Mastering Occlusion Recording: Techniques and Solutions for Prosthetic Restoration

In the realm of prosthetic dentistry, recording occlusion stands out as a cornerstone for ensuring the accuracy and success of dental restorations. Dr. Ahmad Al-Hassiny, a renowned expert in digital dentistry, recently shared his profound insights during a Medit webinar, focusing on effective strategies and troubleshooting for bite registration. This comprehensive post delves into the critical aspects of occlusion recording, presenting Dr. Ahmad’s practical advice and solutions to common challenges encountered by dental professionals.


The Essence of Occlusion in Prosthetic Dentistry

Dr. Ahmad emphasizes that recording occlusion accurately is paramount for the final outcome of prosthetic restorations. Errors in bite registration can lead to significant complications, affecting the fit and function of the prosthetic. By mastering the techniques of occlusion recording, dental professionals can minimize adjustments and ensure patient satisfaction.


Techniques for Accurate Occlusion Recording

  1. Start Posteriorly: For all bite scans, initiating the scan as posteriorly as possible ensures comprehensive data capture. This technique aids in aligning the upper and lower jaw scans effectively.
  2. Scan Movement: It’s crucial to capture both the upper and lower teeth in occlusion, along with a bit of the gingival tissue. Moving the scanner anteriorly while keeping it perpendicular to the occlusal table helps in obtaining an accurate bite scan.
  3. Data Sufficiency: Providing the software with adequate data by scanning up to the canines can facilitate a quick and accurate alignment. Over-scanning or “ironing” the area is unnecessary and can be counterproductive.


Troubleshooting Common Occlusion Recording Issues

Dr. Ahmad outlined several common issues that dental professionals face while recording occlusion, along with their solutions:

  1. Incomplete Bite Scans: Ensuring sufficient buccal data is crucial for aligning bite scans. Incomplete data often results from rushing or inadequate scan coverage.
  2. Incorrect Bite: Mostly when there’s a lot of soft tissue interference.
  3. Open Bite: A visual check to ensure patients are biting correctly before scanning can help avoid open bite issues.
  4. Intersections: Taking bite scans on both sides of the jaw can significantly reduce intersection errors. This method allows the software to optimize the occlusal data, ensuring a more accurate alignment.


Leveraging Technology: Medit Occlusion Analyzer

Introduction of the Occlusion Analyzer app exemplifies the advancements in digital dentistry tools designed to assist professionals in recording occlusion more effectively. This app provides a detailed analysis of the bite and offers manual correction options, serving as a last resort for fixing occlusion issues.


Navigating Complexities: Q&A Session Highlights

The webinar wrapped up with a Q&A session, where Dr. Ahmad answered four critical questions, providing straightforward solutions to common occlusion recording challenges:


  1. Reducing Occlusal Adjustment: The key to minimizing adjustments lies in providing accurate occlusal data to the lab. This means conducting thorough scans, carefully checking alignments, and communicating with the lab to resolve any recurring issues. Proper data ensures that the lab can create restorations that fit well without needing significant modifications.


  1. Handling Unstable Occlusal Conditions: For patients with tooth mobility, stabilizing the bite with splints or occlusal appliances before scanning can lead to more accurate recordings. This approach is particularly useful for patients with periodontal issues or those needing immediate dentures.


  1. Dealing with Bruxism: When treating patients with bruxism, the treatment objective guides the occlusion setting method. Using a leaf gauge to measure and maintain an open bite allows for precise recording, essential for planning night guards or extensive rehabilitations.


  1. Addressing Intersections and Bite Strength: Concerns about intersections in bite scans—where scans show upper teeth passing through lower teeth—are common. Minor intersections might not pose significant problems, but larger discrepancies necessitate rescanning. Using scans from both sides of the jaw can help avoid these issues, ensuring an accurate representation of the bite.



Summing Up: Key Strategies for Accurate Occlusion in Dental Restorations

Recording occlusion is a critical yet challenging aspect of prosthetic dentistry. Dr. Ahmad Al-Hassiny’s guidance helps dental professionals refine their approach to overcome challenges. Following the strategies discussed in the webinar allows for more accurate restorations, minimizing the need for adjustments and leading to better patient outcomes.
