The treatment with implants of partially edentulous patients involves several prosthodontic and implantological dilemmas. The treatment plan is based on a thorough dental diagnosis and a prognosis for the remaining dentition. In addition, various aesthetic and functional parameters are important, such as smile line, gingival contour, presence of interdental papilla, visible amount of gum when laughing, support of the soft tissues, bone heights and occlusal relationships. The planning may include dental, surgical and orthodontic treatments, in order to create a favourable starting point for treatment with implants.
