Our Acetal Resin Overpartial is available in all 16 Vitapan classical shades. Retention comes from the natural undercuts in the surface of the existing dentition, so it will not impinge the tissue.

Denmat’s Snap-On Smile is also made using an acetal resin, but the material used by their company is named Duracetal and is manufactured by Myerson. Our lab’s Acetal Resin Overpartial and the Snap-On Smile are very comparable to each other; we began fabricating ours in 2004 before DenMat began selling the Snap-on Smile.

To fabricate an Acetal Resin Overpartial case, we require a full arch impression of the maxillary and mandibular arches, bite registration, and the shade. Please take notice that each appliance will raise the vertical dimension (open the bite) for around 0.5mm. We prefer to cover the occlusal surfaces, as it adds strength to the appliances, and this is our default. If you want the occlusal surface open, which would not raise the VD, then simply inform us to do so and we will.

We design the cases according to the patient’s existing contours, while making an ideal alignment and filling edentulous spaces. If the patient desires a change in contour, please provide us information regarding the changes wanted and we can send photos of the wax up for approval prior to processing. Because Acetal Resin Overpartials are limited in the changes that can be made after processing, any change requested which was not part of the original Rx instruction and cannot be accomplished by adjustment will be billed at full charge for the remake.

The cost of our Acetal Resin Overpartial is $375 per arch, compared to DenMat’s $499.

Snap-On Smile & Snap-It!

Snap-On Smile is a non-invasive cosmetic, removable arch that snaps over existing dentition without adhesives or clasps. With the exception of pontics, the resin material stops at the gum line, so there is no coverage of any gingival tissue, and there is never coverage of the palate. The patented transitional taper design is contact lens thin in the anterior and provides increased strength in the posterior, where it’s needed. The specialized medical-grade resin is flexible, comfortable and natural-looking. Because the occlusal table of the posterior has no coverage, it will not open the bite. Chairtime is minimal; diagnose and deliver in just 2 appointments. With proper care, a Snap-On Smile or SnapIt! can last from 3 to 5 years. It’s backed by a 12-month warranty, with an optional extension to 36 months, so you can prescribe Snap-On Smile with total confidence. Specific warranty information can be found at

Snap-On Smile is available as a full arch and covers either an upper or lower arch. Also available is the Snap-it!, which is an unilateral prosthesis available for 5 units or less.  The Snap-It! is also an ideal implant temporary.  It simply snaps in place allowing the patient to eat and drink comfortably.  The Snap-it! quadrant also serves as an excellent removable partial in cases where the edentulous area(s) between the teeth are not greater than 20mm.

Turnaround time for this product is typically 14 days plus shipping time. The Snap-On Smile and Snap-it! are available in all Vita Classical shades A1 through D4.
