Cross-pin fixation for fixed partial dentures. 1989

L J Stumpel

A technique is described in which a standardized post system is used as a cross pin. The pin is partially embedded in the mesial or distal aspect of the abutment tooth and the remainder of the pin diameter is incorporated in the metallic substructure of the fixed partial denture. The cemented pin will add retention and resistance to the fixed partial denture. The differences between threaded and smooth cross pins are discussed.

UI	MeSH Term	Description	Entries
D002484	Cementation	The joining of objects by means of a cement (e.g., in fracture fixation, such as in hip arthroplasty for joining of the acetabular component to the femoral component). In dentistry, it is used for the process of attaching parts of a tooth or restorative material to a natural tooth or for the attaching of orthodontic bands to teeth by means of an adhesive.	Cementations
D003737	Dental Cavity Preparation	An operation in which carious material is removed from teeth and biomechanically correct forms are established in the teeth to receive and retain restorations. A constant requirement is provision for prevention of failure of the restoration through recurrence of decay or inadequate resistance to applied stresses.
