Customised instrument to retract alveolar subperiosteal flap during the placement of dental implants: new technique

Retraction of subperiosteal flaps on the buccolingual aspect of the alveolar ridge is important for the proper insertion of dental implants. The width and height of alveolar bone should be felt clearly to prevent misdirection of the implant or penetration of bony walls.1 Recently the Thudichum nasal speculum was described for retraction during the procedure,1 and here we describe a self-retaining instrument that we designed to retract the alveolar subperiosteal flap.
