The technician proceeded with the construction of the bar and the acrylic prosthesis with a good hygienic mucous (Figs. 27–29). The provisory prosthesis was then replaced by the defin- itive one with the occlusal extended to the first mo- lar (Figs. 30 & 31). The support of the soft tissues given by the vestibular flange of the upper prosthesis provided a correct vertical dimension and also the healing of the cheilitis that affected the patient before the treatment as well as the protrusion of the lips and a mechanical lifting of the wrinkles (Figs. 32–35). The orthopantomography six months after the treatment confirms the stability of the im- plant restoration (Fig. 36). Fig. 31 Conclusion Total and partial edentulism is a serious handicap for people who are affected. Edentulism is often - times a self-made problem, beginning early with a careless oral hygiene and unfavourable habits. Thus, as dentists we should encourage our patients at a very early stage of age to follow a healthy lifestyle, includ- ing personal hygiene, nutrition, physical activity and regular dental check-ups from elementary school on, involving of course the families. At the moment a person becomes edentulous however, it is our duty to try to improve the quality of his life in restoring his proper chewing function (not to further jeopardise the state of his health) and to improve his social life (not to compromise the psychological situation).
