“…They concluded that abutments with a circumferential groove do not lead to a different response of the mucosal margin compared with a regular abutment and they are no more resistant to removal than regular abutments after 6 weeks of function. Finally, Bishti et al recently undertook a systematic review to determine the peri‐implant tissue response to different implant abutment materials and designs, assessing, at the same time, the impact of tissue biotype. The focus of their research included the transmucosal part of abutments, scalloped implants, platform switching and abutment materials.…”

Patient expectations from implant treatment have changed over the years and esthetics plays an important role in defining what is now called success of rehabilitation. Of the many factors that influence the outcome of the rehabilitation, the two main ones are the bone and soft-tissue deficiencies at the intended implant site. Many surgical approaches are described in terms of timing of implant placement and management of regenerative procedures. The aim of this article is to discuss the different implant placement alternatives in the esthetic area, in particular: (i) the timing of implant placement/regenerative procedures/skeletal growth/altered passive eruption; (ii) the correct three-dimensional position of the fixture between the cuspids and in the premolar area; (iii) multiple missing teeth in the esthetic area with single tooth/pontic or cantilevered options/prosthetic compensation; (iv) placement of implants into infected sites; and (v) the influence of abutment and crown morphology on implant position. Combining our long-standing clinical experience and the pertinent literature, the following conclusions can be drawn: Immediate implant placement can be a successful procedure in terms of esthetics but it is technique sensitive and requires an experienced team. Immediate placement is less traumatic to the patient as fewer surgical procedures are involved and patients tend to prefer this clinical approach with regards to quality of life. The diagnostic phase is of utmost importance, with not only bone and soft tissue deficiencies being addressed but also: skeletal growth, dental/implant soft tissue parameters such as altered passive eruption and the morphology of the roots adjacent to the edentulous area. Post-extraction immediate loading is feasible in infected sites. The correct position of the fixture should follow widely accepted guidelines but the abutment morphologies play a role in the vestibular/palatal position of the implant. The long axis of the implant, aiming at the incisal edge of the future restorations, is the most appropriate implant position when a shoulder-less abutment is used and allows a restorative crown morphology with a cervical contour resembling a natural tooth. The use of a shoulder-less abutment gives more space for the tissue to grow compared with the traditional abutment with shoulder finish line.

“…Previous studies failed to show correlations between abutment surface roughness and inflammatory response in the surrounding soft tissue . Long‐term effects on the use of various materials, surface topographies, and designs of the transmucosal part of the implant unit must be studied clinically . More studies are needed to clarify mechanisms involved in soft tissue maintenance.…”

“…The following causes for pathological bone loss have been proposed: microgaps at implant‐abutment connections; remodeling of the biologic width; peri‐implantitis; premature load; and implant crest module design . It was considered that the degree of marginal bone resorption is directly related to the extent of implant‐abutment mismatch . Retentive regions such as microgaps can accumulate biofilms and therefore stimulate peri‐implant inflammatory reactions .…”

Two-piece implant systems are mainly used in oral implantology involving an osseointegrated implant connected to an abutment, which supports prosthetic structures. It is well documented that the presence of microgaps, biofilms and oral fluids at the implant-abutment connection can cause mechanical and biological complications. The aim of this review paper was to report the degradation at the implant-abutment connection by wear and corrosion processes taking place in the oral cavity. Most of the retrieved studies evaluated the wear and corrosion (tribocorrosion) of titanium-based materials used for implants and abutments in artificial saliva. Electrochemical and wear tests together with microscopic techniques were applied to validate the tribocorrosion behavior of the surfaces. A few studies inspected the wear on the inner surfaces of the implant connection as a result of fatigue or removal of abutments. The studies reported increased microgaps after fatigue tests. In addition, data suggest that micromovements occurring at the contacting surfaces can increase the wear of the inner surfaces of the connection. Biofilms and/or glycoproteins act as lubricants, although they can also amplify the corrosion of the surfaces. Consequently, loosening of the implant-abutment connection can take place during mastication. In addition, wear and corrosion debris such as ions and micro- and nanoparticles released into the surrounding tissues can stimulate peri-implant inflammation that can lead to pathologic bone resorption.
