Abstract
Today, dental implantology is a reliable technique for the treatment of partial and total edentulism. The fixing of dentures on dental implants can be achieved by a number of different techniques. The choice of technique depends on the specific needs of the patient, the condition of the jawbone and the design of the prosthesis itself. Currently, the two most common types of prosthetic abutment connections are cemented or screwed connections, both of which have disadvantages and ad-vantages. The aim of this study is to analyze, with Finite Element Analysis (FEA), a new Cone Morse connection system between the prosthesis and implant. The connection retention has been analyzed by adopting three different approaches: analytical, in vitro and the FEA method. The systems formed by abutment, healing-cap, and crown with three different inclination conditions were modeled in 3D: 0°, 15° and 30°. With Ansys finite element software, the effect of tilt on system retention was studied. The FEA analysis showed comparable results with in vitro studies regarding the retention strength for an abutment-cap system with a taper of 4°, obtaining 66.6 N compared to 68 N calculated through an in vitro study. The inclination of the abutment affects the retention of the system because the hole made on the surface of the abutment, decreases the contact area between the components. The Cone Morse prosthesis implant connection system is the most stable and efficient system compared to the threaded or cemented system. Retention is influenced by factors such as abutment conicity, insertion strength and the contact surface be-tween components.
