Express Revision Course for Complete Dentures

Introduction

• Topic: Prosthodontics and Complete Dentures (CD)
• Importance: Diagnosis, treatment planning, rehabilitation, and maintenance of oral function, comfort, appearances, and health in patients with missing teeth and/or maxillofacial tissues using biocompatible substitutes.

Prosthodontics Overview

• Dental specialty focusing on restoring dental health for patients with missing or deficient teeth and/or maxillofacial tissues.
• Involves a comprehensive approach encompassing diagnosis, treatment planning, rehabilitation, and maintenance.

Complete Dentures (CD)

• Definition: Removable prosthesis that replaces the entire dentition and associated structures.
• Types of Steps in CD Construction:
  • Clinical Steps: Includes case history, diagnostic cast preparation, mouth preparation if required (pre-prosthetic surgery), primary impression, and more.
  • Lab Steps: Include preparation of custom tray, secondary impression, master cast preparation, occlusal rims preparation, jaw relation, teeth setting and articulation, denture processing, insertion, and post-insertion instructions/follow-up.

Classification of Patients

• Based on: Mandibular height, ridge morphology, maxillomandibular relationship, and muscle attachment.
  • Class 1: Ideal or minimally compromised with good bone height.
  • Class 2: Moderately compromised.
  • Class 3: Substantially compromised.
  • Class 4: Severely compromised with severe bone resorption.

Mental Attitude of Patients (MM House Classification)

• Introduction of the original and revised MM House classification focusing on patient attitudes towards treatment.
• Original: Philosophical, Exacting, Hysterical, Indifferent.
• Revised: Ideal, Submitter, Reluctant, Indifferent, Resistant.

Palatal Vault Shape and Retention

• U-Shaped: Most favorable for denture retention.
• Flat: Resistant to downward pull but prone to dislodgment from lateral or rotational forces. Requires balanced occlusion.
• V-Shaped: High, narrow, and least favorable for retention.

Bony Undercuts and Tori

• Maxilla: Can be relieved in the denture or need surgical removal if presenting severe undercuts.
• Mandible: Surgical correction required for undercuts and mandibular tori.

Anatomical Landmarks and Impression Steps

• Covered importance of detailed anatomical landmarks in relation to stress-bearing, supporting, and relief areas.
• Discussed specific techniques and strategies for impression taking, including considerations for different patient cases.

Steps in Complete Denture Construction

• Emphasized the sequence of clinical and lab steps required in fabricating complete dentures, including case history, primary and secondary impressions, trial fitting, and final adjustments.

Note: The lecture provides a concise but comprehensive overview of key aspects in the fabrication and fitting of complete dentures, focusing on high-yield points crucial for examinations and clinical practice.
