Properly implemented treatment plan implies adaptation to each individual case. The anatomical and morphological limitations of edentulous and partially edentulous jaws present a challenge for the clinician in the context of establishing an adequate implant position, retention and stabilization of dental restoration. On the other hand, highly aesthetic patient requirements play a significant role in achieving overall satisfaction with implant-prosthodontics treatment. From the perspective of the complexity of implant therapy, the first clinical phase of planning requires detailed sublimation of the criteria that define the treatment plan, among which the most important are: degree of regressive bone remodelling, type of prosthodontic restoration, loading time, type of retention, as well as aesthetic criteria. The ideal position of the implant is an important prerequisite for successful tissue integration. The aim of this paper was to present the complexity of the therapeutic plan based on the collected literature through the analysis of factors related to prosthodontic aspect.
