Study of the retentive characteristics for SynCone conical crown immediate loading system

目的:实验室研究SynCone套筒冠式即刻负重种植系统的固位特性。方法:选取锥度为4度和6度的SynCone直基台套筒冠系统各6个作为研究对象,采用Life-test仪器,在20N就位力的条件下重复测量其固位力5000次,分析其固位力的大小及其持久性。结果:在20N就位力条件下,4度锥度的SynCone套筒冠系统的固位力均数为8.01N,6度锥度的套筒冠系统的固位力均数为7.23N;两种锥度套筒冠的固位力无显著性差异,固位力持久。结论:SynCone套筒冠即刻负重种植系统可为其上的覆盖义齿提供适宜持久的固位力。

To study of the retentive characteristics for SynCone conical crown immediate loading system. Methods：6 SynCone conical crowns with 4-degree angle and 6 SynCone conical crowns with 6-degree angle were tested in vitro for a total of 5000 insertion-separation cycles to investigate their retentive characteristics under 20N insertion force. Their retentive characteristics were analyzed. Results： Under 20 N insertion force, the retentive force of SynCone conical crown system was between 5 and 10 N. The retentive force kept almost constant during the entire testing cycles. Conclusion： the SynCone conical crown system can provide adequate and constant retentive force to retain implantsupported overdentures.
