Syra implants are designed to be extremely versatile, above all for full-arch rehabilitation protocols. Their conical morphology with an angle increase in the coronal section allows excellent primary stability to be obtained, a definite advantage for immediate loading. The external hexagon combines high levels of endosseous performance with the easy prosthesis fitting that has long been appreciated by multiple rehabilitation practitioners.
Even in cases of single edentulism with limited intraradicular space, Syra implants allow optimal positioning thanks to their root-shaped form with its accentuated taper.
Syra Short is a reduced length implant specifically developed to offer a solution in cases of limited vertical bone dimensions. This implant combines the characteristics of versatility of normal Syra implants with a special reduction in their lengths that promotes stabilization during the surgical phase in full-arch rehabilitation protocols despite poor bone density, allowing primary stability to be achieved in these cases as well.
The thread on Syra implants have the same constant depth along the entire body of the fixture, keeping the maximum external profile conical. This means that the morphology of the entire implant can be inserted even where bone volumes between the roots of the adjacent teeth would prevent the use of broader morphologies.
Syra SL implants have a conical core geometry paired with a constant cylindrical external profile along the entire implant length.
This characteristic means that the thread at the tip is far more accentuated. The high cutting capacity of the thread towards the tip is therefore complemented by thicker coronal thread that progressively compact the periimplant bone and guarantee great stability. The resulting morphology is indicated in post-extraction procedures and in cases of low bone compactness.
Syra Short implants also have the same connection platform with an external hexagon as Syra and Syra SL implants, and this solution is particularly indicated in cases of full-arch rehabilitations or multiple edentulism. They are available with full ZirTi treatment. An extremely shallow bevel is present around the connection platform, to guarantee prosthetic sealing. The thread pitch is constant, and is 0.75 mm. Threads have a triangular profile, and the depth of threads varies from 0.30 mm coronally to 0.70 mm at the apical tip, thereby optimizing both contact with the coagulum and implant stability.
The neck of Syra and Syra SL implants, machined for a height of 1.00 mm, broadens out beyond the conical shape of the core, giving greater coronal stability if the implant is inserted in a juxtaosseous position. The opening angle varies according to the implant diameter.
Syra Short implants are full – treated and have a platform with a diameter equivalent to the maximum thread diameter (ø 4.10 and ø 5.00 mm).
The two platforms of Syra Short implants with ø 4.10 and ø 5.00 mm are the same as those of Syra implants of normal length, allowing the same prosthetic components to be used.
Given the different angles, the neck of the implant with a diameter of 3.80 mm broadens out to a platform diameter of 4.10 mm, making it possible to use the same prosthesis on all three implant diameters. On implants with a diameter of 5.00 mm, in which the prosthetic platform also reaches 5.00 mm, either the prosthesis of the 4.10 mm platform or that of the same size can be fitted. Connections on Syra and Syra SL implants consist in a standard 2.70 mm external hexagon with a height of 0.70 mm and an M 2.0 thread. The SKIN prosthetic system, identified by a peculiar rose colour, is designed to be compatible with every implant in Syra system.
Also in Syra implants are available the CONTRACONE seal technologic, present in every implant system of Sweden & Martina.
Thanks to the tapering of both the coronal part of the implant and the abutment edge, a mechanical barrier is created that ensures a peripheral seal able to limit the bacterial infiltrate and preserves the peri-implant tissues against possible inflammations.
A range of prosthetic components with a pink anodic treatment is available for Syra , Syra SL and Syra Short implants, to ensure maximum matching even in the presence of thin biotypes. Tests carried out at the University of Padua have shown that this anodization treatment does not increase the adhesion of dental plaque, and that it has good resistance to abrasions caused by daily dental hygiene routines, while maintaining its pink coloration over time. This anodization treatment has been applied to transgingival healing screws, P.A.D. abutments and straight and angled posts and ball attachment.
Syra and Syra SL are available both in ZirTi surface, characterized by an endosseous implant body sand-blasted with zirconia oxide and etched with mineral acids and a machined neck; and also in machined version. Syra Short implants are available just in full treatment ZirTi.
