Intended Use

Thommen SPI® VARIOmulti Angled Abutments are intended to be used in conjunction with SPI® System dental implants in the maxillary and/or mandibular arch to provide support for splinted crowns, bridges or overdentures.

Device Story

SPI® VARIOmulti Angled Abutments are titanium dental implant abutments designed for multi-unit, screw-retained restorations. They feature an internal connection to the implant and a 30° angle. Used by dental professionals in clinical settings to support splinted crowns, bridges, or overdentures. The system includes prosthetic components like protective and temporary caps. The device provides a stable interface between the dental implant and the final prosthetic restoration, facilitating multi-unit restorative procedures.

Clinical Evidence

Bench testing only. Fatigue testing performed according to ISO 14801 (Dentistry - Implants - Dynamic fatigue test for endosseous dental implants) demonstrated sufficient resistance to fatigue and performance comparable to the predicate device.

Technological Characteristics

Material: Commercially pure titanium (ASTM F67). Design: Multi-unit, screw-retained dental implant abutment. Dimensions: 3.5 to 4.5 mm diameter, 30° angle. Connectivity: Internal connection to SPI® Dental Implant System; compatible with Nobel Biocare Multi-unit Abutment System. Sterilization: Standard methods.

Indications for Use

Indicated for patients requiring dental implant-supported restorations, specifically splinted crowns, bridges, or overdentures in the maxillary or mandibular arch.

Regulatory Classification

Identification

An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.

Special Controls

*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)

## DEVICE DESCRIPTION

SPI® VARIOmulti Angled Abutments are dental implant abutments for use with the SPI® Dental Implant System. They have an internal connection to the implant and are used for multi-unit, screw-retained, prefabricated restorations. VARIOmulti Angled Abutments are made of titanium and are available in diameters from 3.5 to 4.5 mm with an angle of 30° to the implant. The system includes dedicated prosthetic components including protective and temporary caps. SPI® VARIOmulti Angled Abutments are compatible with the Nobel Biocare Multi-unit Abutment System.

## EQUIVALENCE TO MARKETED PRODUCT

Thommen Medical AG demonstrated that for the purposes of FDA's regulation of medical devices, SP10 VARIOmulti Angled Abutment is substantially equivalent in indications and design principles to the predicate devices, SPI® VARIOmulti Angled Abutment K090153 and SPI® VARIOmulti Abutment K072856.

The subject device has the same intended use as the predicate devices and has the same Indications for Use Statement as the predicate cleared under K090153.

The subject device has the same technological characteristics as the predicate devices. The subject and predicate devices are all fabricated from the same materials (commercially pure titanium conforming to ASTM F67) and share similar design characteristics. All are multi-unit, screw retained dental implant abutments available in diameters of 3.5 to 4.5 mm. The subject and predicate devices are packaged using the same materials and are to be sterilized by the same methods.

#### PERFORMANCE TESTING

Fatigue testing was performed according to ISO 14801 Dentistry - Implants - Dynamic fatigue test for endosseous dental implants. The subject device SP1® VARIOmulti Angled Abutment was determined to have sufficient resistance to fatigue and performed comparably to the predicate device cleared under K090153.

In summary, the SPI® VARIOmulti Angled Abutment has the following similarities to the predicate devices:

- · has the same intended use,
- · uses the same operating principle.
- · incorporates the same basic design,
- · incorporates the same materials, and
- · is packaged and sterilized using the same materials and processes.
