Objective: The dental simulator is very important for dental education at the stage of preclinical education. Training with dental simulators is expected to provide easy adaptation for students to work on patients in professional education in hospitals.
Methods: Make of the body and phantom head simulator, maxilla and mandible typodonts, lamp arms, instrument table arms, and box. Use other components hight speed, low speed, tree way syringe, valve handle, control valve, pressure valve, integral valve, connectors, air pressure matter, and power window.
Results: Vertical direction movement on the instrument table arms and arms of the operating lamp made from Spring Shock-Breaker. LED lamps as illumination are made of iron plate frame; instrument box and body made from a mixture of resin and fiber; phantom head simulator made from a mixture of resin and ceramic adhesive consists of typodont with teeth fixed with glass glue, resin teeth, and room-temperature vulcanizing (RTV) silicone gingiva can be removed, articulators in place of typodont, part maxilla of typodont is fixed on horizontal plate. Movement of head simulator forward - down and slope of the body simulator is controlled by power window.
Conclusions: The dental simulator works well as a learning tool for dental students and designed to follow the principles of dental unit technology.

Denture Base Resins From Past to New Era

In the past, the ingredients used for the denture bases were formaldehyde of vulcanite, celluloid & phenol. Around 1930's, acrylic resins were brought into dental work. There are other disadvantages of acrylics, such as residual monomer sensitivity, weak mechanical resistance, low fatigue power, fragile on contact, weak heat conductors, low stiffness, strong thermal expansion coefficient, thermal shrinkage, bad color consistency of self-curing resins, porosity, craziness, warpage, poor metal and porcelain adhesion and mechanical retaining criteria. But they are also the most commonly used products of the denture foundation to date. The aim of this literature review was to examine the established works on denture-based resources for the manufacture of full dentures and provide historical context, current status, and potential perspectives on evolving technologies to the reader. The analysis of many dentures provides an overview of the various developments in this field. The polymers, particularly the acrylic resins, are constantly changing and the materials of choice after being in this field more than 65 year.
