The Easy Grip® implant system offers a simple product and a comprehensive range, consisting in threaded implants of cylindrical, anatomical and conical type constructed in titanium grade 5 ELI with diameters 3.30, 3.75, 4.50, 5.00 and 6.00 mm, and lengths varying from 5 to 15 mm which, with the different prosthetic solutions, satisfy the most common implant needs.
The implant system also includes a mini-implant for overdenture (series MBO).
The connection of the Easy Grip® implant line features a hexagon socket with rounded angles and an internal 45° bevel which increases stability and contributes to assuring correct distribution of forces by discharging the masticatory load evenly across the whole implant diameter.
These conclusions stem from the voluminous research carried out with the Polytechnic University of Marche, entitled “Study and development of fixture/abutment systems in dental implant prosthesis”, available in section “Research” of this website.
This implant connection entails a range of prosthetic solutions, all made with a single standard connection (series3), applicable to all implants in the Easy Grip® line, with integrated platform switching.
Designated prosthetic solution without integrated platform switching are available (series 4 connection) for Large, Extra Large and Extra Extra Large implants.
Since the connection has just 5 μm tolerance (friction fit) the fixture abutment coupling obtained is very steadfast, hence a suitable, easy to use abutment extracting screw (EM) or extracting key (EM2) has been designed and produced. In fact, just screw it in place of the tightening screw to obtain detachment of the prosthetic item from the implant.
For details on connection of implant systems we recommend reading the ISTISAN 07/7 report by the National Institute of Health.

The Easy Grip® connection system provides locking the fixture/abutment coupling by activating a tightening screw. With this standard method, the tightness of the tightening screw is an essential feature for proper reliability of the implant over time.
Establishing the optimal tightening value of the fixture/abutment connection has always been a critical issue for every implant line.
This value is affected by a range of variables, such as:
• the optimal torque at which to tighten the screw; in the case of the Easy Grip® line this torque has been identified in 35Ncm (see research of the Polytechnic University of Milan)
• the physical-mechanical features of the material which the screw is made of
• the manner and speed at which the screw threading is made
• the screw and connection morphology
The fixture/abutment coupling generates corrosion from titanium friction (fretting) leading to screw settling.
TFI System srl has tackled these issues with cutting edge techniques by using an anodic electrolysis treatment on contact areas in the fixture/abutment coupling which increases resistance to fretting corrosion and raising the deformation limit of its screws to 60 Ncm compared to standard production values which are around 40 Ncm, increasing by 50% the screw’s breaking resistance.
Why choose the Easy Grip® Hex connection?
Because it is simple, reliable, precise
