Dental impression model system, apparatus, and method
View Patent ↗Embodiments of this invention provide predictability and standardization in the field creating dental models. Embodiments of the invention are capable of accommodating multiple variations and goals of dental impressions, including but not limited to creating dental models for study models, mouth guards, night guards, whitening trays, sleep apnea/snoring devices, etc. Embodiments may incorporate single arch and dual arch impression trays, as well as base model formers and articulators, among other devices of varying shapes, dimensions, sizes and manufacturers. Embodiments of the invention use standard dimensions for accommodating various components. To adapt embodiments of the invention for multiple purposes, and to standardize the process, embodiments of the invention include a shell that allows for standardized dental models to be suspended in the shell during the process of creating dental molds, creating a reservoir for the dental mold. Embodiments allow for a trimming process where impressions are standardized by cutting away lateral excess impression material by running a knife along the lateral portion of upper and lower impression tray walls, and then by trimming away vertical excess by placing the tray into the vertical excess trimming device. In these embodiments, dental impressions and embodiments of a predetermined shell allow dental models to be created, including articulated models, in a simplified process. The present invention thus allows dental professionals to easily pour up single and double arch dental impressions, create base models, and, optionally, articulate models in fewer steps than currently available, allowing less waste, material, and use of time than traditional and current methods.

The system of claim 1 , wherein the system further comprises a shaping and cutting mold, wherein the impression tray is inserted into the shaping and cutting mold for identifying and removing excess impression material on the impression tray, the shaping and cutting mold further comprising a stem receptacle.
9. The system of claim 7 , the system further comprising a shaping and cutting mold element, where the impression tray is inserted into the shaping and cutting mold for identifying and removing excess impression material on the tray, the shaping and cutting mold further comprising a stem receptacle.
10. The system of claim 8 , wherein the impression tray further comprises at least one buccal protrusion, the shaping and cutting mold further comprises at least one female receptacle for at least one buccal protrusion on the impression tray, and the casting housing further comprises at least one female receptacle for at least one buccal protrusion on the impression tray.
11. The system of claim 1 , the casting housing further comprising at least two female receptacles for receiving at least two buccal nodules of an impression tray, and the casting housing further comprising a minimum depth from an anterior receptacle to a mouth of the reservoir of between about 40 mm and about 60 mm.
12. The system of claim 6 , wherein the receptacle is an anterior stem receptacle, the anterior stem receptacle being enclosed around a stem of the impression tray.
13. The system of claim 12 , further comprising an enclosure around a stem, wherein the enclosure further comprises at least one perforated edge.
14. The system of claim 1 , further comprising a holder for receiving and securing the casting housing in a position so as to allow time for modeling material to set and reach full hardness while retaining an accurate replication of the oral environment.
15. The system of claim 1 , wherein the casting housing holds dental impressions during the curing and hardening process, the casting housing is adapted to receive the impression tray, and the casting housing further comprises opposing inferior and superior walls having a predetermined interior aspect depth and a guide receptacle for receiving an impression tray handle.
