Survey of partial removable dental prosthesis (partial RDP) types in a distinct patient population.

Statement Of Problem: Current demographic information on the number and types of removable partial dentures is lacking in the prosthodontic literature.

Purpose: This study was designed to investigate patterns of tooth loss in patients receiving removable partial dentures (RPDs) in eastern Wisconsin.

Material And Methods: Digital images (1502) of casts at 5 dental laboratories in eastern Wisconsin were collected.

Corrosion behavior of shape memory, superelastic, and nonsuperelastic nickel-titanium-based orthodontic wires at various temperatures.

Objective: Nickel-titanium orthodontic wires have various temperature-dependent phases. The purpose of this study was to investigate temperature-dependent corrosion characteristics of shape memory, superelastic, and nonsuperelastic orthodontic wires.

Methods: Four orthodontic wires were investigated: 27 and 40 degrees C copper Ni-Ti (superelastic and shape memory, respectively), superelastic Ni-Ti, and nonsuperelastic Nitinol Classic.
