LIGHT HARDENING APPARATUS PARTICULARLY FOR A DENTAL PRACTICE |
摘要 |
<p>A light hardening apparatus particularly suitable for effecting the hardening of dental restoration material is provided and includes twa semiconductor light sources cooperable with a light-guiding element fot guiding the light from the semiconductor light source to the dental restoration material to effect the hardening thereof. The two semiconductor light sources have an emission spectrum with at least two maximums of which one of the maximums lies at approximately 420 nm and the other maximum lies at approximately 470 nm.</p> |
