Indications for Use
Titanium Base Abutment is a titanium base placed onto Neodent dental implants to provide support for customized prosthetic restorations. It is used with a coping and crown, or crown alone, and is indicated for cement-retained single or multi-unit restorations, or screw-retained single restorations. All digitally designed copings and/or crowns for use with the Neodent Titanium Base Abutment System are intended to be sent to Straumann for manufacture at a validated milling center.
Device Story
Neodent Implant System consists of two-piece hybrid abutments (titanium base + customized superstructure). Titanium base interfaces with Neodent dental implants via Morse taper connection; provides support for prosthetic restorations. Dental laboratory uses CAD software (DWOS or 3Shape) to design patient-specific superstructures (zirconia, Co-Cr, or IPS e.max CAD). Designs sent to Straumann-validated milling center for fabrication. Clinician prescribes restoration; cements coping/crown to titanium base. System used in dental clinics; operated by dental professionals. Benefits include customized prosthetic fit and support for various restoration types.
Clinical Evidence
No clinical data submitted. Substantial equivalence supported by bench testing, including mechanical dynamic fatigue testing per ISO 14801, dimensional analysis, and sterilization validation (ISO 11135 for EO, ISO 17665 for steam). Biocompatibility supported by material identity to predicate and reference devices.

#### Device Description
This submission includes the Titanium Base abutments (two-piece hybrid abutments) and the superstructures that compose the final abutment (the second part of the two-piece abutment).
The Titanium Base abutments are provided in two prosthetic platform diameters (3.5 and 4.5 mm), each in five gingival heights (0.8, 1.5, 2.5, 3.5 and 4.5 mm). They have a Morse taper implant-to-abutment interface and an additional hexagonal indexing feature at the apical end of the Morse taper connection. The surface is as-machined, without any type of treatment
{4}------------------------------------------------
surface. The Titanium Base abutment is an intermediary prosthetic component between the implant and prosthesis; a CAD/CAM abutment design to be used as a base when fabricating a coping, crown or bridge superstructure. It is a stock abutment, previously cleared per K150367. The subject abutments are compatible with Neodent dental implants having Morse taper (CM) implant-to-interface cleared under K101945, K123022, K133592, K150182 and K150199.
The purpose of this submission is to expand the range of materials allowed in fabricating the superstructure, adding Co-Cr and IPS e.max "CAD materials to the previously cleared portfolio.
A dental laboratory equipped with an appropriate CAD system, will design a customized superstructure or restoration made of zirconia, IPS e.max CAD or Co-Cr. Each patient-specific superstructure is individually prescribed by the clinician. The minimum wall thickness of the structure is variable depending on the material, according to the table below. The maximum angling of the structure should not exceed 30°. The taper of the structure should not exceed 6°. In the case of a structure angled at the height of the cementable portion starting at the emergence profile (prosthetic height), it should not exceed 10 mm for the Morse Taper.
| Material | Minimum thickness (mm) |
|-----------|------------------------|
| CoCr | 0.3 |
| Zirconia | 0.5 |
| IPS e.max | 0.6 |
The planning of the customized superstructures must be made using the validated Dental Wings Operating System (DWOS) or 3Shape software. All digitally designed copings and/or crowns for use with the Neodent Titanium Base Abutment system are intended to be sent to Straumann for manufacture at a validated milling center.
## Indications for Use
Titanium Base Abutment is a titanium base placed onto Neodent dental implants to provide support for customized prosthetic restorations. It is used with a coping and crown, or crown alone, and is indicated for cement-retained single or multi-unit restorations, or screw-retained single restorations.
All digitally designed copings and/or crowns for use with the Neodent Titanium Base Abutment System are intended to be sent to Straumann for manufacture at a validated milling center.
## Technological Characteristics
The Titanium Base abutment is a two-piece abutment consisting of a pre-manufactured (stock) abutment made of titanium alloy conforming to ASTM F136 - Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401), and a customized superstructure made of ceramics (zirconia or IPS e.max CAD) or Co-Cr. A dental laboratory equipped with an appropriate CAD system, will design a customized superstructure or restoration, which must be milled at a Straumann validated milling center.
The following table shows a comparison among the features of subject device and its predicate and reference devices. The assessment of the differences is also included.

# Performance data
Non-clinical data submitted, referenced, or relied upon to demonstrate substantial equivalence include engineering analysis, and dimensional analysis. Testing submitted or referenced in this submission in support of a substantial equivalence determination is as follows:
- . Mechanical testing was performed on the Titanium Base abutments including the superstructures according to ISO 14801 - Dentistry - Implants - Dynamic fatigue test for endosseous dental implants and FDA document Guidance for Industry and FDA Staff - Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments dated May 12, 2004
- . Ethylene Oxide sterilization validation per ISO 11135
- . Steam sterilization validation per the ISO 17665 series standards
- . Biocompatibility is supported as the material of the titanium base is identical to the company's own predicate. In addition, the materials for construction of the superstructure are identical to Straumann reference predicates and manufactured at a Straumann validated milling center.
- . Clinical data were not submitted in this premarket notification.
# Conclusions
Based upon our assessment of the design and applicable performance data, the subject devices have been determined to be substantially equivalent to the identified predicate devices and do not raise new issues of safety and effectiveness when uses as labeled.
