目的

初步探讨微型支抗种植体周围组织炎症的发病率及相关因素,为今后种植体的设计及临床维护工作提供参考。

方法

观察分析128 枚微型支抗种植体的临床使用情况,定期监测菌斑指数(PLI)、改良龈沟出血指数(mBI)和种植体周探诊深度(PD)等临床指标,并对检测结果进行统计学分析。

结果

128 枚微螺钉种植体中7 枚PD 大于或等于4 mm,5 枚支抗种植体脱落。 微螺钉种植体组的PLI、mBI 及PD 等临床指征均高于对照天然牙,差异均有统计学意义(P<0.05),但种植体组内在不同时期之间检查指数比较差异无统计学意义(P>0.05)。 出现黏膜炎的种植体的PLI、PD 普遍高于健康种植体,差异有统计学意义(P<0.05),且有随炎症程度的加重而升高的趋势。

结论

大部分微型支抗种植体周围软组织均出现轻微炎症,在考察支抗种植体颈部软组织健康状况时,应综合采用mBI、PLI 与PD 这3 个临床指征。

Objective

To investigate the incidence and correlation factor of periimplantitis around micro-implant.

Methods

The clinical effects of 128 micro-implants were evaluated by regular follow-up at 1, 3, 6, and 9 months. Clinical examinations including plaque index (PLI), modification sulcus bleeding index (mBI), probing depth (PD) were made for each micro-implant. The results were statistically analyzed and evaluated.

Results

Seven microimplants among 128 showed PD more than 4 mm, 5 were lost. The PLI, mBI and PD of the micro-implants were higher than those of the control teeth (P<0.05), but the clinical index of the micro-implants in different follow-up times were not significantly different (P>0.05). The PLI and PD around the micro-implants with peri-mucositis were higher compared with the healthy implants (P<0.05). The PLI and PD increased with the severity degree of inflammation.

Conclusions

Light inflammation can occur at the surrounding soft tissue in all micro-implants.Clinical index such as mBI, PLI and PD should be generally taken into account for the evaluation of the health status of the surrounding soft tissue of micro-implants.
