Syra implants and the experience of the Syra Team 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...

Enthusiastically greeted by clinicians, a group of implantologists selected by Dr Cannizzaro of Pavia formed the Syra Team, a study group that is currently carrying out a randomized multicentre clinical trial, following a protocol devised by Dr Marco Esposito, editor of the European Journal of Oral Implantology. This study conducted on 96 patients regards the use of the Syra morphology with both regular and wide threads, and compares the clinical outcomes of the use of 3 or 4 implants for full-arch Toronto Bridge rehabilitations with immediate loading. Patients will then be followed with a long-term...

The available range Syra 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. The external hexagon connection offers a particularly indicated solution in cases of multiple edentulism with accentuated disparallelism. The three available diameters of Syra implants have the same prosthetic connection to simplify prosthesis protocols....

Syra SL 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. Threads on Syra SL implants have a constant pitch of 1.50 mm, but their depth varies along...

Surfaces Syra and Syra SL implants are available with ZirTi surface, characterized by an endosseous implant body sand-blasted with zirconium oxide and etched with mineral acids, and a machined neck. Totally machined surface is also available. ZirTi surface (Zirconium Sand-Blasted Acid Etched Titanium) The machined neck offers perfect control over the connection diameter and prevents the accumulation of plaque around the junction with the post. In addition, the particular roughness of the neck surface given by machining permits optimal adhesion of connective fibres. The ZirTi body is sand-blasted...

Machined surface Syra and Syra SL implants are also available with totally machined surface. Machined surface makes it more difficult for plaque to adhere and accumulate, and it therefore provides a less favourable environment for bacterial proliferation than surfaces with a high level of roughness. In the case of oral environments particularly predisposed to pathologies of the peri-implant tissues, machined surface can be more easily and effectively cleaned with the methods most commonly used. The particular regular morphology given by machining of the neck allows excellent adhesion of collagen...

Syra Short Syra Short implants, with heights of 4.00, 5.00 and 6.00 mm, are designed for use in clinical cases of limited vertical bone dimensions. For this reason, Short implants are characterized by a thread with a high cutting capacity, to guarantee excellent primary stability even in cases of low-density bone. Syra Short implants share the tapered geometry of Syra implants, together with the same external hexagonal connection, and are available with full ZirTi treatment. An extremely shallow bevel is present around the connection platform, to guarantee prosthetic sealing. Syra Short implants...

Mounter Syra implants are packaged preassembled with a solid titanium mounter, with an upper hexagon that ensures stable coupling with insertion drivers, extensions and the mounter stop key for the removal of the connection screw. Laser markings give excellent intraoperative visibility and allow the insertion level to be evaluated millimetre after millimetres, even when a flapless insertion protocol is being used. On one side of the mounter there is a position index corresponding to one of the faces of the hexagon of the implant-prosthesis connection, to facilitate orientation of the platform,...

Connection platform 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. Neck morphology The three nominal diameters of Syra implants (3.80, 4.25, 5.00 mm) are measured at the level of the last thread. For the morphology of Syra SL, the thread diameter remains constant, and even at the tip it therefore reaches the same maximum value as the nominal diameter. Given the different...
