
[Abstract]:Objective: to evaluate the clinical effect of extranasal maxillary sinus lifting without bone graft and evaluate its osteogenic effect by randomized controlled trial. Methods: twenty patients were randomly divided into two groups: the experimental group (n = 10) and the control group (n = 10) received simultaneous implantation of hydroxyapatite. The success rate of implant, imaging and Implant stability quotient factor (ISQ) were evaluated regularly after operation. Results: during the follow-up period, there was no loosening and falling off of implants in both groups. Immediately after operation, the (residual bone height of the proximal and middle alveolar bone in the experimental group was (4.50 卤0.21) mm, increased to (6.88 卤0.85) mm (P0.05) in 3 months, (7.42 卤0.66) mm in 6 months, and stabilized at (7.55 卤0.55) mm at 12 months. It was (11.29 卤0.64) mm immediately after operation in the control group, decreased to (10.11 卤0.62) mm in 3 months, (9.51 卤0.39) mm in 6 months, and (9.59 卤0.39) mm in 12 months. The changes of RBH in the distal of the two groups were similar to those in the near middle, and the RBH in the control group was higher than that in the experimental group at each time point (P0.05). The ISQ of the experimental group increased from (53.92 卤7.31) to (64.77 卤9.22) at the second stage of operation, and that of the control group increased from (56.23 卤8.05) to (67.29 卤8.34) (P0.05). Conclusion: the clinical effect and osteogenic effect can be obtained in short term after extranasal lifting without bone grafting.
