Abstract

Claims (18)

1 . A heating device for heating a dental material, the heating device comprising a body and a socket, wherein the socket is removably received within the body and comprising a socket wall that forms a receptacle for positioning a container for the dental material therein, wherein the body comprises a light source for emitting light toward the socket wall in a direction toward the receptacle, wherein the light source comprises a plurality of light emitting diodes (LEDs) configured for emitting infrared light, and wherein the socket wall is at least partially transmissive for infrared light, wherein infrared light being defined by light that exhibits a wavelength within a wavelength range of between 800 nm to 1500 nm; and wherein the socket wall comprises a reflective layer for reflecting light and thermal radiation in a direction toward the receptacle.

2 . The heating device of claim 1 , wherein the receptacle is formed in that the socket wall forms a through-passage extending through the socket along a longitudinal insertion axis.

3 . The heating device of claim 1 , wherein the reflective layer delimits the receptacle.

4 . The heating device of claim 1 , wherein the reflective layer comprises infrared transmissive portions and infrared blocking portions.

5 . The heating device of claim 4 , wherein the infrared transmissive portions exhibit a transmittance for infrared light of at least 80%, and wherein the infrared blocking portions exhibit a transmittance for infrared light of less than 10%.

6 . The heating device of claim 4 , wherein the socket wall further comprising an infrared transmissive layer covering the infrared transmissive portions and the infrared blocking portions.

7 . The heating device of claim 4 , wherein the (LEDs) are configured for emitting light within a wavelength range of 800 nm to 1400 nm.

8 . The heating device of claim 7 , wherein the LEDs are arranged on a circumference around the insertion axis, and being oriented for emitting light toward the insertion axis.

9 . The heating device of claim 7 , wherein the LEDs are arranged outside the socket.

10 . The heating device of claim 7 , wherein each of the LEDs is arranged for emitting light through one of the infrared transmissive portions.

11 . The heating device of claim 1 , comprising a rechargeable battery for powering the light source.

12 . The heating device of claim 11 , further comprising a charging coil for wireless charging of the battery.

13 . The heating device of claim 12 , wherein the heating device further comprises a charging pad having a second charging coil on which the body of the heating device can be placed for inductive charging of the battery.

14 . The heating device of claim 11 , further comprising a docking station to which the body of the heating device can be docked, wherein the docking station provides an electrical connection between the docking station and the battery for charging of the battery.

15 . A system, comprising the heating device of claim 1 and a capsule containing the dental material, wherein the capsule comprises a body forming a chamber for the dental material, a dispensing nozzle connected to the chamber for dispensing the dental material and a piston arranged in the chamber for urging the dental material toward the dispensing nozzle.

16 . The system of claim 15 , further comprising a dispensing gun for retaining the capsule therein and for advancing the piston of the capsule.

17 . The system of claim 15 , wherein the dental material is contained in a capsule.

18 . The system of claim 15 , wherein the dental material is a dental composite filling material.
