Material
Fig. 1: brezirkon - structure
The „brezirkon“ material is an yttrium oxide-stabilized, tetragonal polycrystalline zirconium oxide, i.e. zirconium oxide is doped with 3 mol percent to obtain the stable rectangular structure at room temperature as well.

Source: Marcel Schweiger, Ästhetische Zahnmedizin 5, 2004





Material table
Doping with yttrium oxide results in a minimal radiation level which is far below natural radioactivity* (e.g. 1,000 Bq for 1 kg of coffee).
*Definition of Becquerel (Bq)*: The becquerel (symbol Bq) is the SI derived unit of radioactivity, defined as the activity of a quantity of radioactive material in which one nucleus decays per second. Source: Wikipedia

Material
Fig. 4: brezirkon - unsurpassed fracture toughness, i.e. integrated DefectBlocker DefektBlocker

Two values are used to measure the fracture toughness of a material:
■ K IC = critical stress intensity factor (white bar)
■ K IO = Threshold value for crack growth (grey bar)
The higher the values, the tougher the material.

Material
Fig. 5: brezirkon - excellent elasticity

The modulus of elasticity describes the elasticity of a material:
■ High value = brittle material = susceptible to fracture
■ Low value = soft material = easily deformed

Indications

■ Single tooth restoration
■ Partially edentulous ridges
Contraindications
■ N O T to be used for free-end situations
■ N O T to be used for edentulous ridges







Surgical protocol
Fig. 2: Final drill with conical design:

■ Smaller size compared to the implant body (whiteSKY design = SKY design)











Surgical protocol
Fig. 3: XL drills are cylindrical and enlarge the drill hole

■ In the crestal region (D3)
■ For hard bone (D1 + D2) not more than the implant length (whiteSKY design = SKY design)









Surgical protocol

Surgical protocol
Fig. 5: Overview - surgical procedure based on bone quality

■ D1 to XL drill → implant length less 2 mm
