The atrophic edentulous alveolus. A preliminary study on a new generation of subperiosteal implants
Abstract
The aim of this cohort case series is to present a new subperiosteal implant device that uses CAD-CAM technologies together with 3D metal printing capabilities to produce direct bone-anchored dental prosthetic solutions for the management of atrophic edentulous alveolus and jaws. The clinical experience of 21 subperiosteal devices implanted over a 4-year period is presented. The results of this study showed 14 of the 21 cases were successful (66.7%), while 7 cases had complications including exposure of the metal frame (5 cases), mobility of the device (1 case) and 1 case failed for reasons unrelated to the device. Four of the 7 cases were successfully salvaged resulting in an overall success rate of 85.7% (18 /21 cases). This study supports the use of fully customized subperiosteal jaw implants as a simple and reliable alternative for dental rehabilitation of atrophic edentulous cases which would otherwise require bone grafts for conventional fixed dental implant solutions. With more research, the clinical potential for this device is significant as it not only avoids the need for complex and lengthy reconstructive jaw surgery but also allows for the placement of immediate prosthetic teeth at the time of implantation.

These features, along with cranial base anchorage, make the IPS Implants® Preprosthetic a unique dental rehabilitation device for stable restoration in complex cases, distinguishing it from other subperiosteal implants, particularly those produced by laser melting technology.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
