Critical Evaluation of Impression Materials and Techniques

Impression techniques and materials used in dentistry have come a long way since the early times where it was just an attempt to record the tissues without the knowledge and appreciation of the anatomy physiology and microbiology of tissues being recorded to a more scientific well documented biologic impression making followed today. Several authors and researchers have emphasized the need to understand the concept behind the number of techniques being used today. It could well be said that prosthodontics is one of the branches of dentistry where a good impression holds the key to a successful diagnosis and treatment.
