From natural teeth to implantology The Prama system has been developed in collaboration with Dr. Ignazio Loi, transferring the concepts of the B.O.P.T. technique (Biologically Oriented Preparation Technique) from the prosthesis on natural teeth to the prosthesis on implants. The Prama system offers all the characteristics needed for an implant-prosthesis rehabilitation for the benefit both of hard and soft tissues, which respects their biology and which helps their re-growth and aesthetics. The Prama implants are available in two versions: • Standard, with a cylindrical morphology,...

“All the procedures which characterize the B.O.P.T. technique on dental elements have been transferred also to the implantology, achieving the creation of Prama, the fixture originated by the principles of the B.O.P.T. technique in order to simplify the implant prosthodontics. The freedom of choice between tapered or cylindrical morphology and two different surface treatments make the surgical positioning simple and safe. The emergence profile with hyperbolic geometry allows an effective continuity between the implant and the post; the anodic treatment allows a perfect mimetism with the...

Prama The cylindrical morphology of the Prama implants, with 15 years of clinical experience, allows to take advantage of the implant design according to the site and the most appropriate use. In particular, the cylindrical body facilitates the insertion in the mandibular bone, which is often poorly vascularised and highly corticalised. Moreover it guarantees the maximum surface of bone-to-implant contact, for the benefit of the BIC percentage which can be obtained. The transgingival neck of the Prama implants is characterized by a straight cylindrical section 0.80 mm high, followed by a...

Prama RF (Root Form) Prama RF is the tapered version of the Prama implant, with which it shares the connection and the transgingival neck. Due to its pure tapered morphology Prama RF is particularly recommended for the insertion in the upper jaw; in the maxillary bone or in a poorly mineralized bone, in fact, the RF implant reaches the maximum stability, thanks to its morphology. The machined surface of the transgingival neck together with the golden colour obtained with a controlled passivation process, facilitates the aesthetics and the re-growth of the soft tissues around it. The body...

Surfaces The Prama and Prama RF implants are available with the ZirTi Gold Machined surface, characterized by a machined transgingival neck, submitted to a particular controlled passivation process which gives to it a golden yellow colour, and by the endosseous body of the implant which is treated with ZirTi surface. The Prama implants are available with fully machined surface. ZirTi Gold Machined Surface (Zirconium Sand-Blasted Acid Etched Titanium) The machined neck allows a perfect control of the connection diameter and prevents the plaque accumulation on the connection with the post;...

Machined surface The Prama implants are also available with fully machined surface. The machined neck allows a perfect control of the connection diameter and prevents the plaque accumulation on the connection with the post, moreover, the particular roughness given by the machined neck allows a great adherence of the connection fibers. The roughness of the machined surface is suitable for a correct osteointegration process, as documented by 30 years of clinical evidence. Graphic reproduction The presence of the machined surface on all the coronal part of the implant allows freedom in the...

Connection The Prama implants are available in three different nominal diameters, 3.80 mm, 4.25 mm and 5.00 mm, joined by a single connection diameter, 3.40 mm. In this way the surgical and prosthetic management is simplified, as well as the storehouse of prosthetic components needed by surgeon and laboratory. Collex The Prama implants have the Collex connection, already present in the Premium, Kohno and Shelta systems. 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...

Contracone seal One of the key factors in determining the success of an implant prosthetic rehabilitation is the absence of bacteria infiltrations; to achieve this aim there must be no spaces between the platform of the implant and the abutment’s edge, where bacteria could penetrate and give rise to anaerobic proliferations which are dangerous for the peri-implant tissues. Sweden & Martina have patented a particular micromechanical process which makes conical both the implant’s edge and the post’s one: in this way a mechanical barrier is created, which guarantees a peripheral seal that is...

Prosthetic screw with Full Head technology The prosthetic screw for the Prama posts have been specially studied in order to allow a wide freedom of angled posts personalization. As a matter of fact the head of the screw is full and presents an external hexagon of reduced dimensions compared to one corresponding prosthetic screw with internal hexagon. The head of the screw presents a conical support which improves the prosthetic tightening without impeding its removal. For the screwing and unscrewing manoeuvres of this particular prosthetic screw, dedicated screwdrivers are available, made...

Pre-made posts The Prama angled and straight pre-made posts have been designed together with the screws with Full Head technology. These screws, with their full head and conical support, guarantee stability and resistance to the prosthesis, and allow the dentist to have the maximum freedom of customising in accordance with the B.O.P.T. protocols. The pre-made posts have been designed specifically to grant continuity with the transgingival neck with Prama hyperbolic geometry. This absence of sharp edges will allow to the mucosa to flow on titanium without obstacles and to reach the...
