摘要:

背景:目前关于种植体即刻负重或延期负重方案的选择尚存在一定的争议。
目的:探讨基于种植体稳定系数值的Bego种植体负重方案选择,并分析影响种植体稳定性的相关因素。
方法:选择植入后种植体稳定系数值≥50的单个Bego种植体患者62例,共74颗种植体。随机分为试验组31例36颗种植体,予以种植后即刻负重;对照组31例38颗种植体,予以延期负重。比较两组Bego种植体负重后1,2,3,4,6,8,12周种植体稳定系数值,分析影响Bego种植体稳定性的相关因素。
结果与结论:试验组即刻负重的最低稳定系数出现在负重后第二三周,对照组延期负重的最低稳定系数出现在负重后第三四周。两组Bego种植体负重后1,2,3,4,6,8,12周种植体稳定系数值差异均无显著性意义(P > 0.05)。经回归分析,患者年龄、骨质类型和种植体长度与Bego种植体稳定性呈正相关,口腔卫生情况与Bego种植体稳定性呈负相关。说明Osstell测量种植体稳定系数值≥50的单个Bego种植体采用即刻负重与延期负重对种植体具有相似的稳定性,临床可以根据患者自身状况,在Osstell测量种植体稳定系数值的指导下,选择个体化的Bego种植体负重方案。

Abstract:

BACKGROUND: There are some controversies on the choice of immediate or delayed weight-bearing schemes of implants.
OBJECTIVE: To explore the weight bearing scheme for Bego implants based on implant stability quotient (ISQ) measured by Osstell, and to analyze the factors which influence implants’ stability.
METHODS: Seventy-four single Bego implants with ISQ ≥ 50 in 62 patients were selected and randomly divided into test group (36 single Bego implants in 31 patients) and control group (38 single Bego implants in 31 patients). Patients in the test group were given immediate loading, and patients in control group were given delayed loading. Two groups’ ISQ of Bego implants after loading (1, 2, 3, 4, 6, 8 and 12 weeks) were compared, and factors which influence implants’ stability were analyzed.
RESULTS AND CONCLUSION: The lowest ISQ for immediate loading of the test group appeared in 2-3 weeks after loading, and that of the control group appeared in 3-4 weeks. There was no statistical difference between two groups on ISQ of Bego implants after bearing (1, 2, 3, 4, 6, 8 and 12 weeks) (P > 0.05). Multiple regression analysis showed that the factors including age, types of osseous substance and implant length were positively related with stability of Bego implants, yet oral hygiene was negatively related with stability of Bego implants. Immediate loading and delayed loading have similar stability to single Bego implants with ISQ ≥ 50 measured by Osstell, so individualized weight bearing scheme may be selected according to patient’s own condition under the guidance of Osstell, further to improve implants’ success rate after loading.
