Sold out
Rs. 6,050.00

Z250 XT Nano Hybrid universal dental restorative kit is specifically designed to offer easy to polish and providing good aesthetic result. It permanently bonds the composite to the tooth structure. It is available in 12 shades, two of which are Opaque. All shades are radiopaque and fluorescent. Z250 XT is made available as syringes and capsules.

What is a nanohybrid?
The nanohybrid resins generally presented inferior properties compared with the nanofilled composite and either similar or slightly better properties compared to the microhybrid material. Under clinical conditions, nanohybrid resins may not perform similarly to nanofilled materials.

Features:

  • High strength
  • Good wear resistance
  • Improved polish retention
  • Easy to polish
  • Direct anterior and posterior restorations including occlusal surfaces
  • Core build-ups
  • Splinting
  • Indirect restorations including inlays, onlays and veneers

Difference between different types of composite fillers

Microfills Microhybrid Nanohybrid
Particle size 0.01 to 0.1 µm (agglomerated) 1-      0.1- to 2-µm glass 1- 0.1- to 2-µm glass or resin micro particles
  2-      40-nm silica 2- ≤100-nm nanoparticles
Clinical use · Sub gingival lesions w.r.t (1) Moderate-stress areas requiring optimal polishability (Classes III, IV) Wrt  (1) Moderate-stress areas requiring optimal Polishability
· Smooth surfaces   w.r.t (2) (Classes III, IV)
· Anterior aesthetic    
Advantages · Simulates actual enamel surface · Simulate the dentin of natural tooth structure. · exhibit higher polishability
· Highest aesthetic level · Higher strength can be used as substructure under microfills enamel layer. · better surface smoothness
· Better wear properties than any other ·  Most Opaque of the 3 composite types, also great for masking out unwanted color and achieving extreme color changes. ·  lifelike opacious translucency
· High luster and hold their polish over time    
· Stain and plaque resistant    
· Highest reflective and refractive indices hence more realistic translucency    
Disadvantages · Less strength than micro and nanohybrid · Less polishable · donot hold their polish long  as microfills but better than microhybrids
· Dec. water sorption · More difficult to marginate, and will wear faster than microfill resins. · More susceptible to plaque and staining over time.
    · Less biological compatible with gingival tissues
Indications · Class III & calss V · Anterior and posterior restorations · posterior restorations
  · Can be used to fill the bulk of the tooth · veneering manidbular anteriors
    ·  building up incisal edges
    ·  class IV restoration
    ·  increasing cuspid rise
    · when the doctor wants to use only one material

 

How to Use ?

Step 1- Proper preparation technique for each procedure.

Step 2- Method of material placement—this involves complete understanding of tooth morphology and the sculpting techniques necessary to achieve it.

Step 3- Knowledge of layering and how to use various materials in combination—this will enhance the overall physical, aesthetic, and biologic results of each procedure (ie, when to use microhybrid, nano-fill, microfill, tints, and opaquers).

Step 4- Utilizing the proper finishing and polishing techniques—this will achieve the most lustrous, plaque- resistant, stain-resistant, and wear-resistant finished result.

Step 5- One must understand when and how to use finishing burs, discs, rubber impregnated points, and polishing paste to obtain the desired result.
