Intended Use

Encode® Patient Specific Dental Abutments made from oral scans provided from 3M ESPE Lava Chair Scanner and the 3M Lava COS (2.0) software are intended for use as an accessory to endosseous dental implants to support a prosthetic device in a partially or edentulous patient. Encode® Patient Specific Dental Abutments are intended for use to support single and multiple tooth prostheses, in the mandible or maxilla. The prostheses can be screw or cement retained to the abutment.

Device Story

Encode® Patient Specific Dental Abutments are custom-machined dental components designed via CAD/CAM systems. Input data consists of 3D intra-oral optical scans (using 3M ESPE Lava Chair Scanner and 3M Lava COS 2.0 software) or resin model scans. Digital files derived from these scans guide the milling process. Abutments are fabricated from titanium alloy (Ti 6Al-4V ELI) or biocompatible Zirconia TZP. Used in dental clinics, these abutments support screw- or cement-retained prostheses. The device benefits patients by providing a patient-specific fit for dental restorations. Clinicians use the output to restore function and aesthetics in edentulous or partially edentulous patients.

Clinical Evidence

Bench testing only. Validation performed on scanning equipment and software to ensure accuracy of scanning models to produce the intended design as cleared in K032263 and K052648.

Technological Characteristics

Materials: Titanium alloy (Ti 6Al-4V ELI) or biocompatible Zirconia TZP. Form factor: Patient-specific custom-milled abutment. Dimensions: Platform seating diameter 3.4-6.0mm; gingival margin diameter 3.8-16.0mm; total height 4.75-15.0mm; angulations 0-30°. Connectivity: Digital file transfer from 3M Lava COS (2.0) software to CAD/CAM milling system.

Indications for Use

Indicated for partially or edentulous patients requiring single or multiple tooth prostheses in the mandible or maxilla, supported by endosseous dental implants.

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.

Device Description:

BIOMET 3i - Encode® Patient Specific Dental Abutments K032263 & K052648

Patient Specific Dental Abutments are Encode® designed specifically for a patient using a CAD/CAM system. The abutments are designed from a threedimensional intra-oral optical scan or resin model scan and then machined/milled according to the parameters created in a digital file which are derived from the scan. The abutments are manufactured from titanium alloy (Ti 6Al-4V ELI) or biocompatible Zirconia TZP. The abutment design is limited according to BIOMET 3i Specifications, as follows:

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

| Description | Min. | Max. |

Equivalence Data:

Encode® Patient Specific Dental Abutments made from oral scans provided from 3M ESPE Lava Chair Scanner and the 3M Lava COS (2.0) software are intended for use as an accessory to endosseous dental implants to support a prosthetic device in a partially or edentulous patient. Encode® Patient Specific Dental Abutments are intended for use to support single and multiple tooth prostheses, in the mandible or maxilla. The prostheses can be screw or cement retained to the abutment.

Validation performed on scanning equipment and software to ensure accuracy of scanning models to produce the intended design as cleared in K032263 & K052648.

Encode® Patient Specific Dental Abutments made from oral scans provided from 3M ESPE Lava Chair Scanner and the 3M Lava COS (2.0) software have the same intended use and indications, principles of operation, and technological characteristics as previously cleared Encode® Patient Specific Dental BIOMET 3i Abutments. The additional option of oral scans as a source of digital images for existing design CAD/CAM software do not raise any new questions of safety or effectiveness. Validation data demonstrates that the modified process results in a finished device that is just as safe and effective as Encode® Patient Specific Dental Abutments that are currently cleared under K032263 & K052648. Thus, the Encode® Patient Specific Dental Abutments are substantially equivalent to its predicate devices.
