Definition of Impression Materials Impression materials in dentistry refers to substances used to create precise negative replicas of oral soft and hard tissues. These replicas, known as impressions, capture the detailed morphology of the patient’s mouth, including teeth, gums, and…
What are the key advantages of light-cured denture base materials over conventional heat-cured and self-cured acrylics? Explain the process of photopolymerization and its role in light-cured denture base materials. Discuss the properties of polymethyl methacrylate (PMMA) and its suitability for…
What is it… Acrylic dental polymers, commonly referred to as acrylic resins, represent a class of thermoplastic materials synthesized from methyl methacrylate monomer, chemically known as poly methyl methacrylate (PMMA) polymers. Intext Question: What is the difference between the formulation…
Discuss the role of dental waxes in prosthodontics. Explain the various types of dental waxes used in prosthodontics. Describe how each type of wax is used in different stages of prosthodontic treatment. Discuss the importance of accuracy and detail in…
Definition Dental waxes are thermoplastic materials composed of large, essentially paraffin-like hydrocarbons with weak intermolecular forces. These materials exhibit plasticity, becoming softened when heated and solidifying upon cooling. Beeswax can be regarded as the prototype of all waxes due to…
