- Brief 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.
- Detailed Description
STL registration-based superimposition is an innovative technique for evaluating mandibular bone resorption in patients using removable complete dentures (RCDs). This 3D method aligns and compares digital mandible models from different time points, providing precise volumetric and surface change measurements. The process involves 3D scanning, STL file conversion, model registration, superimposition, and quantification.
Occlusal equilibration of RCDs is crucial for distributing masticatory forces evenly, influencing bone resorption patterns. Research using this technique has shown that mandibular bone resorption is non-uniform, with variations across different mandibular regions.
While offering superior accuracy and comprehensive analysis compared to traditional methods, this approach faces challenges such as potential registration errors and the need for specialized equipment and expertise. Future developments may incorporate machine learning, biomechanical modeling, and longitudinal studies to enhance understanding and clinical application in prosthodontics and oral surgery.

Group Intervention Description Occlusal equilibration using Occulosense Occlusal equilibration of complete denture using occulosense The Oculosense system, is an advanced tool in dentistry for analyzing occlusion, especially in denture equilibration. It includes an ultra-thin sensor and software that records and displays the force and timing of occlusal contacts in real-time. This system provides detailed data on force distribution, contact timing, and the center of force, offering 2D and 3D visualizations. It allows for precise, dynamic adjustments of dentures by identifying high-pressure areas and premature contacts. Despite its benefits, including high precision and quantifiable data, it is costlier and requires specialized training. Occlusal equilibration using articulating paper Occlusal equilibration of complete denture using articulating paper The articulating paper method is a widely used technique for occlusal equilibration of complete dentures. The process begins by seating the dentures properly and using thin articulating paper to mark occlusal contacts as the patient lightly bites down. High spots are identified by darker or larger marks and are carefully reduced with a fine diamond or acrylic bur. The process is repeated until even contact is achieved across all teeth. The method also involves checking occlusion during different jaw movements and making necessary adjustments. Finally, the adjusted areas are polished, and the patient's comfort is assessed.
- Primary Outcome Measures
Name Time Method 3D Quantification Assessment of Mandibular Bone Resorption Baseline, thee months, six months and twelve months 3D quantification assessment of mandibular bone resorption uses advanced imaging techniques like Cone Beam Computed Tomography (CBCT) and digital 3D software to measure and analyze bone loss in the lower jaw. This process is essential for accurate diagnosis, treatment planning (e.g., implants), and monitoring bone changes over time. It provides precise measurements, visual representations, and comprehensive analysis of bone density and volume, aiding in better clinical outcomes. Despite its advantages, it can be costly and involves radiation exposure, making it less accessible in some practices.
- Secondary Outcome Measures
Name Time Method Patient Satisfaction Baseline, thee months, six months and twelve months The Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) containing 19 questions were obtained from each of the seven conceptual domains of the OHIP (functional limitation, physical pain, psychologic discomfort, physical disability, psychologic disability, social disability, and handicap)
