The Dentsply Sirona Titanium Bases system is intended for use in partially or fully edentulous mandibles and maxillae in support of single cement-retained restorations. For AT EV 3.0 S, AT TX 3.0 S, BH 3.0 S, and SB L 3.3 L titanium bases, the indication is restricted to the replacement of single lateral incisors in the maxilla and lateral and central incisors in the mandible. The system comprises three parts: - Abutment Block material (CEREC Cercon 4D Abutment Block) - Titanium Base (TiBase) - CAD/CAM system The TiBase is recommended for use with two-piece hybrid abutments and hybrid abutment crowns, used in conjunction with endosseous dental implants.

The proposed Dentsply Sirona Titanium Bases system are connected to Dentsply Sirona or third-party dental implants to facilitate the prosthetic dental restoration of edentulous areas of the oral anatomy. The proposed TiBase components are assembled (through extraoral cement bonding) with the patient specific CEREC Cercon 4D Abutment Block (K234018), to form the complete, two-piece CAD/CAM Titanium Base system abutments. The bottom half of the abutment is the TiBase component, which interfaces with the implant system-specific geometry, while the top half of the abutment is the abutment block material that is milled to form either an abutment crown or a meso-structure (the latter is subsequently finished with a crown). The TiBase component therefore serves as the "platform" on which the customized milled abutment crown or the meso-structure is bonded to, forming the complete CAD/CAM Titanium Base system abutment. The completed CAD/CAM Titanium Base system abutment is attached to the dental implant with an abutment screw. The TiBase system is part of a workflow that includes CAD/CAM software cleared in predicate device, K193408, CAD/CAM system with CEREC Chairside Software, and reference device, K200191, CAD/CAM System with inLab Software, and the abutment crown and meso-structure material cleared in reference device, K234018. The TiBase components are made of the same material as the predicate device (K193408) TiBases, which is titanium alloy Ti6Al4V, complying with ASTM F136-13. While the lower part connects to the implant system, the upper part consists of a tapered, cylindrical center post which is designed to receive the abutment crown or meso-structure to complete the finished CAD/CAM abutment. The TiBase components come in small and large sizes depending on the diameter size of the connecting implant. A notch feature on the cylindrical part of the upper portion (i.e. rotational reference and lock) ensures that there is only one position to mount either a scanbody or the abutment crown/meso-structure. The TiBase component center post includes a through-channel through which a corresponding abutment screw is inserted to allow retention of the finished abutment to the implant. The abutment screw, made of the same Titanium material, when assembled with the proposed TiBase component, is located in the internal geometry of the titanium base and does not seat in the finalized abutment crown/meso-structure. The minimum/maximum design specification limits are as follows: - Maximum angulation for the Zirconia top-half material: 20˚ - Minimum wall thickness of the Zirconia top-half material: 0.5 mm - Gingival heights of the TiBase component: 1, 2, 3 mm - TiBase component post height (i.e., length above the gingival height): ≥ 4 mm

Atlantis® Abutment in Titanium refers to the following abutments that are the subject of this 510(k): - Atlantis® Abutment, - Atlantis® Crown Abutment, - Atlantis® Conus Abutment, and - Atlantis® Healing Abutment. The Atlantis® Abutments in Titanium are patient-specific dental abutments that are intended for attachment to dental implants in the treatment of partially or totally edentulous jaws for the purpose of restoring chewing function. The design of the Atlantis® Abutments in Titanium is derived from patient dental models and is completed by Dentsply Sirona using computer-assisted design (CAD) technology according to the clinician's prescription. The final CAD design of the Atlantis® Abutment in Titanium is fabricated using computer-assisted manufacturing (CAM) to produce a customized, patient-specific device. Design and fabrication of the Atlantis® Abutment in Titanium is completed in internal Dentsply Sirona manufacturing facilities. Alternatively, the CAD design, according to the clinician's prescription, can be performed by a laboratory or clinician in an FDA cleared abutment design software (3Shape Abutment Designer Software, K151455) within the design envelope of the Atlantis® Abutments which is codified in the validated and locked design library of the cleared software. Fabrication of the Atlantis® Abutment is then completed in internal Dentsply Sirona manufacturing facilities. The Atlantis® Abutment in Titanium serves as a connection of the prosthetic construction and the endosseous implant. The lower part of the abutment is designed to fit with the specific implant geometry it is compatible, and the upper part design is according to the patient's specific anatomy. The Atlantis® Abutment in Titanium, including the Conus abutments and Healing abutments, are available in Titanium or Gold-shaded Titanium (titanium nitride layer applied using PVD (Physical Vapor Deposition)). The Crown Abutment is only available in Titanium. The Atlantis® Abutment design envelope became the basis for the other more specific designs that make up the Atlantis® Abutments in Titanium. The Atlantis® Abutment is intended for use with an endosseous implant and for single tooth restoration. The Atlantis® Crown Abutment in Titanium incorporates a design that is a combination of an abutment and an anatomically accurate crown to constitute the final finished device. It functions as a substructure that also serves as the final abutment, in a partially or completely edentulous patient. The Atlantis® Conus abutment supports a removable prosthesis (bridges and overdentures) which is retained by friction fit to the abutment. The abutment connects to the prosthesis via caps embedded in the prosthesis. The Atlantis® Healing Abutment is used with the compatible implants for temporary use during soft tissue healing after one-stage and two-stage surgeries. It is designed based on the planned final Atlantis® Abutment or Atlantis® Crown Abutment, using the same emergence profile as those abutments to achieve an aesthetic outcome during the soft tissue healing phase. Unless otherwise noted in this summary, the design envelope has remained unchanged from the previously cleared systems. Parameters such as gingival height and abutment diameter are dependent on the different implant system compatibilities.

MIS Dental Implant System is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore masticatory function. When a one-stage surgical procedure is applied, the implant may be immediately loaded when good primary stability is achieved and the occlusal load is appropriate. Narrow implants (Ø3.3mm) are indicated for use in surgical and restorative applications for placement only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws, to provide support for prosthetic devices such as artificial teeth. Mandibular central and lateral incisors must be splinted if using two or more narrow implants adjacent to one another.

The proposed MIS LYNX Conical Connection Dental Implants are intended for one- or two-stage dental implant procedures and are used in the upper or lower jaw for supporting tooth replacement to restore chewing function. The proposed dental implants have an internal conical connection with an anti-rotation index of six positions for standard and wide platforms and four positions for narrow platform. The proposed implants and cover screw are manufactured from titanium alloy (Ti-6A1-4V ELI complying with standard ASTM F136-13 - Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant). The 3.3 mm diameter size implant is available in 10, 11.5, 13, and 16 mm lengths while the 3.75, 4.2, and 5.0 mm diameter size implants are available in 8, 10, 11.5, 13, and 16 mm lengths. The proposed implants feature an outer profile which has a coronal half which is cylindrical and an apical half which is conical. The threads are designed so the implant has a self-drilling property. The geometric design also includes spiral channels (flutes) stemming from the apex. These spiral channels are designed to enable insertion torque reduction when applying reverse torque. The proposed implant design also includes circumferential grooves at the coronal area which are called "micro-rings". These horizontal micro-rings are designed to increase the BIC (Bone to Implant Contact) of the implant with the bone. The proposed implants also feature a triangular neck ("V-Cut''). The gaps around the sides of the implant neck are designed to result in an open, compression free zone. The implant-abutment connection surface of the proposed MIS LYNX Conical Connection Implant is anodized for color coding to indicate the platform: yellow for narrow platform implants, purple for standard platform implants, and green for wide platform implants. The proposed implants are packaged in either a dry or wet package. Implants packaged in the wet packaging configuration are packaged in NaCl solution and are not anodized. The liquid environment is intended to maintain the super-hydrophilic (contact angle exhibited by water in contact with the surface is equal to zero degrees) property of the proposed dental implants until the implants are installed in the patients. Cover screws are intended to be used in a two-stage surgical procedure as temporary components to the proposed endosseous implant to allow healing of the soft tissue. They are inserted into the implant and the gums are sutured over it. Their purpose is to let the osseointegration begin without any forces being applied to the implant. After a healing period, the cover screw is exposed and removed, and replaced by either a healing cap or an abutment. The cover screws are also anodized for color coding.

Indications for CEREC Cercon 4D™ CAD/CAM Blocks are: - Crowns and bridges in the posterior and anterior tooth region - Bridges with a maximum of two pontics - Inlays, onlays and veneers

CEREC Cercon 4D™ CAD/CAM Block are pre-sintered zirconia blocks composed of yttria stabilized zirconia, which are designed for CAD/CAM milling. The proposed CEREC Cercon 4D™ CAD/CAM Blocks possess a 3-dimensional contour of dentine powder to mimic the natural tooth build-up. The aim of the 3D contour technology is to achieve more aesthetic restorations than with blocks based on the current multi-layer technology. The CEREC Cercon 4D™ CAD/CAM Blocks are used for fabrication of a dental restoration. The CEREC Cercon 4D™ CAD/CAM Blocks are not provided as the finished, fully finished dental restoration. The blocks are single use, meaning that they can only be milled once and are not recommended for re-milling. The blocks are materials supplied to dental professionals that must be further processed/manufactured using CAD/CAM milling and subsequent sintering to fabricate all ceramic restorations and they are not intended to be reused as in the context of direct patient-applied devices and materials. Therefore, no reprocessing, cleaning or disinfection instructions apply because it is a dental material and not a finished dental restoration itself. After sintering of the restoration, the dental professional will finish the restoration via polishing or glazing, before insertion into the patient's mouth.

Cercon® yo ML is indicated in the anterior and posterior segments for: - Crowns - Multi-unit bridges (with a maximum of two pontics between abutment crowns) - Inlays, onlays and veneers

The proposed Cercon® yo ML is a partially sintered ceramic blank composed of yttrium oxide-(yttria-) stabilized zirconium oxide (zirconia) (Y-TZP). Cercon® yo ML is a multilayer disk built out of different shade layers and yttrium oxide contents which create a natural gradient of the restoration after sintering. The proposed device is supplied to dental professionals as a blank and then processed by machining and subsequent sintering to fabricate dental ceramic restorations.

The Endo Tabletop consists of a motorized endodontic handpiece for root canal cleaning and preparation. In addition, some models may also incorporate an electronic apex locator that assists the operator to locate the file tip in the root canal. The Endo Tabletop is intended solely for use by trained dental professionals on patients that need root canal treatment.

The Endo Tabletop is designed to drive dental endodontic instruments for a rotating treatment of root canals. Therefore, the Endo Tabletop provides different kinds of movement: 1. Continuous rotary motions (adjustable speed, torque and direction depending on the file used) 2. Reciprocating motions (speed, torque, direction, and angles depending on the file used) This functionality is provided by a Brushless Direct Current (BLDC) motor having speed and torque controls. The motor speed control is driven by a dedicated controller using pulse width modulation (PWM) of the excitation voltage and the motor torque control is performed by controlling and limiting the maximum current flow. The contra-angle transmits the motor movement in speed and direction to the endodontic file. The user can set the device by a graphical user interface on a 7" touch Thin-Film Transistor (TFT) display. The handpiece can be started/ stopped with a finger switch and foot control. All models can also be used for root canal length determination using the integrated apex locator functionality. This apex locator functionality is provided by evaluating the electical impedance between to the file clamp, placed into the dental root canal and the lip clip placed on the patient. The results of this estimation must be confirmed by standardized diagnostic imaging like an X-ray. The proposed apex locator function has two modes standalone mode. In standalone mode, the apex determination works with the lip and the endodontic file, which is connected to a file clamp. In combined mode, the apex determination works with the lip clip and the endodontic file which is connected to the contra-angle.
