Semiprecision rest system for distal-extension removable partial dentures.

The history of the nonlocking type of intracoronal semiprecision rest has been traced from its origins with Neurohr in 1930, up to its present use as the Thompson dowel rest. The advantages of the use of this deep rest design and the clasp arm design for primary retention have been discussed. The Blatterfein modification of the lingual clasp arm has been introduced to overcome the problems of breakage and lack of stabilization which are present with the Thompson, Van Dam, and Wands designs.

Prefabricated metal intracoronal semiprecision attachments for removable partial dentures.

The inaccuracies of the casting and fitting processes associated with semiprecision intracoronal attachment systems may compromise the fit of the completed prosthesis. The objective of using metal prefabricated intracoronal semiprecision attachments is to improve the adaptation between the matching attachment surfaces used in the fabrication of removable partial dentures. In milled dovetail or waxed dowel rests, the attachment of one side is completed and the other is cast to match. The prefabricated attachment system presented uses a matching component cast directly against the precast metal rest-mandrel. This reduces the inaccuracies resulting from waxing, investing, and casting.

A comparison of hydrogen/oxygen and natural gas/oxygen torch soldering techniques.

The tensile strength of connectors joining bars of palladium-silver alloy and formed using hydrogen/oxygen flame soldering was compared to those formed using conventional gas/oxygen soldering. As-cast specimens served as the control. No significant differences were found between the as-cast, hydrogen/oxygen flame soldered, or the natural gas/oxygen flame soldered specimens.

Prosthodontic solutions for compromised implant placement.

The various clinical and laboratory procedures for use of auxiliary prefabricated metal screw retention, castable plastic telescopic, and custom laboratory-fabricated systems are presented as adjuncts to implant-supported restorative procedures. These devices aid in the fabrication of predictable and retrievable screw-retained, fixed-detachable implant-supported prostheses for various conditions and combinations of support. Ancillary screw systems are also useful in solving cosmetic problems when implant placement compromises this goal.

A stress-releasing intracoronal attachment for extension base removable partial dentures.

Intracoronal retainer systems incorporated into splinted abutment restorations help force distribution. The additional torque introduced by the extension-based removable partial denture is applied over multiple abutments rather than to single abutment teeth. A fixed-removable prosthesis is proposed as a solution to this situation. The Thompson dowel nonlocking semiprecision attachment system is the intracoronal retainer of choice for distal extension denture bases. It allows controlled rotation or stress relief of the removable component by minimizing detrimental transfer of traumatic forces to the abutment teeth. The design and fabrication of the manufactured version of this retainer system is described.
