Course Description:

The “classical” subperiosteal implant does not enjoy a good reputation; the causes of failure were myriad, as evidenced in the literature. Dahl’s over the mucosa impression technique resulted in a poor fit. The Vitallium frame caused stress shielding and bone resorption. Obwegeser resected the gingiva surrounding the posts, which led to pathological pocket formation, and no screw fixation were used to avoid or minimize mobility of the implant. The frame was not made from titanium, and poor osseointegration and poor soft tissue behaviour resulted. The relationship between the oral microflora and periodontitis was poorly understood in the 1950s and 1960s. When considering the future of implants, it appears justified to reconsider the old concepts in light of the availability of contemporary technologies, such as computer-aided design, softwares and programs design, virtual stress– strain testing, and 3D printing of titanium alloy. With the employment of these modern technologies, the concept of a “high-tech” subperiosteal implant has gradually emerged. Biological design of subperiosteal implant is mandatory for the success of the treatment, guidelines on architectural changes, topological optimization, and biofunctionalization will be explained. This new era of a “high-tech” customized 3D printed subperiosteal implant leads us to consider this technique s a valuable treatment option for atrophic jaws, avoiding more invasive procedures and giving the possibility of immediate loading, improving the patient’s quality of life.
