enigmalife+

Never before in a range of denture teeth has so much attention been paid to its natural beauty. Not only do enigmalife+ look and feel like your patients’ own teeth, they help them to regain their appearance and function. Compare them to any denture teeth that you have used before, and you will see why they set the new standard. enigmalife+ are the teeth of choice when you are seeking to provide the very best dentures for your patients.  

 

Some advantages of enigmalife+ teeth are:

• Aesthetics never before achieved in a denture tooth.
• Natural opalescence and fluorescence.
• Laterals, canines and centrals are all true to nature.
• Advanced occlusal concept to improve stability and comfort.
• Can be set up to almost any occlusal arrangement.
• High strength and wear characteristics.
• Improved colour stability and plaque resistance.
• Strong bond to the denture base material.
• Eighteen beautiful shades including 16 A-D and two new bleach shades BL2 and BL3.

 

Just as important as the way in which enigmalife+ teeth restore the beauty of your patient’s appearance is the way in which they have been "designed for living". Along with appearance, the most important requirement of patients is for their dentures to help them to eat their favourite foods in comfort and without anxiety. enigmalife+ dentures will serve them for many years since they have improved durability.

enigmalife+ teeth have been specially designed to take into account the real conditions in the mouth. Since different areas of the mouth subject denture teeth to different forces one composition for all teeth is no longer a sufficient solution.

At the front of the mouth teeth come under lateral forces and can chip but rarely wear. They need to have high resistance against chemical attack and minimise plaque adhesion or discolouration. enigmalife+ anteriors are therefore made using a tough PMMA based copolymer using a double polymerisation process and incorporating PMMA pearls.

At the back of the mouth teeth will wear but rarely chip. enigmalife+ posteriors have addressed this through a tough composite formulation combining a double cross linked acrylate copolymer, UDMA resin, nano hybrid fillers and PMMA pearls. Resilience in the anteriors and incredible wear resistance in the posteriors.

 

enigmalife+ composite posterior teeth

The high quality, strength and wear characteristics of enigmalife+ composite posteriors is the result of advanced materials development and highly advanced computer controlled manufacturing at every stage of the process.

 

Component	Function
Pre-polymerised PMMA pearls	Pre-polymerised PMMA pearls included in the composite have high resistance against plaque adhesion and/or discolouration. They also reduce the polymerisation shrinkage.
Hybrid filler system 1	Very fine hybrid silanised silica particles provide the backbone for the material’s hardness and wear resistance. Refractive index matched to that of the resin matrix to provide natural translucency and refraction combined with opalescence.
Nano-hybrid filler system 2	Highly dispersed nano particle sized silica fillers. Included to increase toughness and wear resistance. By adding to the composite’s homogeneity, tooth surfaces stay smooth over the life of the denture.
Polymer matrix	Blended PMMA and UDMA resin provides a tough homogeneous matrix that resists wear, discolouration and plaque formation. Being free from porosity it has less effect on the opposing teeth and reduces bacterial invasion.
The components in combination	In combination the material formulation of enigmalife teeth form a tough, hard and homogeneous material that provides long life to the denture teeth.

Abrasion in chewing simulator

This test shows the superior abrasion resistance of enigmalife+ posteriors compared to ones made from PMMA. Method description The chewing simulator is the Model CS-4, developed by SD Mechatronik GmbH, Germany. Plate samples were prepared with 15mm diameter and 2mm thickness. As antagonists, stainless steel orbs loaded with 5ON force were used. The machine performed 640,000 cycles in water. After said 640,000 cycles, the samples were dried and their weight loss was measured. In the test series, the enigmalife composite material shows only half the abrasion of PMMA.

Vickers Hardness Tests - Best in Class

The hardness of the enamel of enigmalife+ posteriors was tested in comparison to other brands of denture teeth. Hardness can be taken as a predictor of wear.

Wear tested in University of Zurich Chewing Simulator

 

Simulated chewing was carried out to test the wear of posterior tooth material opposing the mesio buccal cusps of human molar teeth as antagonists. A bite force of 50N was employed and the materials further stressed by thermal cycling between 5o C and 50o C every 30 seconds. The material loss was measured by means of a 3DS surface roughness machine. Figures shown are relative values.

 

 

 

 

 

 

 

Bonding Test ISO 22112

In order to test the bond to denture base of the various layers of the enigmalife posteriors, teeth were manufactured from each layer in turn. A) enigmalife PMMA Neck Material B) enigmalife composite dentine material C) enigmalife composite enamel material As specified in the standard, anterior teeth, which provide a smaller bonding area than posteriors, were used. The wax was removed with boiling tap water and no further preparation of the teeth was carried out (such as sandblasting or cleaning with monomer). All teeth, including those made from enigmalife composite, bonded perfectly to the denture base (enigma high-base). There was no discernible difference between the bond to enigmalife PMMA or to enigmalife composite. This demonstrates that grinding through the enigmalife PMMA neck does not affect the strength of the bond between tooth and denture base. In a further series of tests, to confirm whether enigmalife teeth could be bonded to composite, a bonding agent (Schottlander Composite Bond) was applied according to the manufacturer’s instructions. After application of the bonding agent to them, all teeth including those made from enigmalife composite also bonded perfectly.
