Rehabilitation of atrophic jaws with conventional endosseous implant-supported overdentures and immediate loading protocols still presents a clinical challenge nowadays.Many techniques have been described in the literature to overcome this problem.Reconstructive procedures, such as autologous bone grafting or guided bone regeneration, [1] are often used.However, autogenous bone grafting requires a second surgical site, [2] implying additional morbidity, [3] and immediate loading is not always recommended. [4]uided bone regeneration, particularly vertical, is frequently limited in gain and also associated with possible complications in total atrophic jaws. [5]Both techniques require several months for graft maturation. [6]Alternative techniques for the rehabilitation of atrophic jaws, such as tilted implants [7] and zygomatic implants, [8] appear to provide stable long-term results.Atrophic jaws are associated with anatomical changes, carrying an increased risk of injury to noble structures, thus increasing the needs of specific surgical skills during surgery.Zygomatic implants procedures can be performed under local or general anesthesia, depending on the surgeon's experience and the patient condition.A favorable zygoma bone is essential to support the implant. [8]On the severely atrophic jaw, the use of short implants remains controversial. [9]ther techniques such as sinus lift, [10] inferior alveolar nerve lateralization, [11] or osteogenic distraction [12] present diverse results in the literature.[15] Several protocols have been proposed for subperiosteal implant techniques.Herein, the authors present their experience with an innovative design of custom-made subperiosteal implants that includes areas for endosseous support.
