The Straumann Custom Abutments are indicated for single tooth replacement and multiple tooth restorations. The prosthetic restoration can be cemented.

The Straumann Custom Abutments (previously named Straumann CARES Abutments) are used for the restoration of Straumann dental implants of different types, endosteal diameters, lengths and platforms. The Custom Abutments are patient-matched abutments; the customer scans the intraoral situation and designs the shape using a Straumann-approved CAD/CAM software (such as Straumann CARES Visual). The design data is then transferred to Straumann where the fabrication of the custom abutment is carried out at a Straumann validated milling center (FEI: 3024185724 or FEI: 3011221537). The existing Custom Abutments feature a straight screw channel for the basal screw which fixes the abutment to the respective implant. The purpose of this submission is to add Custom Abutments with an angled screw channel to the Straumann Custom Abutment Portfolio. The subject Custom Abutments can be designed and manufactured with an angled screw channel (as opposed to straight), so that the screwexit is located in a favorable position (away from the incisal/occlusal edge and tooth cusps) for esthetic and functional results. The screw channel can be angled, the screwdriver maximum angle is 20°. The Custom Abutments are designed for connection to implants of the Straumann Dental Implant System. The Custom Abutments have an implant-specific connection interface for the respective compatible implant. The Custom Abutments with the SynOcta geometry (RN or WN) are designed for connection to the Straumann Tissue Level (TL) implants. Those with the CrossFit geometry (NC or RC) are designed for connection to the Bone Level (BL) and Bone Level Tapered (BLT) implants. The Custom Abutments with the TorcFit geometry, are designed for connection to the Straumann Bone Level BLX and BLC (RB/WB or WB) or Tissue Level TLX and TLC (NT, RT, WT) implants. The basal screws feature threads to secure the abutment with the implant inner geometry. The basal screws also contain the connection geometry to mate with the AS screwdrivers for installation into the implant.

Patient-specific abutment restorations, milled from Pre-milled Abutment Blanks (PMABs), are indicated for single tooth replacement and multiple tooth restorations. They are directly connected to various endosseous dental implant systems using a basal screw. Patient-specific abutment restorations milled from Pre-milled Abutment Blanks are to be digitally designed and milled using the Straumann InLab Validated Workflow. The Straumann InLab Validated Workflow is indicated for the design and fabrication of single or multiple-unit implant-borne prosthetics for the restoration of partially or fully edentulous mandibles and maxillae. The system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners or Extra-Oral Scanners. CAD software, CAM software, pre-milled abutment blanks, milling machines and associated tooling and accessories.

The Straumann InLab Validated Workflow is similar to the primary predicate K171649. It employs optical impression files that document the topographical characteristics of teeth, traditional dental impressions, or stone models. The 3Shape CAD software then allows the design of the desired restorations. The CAM software converts the digital restoration design into the tooling and tool path commands needed to fabricate the restoration. When choosing the Straumann Validated workflow, the user will only see the available and cleared components which were tested and demonstrated as part of the validated workflow. The milling command file is encrypted prior to transfer to the Roland DWX-42W Plus milling System; this encryption ensures that files generated using other CAD or CAM software cannot be used with the Straumann InLab Validated Workflow. The user will then load the milling command file into the Roland DWX-42W Plus milling System where it is decoded. The user loads the appropriate dental material blank and initiates the milling operation. This premarket notification includes restorations (one-piece metal patient-specific abutment restorations) manufactured from various Pre-milled Abutment Blanks (PMABs) from the Straumann Group companies : Institut Straumann AG and Neodent PMABs. The digital workflow using the Straumann InLab Validated Workflow includes the use of the following products: Dental Scan of the patient's situation, CAD Software, CAM Module, Milling System, Abutment Milling Blanks.

The Straumann CARES Visual/Nova Implant-borne CAD software are indicated for the design of two-piece or one-piece abutment components for single or multiple-unit implant-borne prosthetics for the restoration of partially or fully edentulous mandibles and maxillae. The system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners or Extra-Oral Scanners and CAD software. The system is used to design two-piece abutment CAD/CAM milled copings, crown and bridge restorations to be cemented onto Ti-bases, customized one-piece abutments and bridges/bars to be affixed to the endosseous dental implants using a basal screw. The use of the software requires the user to have the necessary training and domain knowledge in the practice of prosthetic design, as well as training in the use of the software.

Straumann CARES Visual/Nova is a dental CAD software to create implant-borne restorations. The software employs optical impression files that represent the topographical characteristics of the patient's intraoral situation. The Straumann CARES Visual/Nova software then allows the desired restorations. All implant-borne restorations available in Straumann CARES Visual/Nova software require FDA review and 510(k) clearance. Design specifications ("design envelope"), selectable materials, mouth positions need to be described in these 510(k) submissions. Each restorative solution is defined in a secured design library that provides the CAD software with the design specifications and restrictions for instance, minimum wall thickness, maximum angulation, cementable abutment post height etc. Standard connecting geometries e.g., abutment to implant interface are also defined in the library which cannot be edited by a user. Any dental implantborne restoration can only be created within the 510(k)-cleared design envelope. The output of the CAD software is a three-dimensional geometry file which is linked to meta data like material and patient identifier. All designed implant-borne restorations are intended to be: - sent to Straumann for manufacturing by a validated milling center, or . - milled on a validated Straumann C series or M series milling machine (only . with the CARES Visual software, K171649 and K203456) - 3D printed as a temporary crown, or temporary bridge (up to 180 days) using P pro . Crown & Bridge material on a validated Straumann P series printer (only with the CARES Visual software, K203750) Straumann CARES Visual/Nova has no patient contact since it is software.
