Abstract
Abstract A simulated dentition for use by a dental student when studying and experimentally learning painstaking skills, dental practice, and chairside procedures comprising: an innovation expressly fabricated for placement and temporary retention within the confines of the oral cavity of a live in-the-chair student impersonating an actual patient. Made of non-deleterious material and structured to provide precisely contoured and compatible components upon which dental operative procedures can be capably evaluated and safely executed by the dental student. The first named student becomes a ''''dentist'''' and a second in-the-chair student provides the ''''patient.'''' The essence of the concept pertains to the unique intra-oral dentition.

A simulated dentition for use in studying and learning dental operative practices insertable into a normal oral cavity of a living human having natural teeth comprising a body portion having generally channel shaped side portions, said side portions being offset from the body portion a distance sufficient to receive and overlie the gums and natural teeth, said body portion overlying and protecting the area of the oral cavity between the gums and said side portions overlying and protecting the natural teeth and gums when disposed in the human oral cavity, said side portions having teeth fixedly disposed on the external surface thereof, said body portion and side portions having a liner of impression material with indentations for receiving the natural teeth to secure the simulated dentition to the natural teeth in the oral cavity, said body portion, side portions and teeth being constructed of material resistant to penetration by intra-oral dental implements, tool and the like, thereby enabling intra-oral activities to be performed on the simulated dentition while disposed in a normal oral cavity of a living human without injury to the area of the oral cavity covered thereby with all other areas of the oral cavity being natural thereby enabling the intra-oral activity to be repeatedly conducted under substantially normal conditions.
