Abstract

The purpose of this prospective registry case-series study was to determine the biological, mechanical, and aesthetic improvements made to the additively manufactured sub-periosteal jaw implant (AMSJI) after timed installation. A total of nine patients received maxillary AMSJIs in three sessions over a 2-year period. Architectural changes, topological optimization, and amendments to biofunctionalization were performed after each phase through the use of computer-aided design, finite element analysis, and growing clinical experience. Biological improvements included sandblasting (large grit alumina) and acid-etching; increased hydrophilicity by plasma surface activation; deletion of the crestal connecting struts; relocation of the anterior post in front of the anterior part of the basal loop; protection of the Schneiderian membrane from fixation screw penetration; high polishing of the posts; major platform switch with equigingival connections; the use of removable posts that require local anaesthesia and do not inflict major biological damage; scaffolding for secondary stability; and the provision of an incision guide. Mechanical improvements included the creation of a generic design based on finite element analysis and the resulting topological optimization, a shortening of the wings, and a reduction in the number of fixation screws. Aesthetic improvements included relocation of the anterior post, as described above, and pink anodization of the posts.

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.
