Embodiment Construction

[0064] Referring now to the attached drawings, especially to the figure 1 , figure 2 with Figure 3A , in one embodiment of the present invention, the dental instrument 10 may be used in dental procedures, such as gingival retraction or restorative surgery, for dispensing dental material into a patient's mouth. For this, in figure 1 In the illustrated embodiment, the instrument 10 includes a handheld device, also referred to as a handpiece 12 , which is coupled to a cartridge or cartridge 14 via an adapter 16 . Adapter 16 creates a mechanical connection between handpiece 12 and prime 14, as described in detail below. According to an embodiment of the present invention, the adapter 16 allows for the use of a variety of filling configurations, as the filling configurations can vary at least due to the amount used and the dental material. The dental instrument 10 may be used to dispense a dental material 18 in the vicinity of a tooth T (FIG. 3B), as is known from restorati...

Abstract

An adapter for coupling a priming to a dental handpiece including a plunger. The loading holds dental material. The adapter includes a coupling portion defining an opening for attaching the adapter to the filler and attaching the adapter to the dental handpiece. The plug portion extends through an opening and engages the piston. A breakable tab connects the coupling portion and the plug portion and breaks off during dispensing of the material. Then, the plug portion moves relative to the coupling portion. A tip for use with a dental handpiece includes a housing defining a chamber. A needle extends from the housing and defines a lumen having an opening through which dental material is dispensed. The plug slides within the chamber to push dental material through the lumen, and includes ribs that seal the plug relative to the chamber during sliding movement of the plug.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 026,961, filed July 21, 2014, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to adapters for dental treatment, and more particularly to adapters, tip pieces and dental assemblies for dispensing dental material. Background technique [0004] In dental technology, dental surgery can include gingival retraction, in which a space is opened around the prepared margin. Sufficient gingival retraction must be achieved in all subgingival areas to ensure that dental impression material or digital scans reach at least the margin of the preparation. Different retraction methods can include the use of retraction cords, laser or electrosurgery, or retraction creams. During gingival retraction procedures with gingival paste, the paste is dispensed or injected into ...
