Overview: Digital Wax Rims are 3D-printed tools used to determine tooth arrangement, verify jaw alignment, and evaluate aesthetics during the denture fabrication process
What is the purpose of a wax rim?
This denture tool serves three purposes: determining the position and arrangement of artificial teeth, verifying the correct jaw alignment and bite, and delivering an evaluation of the aesthetics of the denture before finalization.
Why are wax rims important?
Wax rims play a crucial role in occlusal correction within the denture fabrication process. They serve as a diagnostic and therapeutic tool, helping dentists achieve optimal bite and jaw function for the patient.
One of the most important roles of wax rims is in providing verification of jaw alignment. Confirmation of the correct vertical dimension of occlusion (VOD) and the relationship between the upper and lower jaws ensures proper biting and chewing function. The wax rim also provides a stable base for the final denture, preventing it from moving around in the mouth.
This allows patients to be involved in the denture creation process. They can provide feedback on the appearance of the denture, including the smile line, lip support, and overall facial aesthetics.
Digital Wax-Rims
Dandy’s Digital Wax-Rims are designed to improve the denture creation process. They offer significant improvements over traditional wax rims. Our wax rims are easier to scan, provide a high suction fit, and result in precise-fitting final dentures.
Benefits
Less Chair time
- Easier Scanning: Digital Wax-Rims are made from biocompatible 3D-printed nylon baseplates, which are less reflective, and texturized wax, which is easier for scanners to capture.
- Less Adjustments: Digitally designed and produced so they are closer to an adequate VDO and take less time to adjust.
High-Suction Fit
- Digital Design: The Digital Wax-Rims are digitally designed to ensure a precise, high-suction fit that is comfortable and less bulky for the patient.
- Precision: Fit down to the micron, ensuring a consistent and comfortable experience for patients.
Precise Final Dentures
- Better Impressions: The textured baseplate improves the grip for wash impressions, resulting in more accurate dentures.
Traditional Wax Rims
- Dentists are used to them
- Fabricated by traditional methods
- Not as accurate as digital methods
Non-Dandy Wax Rims
- Dentists are free to use wax rims that are either fabricated by them or by laboratories other than Dandy
- **Customers who wish to use non-Dandy wax rims to establish the patient's VDO will follow the Copy Denture workflow
Capture Intraoral Scans
Capture all necessary landmarks during the intraoral scan, including:
Depth of buccal and lingual vestibules.
Frena and hamular notches.
Retromolar pads and full palate (including soft palate extension).
Complete Bite Registration and 360 Scan
This stage involves adjusting the Wax Rim and capturing the relationship between the upper and lower jaws.
Adjust the Wax Rim
Evaluate the fit and dimensions of the Digital Wax Rim in the patient's mouth.
Adjust the Wax Rim to achieve the proper Vertical Dimension of Occlusion (VDO), bite, and lip support.
Verify dimensions by evaluating "F", "V", and "S" sounds.
Mark the Wax Rim with smile lines, canine lines, and midlines.
Perform the 360 Extraoral Scan
Border mold the periphery of the Wax Rim using PVS material.
- Have the patients perform functional movements.
- Apply PVS tray adhesive, recommended.
- Apply light body wash, and have patients repeat functional movements.
- Trim excess impression material that may be covering the occlusal or facial portion of the wax rim.
Cut notches in the occlusal surface to provide the scanner with unique landmarks.
Single Arch: Scan with the Wax Rim in the mouth from molar to midline on both sides using bite registration material.
Dual Arch: Scan both Wax Rims in occlusion outside of the mouth (full arch) or inside the mouth from molar to midline.
Frequently Asked Questions
| Do I need to return my wax-rims to Dandy? | No, this is a fully digital workflow. You do not need to return these wax-rims to Dandy. You will follow the scanning protocol. You can keep or discard of the wax-rims after your appointment. |
| How do I scan wax-rims? | Follow these instructions to continue your patient's case and scan your wax-rims. Full instructions here |
| How do I know if my scan is complete? | There are simple ways of knowing if you have a proper wax-rim scan. Follow this link learn more |
| I'm having trouble marking landmarks on the black baseplate. How should I proceed? | Any landmarks that must be engraved on the black baseplates are best done with your hand piece. |
| Will these new wax-rims change my workflow? | No, your wax-rim workflow will be the same! Due to the new materials, scanning is easier and the fit is more precise. |
| Are these wax-rims more expensive? | No, these wax-rims are the same price. |
| Why did you change the way you produce your wax-rims? |
Today, Wax-rims are produced using an analog process that results in inconsistencies. Furthermore, wax-rims are historically hard to scan due to the reflective surfaces on the wax.
Dandy’s new wax-rims have a matte black baseplate that helps aid the scanner in capturing all of the details with less effort. They also are digitally designed to have a high suction fit. This will help you save some time during this appointment. |
| What are the markings on the wax? | The markings on the wax make it easier for your scanner to capture the wax-rim. We add these during the manufacturing process. |
