Indications for Use

The Link Abutment for CEREC is titanium alloy abutments placed onto HIOSSEN dental implants to provide support for customized prosthetic restorations. Link Abutment for CEREC is indicated for screw-retained single tooth or cement-retained single tooth and bridge restorations. Link abutment for CEREC All digitally designed copings and/or crowns for use with the Link abutment for CEREC is to be scanned using Sirona CEREC AC or CEREC AF or CEREC AI, designed using Sirona inLab software (Version 3.65) or Sirona CEREC Software (Version 4.2) and manufactured using a Sirona CEREC or inLab MC X or MC XL milling unit. CAD/CAM manufacturing/milling occurs at dental laboratories per the design limitations of the Sirona CEREC.

Device Story

Link Abutment for CEREC is a pre-manufactured titanium alloy (ASTM F 136) Ti-base abutment; interfaces with HIOSSEN dental implants via 11° Morse taper internal connection. Device serves as base for customized prosthetic restorations (copings/crowns) designed via Sirona CEREC/inLab CAD/CAM systems. Workflow: clinician scans implant site using Sirona CEREC AC/AF/AI; dental laboratory designs restoration using Sirona inLab (v3.65) or CEREC (v4.2) software; milling performed on Sirona MC X or MC XL units. Final assembly (abutment + ceramic mesostructure) requires autoclave sterilization (132°C, 15 min). Device provides stable prosthetic support; enables customized, digitally-designed restorations for patients with missing teeth.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing, including fatigue testing conducted under worst-case scenarios per FDA guidance, and sterilization validation per ISO 17665-1:2006.

Technological Characteristics

Material: Titanium Alloy (Ti-6Al-4V, ASTM F 136). Connection: 11° Morse taper internal connection (Mini/Regular, Hex/Non-Hex). Dimensions: 4.5mm diameter, 4.7mm post height. Sterilization: Autoclave (gravity displacement) 132°C for 15 minutes. Workflow: CAD/CAM integration with Sirona CEREC/inLab systems.

Indications for Use

Indicated for patients requiring screw-retained or cement-retained single tooth or bridge restorations supported by HIOSSEN dental implants.
