Ankylos

Also known as: Ankylos C/X, Dentsply Sirona Ankylos

A Dentsply Sirona implant system built around the tapered TissueCare connection, in which the abutment seats well inside a narrower platform, offered in four diameters identified by the letters A to D.

Quick facts

Current status	Current. Dentsply Sirona’s Ankylos product catalogue carries a July 2024 revision date.Manufacturer-reported[1]
Implant level	Insufficient evidence(Dentsply Sirona's Ankylos surgical manual (32671086), system brochure (32670023) and product catalogue (32671089) all describe placement depth — the implant may be placed in a crestal position or, where vertical bone volume allows, up to 1 mm subcrestally, and subcrestal placement is listed as one of the five TissueCare Concept success factors — but none of them classifies Ankylos as a bone-level or a tissue-level implant, so no classification is recorded.)
Body geometry	Screw implant supplied with a cover screw and a premounted placement head, for submerged or transgingival healing with a gingiva-forming component.Manufacturer-reported[1]
Thread design	Manufacturer documentation not located
Apex design	Manufacturer documentation not located
Material	Pure titanium grade 2, to ISO 5832-2.Manufacturer-reported[2]Taken from the "Ankylos at a glance" technical summary in Dentsply Sirona's system brochure, which lists implant material alongside implant geometry, surface, connection, diameters and lengths. The product catalogue's material index is not usable for this purpose: its ordering tables carry page references rather than material indices.
Surface	Friadent plus — a microstructured surface which Dentsply Sirona describes as having a macro-, micro- and nanostructure, with a distinct patented microstructure on the cervical region.Manufacturer-reported[3]
Connection	Ankylos TissueCare connection — a fully friction-locked and keyed tapered connection, described by Dentsply Sirona as using the taper principle for hard and soft tissue stability.Manufacturer-reported[3]
Platform switching	Dentsply Sirona describes the TissueCare concept as establishing space for tissue around the connection; the C/X variant allows indexed or non-indexed abutment positioning.Manufacturer-reported[3][1]
Available diameters	∅ 3.5 mm (A), 4.5 mm (B), 5.5 mm (C) and 7.0 mm (D).Manufacturer-reported[3][1]
Available lengths	6.6, 8, 9.5, 11, 14 and 17 mm for the ∅ 3.5, 4.5 and 5.5 mm implants; 8, 9.5, 11 and 14 mm for the ∅ 7.0 mm implant.Manufacturer-reported[3][1]

Overview

Ankylos is unusual in that the abutment does not seat on top of the implant in the ordinary sense — the TissueCare connection is a deep friction-locked taper in which the abutment sits inside a platform much narrower than the implant body, so bone and soft tissue can sit above the shoulder. That geometry is the reason Ankylos is often discussed in the context of crestal bone maintenance rather than in terms of thread design or surface. The naming convention trips people up: an implant labelled "B11" is 4.5 mm in diameter and 11 mm long, with the letter carrying the diameter and the number the length. The C/X designation refers to the prosthetic option, letting components be seated either with an index for repeatable positioning or without one for free rotation.

CONELOG PROGRESSIVE-LINE

The clearances below are held by Ankylos at brand level and cover its implant range, not Ankylos specifically. We show them here because that is the level at which regulators actually issue them.

Regulatory record

Read this before drawing conclusions. A clearance or certificate means a device may legally be sold in a market. It is not a finding that the implant performs well, and it is not a comparison against other implants. In particular, FDA "clearance" is not FDA "approval" — clearance means the FDA accepted the device as substantially equivalent to one already on the market. What these actually mean →

FDA 510(k) clearance5 records

Cleared as substantially equivalent to a predicate device. Not an FDA approval, and not a finding of safety or effectiveness.

Clearance records for Ankylos were retrieved from the issuing authority's own database, not from the manufacturer's marketing material. We attribute a clearance to a brand only when the filing holder belongs to that brand's corporate family — third-party clearances for compatible components are excluded, because they belong to the company that made the component, not to Ankylos.
