Dynamic navigation and intra-oral photogrammetry for the immediate full-arch rehabilitation of a severely resorbed maxilla: a case report

A 69-year-old female patient with osteoporosis and severely resorbed maxilla presented with unrestorable caries, porcelain fracture, and multiple apical infections on the root-treated abutments of a 10-unit maxillary bridge. The treatment plan comprised bilateral pterygoid implants, incisive canal placement of a wide-diameter implant, and bilaterial tilted implants. The surgery was planned to use Navident EVO dynamic navigation system. Accurate placement of all implants was achieved, including the technique-sensitive pterygoids. High primary stability enabled immediate loading, with photogrammetry used to produce a provisional prosthesis. All implants integrated successfully, with the final restoration fitted 4 months post-surgery. CPD/Clinical Relevance: This is the first documented use of dynamic navigation computer aided dental surgery to facilitate the accurate placement of pterygoid implants in the UK to enable immediate full arch rehabilitation of the severely atrophic maxilla.
