Abstract
A dental laser apparatus and method are disclosed, wherein the laser energy is generated within a handheld handpiece. When the laser is activated, pulsed laser energy generated within the handpiece is focused by a lens, also situated within the handpiece, onto the tissues in the mouth. The laser is preferably an Erbium:YAG laser, which can cut soft tissue, hard tooth tissue such as enamel and dentin, and bone, without causing structural or pulpal damage to the teeth or other tissues in the mouth.
Claims3
A method of performing surgical procedures on tissues in an oral cavity, said tissues including, but not limited to, oral soft tissue, bone, sound dentin, intact enamel, decayed tooth material, tooth root and tooth material overlaying the tooth pulp chamber, comprising the steps of:
- positioning a hand-held device in proximity to said tissues;
- generating from within said device a pulsed Er:YAG laser beam capable of cutting said soft or hard tissues which are healthy or decayed by vaporization of the cellular contents and disruption of the cells while avoiding undesirable damage to said tissues and surrounding tissues;
- reflecting and controlling the direction of said laser beam in said device after said laser beam has been generated;
- converging said laser beam with a converging means;
- focusing said laser beam onto said tissues through an elongated removable cylinder attached to said device;
- and
- cooling said device internally.
