Duo Over Post

Duo Over Post

Zirconia Glass Fiber Post

Duo Over Post are glass fiber posts with conical shape. As Overfibers post surfaces are particularly rough the silanization treatments are an optional.

Clinical Directions

Duo Over Post are specific For canals with accentuated ribbon section or coronally very flared. To be used in twos or threes in the same canal especially for significantly flared canals in particular in the upper incisors, in the single canal premolars and in the canine teeth.

They allow the spaces occupied by the cement to be reduced in case of significantly flared canals (e.g. retracted teeth or those with cavities round the canal).

Great advantage in the overall strength of the restored tooth.

Features & Advantages

• Highly retentive surface - Increases the post / cement adhesion without weakening it with deep grooves
• 80% glass fiber with zirconia
• high flexure strength - 1500 MPa
• Balanced flexure E-modulus - 60 GPa to better stabilize the restoration
• Translucent - to accelerate the activation of dual cements
• Radiopacity - 3.0 mm or 300% Al equivalent
• Fatigue Strength - 5 Millions Cycles Without Breaking
• Sterilization in autoclave - 135°C at 2.1 bar for 5 min without any variation of their resistance
