The Prama W neck is characterized by a cylindrical part 0.80 mm high and by an hyperbolic portion 2.00 mm high, especially designed to guarantee a real continuity with the post. This absence of discontinuity gives the gum the possibility of adhere to titanium without any obstacles, and to achieve the adaptation profile established by the prosthodontist.
The Prama W implant is available in the endosseous diameters of 3.80 mm, 4.25 mm and 5.00 mm; the connection diameter is always 3.40 mm: in this way the management of the prosthetic components is easy and optimized. The hyperbolic curve of the neck has different dimensions, according to the implant diameter, allowing in this way to always have a connection diameter of 3.40 mm.
The Prama W implant is characterized by the COLLEX ONE connection, which characterizes also Premium One, Kohno One and Shelta implants. The presence of a prosthetic support collar, positioned in the inner part of the connection, guarantees a great prosthetic stability and allows the connection of the implant through the patented drivers Easy Insert, for a safe insertion in situ with mountless technique.
The Prama W implants are available in two versions:
- standard, with a cylindrical morphology documented by more than 15 years of clinical experience, facilitates the insertion in the mandibular zone; moreover it guarantees the maximum surface of bone-to-implant contact. The self-tapping apex confers great penetration ability and excellent primary stability;
- RF (“Root Form”), with a tapered morphology specifically studied for the upper jaw and for a poor mineralized bone, can obtain the maximum stability. The rounded apex of the Prama W RF implants makes them suitable also in case of sinus floor elevation.
Prama W and Prama W RF implants are available with a ZirTi endosseous body, sand-blasted with zirconium oxide and etched with mineral acids, and a UTM neck (Ultrathin Threaded Microsurface), a microthread that allows an excellent adhesion of the collagen fibers.
The Prama W surgical kit is a compact kit, designed to offer ease of use and immediacy in the sequence of instruments. The kit includes all the instruments needed to insert Prama W implants of both morphologies, both cylindrical and tapered, of all diameters and heights.
The head of the screws presents a conical support which improves the prosthetic fastening and limits loosening without obstructing the eventual removal.
CAD prostheses can be fabricated on Prama W implants with high biocompatible materials, both for temporary prostheses (as PEEK and biomedical resin) and final prostheses (as zirconium, biomedical titanium, glass fiber). It is possible to realize single or multiple prosthetic structures directly on the implant platform or on dedicated titanium supports designed by Sweden & Martina: the T-Connect.
