Dental implant instrument set and sinus curettes for vertically displacing sinus mucosa to form a space for bone augmentation

摘要

A dental implant instrument set for vertically displacing sinus mucosa to form a space for bone augmentation comprises a bone drill and a sinus curette. The bone drill includes a drill bit for drilling upwardly a hole at a site of the alveolar bone where a tooth is lost, so as to expose sinus mucosa. The sinus curette includes a holding portion and a curette head portion. The curette head portion has one end provided with a turning part for separating from the alveolar bone and displacing the exposed sinus mucosa inward through the hole drilled by the drill bit, so as to form a space for bone augmentation above the site of the alveolar bone where the tooth is lost. The turning part is arranged to be at a first angle between 45 to 135 degrees with the curette head portion.
