To evaluate the clinical effect of laser-welded crowns and bridges.
Two hundred defective crowns and bridges were welded by using Heraplus laser welding machine, and then restored by porcelain.
After being welded ,those defective crowns and bridges of different materials fit well and their marginal areas were also satisfactory. During the follow up period of one year, no fractured porcelain and crack were found at welding spots.
The technology of laser welding has no direct effect on welding spots between metal and porcelain and could be used to deal with the usual problems of the crowns and bridges.
评估激光焊接冠桥的临床效果。
使用赫拉普拉斯激光焊接机对200个有缺陷的冠桥进行焊接，然后用瓷修复。
焊接后的不同材料的有缺陷冠桥贴合良好，边缘区域也令人满意。在一年的随访期内，焊接部位未发现瓷裂和裂纹。
激光焊接技术对金属与瓷之间的焊接部位无直接影响，可用于处理冠桥的常见问题。
