Endodontic Over Post

Endodontic Over Post

Zirconia Glass Fiber Post

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

Clinical Directions

The greater diameter can be found near the point where, on average, the post emerges from the tooth. In this way, stresses are discharged by the more resistant portion of the post, giving a great advantage in the overall strength of the restored tooth.

The clinical advantage of Endodontic Over Post

When the teeth have a moderate residual coronal structure or when more than one post is inserted in the canals of the same tooth, the coronal part of the post may interfere with either the residual dental structure or with the other post: the conicity of this portion has the effect of considerably reducing the interference in both cases, improving the insertion of the post, even in teeth with a considerable amount of residual coronal dentin.

The shapes and diameters have been calculated for use with Ni-Ti instruments, as they accurately reproduce the conicities, which are 0.04, 0.06 and 0.08.

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

Endodontic Over Post and Endodontic Drill are available in five sizes, with color coding for a corresponding use.
