Study Notes
Endotech II Warm Lateral Compaction Technique
- Provides 3D condensation of warm gutta-percha
Calamus System
- Drawback: risk of over- or under-condensation
- DownPack Piece: primary function is to compact and shape the gutta-percha
Endotech II Warm Lateral Compaction Technique
- Unheated spreader: used to laterally compact the gutta-percha
- Heated spreader/plugger: inserted into the canal beside the master cone, achieving 3-4 mm of the apex, using light apical pressure and semicircular motion to compact the gutta-percha
Calamus Technique
- Essential requirement: adequate heat and vibration
Systems and Techniques
- Calamus system: introduces a DownPack tip into the canal with heat and vibration modes activated
- SimpliFill technique: drawback is the risk of over- or under-filling
- Fiber Reinforced Adhesively Bonded Endodontic Resin and glass fiber post: advantage lies in its ability to resist fracture and deformation
- Cold Hydraulic condensation technique: depends mainly on the hydraulic pressure of the condensed gutta-percha
- Hot-shot system: purpose is to condense gutta-percha in the canal
- Terminal GP Lengths for Fiber Reinforced Adhesively Bonded Endodontic Resin and glass fiber post: 1.5 mm
- Cold Hydraulic condensation technique: disadvantage is that it may cause the gutta-percha to be pushed beyond the apex
- DownPack tip: works by compacting the gutta-percha when introduced into the canal
- Downback 3D device: should avoid over- or under-condensation when using this device
- Hydraulic condensation: type of technique that uses pressure to condense gutta-percha
