Comparative evaluation of the effect of surface treatment of fiber-reinforced posts and prefabricated metal posts on adhesion of a resin-based luting cement: An study.

Background: The purpose of this study was to evaluate the effect of surface treatment of fiber-reinforce post and metal post of adhesion of a resin luting cement.

Materials And Methods: Sixty methyl methacrylate specimens were fabricated with a customized metal rod. The samples were segregated into six groups (F1, F2, F3, M1, M2, and M3) of 10 specimens ( = 10) each.

The influence of thread geometry on biomechanical load transfer to bone: A finite element analysis comparing two implant thread designs.

Background: The success of dental implants depends on the manner in which stresses are transferred to the surrounding bone. An important consideration is to design an implant with a geometry that will minimize the peak bone stresses caused by standard loading. The aim of this study was to assess the influence of implant thread geometry on biomechanical load transfer and to compare the difference between two different thread designs.
