A dental dispenser that receives a cartridge and a blunt tip applicator for the safe and controlled extrusion and placement of dental materials such as non-injectable anesthetics.

A dispenser assembly includes a rod, a plunger and a stopper. The rod has a plunger receiving end with a clip receiving recess. The plunger has a rod receiving structure with a rod engaging clip biased to fit to the clip receiving recess of the rod for movement therewith. The stopper has a plunger receiving space that defines an aperture extending through the plunger receiving space with the rod extending through the aperture. The plunger receiving space is dimensioned such that with the rod receiving structure of the plunger located within the plunger receiving space, movement of the rod engaging clip is restricted by contact with surfaces of the plunger receiving space preventing release of the rod from the plunger.

A dispensing device for dental retraction material. The dispensing device has a cannula that forms a free front end. The free front end is formed by a first cannula portion and a second cannula portion that is arranged directly adjacent the first cannula portion. The first cannula portion has a first elongated section and a first rounded section. The second cannula portion has a second elongated section and a second rounded section. A first outer diameter (D1) of the cannula is defined on the first rounded section at the free front end, and a second outer diameter (D2) of the cannula is defined on the second rounded section at the transition between the second rounded section and the first cannula portion. The second outer diameter is greater than the first outer diameter. The first cannula portion comprises a predetermined separation structure directly adjacent the second cannula portion. The first cannula portion can be broken or cut off to provide the dispensing device with a new free front end.

A custom tool for forming a dental restoration in a mouth of a patient includes a one-piece mold body providing for a customized fit with at least one tooth of the patient, the one-piece mold body including an occlusal portion forming an occlusal surface corresponding with an occlusal surface of the tooth, a mesial proximal portion forming a mesial proximal surface corresponding with a mesial proximal surface of the tooth, and a distal proximal portion forming a distal proximal surface corresponding with a distal proximal surface of the tooth. The mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing missing tooth structure of the tooth. The occlusal portion, the mesial proximal portion, and the distal proximal portion are based on three-dimensional scan data of the mouth of the patient.
