Statement of Work-Dental-Sirona CAD CAM System

Purpose
CEREC Dental CAD/CAM System provides technological precision, superior design, and excellent performance. It acquires precise digital impressions with CEREC Primescan, designs the proposal on the Primescan using the intelligent software, then produce precise, smooth restorations with CEREC Primemill milling unit. With CEREC Speedfire, it can produce and sinter full-contour zirconia in a single visit. Fixed Dentistry involves crowns and bridges. It is a Level of Care V type of dental procedure, complex rehabilitative. Definitions
Fixed prosthodontics are individual crowns, bridges (retainers and pontics), and abutments/above the gingiva superstructure. Dental implants are placed in bone to provide an immobile structure for above gum restorations. Policy
The dental department will utilize the Dentsply Sirona CAD/CAM equipment to make many patient-specific solution for design and material processing. Digital impressions of crowns and bridges preparation will be taken with Primescan. The milling unit will enable dental professionals to manufacture restoration of excellent quality onsite and same day in the dental clinic. Procedures
The Sirona Dental CAD/CAM System is an optical impression system for computer assisted design and manufacturing (CAD/CAM) according to 21 CFR 872.3661. The system records the topographical characteristics of teeth, dental impressions, or stone models for use in the computer-assisted design and manufacturing of dental restorative The workflow is illustrated in the Sirona Software in 5 phases: Administration
Scan
Model
Design
Produce

In the Administration phase, the operator creates restoration and determines their type, Specify a production machine, and select material.

In the Scan phase, the operator performs the acquisition with inEoS X5/Blue scanner of the lower jaw, upper jaw, and buccal registration. View a 3D preview of the acquisition, add additional image catalogs, and import STL scan data.

In the Model Phase, the operator edits the model. Check or redefine the bite situation, Align the models. Check the trimmed model or manually re-trim. Check, correct or re-enter the preparation margin. Define insertion axes. Define jawline and restoration positions. Define restoration axes if necessary (abutments and telescopes only). Select the patient photo for Smile Design (if needed).

In the Design Phase, the operator select tooth form. Position and scale restorations. Individually change restoration parameters. Have initial restoration suggestions generated. Design restorations individually.
