Problems solved by technology

However, this can lead to heating of the dental material and cause postoperative morbidity in the patient
Additionally, this can cause the dental material to harden excessively and become brittle
Although dental practitioners are often skilled at controlling dental lighting to properly harden even larger fillings, there is a tradeoff between filling quality and patient comfort on the one hand and the way the dental practitioner handles dental lighting on the other. There is a relatively high degree of dependence

Embodiment Construction

[0046] figure 1 An exemplary dental light irradiation device 1 is shown. The device 1 has a housing 3 and a light guide 2 with a light output 4 . The dental light irradiation device 1 of this example is removably placed in the base 5 . The device 1 is powered by batteries and can therefore be detached from the base 5 without the need for a permanent wired connection between the device 1 and the base 5 . The base 5 has a power source for charging the device 1 when the device is placed in the base 5 . Such a power supply may comprise physical electrical contacts for contacting corresponding contacts of the device 1 , or inductive couplers for coupling with corresponding inductive couplers in the device 1 . The exemplary dental light irradiation device 1 also has two buttons, an on / off button 10 and a selector button 11 . The selector button 11 is generally used to preselect the period of time the device will operate after being turned on via the on / off button 10 . Thus, the...

Abstract

A dental light irradiation device is adapted to emit blue light. The device has a light source, means for collimating light emitted from the light source, and a light guide. The light collimating means comprising: a plano-convex lens oriented with the planar side toward the light source, and a reflector formed by a hollow ring-shaped structure having an inner conical and reflective surface. The reflector is arranged such that its inner cross-section widens toward the lens and extends over the entire distance between the planar side of the lens and the light source. The light source being positioned substantially at the effective focal length of the lens, and the light guide having an input side for receiving light emitted from the light source and an output side for the light.

Description

technical field [0001] The present invention relates to a dental light irradiation device, and in particular to a dental light irradiation device adapted to emit light in a working area with a light intensity distribution within a predetermined minimization range. Background technique [0002] Light-curing or light-hardening materials are widely used in dentistry for restoration of teeth, for example for filling cavities in teeth. Such materials are often manufactured to provide an optical signature similar to that of natural teeth, which makes these materials a preferred replacement for, for example, unsightly amalgam materials. [0003] Photohardenable materials often include a polymerizable matrix material and a filler material including a colorant, and may initially be substantially soft or flowable, enabling application in a desired shape to a desired location. For example, to restore a tooth, dental material may be filled into cavities and shaped so that the restored ...
