Sunflex®...Biocompatible Thermoplastic Resins,
Metal-Free, Monomer-Free Flexible Partials
Patients with metal clasp partial dentures often express that they feel self-conscious about smiling, conversing and even enjoying a meal. Not anymore with the Sunflex Partials from Sun Dental Labs. Because they are lightweight, practically invisible, and incredibly comfortable, Sunflex Partials define The Perfect Fit™.
With Sunflex you can create metal-free, lightweight flexible partial dentures that provide a natural tissue blend effect...with translucency that picks up the patient's natural tissue tone. This translucency is combined with a simulation of natural blood vessels that readily adapts to a variety of natural tissue shades. In addition to the natural coloration, each Sunflex partial is designed to follow the pattern of natural gum formations with thin clasp designs — making the restoration practically unnoticeable when worn.
With Sunflex you have a proven partial denture system that can be designed with a lightweight, metal-free base or used in combination with a cast metal partial framework for enhanced stability and natural-looking esthetics. With either option, you can be assured that you are providing your patients with the finest in partial denture treatment.
Sunflex is a pressure-injected, flexible denture base resin that is ideal for partial dentures and unilateral restorations. The resin is a blocompatible nylon thermoplastic with unique physical and esthetic properties.
The material is a specialized form of nylon in the family of Superpolymides (a very pure nylon) that will not deteriorate chemically when it comes into contact with the fluids, bacteria, and physical environment of the mouth. Available In five shade categories (Crystal, Light Pink, Pink, Medium Meharry and Dark Meharry), Sunflex is uniquely formulated to allow your patient's natural tissue tone to appear through the material for optimal esthetics.
Benefits of Sunflex:
Your patients will benefit from the natural tissue blend effect of the thin clasp design and the translucency that picks up the natural tissue tone. Virtually invisible, Sunflex Partials give your patients the confidence they need with each and every smile.
Partial dentures constructed with Sunflex can be made very thin, reducing the bulk required for strength in acrylic base materials. The thinness yields more sensation and the flexibility of the material absorbs a portion of the shock of movement under mastication. From the initial insertion, through continued wear, the patient will experience minimal obstruction, and minimal reaction to the stresses normally produced by rigid base materials.
Sunflex provides exceptional compressive, impact and bending stregth and will not deteriorate chemically when it comes into contact with the fluids, bacteria and physical environment of the mouth.
Sunflex is monomer-free and hypo-allergenic.
The flexibility of the Sunflex resin achieves the effect of a stress-breaker without attachments. The gingiva tissue is gently stimulated under mastication, and unnatural stresses on the remaining teeth are substantially reduced.
Sunflex can be used whenever you are considering a removable partial denture for your patient. There are three basic design options when considering Sunflex:
Sunflex Bilateral Partial Denture
The metal-free, flexible Sunflex Partial provides a fully-functional, yet esthetically superior, removable partial denture. Patients who have worn both conventional metal partials and Sunflex Partials report that Sunflex feels more natural in the mouth because of the thinness and lightweight design of the material. Additionally, patients report that Sunflex Partials give them more confidence when smiling and appearing in public because of excellent retention and the thin clasp designs.
Sunflex Unilateral Partial Denture
The unilateral Sunflex restoration provides you and your patients with an esthetic, functional design alternative to conventional cross-arch partial dentures. base combined with the thin clasp designs provides maximum retention, stability and esthetic appeal.
Combination Sunflex with Cast Partial
The Sunflex partial denture can also be used with cast metal frameworks for natural-appearing esthetics. The combination of the cast metal framework with the Sunflex provides enhanced stability because of the metal occlusal rests and the lingual rest seats.
The flexibility of the Sunflex resin allows the design to take full advantage of available undercuts, especially recessed areas of supporting alveolar contours. The clasps and finger extensions pass over high points and protuberances easily, relaxing into the natural undercut to provide retention without pressure at the contact point. Under mastication, the gentle movement of the base creates a slight massaging effect over the natural gum. This produces a stimulation that has been shown to retard the deterioration of natural tissue and bone.
Sunflex Partials use the Retento-Grip tissue-bearing technique for retention. No tooth or tissue preparation is needed. Simply send a master cast poured promptly and carefully from an alginate impression along with opposing model and bite registration.
Sunflex is produced to remain translucent after processing, with a simulation of natural blood vessels. The translucency readily adapts to a variety of natural tissue shades. The resin Is also available in 5 different tones ranging from lighter to darker: Crystal, Light Pink, Pink, Medium Meharry and Dark Meharry.
The best type of impression material to use is alginate. The powder should be gently stirred from the bottom of the container to the top to redistribute the heavier elements that control shrinkage in the impression. The model should be poured promptly. Most other impression materials compress the tissue too much, leading to increased adjustment time.
Immediately prior to inserting in the patient's mouth, immerse the Sunflex restoration in very hot tap water. Leave the partial in the water for about one minute. Remove the partial from the water and allow it to cool just to the point where it can be tolerated by the patient. Gently insert the partial in the mouth. The hot water treatment permits a very smooth initial insertion and a good adaptation with the natural tissues in the mouth. If the patient senses any discomfort because of tightness of a clasp, the clasp may be loosened slightly by immersing that area of the partial in hot water and bending the clasp outward. If a clasp requires tightening, the clasp area may be immersed in hot water and bent inward to tighten.
The abrasive that is most effective with a handpiece is a green silicone -carbide abrasive point usually used for porcelain or precious metals. The Green Point will permit fine adjustments to be made with a minimal degree of roughness on the surface. Simply use a rapid motion (with a light touch) and continuously vary the contact point. The point can be used for effective reduction of the periphery edge, relief in tissue-contacting areas, and relief in supporting areas to relieve tightness or difficulty in insertion and removal.
Repolishing is often not necessary when the Green Point is used properly. If repolishing is necessary, it can be done with Coarse Pumice and Brown Tripoli using a soft rag wheel. A high luster can be restored to the surface using Val-Shine polishing compound following the Tripoli application.
Add To/Reline Procedures
All tooth, clasp, or saddle additions must be completed in the laboratory using Sunflex resin. No other materials should be used when adding to Sunflex.
Relines are relatively infrequent with Sunflex because of its ability to adapt to the subtle changes in the mouth. If a reline is indicated, simply remove all adhesives from the tissue side of the partial and take a rubber base wash impression in a closed mouth position. Then take an alginate pickup impression, pour immediately and send to the laboratory.
There is no preset code for flexible partials at this time. However, if your coding system allows for an RPD, generically listed, then you may use these codes:
D5211 Maxillary partial denture-cast thermoplastic base
D5212 Mandibular partial denture-cast thermoplastic base
D5213 Maxillary partial denture-cast metal framework with thermoplastic denture bases
D5214 Mandibular partial denture-cast metal framework with thermoplastic denture bases
D5281 Removable unilateral partial denture-cast thermoplastic base
