Abstract
The present invention provides an apparatus for manufacturing a dental restoration. The apparatus includes a first laser module, a powder supplying nozzle, a second laser module, a dust cleaning device and an air bearing device for holding the dental restoration. The second laser module includes a plurality of laser sources, and the laser sources disposed circumferentially around the first laser module, in which each laser source is equally spaced apart from one another. The present invention further provides a method for manufacturing the dental restoration, in which the method can be applied to a laser cladding process or a laser milling process.
Claims4
An apparatus for manufacturing dental restoration, comprising:
- a first laser module, comprising a first laser source;
- a powder supplying nozzle, comprising a channel and at least one powder injection passage both of which are disposed in the powder supplying nozzle, wherein the at least one powder injection passage is adjacent to the channel, and the channel is configured such that a laser beam emitted by the first laser source passes through the channel;
- a second laser module, comprising a plurality of second laser sources disposed circumferentially around an outer sidewall of the powder supplying nozzle, wherein each second laser source is equally spaced apart from one another;
- a dust cleaning device, comprising:
- a dust suction hood where the first laser module, the powder supplying nozzle and the second laser module are disposed;
- and
- an evacuation device connected to the dust suction hood;
- and
- an air bearing device for holding a dental restoration, wherein the first laser module and the second laser module are disposed over the air bearing device.
