Key practical points for successful prosthetics with сomplete denture (analog method)

• Lesson program:
• – What to look for when examining a patient for the correct choice of tactics and method;
• – What influences the choice of anatomical impression material?
• – Clinically relevant parameters of a trays. Compression or decompression of the mucosa?
• – The master model is one of the parameters of success! What does a successful working model look like?
• – What are the sin of occlusal rims? Are we fixing mistakes? Or are we abandoning them?
• – Phonetic tests in prosthetic reception - need No1;
• – Recording a gothic arch? Advantages and disadvantages;
• – Does occlusion save or spoil all the work?
• – Aesthetics of prosthetics with acrylic constructions;
• – Current trends in full prosthetics.

Basic steps for making complete dentures

• Lesson program:
• – Impression with an individual trays. Detailed analysis of techniques:
• – Determination of the CR. Intraoral recording of gothic arch:
• – From manufacturing in an articulator to fixing the CR in the mouth:
• – Tasks of functional impression:
• – The choice of technique and masses in various clinical situations;
• – Ways of compression and decompression of the oral mucosa, in which clinical situations;
• – Should the edge of the functional impression be three-dimensional?
• – Thickness of the mass in the finished impression and the individual punching zone tray:
• – CR, position of central occlusion and multiple contact? Will there be an equal sign between them?
• – «Occlusal» rims are more «Aesthetic» today!
• – Gothic arch recording method as a simple and accurate mandible position determination method:
• – Rules for making in the articulator (For example CRS 10, Candulor or CentroFix, AG):
• – Recording of movements of the mandible and registration of the CR:
• – How to avoid mistakes and a large number of corrections after prosthetics?

Complete denture: digital workflow

• Lesson program:
• – Conventional vs digital impression:
• – Interarch registration:
• – Printed or milled finalization:
• – Patient outcomes.
