The Ankylos implant system is a dependable and well-designed dental implant system providing you with solutions that deliver long-term stability of hard and soft tissues, lasting esthetics and reliable functionality, which your dental patients will appreciate and Dentsply Sirona Implants as manufacturer backs with a lifetime warranty.

Key features

Over more than 25 years, the Ankylos implant system has undergone continuous improvement, driven by feedback from dental professionals, such as you. Today, the Ankylos implant system owns a number of features that differentiate it from other implant systems.

Prosthetic independence – simplified restorations

With Ankylos, every abutment fits every implant, because the TissueCare connection is identical in all implant diameters and lengths. You can therefore use any abutment with any implant. This reduces the number of prosthetic components you need, improving the esthetic result. 

Accurate placement – enhanced tissue retention

The placement system for Ankylos C/X implants enables accurate positioning of implants with a view of the implant shoulder even with subcrestal placement. Likewise, the progressive thread design makes it easy for you to insert implants into position, at the same time as it enhances tissue retention.

Locked taper – two become one

The friction-locked and keyed principle of the TissueCare connection is the result of the application of engineering principles that convert the implant and abutment into one stable rotation-locked unit with maximum mechanical stability without micro-movements.


In 2012, the Ankylos implant system celebrated its 25th anniversary. But from the beginning Ankylos was different from all the others: internal tapered connection, horizontal offset, and progressive thread design – revolutionary innovations in 1987.

TissueCare Concept

The Ankylos implant system has been scientifically and clinically proven to promote and maintain hard and soft tissue over time. Called the TissueCare Concept, this combination of unique features provides you and your patients with reliable functionality and esthetics.

One-fits-all TissueCare connection

At the root of the TissueCare Concept is the TissueCare connection. Thanks to the same dimensions in all implant diameters, your treatment protocols are simpler, and require fewer elements, using Ankylos:

The steep connection taper promotes friction lock without micro-movement, providing non-indexed prosthetics while offering an indexed option.

The Ankylos TissueCare connection ensures outstanding tissue stability thanks to the absence of any micro-movement and creates long-term healthy tissues resulting in esthetic outcomes over time. 

SoftTissue Chamber 

The TissueCare connection and the micro-rough implant shoulder allow for subcrestal placement; in combination with a horizontal offset and the concave abutment design, a chamber for soft tissue and bone is created, supporting tissue stability.

Space is created for bone formation over the implant shoulder, as well as connective tissue fibers supporting ample, healthy and natural looking soft tissues.
Gain in interdental papilla height can be observed – unique anatomical conditions promote long-term hard and soft tissue stability and long-lasting esthetic results.

Progressive thread

The progressive thread of Ankylos is designed to match bone structure and make insertion easier. It considers the following parameters:
  • The cervical geometry reduces load transfer to the cortical bone.
  • The continuously increasing thread depths transfer load to the cancellous bone.
  • Controlled loading force is achieved in the regions that are significant for the maintenance of crestal bone.
  • The thread in final position, creates primary stability allowing for immediate loading.

The Friadent plus surface

All Ankylos C/X implants are produced with the grit-blasted and high temperature-etched Friadent plus implant surface. The excellent properties of this microstructure result in early osseointegration and high bone-to-implant contact as documented in numerous in-vitro and in-vivo studies, and feature:
  • Outstanding wetting properties for activation of the primary cell apposition.
  • Unique, three-dimensional micro-design that promotes the apposition of bone-forming cells and subsequently optimum osseointegration.
  • Intensive formation of new bone with increased bone maturation in the early stage for high stability at the interface.

In combination with the advantages of the unique design features of the progressive thread, the Friadent plus surface creates high bone-to-implant contact and primary stability allowing for immediate loading.

Getting started

Incorporating Ankylos into your clinical workflow is uncomplicated thanks to a number of available modular surgical and restorative kits. 

Surgical procedures

Simple, flexible and economical surgical kits guided by a modular design, pre-assembled and equipped according to your needs.

  • Can be customized with additional modules as required
  • Instruments securely fixed in silicone holders
  • Clear and simple user guidance during surgery
  • Integrated organizer for used instruments
  • Can be easily and thoroughly cleaned

Prosthetic and laboratory procedures

The Prosthetic Set Mini includes all instruments required for the prosthetic delivery of implant restorations:

  • Prosthetic ratchet
  • Hex screw driver 1.0

Impression components according to different indications: 

  • Impression taking on implant level
  • Impression taking on abutment level

Surgical flexibility

The implant assortment for Ankylos provides you with the versatility you need to satisfy the requirements of each patient’s clinical situation. You will be supported throughout the surgical process by a simple step-by-step surgical protocol, allowing for either transgingival or submerged healing. 

Treatment planning 

You can place Ankylos using either conventional or computer-guided treatment planning. Determining the appropriate treatment planning is based on a comprehensive consultation with your patient: to determine exactly what the patient wants and expects from the treatment, discover any possible contraindications, and to explain the treatment in detail to the patient. 

Conventional treatment planning

Radiographic templates – transparent templates used to superimpose implant images upon radiographs in order to help you plan implant placement:

  • Templates are implant-specific and provide different magnifications that correspond to the radiograph magnification.
Surgical template – a thermoformed splint with radiographic balls that can be accurately repositioned in the patient‘s mouth is prepared: 
  • Can be subsequently modified to a conventionally fabricated surgical template.
  • The pre-prosthetic planning is simplified with pre-selected prosthetic components.

Learn more about conventionally surgical template in the Ankylos surgical manual (pdf).

Simplant – Computer-guided treatment planning 

Simplant dental planning software provides you with accurate and predictable surgery options. It will help you to assess your patients’ anatomy and its exact relationship to the proposed restoration. Treatment planning is easily communicated to your dental team, your dental laboratory, and the patient – everyone can see and understand what the treatment entails.

Safe three-dimensional planning in the sub-millimeter range and with reference to the desired restoration:

  • Automatic collision control, which displays too narrow clearances between implants or to the nerve.
  • Information on peri-implant bone quality for accurate conclusions on the expected primary stability.

Implant system

Ankylos C/X implants

Ankylos C/X implants are available in four diameters and six lengths. The practical size classification makes them suitable for all indications in dental implantology with a manageable number of implants. Individual implants are identified by a capital letter for diameter and a number for length (6.6–17 mm). Color-coding is used to identify the implant diameter. Site preparation instruments are also color-coded.  

Sterile packaging

Ankylos C/X implants are supplied in a double-sterile blister package with an outer carton. This type of package offers the maximum possible product safety in conformance with the increasingly rigid requirements for medical devices. The packaging also makes it easy to store all products for quick retrieval and they are easy to handle during the surgical procedure: Included with each implant is a cover screw and pre-mounted placement head.

Diameters and lengths

ANKYLOS diameters and lengths

The Ankylos thread design

You will notice the progressive implant thread is perceptibly easier to screw into position, and it also protects the tissue. This thread has been specially designed to match the structure of the bone:

  • The cervical geometry reduces load transfer to the cortical bone.
  • Continuously increasing thread depths transfer loads to the cancellous bone.
  • Maximum bone-to-implant contact in the final position.
  • Greatest possible tissue stability with crestal bone maintenance.

Surgical kits

The surgical kits for Ankylos are made from plastic and feature a modular structure including all instruments required for the standardized surgical protocol. The light plastic trays with organizers integrated into the cover for holding used instruments define a specific user sequence during surgery. All instruments are securely held in silicone holders.

Three types of surgical kits are available for Ankylos 

  1. Machine-driven protocol (A and B implants only) – includes instruments for motor-driven placement of Ankylos A- and B-implants (diameter 3.5 and 4.5 mm).

  2. Manual insertion protocol – includes instruments for placement of Ankylos A- and B or A-, B- and C-implants with manual final preparation; instruments for motor-driven final preparation are only available for A- and B-implants; similar to other drill modules, a drill module for C- and D-implants (manual) can be ordered separately and added to the kit.

  3. Guided surgery protocol – includes instruments in 8–14 mm lengths for template-guided placement of Ankylos C/X A- and B-implants; the Sleeve-on-Drill sleeves required for use with guided surgery must be ordered separately.

Ankylos instrument set

An essential precondition for a successful implant placement is your accurate and atraumatic preparation of the bone at the implant site. The instrument set for the Ankylos contains precisely designed and shaped instruments ideal for your site preparations.

Tri-Spade Drills (twist drills)

  • Implant-diameter specific
  • Multiple-use twist drills 
  • Top and bottom edges of the ring markings indicate the implant lengths
  • Areas below the 6.6 mm, and between the 8/9.5 mm and 11/14 mm markings, shaded to improve orientation

Conical Reamers

  • One reamer per implant diameter and length
  • Used for conical expansion of the depth drilling in the crestal region
  • Can also be used counterclockwise for bone condensation where bone density is low (manual reamers)


  • One tap per implant diameter can be used for all implant lengths
  • For tapping the implant site
  • It is not necessary to tap where the bone density is significantly reduced

Drilling protocol

After you have prepared the implant site, you will follow a step-by-step drilling protocol for atraumatic placement of Ankylos.

Depending on the clinical situation, you can follow either the transgingival or the submerged healing protocol. With transgingival healing of the implants, a second surgical procedure is not necessary. Simultaneously, you can take advantage of the regeneration potential of soft tissue for creating the ideal emergence profile.

1. Bone smoothing
After mobilization of the mucoperiosteal flap sharp bone crests are lightly smoothed with the internally irrigated round drill. 

2.  Pilot drilling
The direction of the implant is defined with the twist drill.

3. Depth drilling
The top edge of the ring markings indicates the implant lengths. The Tri-Spade drill A is always used first. When placing B, C or D-implants the hole is expanded in ascending order.

4. Operation of the conical reamer motorized or manual
The conical reamer is inserted into the drilled hole and preparation is started with clockwise rotation without high pressure.

5. Operation of the tap motorized or manual
The thread is prepared clockwise.

6. Removing the implant from the packaging and placing the implant driver

7. Placing the implant motorized or manual

8. Disassembly of implant driver and placement head
Hold the placement head with an open-end wrench, slacken the clamping screw of the placement head with the 1 mm hex screwdriver. Round drills and twist drills are operated at 800 rpm (revolutions per minute). For motorized operation the maximum speed is 15 rpm, the maximum torque 60 Ncm.

Keep the inner blister horizontal with the sealing foil upwards when opening and keep it after removal of the implant holder; it contains the cover screw of the implant, which is mounted after implant placement for submerged healing. The maximum speed is 15 rpm, the maximum torque 50 Ncm.


9a. Submerged healing
If the implant is planned for submerged healing, the cover screw must be placed after removal of the placement head.

9b. Transgingival healing
If transgingival healing is planned for the implant, a gingiva former of corresponding in gingival height and planned prosthetic range must be placed after removal of the placement head.

Restorative freedom

Ankylos prosthetics are available for cement-, screw-, and attachment-retained restorations in all clinical indications. In situations when you have achieved the desired primary implant stability, and there is appropriate occlusal loading, you can opt for the immediate loading of single tooth and/or multiple tooth restorations.

All prosthetic components for Ankylos are laser-marked to indicate their use:

  • Components marked with “C/” only use the cone for the connection and are not indexed – this means that the abutment components can be positioned as desired and are completely friction-locked by the cone in order to prevent rotation.

  • Components marked with “/X” are indexed – the index is used to position the abutments in the implants in one of six possible positions. In this case, it is also the cone that ensures optimum stability and rotation locking.

  • Components marked with “C/X” are used for indexed or non-indexed prosthetics.
  • Components marked with “/X” are indexed – The index is used to position the abutments in the implants in one of six possible positions. In this case, it is also the cone that ensures optimum stability and rotation locking.
  • Components marked with “C/X” are used for indexed or non-indexed prosthetics

Crown and bridge solutions

There are a number of solutions to support your crown and bridgework restorations. Prosthetics are available to assist you in simple contouring of peri-implant soft tissue, satisfying esthetically demanding single-tooth crowns and bridges in the anterior region, and improving your impression taking procedures.

Attachment-retained solutions 

The Ankylos implant system features two alternatives for attachment-retained overdentures on non-splinted implants.

Ankylos Snap Attachments C/

Ankylos Snap Attachments C/ allow you to attach an overdenture in the edentulous mandible simply and economically. You can use the existing prosthesis chairside, or have a new overdenture fabricated at your dental laboratory.

Attaching overdentures on two implants in the mandible by means of the snap attachment is a very straightforward and fast restoration option for edentulous patients. Snap Attachments are available with tapered implant connection geometry only.

Ankylos Locator abutments

Your edentulous patients want an overdenture that is secure but still easy to remove for cleaning. The self-aligning function of the Locator abutments can help you fulfill your patient requirements.  

Likewise, because Locator is a simpler attachment device, you can deliver overdentures in the maxilla and the mandible more easily, especially for patients with limited motor functions, and in cases where occlusal clearance is limited or implants diverge.

Treatment concepts

There are several restorative treatment modalities you can use with Ankylos for delivering the optimal solution to your patients.

You can choose from concepts that deliver immediate restorations to your edentulous patients; sculpture soft tissues; and provide chairside restorations through intraoral welding, for example.

The SmartFix concept

SmartFix is an implant-prosthetic procedure for the immediate restoration for edentulous patients with screw-retained bridges or bar dentures in the upper and lower jaw:

  • Avoiding critical anatomical areas – with the aid of angled implants, augmentations and critical anatomical regions can be circumvented.

  • Stable prosthetic fit – the prosthetic support base is extended distally by the angled implant position and hence optimal advantage is taken of the local bone.

  • Optimal design freedom – the extremely small abutment head provides the optimal design freedom for the superstructure in terms of height and diameter. 

  • Secure handling – abutment components are pre-mounted on a seating instrument. Delivery of the angled Ankylos Balance Base abutment is facilitated by the short and flexible seating instrument. 

  • Using CAD/CAM-fabricated superstructures – the angled Ankylos Balance Base abutments can be optimally connected to Atlantis suprastructures.
  • Freely positionable – thanks to the non-indexed Ankylos Balance Base abutments, the implant and the abutment are freely positionable. 

  • Subcrestal placement – thanks to the keyed and friction-locked TissueCare tapered connection, Ankylos can be placed subcrestally. This is useful for the SmartFix concept, because the distal implant shoulder is always positioned below the bone level when inserted at an angle. 

Ankylos TitaniumBase abutment

TitaniumBase enables your dental technician to fabricate esthetically high-quality titanium core ceramic abutments for the posterior region. At the same time, they give you all the advantages of a prefabricated, stable implant-abutment connection.

Ankylos SynCone

SynCone is an extremely economical and easy-to-use solution based on prefabricated components for providing your patients with removable bridges and dentures. SynCone is an innovative application of the telescopic technique successfully combining technical precision and economical prosthetics.

  • Rotation-locked and accurate – the friction-locked connection, without play, between the SynCone abutment and the coping as a prefabricated tapered crown offers complete mechanical stability and dependability.

  • Immediate loading – your patient will experience the success of the treatment immediately. 

  • Atraumatic – surgical procedures and the prosthetic restoration are completed during the anesthetic phase within approximately two hours.

  • Simple installation – no special implants or special instruments are required for treatment.

The WeldOne concept

WeldOne provides a stable, passively fitting framework for temporary or durable prostheses for immediate restorations – suitable for immediate or late loading. It is a fast and economical solution to deliver partial- and full-arch restorations on the same day of surgery.
This concept is exclusively designed for dental implants made by Dentsply Sirona Implants and offers the following benefits:
  • Meet patient demand for immediate restorations – surgical procedure and prosthetic delivery on the same day of surgery.

  • Significant time and cost reduction – standardized protocol with specially designed components for minimize appointments, reducing total treatment costs.

  • Less risk of fractures on temporaries – immediate reinforcement of the temporary by a titanium framework.

  • Safe and predictable for immediate loading treatment – as a consequence of reduced mobility of implants due to immediate rigid splinting a risk of implant failures during healing phases can be minimized.

  • No additional impression taking of implants necessary – simultaneous delivery of a titanium framework on implant abutments at one time; advantage of the one abutment at one time philosophy in case of abutment level restorations. 

Different fabrication procedures can be selected for this unique concept of prosthetic restoration:

  • Temporary restorations on implant level
  • Temporary or durable restorations on abutment level 

Temporary solutions

The Ankylos temporary solutions allow you the opportunity to sculpture soft tissue allowing you to harmonize the final abutment margin with soft tissue shape. Temporary abutments function as the retentive base for cement- or screw-retained crowns, or cemented-retained bridges, created by your dental laboratory.

Ankylos Balance C/ temporary abutment

Ankylos Balance C/ is used to fabricate a short-term provisional, both in the anterior and posterior regions. 
It is easily adaptable to the clinical situation with two diameters (large and small), two gingival heights (1.5 and 3.0 mm) and two angulations (0° and 15°):

  • Two-piece abutment with a separate screw.
  • Large abutment can be customized by grinding.
  • Thanks to the zirconium oxide additive it is stable and radiopaque.
  • Temporary dentures on Balance C/ abutments can be worn for a maximum of 6 months.
