目的

探讨微创拔牙技术和传统拔牙技术的不同。

方法

对677 例患者采用随机分组对照研究，一组采用传统拔牙术（342 例），另一组采用微创拔牙技术（335 例），比较拔牙用时断根率、牙槽窝完整率、牙龈撕裂率、干槽症发生率及患者的接受程度。

结果

微创技术用时长于传统技术，但在各项并发症指标均优于传统技术，除干槽症发生率外，各项指标均有统计学意义。

结论

微创技术能够有效降低并发症的发生，减少患者恐惧，一定程度达到舒适化拔牙。

Objective

To investigate the application of minimal invasive technique， and compared with the traditional technique.

Methods

The patients who have to extract tooth were recruit and randomly divided into minimal invasive group and traditional technique groups. The time of operation， incidence rate of root broken， alveolus intact rate， gingival lacerated rate， incidence rate of dry socket and fear of patient were compared and analyzed.

Results

The operation time used in minimal invasive group is longer than that in the traditional group， there is no statistical difference in the incidence rate of dry socket， while the other factors shows statistical difference.

Conclusion

Minimal invasive technique could reduce the incidence of complications； and make the operation more comfortable， it is worth to popularize minimal invasive tooth extraction.
