It is often asked if wax rims fabricated from other sources (other than Dandy) can be used to fabricate dentures; the answer is YES.
Customers who wish to use non-Dandy wax rims to establish the patient's VDO will follow the Copy Denture workflow.
The following workflow applies to patients receiving a denture using a wax rim fabricated from an outside source.
Scanning Best Practices
The outline below is a step-by-step appointment guide for our copy denture workflow. Please ensure to review our scanning guides before proceeding:
Appointment 1
** If one arch does not need a wax rim, please scan as instructed below; if a wax rim is being used on one arch or both, please proceed to Bite Registration and 360 Scan.
- On your Chairside Home screen, press “Start” and enter the patient's name.
- If they are new, please fill out the gender and birthday
- Select “Dentures” > ”Denture” > ”A New Denture”
- You will then be asked if your patient has an existing denture, to which you will answer “Yes” and press “Next”
- Then you will indicate whether the appliance is to be implant supported, answer “No” and press “Next’”
- If "Yes", and the patient already had their implants placed, please follow our Overdenture with Wax Rims Workflow.
- If "Yes", and the patient needs their implants placed, please follow our Implant Supported Overdenture Workflow.
- Indicate which arch(es) we will be creating a full denture for, press “Add to Order” and “Start Scanning”
- Take intraoral scans for the necessary arch, capturing all necessary landmarks:
- Depth of buccal and lingual vestibules
- Frena
- Hamular notches
- Retromolar pads
- Full palate including some extension into the soft palate.
Note: If facing difficulty scanning (in particular, an edentulous lower arch), doctors may take a standard impression and scan the impression's intaglio surface and borders, or scan a poured model. The patient must be fully edentulous to direct scan impressions. If the patient still has existing teeth, pour a stone model and scan the model.
Bite Registration & 360 Scan
Wax rim adjustment and information capture
- Evaluate the fit and dimensions of the wax rim in the patient's mouth and adjust accordingly.
- Prepare the wax rim for scanning
- Border mold the periphery of the wax rim using compound, wax or heavy body PVS material.
- Have the patients perform functional movements.
- Apply PVS tray adhesive, recommended.
- Apply light body wash, have patients repeat functional movements.
- Trim excess impression material that may be covering the occlusal or facial portion of the wax rim.
- Adjust the wax rim to achieve proper VDO, bite, and lip support.
- Evaluate the “F”, ”V”, and “S” sounds to verify the dimensions of the wax rim.
- Clearly mark the wax bite rim with the patient’s smile lines, canine lines, and midlines.
- Also cut notches in the occlusal and mark up the rest of the unmarked wax rim to break up the monotony of the flat wax.
- This will greatly assist in capturing the 360 scan.
- Capture bite registration and trim excess material away from the buccal and facial sides of the wax rim.
Scan
- If a single arch wax bite rim:
- Scan with wax bite rim in the mouth (from molar to midline on both left and right sides) with blue mousse (or preferred bite registration material).
- If dual arch wax bite rim(s), you have two options:
- Scan both arches in occlusion outside of mouth (full arch from molar to molar) with blue mousse (or preferred bite registration material).
- Scan inside the mouth molar to the midline on both sides.
Take photos of the patient [Highly Recommended]
- Head-on photo with the patient smiling naturally (with wax bite rim in place).
- 2 profile pictures (1 from each side) with the patient smiling naturally (with wax bite rim in place).
- [If possible] A head-on photo of the patient with cheek retractors in place (with wax bite rim in place).

- Make necessary adjustments utilizing an acrylic bur
