Why Ref-Line Teeth Are the Best Choice in the Range of Anatomic Multi-Layer Composite Teeth? 

The Main Achievements are:

• Natural look - Mamelons, Enamel, Cracks as in natural teeth
• Cervical and dentin up to the incisal edge
• Excellent Hardness - No cracking due to the use of silanized composite particles that are chemically bonded to the acrylic matrix.
• High Color Stability - of composite material
• Perfectly Reliable  - due to the advanced tooth moulds technology that enables to prevent air bubbles and natural shrinkage of material during heating and therefore all produced Ref-Line tooth shapes are perfectly repeatable.

The first advantage is in the basic development concept. Ref-line teeth were developed by an in-house technician who works in a close relationship with the company’s tool-makers. We can say that Ref-line teeth were carefully designed by a dental technician for dental technicians. The tooth shapes, surface texture, internal layering system and shading, mamelons, micro cracks and smaller imperfections were all taken under consideration with no compromise to make the tooth line as close as possible to natural teeth. It is a perfect combination of natural shapes with high-end digital production technologies, new production processes and the newest material development enclosed in one product.

Completely new high anatomical shapes were taken directly from natural teeth. Physical and digital modelling was done by a dental technician with the best compromise between the natural tooth shape and production mould. Even the finest details were enhanced. New layering and shading system with intensive cervical and dentin colour and whitish translucent enamel allows high customization and different colour effects by only grinding the enamel layer. The high colour intensity assures colour stability even with the exportation of bigger amounts and has mask functionality over metal substructures. Darker canines, darker cervical areas, mamelons, mesial and distal transparency makes dentures look just real.

• Warm intensive cervical, light enamel colour and diverse surface structure make the teeth look natural.
• Mesial and distal transparency, mamelons and cracks copy the natural structure of teeth, which remains preserved even after sanding.
• Anatomic posterior teeth shape, with a high level of detail on the occlusal surface.
• Ref-line teeth are made from a new composite acrylic material. The material is composed of pre-cross-linked polymer and the matrix reinforced by inorganic micro-fillers.
• Compared to conventional acrylic, the new Ref-line material offers improved resistance to the mechanical wear good resistance to plaque adhesion, colour stability, higher hardness, excellent polishing properties and good adhesion to denture base materials.

The bottom of the tooth follows the shape of the gum, therefore very little to no grinding at all is necessary to set up a tooth. And even in really tight conditions with little height, there is a cervical opening at the bottom of posterior teeth that reduces/limits the grinding to the outer border therefore with big-time savings. The bottom opening was designed to facilitate the modelling of retentions in implant-supported dentures and facilitates the creation of teeth retentions with thermo-injected non-PMMA denture base materials. Anterior teeth are subdivided into different categories by the application. Wide necks of some anterior teeth allow full coverage of metal substructures in combined work and/or on implant-supported dentures.

• The design of the retention hole allows faster modelling of retention pins on the implant bars.
• Less material removal means a faster teeth setup due to a retention opening at the bottom of posterior teeth.
• Only two lateral holes are needed to provide mechanical retention for pressable base materials.
• The tooth bottom follows the ridge shape. There is even a retention grid space for partial dentures on posterior teeth.

Extremely aesthetically and perfected tooth design was supplemented with advanced material. In the development of the material, we followed guidelines of chemical findings and avoided the mistakes made by different producers evident from the market. New composite acrylic material is composed of pre-cross-linked polymer and the matrix reinforced by inorganic nano- and micro-fillers. Compared to conventional acrylic, the new Ref-line material offers improved resistance to the mechanical wear (50% improvement), higher hardness (15% improvement) by unchanged elasticity, good resistance to plaque adhesion, colour stability, excellent polishing properties and still perfect adhesion to denture base materials due to controlled use of silanized composite particles. Together with newly designed moulds for material injection and improved production process, we ensure the production of exact, compact and perfectly shaped teeth. Due to our continuous injection production technology density of the material is much higher in comparison with conventional techniques and tooth layers are not only chemically but also physically pressed into each other. No bubbles, no shrinkage, no excess material ensures constant repeatability which is crucial in digital dentures design.
