Occlusal contact between upper and lower virtual three-dimensional teeth of a patient when the upper and lower arches are in an occlused condition are determined and displayed to the user on a user interface of a general purpose computing device. Various techniques for determining occlusal contacts are described. The areas where occlusal contact occurs is displayed on the user interface in a readily perceptible manner, such as by showing the occlusal contacts in green. If the proposed set-up would result in a interpenetration of teeth in opposing arches, such locations of interpenetration are illustrated in a contrasting color or shading (e.g., red). The ability to calculate distances and display occlusal contacts in a proposed set-up assists the user in planning treatment for the patient. The process can be extended to interproximal contact detection as well. The concepts also apply to dental prosthetics, such as crowns, fillings and dentures.

An electrical connector assembly for use in environmentally challenging locations. The electrical connector assembly comprises a receptacle connector member, a plug connector member and a coupling nut that interface to provide dual radial seals so as to define dual contaminant barriers. The dual radial seals substantially eliminate the possibility of particulate as well as moisture and water intrusion. Each connector member is individually potted to a wire to eliminate the potential for water wicking up the wire while transferring the wire pull strength to the connector member. The electrical connector can include a security seal to provide visual indication of any tampering with the electrical connector assembly. Each connector member can include a protective cover allowing the connector members to be stored for extended periods of time without degradation.
