Abstract
A system enabling precise control of dental wax application by fine temperature control includes a PID thermostatic controller, at least one cartridge heater and a temperature sensor. The cartridge heaters are embedded in a heater block containing heating that transfers heat to a barrel of a wax applicator when the barrel is intermittently placed into a heating chamber of the block.
Claims4
A dental wax application system for precise control of wax flow and for prolonging the useful life of wax comprising:
