Fixed Prosthodonics: Crown Preps

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

Definitely not perfect but it is my first and will have to practice practice practice!
