Abstract
A model head including a jaw insert having layers of varying materials replicating the anatomical features of a human jaw. The jaw may include a mock nerve system that provides a signal to indicate the condition of the nerve. The jaw also may include a circulatory system including vessels that simulate the bleeding that occurs when a vessel in a human has been damaged.
Claims30
A dental patient model comprising:
- a jaw corresponding to a human jaw and being configured to be cut or drilled by a surgical tool to imitate a dental surgery on the jaw, the jaw including:
- a mandible having a mandibular bone layer defining a mandibular tooth socket, the mandibular bone layer including a mandibular cortical layer and a mandibular cancellous layer, a mandibular tooth coupled to the mandibular tooth socket, a mandibular gingival layer disposed over the mandibular bone layer, and a mandibular lip/buccal mucosa layer extending over the mandibular gingival layer;
- and
- a maxilla having a maxillary bone layer defining a maxillary tooth socket, the maxillary bone layer including a maxillary cortical layer and a maxillary cancellous layer, a maxillary tooth coupled to the maxillary tooth socket, a maxillary gingival layer disposed over the mandibular bone layer, and a maxillary lip/buccal mucosa layer extending over the maxillary gingival layer, wherein the mandibular lip/buccal mucosa layer and the maxillary lip/buccal mucosa layer form a jaw opening;
- and
- a nerve system having a simulated nerve associated with the jaw for corresponding to a human nerve, and an indicator operatively connected to the simulated nerve to indicate a condition of the simulated nerve.

A dental patient model, comprising:
- a jaw generally corresponding to a human jaw and being configured to be cut or drilled by a surgical tool to imitate a dental surgery on the jaw, the jaw including:
- a mandible having a mandibular bone layer defining a pair of mandibular tooth sockets, the mandibular bone layer including a mandibular cortical layer and a mandibular cancellous layer, a mandibular tooth coupled to each of the mandibular tooth sockets, a mandibular gingival layer disposed over the mandibular bone layer, and a mandibular lip/buccal mucosa layer extending over the mandibular gingival layer;
- and
- a maxilla having a maxillary bone layer defining a maxillary tooth socket, the maxillary bone layer including a maxillary cortical layer and a maxillary cancellous layer, a maxillary tooth coupled to the maxillary tooth socket, a maxillary gingival layer disposed over the mandibular bone layer, and a maxillary lip/buccal mucosa layer extending over the maxillary gingival layer, wherein the mandibular lip/buccal mucosa layer and the maxillary lip/buccal mucosa layer form a jaw opening;
- and
- a circulatory system having a vessel disposed in the mandible to generally correspond to a human blood vessel, the vessel being configured to expel fluid upon being ruptured.
3 more elements
A dental patient model comprising:
- a frame;
- a mandible coupled to the frame, the mandible including:
- a mandibular bone layer defining a mandibular tooth socket, the mandibular bone layer including a mandibular cortical layer and a mandibular cancellous layer;
- a mandibular tooth coupled to the mandibular tooth socket;
- a mandibular gingival layer disposed over the mandibular bone layer;
- and
- a mandibular lip/buccal mucosa layer extending over the mandibular gingival layer;
- and
- a maxilla coupled to the frame independent of the mandible, the maxilla including:
- a maxillary bone layer defining a maxillary tooth socket, the maxillary bone layer including a maxillary cortical layer and a maxillary cancellous layer;
- a maxillary tooth coupled to the maxillary tooth socket;
- a maxillary gingival layer disposed over the mandibular bone layer;
- and
- a maxillary lip/buccal mucosa layer extending over the maxillary gingival layer;
- wherein the mandibular lip/buccal mucosa layer and the maxillary lip/buccal mucosa layer form a jaw opening when the mandible and maxilla are coupled to the frame.
