[Application of the laser welding to preventing the break of the base plate caused by the increase of magnetic attachments].
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.


CONCLUSIONS
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.
