Abstract
The invention includes a system and method for making injection molded dental appliance apparatuses having an injector module removably attached to a dental flask, a press and a controlled compression apparatus, wherein the press and compression apparatus introduce pressure into the dental flask and the injector module, which pressure may or may not be maintained during curing of the appliance. The invention also includes a system for dispensing dental appliance chemicals having at least one chemical dispensing apparatus and a mixing container; whereby a separate dispensing apparatus is used for each chemical and the chemicals are dispensed and mixed in the same container.
Claims12
A system for mg injection molded dental appliance apparatuses using a curable material, the system comprising:
- a dental flask;
- a pressure cap including spring mean and pressure retaining means, the spring means adapted to removably engage the pressure cap;
- a metal injector module adapted to sealably receive the pressure cap and removably attached to the dental flask, the metal injector including an injection cylinder, a piston and a spring mechanism, the injection cylinder adapted to removably receive the piston;
- a press adapted to removably apply a force to the pressure cap;
- and
- compression means;
- wherein the press and the compression means introduce pressure into the dental flask;
- which the dental flask with the attached metal injector is adapted to be positioned in a microwave oven such that curing of the curable material in the dental flask is effected;
- wherein the pressure cap provides continuous pressure to the dental flask during the curing;
- and
- wherein the metal injector provides continuous injection of the curable material to the dental flask during the curing.
A system for making injection molded dental appliance apparatuses comprising:
- a dental flask;
- a metal injector module removably attached to the dental flask;
- wherein the injector module further comprises:
- an injector cylinder;
- piston;
- a spring mechanism;
- a pressure cap having a spring mechanism, the spring means adapted to removably engage the pressure cap, the pressure cap adapted to sealably attach to the injector module;
- and
- a pressure retaining means;
- wherein the pressure retaining means is adapted to removably engage the pressure cap and wherein the piston is adapted to be removably inserted into the injection cylinder;
- wherein the pressure cap is adapted to removably receive a force from a compression means;
- and
- wherein the dental flask with the attached metal injector is adapted to be positioned in a microwave oven.
