TECHNICAL NOTES
If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).
When it comes to devising a case for your partially edentulous patients, our planning services can ensure a successful outcome. Our service simply requires that you send us preoperative models with a bite registration and the expected esthetic outcome. We will return a complete proposal sheet that will document the exact pricing of the case, so you'll know what to charge the patient.
Case-planning designs include indications involving combination fixed & removable casework. These esthetic or conventional designs consist of case survey, crown or bridge and partial design, and estimates for your treatment-planning needs. Send us preoperative models and a bite registration, and we will design your combination case to maximize patient function, comfort and esthetics.

INDICATIONS / CONTRAINDICATIONS
Recommended for partially edentulous patients, where crowns and partials are indicated. Ideal for patients who do not want visible metal partial clasps. Interocclusal arch space of at least 5 mm is needed for most attachments.

PREPARATION
The ideal preparation for combination PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required. Feather-edge margin preparations are indicated for full-cast restorations.
Clinical preparation for rest seats, guide planes, and retention undercut. (Note: Refer to our Simplifying Combination Casework DVD for bur and disc recommendations.
