Substantial Equivalence Discussion

{9}------------------------------------------------

The indications for use statement of the same intended use as the primary predicate device, K220562, to support prosthetic rehabilitation when used with dental implants in the maxills or fully edentulous patients. Both the subject device and predicate device are intended for the digitally designed at validated milling centers owned by each applicant.

2. Differences

The indications for use statement of the subject device is nearly identical to the primary predicate, except for minor changes in wording that do not affect the intended use. Different validated milling centers owned by each applicant are also referenced. For PMMA Abutment are indicated to be used prior to the insertion of the final components to maintain, stabilize and shape the healing phase additionally. This is the same intended use as the reference device, K220751.

3. Discussion

The differences in the indications for use statement he subject device, primary predicate device(K220751), are only minor changes in wording and do not affect the intended use for demonstrating substantial equivalence.

Similarities

Compatibility and Implant Diameter: subject device and predicate device have the same compatible implant system.
Prosthesis Fixation: Both the subject device and the predicate device are fixed to the fixture with screws.
Sterilization Method: Both the subject device and the predicate device are provided as non-sterile and must be sterilized by the user before use.

{12}------------------------------------------------

2 Difference

Abutment Diameter, Overall abutment length and CAD/CAM design parameters: Both the predicate device have a difference in diameter before milling. However, it can be used as a reference device (K22075). It can only be machined with allowable ranges of design parameters after CAD/CAM patient-matching provided by the manufacturer.
Total length: the Dimensions of subject device are slightly different with predicate and reference devices. But the variety of the size can be possible to operate more precise treatment to meet each patient's condition.
Duration of Use: Since the subject device is a temporary prosthesis, we recommend using it for 3 months in the mouth of the actual patient.
CAD/CAM design parameters: It has different parameter for each implant system.

3. Discussion

The subject device and predicate device are used with MegaGen and Straumann and compatibility with MegaGen products has already been proven through performance tests.

The dimensions of subject device and predicate device are differnce but the length of the lentical to predicate devices. Since each system has a different connection structure, the Diameter and Overal abutment length are not same to the predicate and reference devices. This difference is to provide various diameters, lengths of prosthesis because the size and length of the alveolar bone hole more appropriate treatment for the patient. So the difference is not affecting the substantial equivalence.

However, safety of subject device was confirmed through faire the worst-ase when the user manufactures and uses it according to CAD/CAM design parameters.

Although the period of use is different from that of the suggested maximum period of use may be different as the subject device is a temporary abutment used before the final prosthesis in addition, since the expiration date of the subject device product has been verified, it does not affecting the equivalence of the predicate device.
