Apically Positioned Flap - CDT Code Guide
Overview
CDT Code D4245 refers to the apically positioned flap procedure, a surgical technique primarily used in periodontics to manage and preserve keratinized gingiva. This procedure is crucial when performing osseous resection and during the second stage of implant procedures. It is also utilized in the surgical exposure of labially impacted teeth and in the treatment of peri-implantitis. The apically positioned flap helps maintain the integrity of the gingival tissue, ensuring that the keratinized/attached gingiva is preserved, which is vital for both aesthetic and functional outcomes in dental treatments.
