IMPLANTOLOGY TABLE OF CONTENTS Implant system Material composition Bibliography on Sweden & Martina implants Sweden & Martina develops and manufactures implant systems that offer both excellent clinical functionality and perfect aesthetic results. The surfaces have been designed to obtain the best relationships between the surface roughness of the titanium and speed of bone healing. The surgical instruments are functional, easy to use and ergonomic. Training courses, continuous refresher courses and extensive assistance distinguish the service and reliability that have made Sweden & Martina...

Choosing the spire The Shelta implant is available in two versions: -- standard, with body and thread having a conical morphology -- “SL” (wide spire), having a conical body and cylindrical external profile of the spires, constant along the whole length of the implant. Shelta or Shelta SL? The conical morphology of Shelta implants makes them suitable in cases of tight interradicular spaces; the rounded apex is also ideal for sinus lift procedures. In particular, the thread of Shelta SL implants gives great primary stability in the cases of low-density bone and in post-extraction surgery....

Wide prosthetic range The common connection geometry of Shelta implants considerably simplifies prosthesis management, allowing the dental surgeon optimisation both in the purchase of prosthetic components and in the choice of the implant diameter best suited to his needs. 3 implant diameters, just 1 connection Shelta implants have a single connection geometry with internal hexagon, with an external collar that is the same for all the available implant diameters. Switching Platform All Shelta implants have a single connection hexagon, over which is a perimeter collar that is the same on all...

IMPLANT SYSTEM Shelta implants Shelta implants have a collar 0.35 mm high with the function of supporting the masticatory loads for prosthetic components; they also have a smooth neck 1.00 mm high. The thread of Shelta implants is characterised by a triangular profile, a pitch of 1.50 mm and a depth of 0.40 mm The thread of Shelta implants develops with the same geometry along the whole body of the implant. The apex of Shelta implants has two incisions that increase its penetration capacity and non-rotational property. The hemispherical apex makes Shelta implants ideal in sinus lift...

Shelta SL implants (Wide Spire) Shelta SL implants have the same prosthetic support collar and the same smooth neck as Shelta implants. The thread of Shelta SL implants maintains a constant pitch of 1.50 mm, but the depth varies along the implant body. The thread of Shelta SL implants develops keeping the maximum external profile constant. The result is a very pronounced and sharp apex. Also Shelta SL implants have a rounded apex, but the dimensions are reduced due to the more pronounced threading.

IMPLANT SYSTEM Choosing the spire Shelta and Shelta SL implants differ in the morphology of the apical part. These differences allow the ideal morphology always to be available for achieving optimum primary stability depending on the surgical practice and on the clinical conditions of the individual case. Shelta SL implants have a core with a conical geometric shape, though they maintain a constant cylindrical external diameter along the whole length of the implant. This characteristics means that the threading at the apex is much more accentuated. The resulting morphology is indicated in...

ZirTi Surface (Zirconium Sand-Blasted Acid Etched Titanium) It has been widely demonstrated that the closer the roughness is to the size of the fibroblasts, the more influence it has on cell behaviour, causing the platelet activity to increase compared to a smooth surface, thus accelerating the repair and osseointegration processes: the roughness can guide the layout of the cells, alter their metabolism and proliferation, differentiate osteoblasts and modulate production of extra-cellular matrix. For clinical findings concerning Sweden & Martina surfaces refer to the paragraph in the...

IMPLANT SYSTEM Connection Shelta and Shelta SL implants have a common prosthetic connection geometry, thus facilitating the task of the prosthodontist, irrespective of the implant platform diameter. This connection is the same as that of the ø 3.80 mm implants in the Premium Kohno (and Premium Kohno SP) family by Sweden & Martina, with which the Shelta family of implants shares the prosthetic line with the same diameter. COLLAR A collar on top of the neck gives great stability to the connection and aids the correct distribution of the masticatory forces, which are unloaded along the entire...

Switching Platform The Switching Platform is a prosthetic rehabilitation technique that aims to distance the prosthetic connection platform from the cervical bone. In fact, the abutment-implant junction is today indicated as one of the factors responsible for peri-implant bone reabsorption because it can trigger inflammatory reactions. All Shelta implants have a single connection hexagon, over which is a collar that is the same on all platforms: this considerably simplifies prosthesis management. The posts are available in two diameters, 3.30 mm and 3.80 mm. ø 3.80 mm posts can be used with...

IMPLANT SYSTEM Mountless surgical procedure The surgical procedure of insertion is extremely simple. The implant does not require a mounter for inserting into the implant site because it is engaged directly inside the connection by practical Easy Insert drivers designed to guarantee a safe grip, to prevent deformations to the corners of the connections and at the same time to allow easy removal from the implant wells. A single instrument that allows the insertion of all Shelta implant diameters. The Easy Insert drivers aid visibility of the operating field, do not occupy much space, and...

Implant packaging The implants are packaged in PMMA vials in which they are held/housed in special titanium baskets that protect the surface of the fixture against possible recontaminations due to contact. All the materials comprising the packaging have been suitably tested to verify their suitability to sterilisation, preservation and medical use. The blister packs containing the implants are packed in cardboard boxes which also contain the labels for the patient records reporting the details for traceability of the product (code and batch number). Upon opening of the vial, the implants...
