[Remounting of complete dentures].

Area of Science:

• Dental Prosthetics
• Biomaterials Science
• Clinical Dentistry

Background:

• Accurate intermaxillary relation registration is crucial for successful total denture fabrication.
• Traditional remounting methods in articulators after polymerization may compromise accuracy.
• Intraoral registration offers a direct patient-based approach.

Purpose of the Study:

• To compare the accuracy of two remounting methods for total dentures.
• To evaluate the effectiveness of intraoral grinding-in versus articulator grinding-in for determining intermaxillary relations.
• To identify the optimal method for achieving precise denture fit and function.

Main Methods:

• A remounting technique involving post-polymerization grinding within an articulator was assessed.
• An alternative method of intraoral grinding-in using central pin registration on the patient was performed.
• Mandibular and maxillary total dentures were utilized in both methods.

Main Results:

• Remounting dentures in the articulator after polymerization did not achieve the desired accuracy for intermaxillary relation.
• Intraoral registration, followed by interlocking and articulator placement, demonstrated superior accuracy.
• Patient-based intraoral grinding-in proved more effective in establishing accurate occlusal relationships.

Conclusions:

• Intraoral grinding-in is a more accurate method for determining intermaxillary relations in total denture patients.
• The central pin registration technique during intraoral grinding-in enhances prosthetic accuracy.
• Clinical evaluation on patients confirms the superiority of the intraoral registration method for precise denture remounting.
