Intended Use

The CEREC® inLab and CEREC® Scan Dental Restoration Milling Machines are intended to be used in the computer-aided design and milling of ceramic dental restorations, including inlays, onlays, veneers, crowns (full and partial), crown caps and bridge frameworks.

Device Story

CEREC inLab and CEREC Scan are stationary dental milling units for computer-aided design and manufacturing (CAD/CAM) of ceramic restorations. Input consists of laser-scanned impressions or models of teeth. Data transfers to a PC via RS232 or wireless module. Software allows dentists or dental technicians to design restorations. Microprocessor-controlled DC and stepper motors drive grinding burrs to mill ceramic blocks based on design parameters. Used in dental clinics or labs. Output is a finished ceramic restoration. Benefits include automated, precise fabrication of complex dental structures like bridge frameworks.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Stationary table-top milling unit. Components: DC motors, stepper motors, mechanical gears, position sensors, laser scanner, grinding burrs, spindle. Connectivity: RS232 serial interface or optional wireless module to PC. Microprocessor-controlled operation. Software-driven design and milling process.

Indications for Use

Indicated for patients requiring ceramic dental restorations, including inlays, onlays, veneers, crowns, crown caps, and bridge frameworks.

Regulatory Classification

Identification

Impression material is a device composed of materials such as alginate or polysulfide intended to be placed on a preformed impression tray and used to reproduce the structure of a patient's teeth and gums. The device is intended to provide models for study and for production of restorative prosthetic devices, such as gold inlays and dentures.

Special Controls

*Classification.* Class II (Special Controls).

| Common/Usual Name: | Ceramic Dental Restoration Systems |
| Classification Name: | Impression Material |

#### 3. PREDICATE DEVICES

CEREC® 3 Ceramic Dental Restoration System with Scanning Milling Machine (K994172)

#### 4. INTENDED USE

The CEREC® inLab and CEREC® Scan Dental Restoration Milling Machines are intended to be used in the computer-aided design and milling of ceramic dental restorations, including inlays, onlays, veneers, crowns (full and partial), crown caps and bridge frameworks.

{1}------------------------------------------------

The design and milling of bridge frameworks is the only new intended use and is the subject of this 510(k) Premarket Notification.

#### ડ. DEVICE DESCRIPTION

The CEREC® inLab and CEREC® Scan are identical stationary dental milling units consisting of the same hardware, software, and operating instructions. The table-top rectangular housing encases the motors, mechanical gears, position sensors, and the milling chamber. The milling chamber contains the laser scanner, two grinding burrs and the spindle for the ceramic block. The milling process is driven by electrical DC motors and stepper motors operating under microprocessor control. The laser scanner, mounted within the milling chamber, is used to scan impressions or models of the tooth or teeth. The scanned data is then transferred to a PC computer either via an RS232 interface cable connected to the serial interface port at the rear of the milling machine or via an optional wireless module. The PC contains the software that is used by the dentist or the dental technician to design the restoration from the scanned data. The restoration is then milled from a ceramic block in the milling chamber under microprocessor control using the design parameters.

#### 6. BASIS FOR SUBSTANTIAL EQUIVALENCE

The CEREC® inLab and CEREC® Scan are substantially equivalent to CEREC® Scan that was cleared for marketing as part of the CEREC® 3 Ceramic Dental Restoration System under K994172. The main difference between the current CEREC® Scanning Milling Machines and the previous model is the additional capability of producing bridge framework restorations. However, the process for producing bridge frameworks is the same as for the other CEREC® restorations. The initial impression of the teeth at issue is made using traditional procedures and materials. The impression is fixed onto the spindle in the milling chamber, and the laser scanner is used to scan the impression. The CEREC® 3 software is then used to design the restoration based on the scanned impression. The resulting design parameters are used to mill the final restoration from the ceramic block.
