Summary

STL registration-based superimposition is an advanced technique for assessing mandibular bone resorption in removable complete denture (RCD) patients. This 3D method involves aligning and comparing digital models of the mandible before and after RCD use, offering high accuracy and comprehensive analysis. The process includes 3D scanning, STL conversion, registration, superimposition, and quantification. Occlusal equilibration of RCDs plays a crucial role in distributing masticatory forces and influencing bone resorption patterns. Studies using this technique have revealed non-uniform resorption, with variations in different regions of the mandible. While offering numerous advantages over traditional methods, challenges include potential registration errors and the need for specialized equipment and expertise. Future developments may incorporate machine learning, biomechanical modeling, and long-term studies to enhance understanding and clinical application of this technology in prosthodontics and oral surgery.

Occlusal equilibration of complete denture using articulating paper

Occlusal equilibration of complete dentures is vital for ensuring proper function, comfort, and longevity. The process aims to evenly distribute occlusal forces, eliminate premature contacts, improve stability, reduce wear, and minimize tissue trauma. It involves methods like the articulating paper technique, pressure indicator paste, T-Scan digital analysis, and clinical observation. The process includes evaluating centric and eccentric contacts, making fine adjustments, and achieving balanced articulation. Regular follow-ups are essential to monitor occlusion and make necessary adjustments, contributing to patient satisfaction and denture lifespan.

OTHER

Occlusal equilibration of complete denture using occulosense

Occulosense denture equilibration is a digital occlusal analysis technique used to optimize denture fit and function. It employs a thin sensor placed between the dentures to measure bite force and timing. The system provides real-time data on occlusal contacts, allowing dentists to identify and adjust pressure points precisely. This process ensures even distribution of bite forces, enhancing denture stability, comfort, and longevity. T-Scan equilibration can significantly improve patient satisfaction by reducing pain, increasing chewing efficiency, and minimizing denture-related issues like sore spots and uneven wear.
