Digital workflow for definitive immediately loaded complete-arch CAD-CAM implant-supported prosthesis in 3 appointments without using intraoral scanning.

This article presents a rapid technique for the accurate transfer of implant positions immediately after image-guided surgery to enable the immediate installation of a definitive complete-arch implant-supported prosthesis with an implant biological width of 3 mm within 3 appointments. A sleeveless copy of the implant surgical guide is magnetically connected to a reference guide to ensure the accurate capture of cylindrical titanium transfer abutments. In the laboratory, the sleeveless guide with the splinted transfer abutments attached is used to generate a definitive cast to be scanned with a desktop scanner. The resulting digital definitive cast is then combined with the original meshes of the prosthetically driven virtual treatment plan to enable a definitive computer-aided design and computer-aided manufactured prosthesis to be fabricated and installed with passive fit.

Clinical Management of Nasal Skin Necrosis Caused by Hyaluronic Acid Filler.

ABSTRACT: Nose augmentation with Hyaluronic acid (HA) fillers has been considered the preferred technique for minimally invasive cosmetic procedures. Despite severe complications related to HA injection are rare, none of the existing treatment protocols has been established as standard. The aim of this report is to present an alternative approach to treat nasal skin necrosis related to HA injection. A high dose of hyaluronidase - 6000 IU was applied in the nose, for the purpose of reversing a necrotic process. The present findings suggest that a high dose of hyaluronidase could be a promising approach to treat severe nasal skin necrosis caused by HA filler.
