DENTAL TECHNICIANS > PRAMA AND THE ROLE OF THE DENTAL TECHNICIAN
The main difference between Prama and a prosthetic approach with a predefined margin is a greater involvement of the dental technician in the creation and positioning of the finish line in what I have codified as the “finishing area”1 and the development of the prosthetic emergence profile. This is even more evident in implant-prosthodontics with Prama implant: no longer will manufacturers impose a design of premade posts in a line, now dental technicians can design the post with the crown, whether its end closes on the post or it extends to the implant neck.
Furthermore, the design of the implant neck will make the technician's contribution even more critical. The positioning of the prosthetic margin and the resulting anatomical shape of the crowns are decisive for the success of the prosthetic implant depending on where they are positioned, on the post, on the implant neck or on both.

For this reason, communication is the primary key to maintaining synergy between the laboratory and the clinician. Through their sharing the therapeutic plan, the design that most facilitates the achievement of aesthetic success can be selected among the many components for screw-retained or cemented prosthetics, without having to make up for any possibly overexposed positioning.
The role of the dental technician has also become fundamental when using Prama in situations other than for the aesthetics of a single crown. Actually, from the beginning, dental technicians have maintained that by exploiting the high platform and the convergent neck, the restoration of entire arches would be very easy. The Toronto prosthesis, the All-on-Four method or the conometric concept for full arch restoration, or even the overdenture with locator, all become more easily achieved solutions when working far from the bone and with a profile like the Prama neck.
