Geckili E, et al. - In this study, the physicians aimed to clinically assess the screwless Morse taper implant-abutment connection type, in which the retention screw is totally eliminated, in terms of stability, success, periodontal parameters, and marginal bone levels after 1 year of function by comparing it with a passive fit internal implant-abutment connection, wherein a space exists between the matching components. They reported that implants with screwless Morse taper and passive fit internal connections displayed comparable technical and biologic results after 1 year of function.
