Intended Use

The CSM submerged-R Implant System is especially designed for use in dental implant surgery. According to the widely accepted clinical studies successful osseointegration between fixture and the live bone depends on surgical implantation under proper conditions, shape of fixture and surface treatment technique. Implants are intended for use in support of single or multiple-unit restorations and partial or fully edentulous mandibles and maxilla. In case of Customized Hand Milling Abutment, its wall thickness is 2mm and height is 12mm. It can be reduced into Max. 7mm. The margin of the product can be modified up to Max 20°. In case of Non-Hex Cementation Abutment, it is a bridge type. Two or more products must be used. Under part of abutment is made in order to avoid restriction in connecting work.

Device Story

Endosseous dental implant system; consists of titanium fixtures and abutments. Surgically implanted into mandible or maxilla to serve as tooth root replacement; provides stable foundation for prosthetic restorations. Features internal connection (11° morse taper and hexagon type). Used by dental professionals in clinical settings. Benefits patients by restoring mastication function and supporting artificial teeth. System includes various fixture types (one-stage and two-stage) and abutment components (customized hand milling and non-hex cementation).

Clinical Evidence

Bench testing only. Fatigue testing performed per FDA guidance 'Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments' (May 12, 2004) demonstrated mechanical strength and performance equivalent to predicate devices.

### General Description

The CSM submerged - R implant system includes various one-stage Fixtures and two-stage Fixtures made of titanium. These implants are surgically inserted into the upper jaw and serve as a tooth root replacement providing a stable foundation for restorations.

This product is a fixture and an abutment prosthetic dentistry material which are dental implant infrastructures. The connection with the abutment is inserted in bones as internal connection (the morse taper 11° and Hexagon type) method. A connection will restore mastication function of the patient who has difficulties due to damage of the natural tooth and function as a supporting the prosthetic dentistry material such as artificial tooth.

### Indication for Use

The CSM submerged-R Implant System is especially designed for use in dental implant surgery. According to the widely accepted clinical studies successful osseointegration between fixture and the live bone depends on surgical implantation under proper conditions, shape of fixture and surface treatment technique. Implants are intended for use in support of single or multiple-unit restorations and partial or fully edentulous mandibles and maxilla. In case of Customized Hand Milling Abutment, its wall thickness is 2mm and height is 12mm. It can be reduced into Max. 7mm. The margin of the product can be modified up to Max 20°. In case of Non-Hex Cementation Abutment, it is a bridge type. Two or more products must be used. Under part of abutment is made in order to avoid restriction in connecting work.

### Substantial equivalence chart summary

The CSM submerged-R Implant System has a substantially equivalent intended use as the identified predicate, SQ IS System (K093321) manufactured by Neobiotech Co., Ltd. and is made of titanium metal intended to be surgically placed in the bone of the upper or lower jaw arches. The system is similar to other commercially available products based on the intended use, the technology used, the claims, the material composition employed and performance characteristics. CSM submerged-R Implant System and predicate device are made from pure titanium and the surface treatment is done with RBM.

These predicate devices and CSM submerged-R Implant System have been designed, manufactured and tested in compliance with FDA's Class II special controls guidance document root-form endosseous dental implants and endosseous dental implant abutment. The subject and predicate devices are similar in size, surface treatment, and both are sterilized via gamma irradiation. When compared with predicate devices, no new questions of safety or effectiveness have been raised for the CSM submerged-R Implant System.

### Performance Data

All of the data consistent with the recommendations in the FDA guidance document Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments, May 12, 2004, mechanical testing of the implants demonstrated that the CSM submerged-R Implant System possess mechanical strength at least equivalent to the predicate devices.

Among the information and data presented in this 510(k) submission to support the substantial equivalence of the CSM submerged-R Implant System to the specified predicate devices, fatigue testing demonstrated that there is substantial equivalence in the performance, safety and effectiveness between the CSM submerged-R Implant System and the referenced predicate devices. Fatigue testing also demonstrated that this system meets its predefined acceptance criteria and performs in accordance with its intended use.

#### Safety and Effectiveness

CSM submerged-R Implant System is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device, and it can be demonstrated that the device is as safe and effective as the predicate device, and that the new device does not raise different questions regarding safety and effectiveness as compared to the predicate device. The CSM submerged-R Implant System, as designed and manufactured, is as safe and effective as the predicate devices and therefore is determined to be substantially equivalent to the referenced predicate devices.

{3}------------------------------------------------

### Conclusion

The CSM submerged-R Implant System, subject of this submission, constitutes a safe, reliable and effective medical device, meeting all the declared requirements of its intended use. Device presents no adverse health effects or safety risks to patients when used as intended. This system has the same intended use and fundamental scientific technology as its predicate devices. Therefore, CSM submerged-R Implant System and its predicate devices are believed to be substantially equivalent.
