The aim of the study was to analyse the reports on occlusion of implant-supported restorations in terms of their load time (immediate, delayed), type of restoration (fixed, removable), size of implants (length, width), their splints and type of deposition (cementing, screwing). The study reviewed the English language literature from two medical databases: PubMed and Scopus from 01/01/2005 to 31/12/2018. The search terms were: “implants occlusion”, “occlusal scheme implants”, and “occlusion and implants”. On the basis of the titles of papers from 285 items, 86 were selected for further analysis, including 81 from the PubMed database and 5 from the Scopus database. After reading the contents of the articles, 16 papers, which concerned the issue of occlusion in prosthetic rehabilitation with implantoprosthetic methods, were selected. No papers assessed occlusion of implant-supported restorations. What is assessed is the extent of implant load, not the type of occlusion used. In the protocol of immediate implant loading it is important to assess the initial stabilization of the implant and to perform temporary restorations in the disclusion, which as the osseointegration process progresses, will be corrected to achieve a full functional occlusion. The type of functional occlusion following osseointegration assumes the principles defined for the natural teeth such as cusp-fossa contacts, without premature contacts, oblique loads and the lack of contacts in the mediotrusion. It is necessary to correct the occlusion on control visits due to different tactile sensitivity of implant-based prosthetic restoration and different bone load on implants in comparison with natural dentition. These differences may cause overloading of the implant with all its consequences, including implant loss.
