Premium Kohno

One kit, four systems, lots of advantages

The most versatile implant on the market: the three different coronal emergences, combined with the possibility of choosing a conical or cylindrical intraosseous morphology, allow the optimum solution to be found for every surgical situation.

Premium implants have a prevalently cylindrical morphology, with a conical progression only in the apical section. Kohno implants have the same cylindrical profile as Premium implants in the most coronal portion, while they have a conical profile in the central and apical part; this tapering is greater as the implant length increases. The difference in morphology between Premium and Kohno implants can be more clearly noted in implants longer than 10 mm.

Both implants share the following features:

Thread with a pitch of 1 mm, a conical profile in the apical direction and a convex profile in the direction of the crown. These characteristics increase primary stability and avoid traumas to the bone after load application.

The design of the apical notches, the angle of the cut and the progressive reduction of the diameter of the implant core increase the fixture’s capacity to penetrate into the bone, thus guaranteeing an excellent performance in all types of bone.
Backed up by 12 years of scientific studies.

Once the intraosseous morphology has been chosen, the dentist can use 3 different coronal emergences, without having to change surgical kit or inserting technique.

STRAIGHT
The classic straight profile for narrow coronal spaces. The first section, 0.8 mm long, is smooth to ensure a portion that bacteria will find it difficult to attack and colonise.

SWITCHING PLATFORM
A 0.5 mm bevel widens gradually from the emergence/from the core, then returns to the nominal diameter of the implant at connection level. The connection platform is identical to that of the implants with a Straight profile.

TG (transgingival)
The emergence profile of the transgingival portion has been designed according to biological principles; at the same time it allows an extremely simple management of the soft tissues. The shoulder angled at 30° optimises the connection with the over-structures and distributes the prosthetic load evenly.

MOUNTLESS SURGICAL PROCEDURE
The surgical procedure contemplates inserting the implants with the Easy Insert, a driver with a patented design that prevents any deformation of the connection even at high implant insertion torques and facilitates removal of the instrument. The Easy Insert which is used on all three coronal emergences, also allows excellent intra-operative visibility.

CONNECTION WITH INTERNAL HEXAGON
All three coronal emergences are characterised by a connection with an internal hexagon 2 mm deep.
In Straight and Switching Platform implants the hexagon is stabilised by a collar on top of the platform that also contributes to a correct distribution of the forces, which in this way are unloaded along the entire implant perimeter.

Also in TG implants the internal hexagon is stabilised by an overlying internal cylindrical section, on top of which is a cone that favours the seal and helps prevent unscrewing of the prostheses. A wide 30° bevel provides a supporting shoulder for the prosthesis.

Shorty

Straight, Switching Platform and TG implants are also available in the SHORTY version, ideal for crests with reduced heights and in all cases where it is preferable not to follow a regeneration protocol. A dedicated drilling kit is provided for Shorty implants, having drills with a very short tip and a shorter total length than standard drills, very useful also in case of difficult to reach distal sectors or patients with small oral openings.

JUST ONE KIT, LOTS OF POSSIBILITIES

Just one implant-prosthetic kit for placing all versions of the Premium Kohno implant:
this solution offers many advantages, from the wider possibility of choice of the implant morphology to the availability of different prosthetic concepts.
The instruments are arranged according to a guided procedure, and the sequences of use are indicated by coloured marks that follow the same colour codes used for identifying the discs that hold the implants in the vials and for prosthetic components, making the surgical procedure absolutely simple and without any possibility of confusion for either the dentist or his assistant.
The surgical kits are supplied with the templates for the graphic representation of the implant measurements both with real dimensions and with dimensions increased by 20% and 30%, to allow choosing the most suitable implant diameters and lengths by means of radiographic or tomographic analyses. A practical and functional surgical ratchet is also included that acts as a dynamometric key for checking the tightening torque from 10 Ncm to 70 Ncm and can therefore be used both for inserting implants and for prosthesis operations.

ZirTi SURFACE

The numerous studies on surfaces carried out by Sweden & Martina have led to the development of the ZirTi surface, a substrate of the latest generation obtained with subtraction techniques by sand-blasting with zirconium oxide and acid etching with mineral acids.
Besides increasing the bone-implant contact surface, it has been demonstrated that the ZirTi surface favours cell proliferation and differentiation during processes of neo-osteogenesis and stimulates angiogenesis at a distance.
