Which is NOT a purpose of periodontal flaps?

The purpose of periodontal flaps is primarily related to gaining access to underlying tissues or performing procedures that enhance periodontal health. Access for root instrumentation is a key reason for elevating a flap, as it allows practitioners to thoroughly clean root surfaces affected by periodontal disease. Additionally, flaps can be used in periodontal regeneration, where the tissue is repositioned to promote healing and regeneration of lost periodontal structures.

Gingival resection, while not directly related to the traditional goals of periodontal therapy, may be performed using flaps in certain cases and is therefore considered a relevant aspect of flap procedures. However, hard tissue augmentation is not a primary purpose of periodontal flaps. Hard tissue augmentation typically refers to surgical procedures aimed at adding volume or density to bone, such as bone grafting. While flaps may be involved in the surgical process for such augmentations, the flap itself is not intended for this purpose. Instead, it serves to facilitate access or reposition tissues associated with periodontal treatment.
