Now that Operative Dentistry is over, It's time to start Fixed Prosthodontics. We started with crown preps and here is my first Proximal & Height of Contour Reduction
Buccal & Lingual Reduction - 0.8-1.5mm
- In the first plane I made the axial walls parallel
then tapered in the second plane - approx. 3-6 degrees-Ensured maxillary lingual cusps were tapered towards the central fossae of the opposing mandibular tooth- Kept original form, outline and orientation of the tooth Occlusal reduction- 1.5 - 2mm- Reduced occlusal surface following the outline of the cusps and keeping the central groove
