Comprehensive Guide to the BPS Concept for Removable Prosthetics

The Biofunctional Prosthetic System (BPS) is an advanced methodology in removable prosthetics designed to deliver optimal function, esthetics, and comfort for patients. Using state-of-the-art tools like the IvoBase system, this process ensures precision and reliability in creating dentures that meet both clinical and patient expectations. Below is a detailed breakdown based on the seven instructional video subtitles.

1. Functional Impression Stage

• Purpose: Achieve accurate anatomical and functional impressions of the upper and lower jaws.
• Technique:
  • Ensure the custom tray accommodates the lip and cheek frenulum.
  • Apply Virtual Heavy Body material for shaping margins, and use Virtual Light Body for wash impressions.
  • Engage muscles through functional movements like sucking, smiling, and tongue motions.
• Outcome: Captures essential anatomical details and ensures proper denture retention and stability.

2. Occlusal Registration and Vertical Dimension

• Steps:
  • Test phonetics using words like “Mississippi” and “sixty-six” to verify vertical dimension.
  • Adjust bite rims for proper occlusion.
  • Use the Gnathometer M for precise jaw movement tracking, ensuring the centric relation is accurately recorded.
• Key Checks: Maintain alignment with Camper’s plane and the bi-pupillary line.

3. Wax Try-In

• Objective: Validate esthetics, phonetics, and functional aspects of the denture.
• Evaluation Criteria:
  • Ensure harmonious lip support and the correct position of anterior teeth.
  • Use phonetic testing to confirm the incisal edges align with the lower lip during speech.
  • Adjust occlusal contacts for stability.
• Outcome: Provides a near-final preview of the denture’s appearance and functionality.

4. IvoBase System Overview

• Technology: The IvoBase system automates denture fabrication with a shrinkage-compensating process, using Hybrid and High Impact materials.
• Process Highlights:
  • Anatomical contouring during the wax-up saves time in finishing.
  • Stone models are prepared with precision, using silicone for protection during processing.
  • Injection and polymerization are controlled to ensure bubble-free, high-strength resin results.

5. Flasking and Material Processing

• Preparation:
  • Remove wax residue and roughen tooth surfaces for effective resin bonding.
  • Apply separating fluid for proper isolation.
• Injection:
  • Mix resin thoroughly and inject within 5 minutes to prevent material flow issues.
  • Use polymerization programs tailored for specific materials (Hybrid or High Impact).
• Result: Accurate reproduction of the wax-up design with minimized residual monomer content.

6. Denture Finalization

• Finishing:
  • Divest dentures carefully to avoid damage.
  • Polish and refine using specialized burs and sandpaper.
• Validation: Ensure that the vertical dimension remains consistent and the surface is a 1:1 replica of the wax-up.

7. Final Fitting and Patient Education

• Delivery:
  • Reassess suction, occlusion, and stability.
  • Verify contact relations during jaw movements and ensure comfort.
• Patient Guidance:
  • Educate patients on oral hygiene and the importance of regular check-ups.
  • Inform about potential pressure spots, typically resolved during the first follow-up.
• Significance: Reinforces the long-term benefits of the BPS system for both patient satisfaction and denture performance.

Advantages of the BPS Concept

• Combines scientific precision with patient-specific customization.
• Ensures superior function, esthetics, and comfort.
• Facilitates collaboration between clinicians and dental technicians for optimal results.

The BPS concept represents decades of innovation and experience, setting a gold standard in removable prosthetics. Its structured, technology-driven approach ensures that every patient receives dentures that are both functional and visually appealing.
