Introduction Nowadays, in dental implantology, it is accepted to believe that conical implant and abutment junction is the strongest and most biologically appropriate connection. This system eliminates micro-motions during the function, distributes load to the entire implant body, ensures proper biological conditions for bone and soft tissue biological width formation around both dental implant and prosthesis, reduces load to abutment screw and has the best antibacterial bone impregnation system and the highest resistance for bending forces [1, 2, 3, 4]. However, in clinical practice, we may face the disadvantages of this connection: extremely accurate prosthesis is required because of the narrow cone connection; it is restricted to load bridge prostheses due to implants screwed in different angulations and bone-level implants increase the risk of biological and mechanical complications due to epithelial reinvasion [5, 15]. The solutions to these shortcomings could be segmented abutments, loaded immediately after implantation. Other benefits of using these abutments have been noted, such as easier passive prosthetic fit, different stress distribution and biological benefits due to reduced biofilm infiltration into implant surrounding tissue [7-19]. Nevertheless, the use of this technique is limited to prosthetic edentulous jaws, avoiding its possible benefits in multiple implants bridge restorations and single crowns. Purpose of this review is analysis of segmented straight and angulated abutments advantages and disadvantages in dental implant prosthodontics. Aim To discuss the use of segmented and angulated abutments in various dental implant prosthetics. Methods Scientific literature review was completed in PubMed, ClinicalKey, Wiley online, ScienceDirect databases using PRISMA selection criteria. The keywords that were used: definitive abutments, one abutment one time, multi unit, segmented abutments, immed[...].
