Various Impression Techniques In Prosthodontics

Impression techniques in prosthodontics represent a fundamental aspect of restorative dentistry, serving as the critical foundation for successful prosthetic rehabilitation. These techniques encompass various methodologies designed to accurately capture and record the oral tissues' morphology, ensuring optimal fit and function of the final prostheses. Impressions are required for fabricating indirect restorations and indirect prostheses. The choice of impression material depends on the type of prosthesis. While some materials have multiple uses, predictable and precise impressions are achieved using specific materials for removable and fixed prosthodontics. Regrettably, substandard impressions are often accepted by clinicians in the expectation that the dental technician can 'fake and make' missing or inadequate details of intra-oral anatomy. Precise and accurate impressions are challenging and require knowledge of: Impression materials, Impression techniques and armamentarium and Soft tissue management.
