Abstract
A light curing dental system comprising a light emitting tray that precisely distributes an optimal amount of curing light energy to internal, external and extra oral portions of the dental arch to cure a dental material. The light curing dental system generally includes a light source, a light emitting dental tray, an activation module and a photocurable dental material.
Claims14
A dental tray comprising:
- a body having a channel for receiving a quantity of photocurable dental material;
- at least one light source housed in said body, the at least one light source being mounted on a flexible printed circuit board having a shape that substantially conforms to a shape of the dental tray;
- and
- at least one battery source electrically connected to said light source and coupled to said body,
- wherein the channel has mechanical retaining features at a bottom of the dental tray that are capable of retaining a majority of the photocurable dental material upon curing within the dental tray,
- wherein said light source extends along said body and is oriented toward the internal and external portion of a dental arch to allow for adequate curing of dental material in the body and dental material that overflows outside the channel,
- wherein the at least one light source is a light emitting diode or a flexible light emitting diode strip, and
- wherein the dental tray has clear areas selectively located on sidewall edges that permit light towards the directions of the clear areas to escape and cure the photocurable material that overflows tray borders.
