Management of Severe Atrophy with a Customised Subperiosteal Implant in the Posterior Mandible

Clinical trials and follow-ups have provided ample documentation of the adaptability and predictability of endosseous implants (1). Patient general health state, bone availability and long osseointegration durations could have been limitations to the use of this implants. Subperiosteal implants with proper design can work effectively for many years and are a good substitute for endosseous implants, according to research findings (2). With the use of digital technology, clinicians can design the implant based on the patient's cone beam computed tomography (CBCT) scan well in advance of surgery, addressing the drawbacks of analogue subperiosteal implants, which included the possibility of implant misfit due to impression material contraction and more significant trauma to the patient requiring two surgical interventions rather than one.This case study discusses the design characteristics of 3D printed superiosteal implants, the step-by-step procedure and their unique features based on recent research conducted in Romania with AB Dental International (3).
