Compatibility of elastomeric impression materials for use as soft tissue casts.
The communication of soft tissue contours from the clinical situation to the laboratory technician through the laboratory phases of the dental implant restoration is enhanced with the use of soft tissue casts. Modern elastomeric impression materials can function well as both the master impression and soft tissue cast materials. The purpose of this study was to test the compatibility of a variety of elastomeric impression materials and commercially available soft tissue cast materials with various matrix impression materials. Chemical interaction between the materials may result in adhesion or inhibition of the set of the soft tissue cast material. The results of this study indicated that consideration must be given to material compatibility if predictably successful results are to be achieved in soft tissue cast fabrication.

Patient's ability to localize adjustment sites on the mandibular denture.
Adjustment of new complete dentures is often required. Patients may attempt to guide such adjustments by pointing out offending areas on the dentures to the clinician. Results of this study indicate that patient-perceived locations rarely coincided with the actual area on the denture that required adjustment as determined with the use of a dye-transfer indicating method. Accurate and minimal adjustments based on clinical findings rather than patient perceptions are required to avoid losing adaptation and extension of the new dentures unnecessarily.
