摘要:

目的  探讨为防止在已有活动义齿上,因增加磁性附着体而出现的局部基托应力集中,而设计的一种抵抗局部应力装置的临床应用效果。方法  20例需增加磁性附着体的戴用活动义齿的患者,分为A、B两组,每组10例,男女各5例。A组患者应用激光焊接的方法将新设计的局部铸造基托焊接于原活动义齿基托上,B组患者采用常规自凝树脂修补义齿,两组患者在新基托上均设计有磁性附着体及义齿。结果  修复完成后全部患者均经2年随访,A组10例患者无1例出现基牙处基托折断;B组在1年和2年内各出现1例患者基托折断,另有1例出现基托隐裂。结论  应用激光焊接技术可防止因增加磁性附着体而局部应力增加出现的基托折断。

Abstract:

Objective  This study was intended to design a kind of resisting part dint of device in order to preventing the base plate break while being subjected to the dint when partial base plate dint concentrates because of the increase of the magnetic attachment to the original movable artificial teeth. Methods  Ten patients who should increase magnetic attachment was adopted in the study, and we increased a kind of new designed partial cast base plate on the original base plate using laser welding technique, then designed magnetic attachment and artificial teeth. Results  None of ten sufferers appeared the phenomenon of the break of the base plate. Conclusion  The application of the laser welding technique can prevent the break of the base plate when partial dint increase because of the increase of the magnetic attachments.
