“…The similar bending effect could be caused by the extended width of the implant crown. However, the study did not find an influence between the width of the crown and peri-implant bone loss [42]. Related FEA studies were not found.…”

ObjectivesTo systematically review risks of mechanical impact on peri-implant strain and prosthetic influence on stability across finite element studies.Material and MethodsAn online literature search was performed on MEDLINE and EMBASE databases published between 2011 and 2016. Following keywords tiered screening and selection of the title, abstract and full-text were performed. Studies of finite element analysis (FEA) were considered for inclusion that were written in English and revealed stress concentrations or strain at peri-implant bone level.ResultsThere were included 20 FEA studies in total. Data were organized according to the following topics: bone layers, type of bone, osseointegration level, bone level, design of implant, diameter and length of implant, implant-abutment connection, type of supra-construction, loading axis, measurement units. The stress or strain at implant-bone contact was measured over all studies and numerical values estimated. Risks of overloading were accented as non-axial loading, misfits, cantilevers and the stability of peri-implant bone was related with the usage of platform switch connection of abutment.ConclusionsPeri-implant area could be affected by non-axial loading, cantilever prosthetic elements, crown/implant ratio, type of implant-abutment connection, misfits, properties of restoration materials and antagonistic tooth. The heterogeneity of finite element analysis studies limits systematization of data. Results of these studies are comparable with other findings of in vitro, in vivo, prospective and retrospective studies.

“…38 This conclusion has been expanded for occlusal load in latter investigations. 36,39,40,41,42 Occlusal load, when controlled and associated with implants with no biofilm accumulation results in increased bone density and bone-implant contact, but in the presence of plaque, it may contribute to bone loss. 39,40,42,43 Several clinical studies have also reported a relationship between overload and bone loss around dental implants, 44,45,46,47,48,49 but most of these studies highlighted the presence of microorganisms as the key causative factor or did not investigate a possible correlation with poor oral hygiene, the occurrence of parafunctional habits, and other factors related to prostheses.…”

Implant-based factor as possible risk for peri-implantitis

Peri-implantitis is currently a topic of major interest in implantology. Considered one of the main reasons of late implant failure, there is an emerged concern whether implant characteristics could trigger inflammatory lesion and loss of supporting bone. The purpose of this narrative review is to provide an evidence based overview on the influence of implant-based factors in the occurrence of peri-implantitis. A literature review was conducted addressing the following topics: implant surface topography; implant location; occlusal overload; time in function; prosthesis-associated factors (rehabilitation extension, excess of cement and implant-abutment connection); and metal particle release. Although existing data suggests that some implant-based factors may increase the risk of peri-implantitis, the evidence is still limited to consider them a true risk factor for peri-implantitis. In conclusion, further evidences are required to a better understanding of the influence of implant-based factors in the occurrence of peri-implantitis. Large population-based studies including concomitant analyses of implant-and patient-based factors are required to provide strong evidence of a possible association with peri-implantitis in a higher probability. The identification of these factors is essential for the establishment of strategies to prevent peri-implantitis.
