Problems solved by technology

Although the spread of caries appears to have stopped apparently, caries continues to spread in the long term when using this technique, so that sooner or later more radical measures are required, e.g. by means of dental fillings, onlays or crowns or roots tube treatment to replace the associated tooth hard substance
[0011] If these measures are not taken, there is a risk that carious lesions will also develop in the adjacent and possibly counter teeth involved

Embodiment Construction

[0064] exist figure 1 The germ-removing laser according to the first embodiment can be seen in the figure. The germ-removing laser 10 has a radiation source 12 which is accommodated in a base station and which is connected to the hand-held device via an optical fiber, which in particular also conducts heat. Optionally, this can also be implemented in the head region of the handheld device. The handheld device has a grip handle 14 by means of which the operator can bring the handheld device into a desired position.

[0065] In the region of the head of the hand-held device, an loading optics 16 is arranged, through which the laser beam generated by the radiation source 12 passes.

[0066] A radiation guide rod 18 is provided, which terminates in a radiation exit surface 20 .

[0067] The handheld device has a power connection 19 forming an energy source and a control unit 21 .

[0068] The radiation source is designed as an Er:YAG laser and emits laser radiation with an emi...

Abstract

A bacteria removal laser is provided, especially for removing caries bacteria from natural or prosthetic teeth, the prosthetic teeth also being treated via extraoral approach, comprising a gripping handle, a laser radiation source, an application optics having a predetermined radiation exit surface, especially a radiation guide rod through which laser radiation passes, and an energy source such asa mains connection or an accumulator. The laser emits in the wavelength range between 2200 nm and 4000 nm and is especially designed as an Er:YAG laser. The energy output averaged over time is less than 1 mJ / mm2 at the radiation exit surface.

Description

technical field [0001] The invention relates to a germ-removing laser according to the preamble of claim 1 and to a system according to claim 13 . Background technique [0002] In order to eliminate bacteria which have infected hard and / or soft tissues of humans or animals, it has long been known to use bactericidal substances. [0003] These include antibiotics in particular. In addition to resistance due to antibiotics, antibiotics are not suitable or less effective if deep tissue layers are involved. This is especially the case with hard tissue. [0004] Hard tissues mainly include human and animal teeth. Teeth are often infected with caries by cariogenic bacteria, among which Streptococcus mutans is notably included. [0005] Dental caries is usually treated by removing carious dentin with the aid of conventional dental drills. [0006] By removing the tooth's hard tissue, the tooth is damaged. Nevertheless, it is still necessary that, as a precaution, slightly mor...
