“…The main research focused on establishing protocols that would develop the ideal prosthetic plan for each clinical case [1,2,8,9]. Thus, studies on the rehabilitation of partially edentulous patients, using single and multiple prostheses, as well as the development of over dentures attached to the implant, were being developed [1,2,10,11]. Research emerged in the following areas: cemented prostheses, retention and connection of the prostheses to implants, development of new prosthetic abutments, biomechanical studies, tooth and implant connections, force distribution in patients wear ingre movable prostheses, studies of implant materials, and application of previous clinical and laboratorial techniques only used in conventional prostheses [12].…”
