A patient support apparatus includes a plurality of primary sensors adapted to measure different parameters used in the control of the patient support apparatus. One or more suites of secondary sensors are added to the patient support apparatus to provide data about the primary sensors. The secondary sensors may be used to detect errors in the primary sensors, to modify outputs from the primary sensors, and/or to provide usage and/or diagnostic data about the use of the patient support apparatus. The suite(s) of secondary sensors may measure parameters that affect the outputs of one or more of the primary sensors. In some embodiments, the suite(s) of secondary sensors include one or more dormant sensors that are not used on the patient support apparatus until a code modification is received from one or more external sources instructing the control system of the patient support apparatus to begin using the dormant sensor(s).

Methods for the restoration of a decayed portion of a tooth and dental matrices that may be used in the methods for the restoration of a decayed portion of a tooth are disclosed. Methods for direct elective composite additive crowning and veneering of teeth that may or may not have decay or previous restorations are also disclosed.

A custom tool for forming a dental restoration in a mouth of a patient includes a first mold body providing for a customized fit with at least one tooth of the patient. The first mold body includes a portion corresponding with at least a first surface of the tooth and an interproximal portion corresponding with an interproximal surface of the tooth, the interproximal portion being of unitary construction. The first mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing a first portion of missing tooth structure of the tooth.

A matrix adapted is for the specific tooth type, and is positioned on the tooth to covers the tooth, so that an injected curable material is encased by the matrix over the tooth. When the curable material has cured, the matrix is removed, resulting in a veneer on the tooth.
