Final answer:
A surgical flap approach to periodontal pocket elimination allows for healing by primary intention, retention of gingiva, and access to perform osseous recontouring.
Step-by-step explanation:
A surgical flap approach to periodontal pocket elimination allows for healing by primary intention, retention of gingiva, and access to perform osseous recontouring.
Healing by primary intention refers to the direct closure of the surgical wound, which promotes faster healing and reduces scar formation. Retention of gingiva means that the surgery preserves the gum tissue, preventing further recession. Access to perform osseous recontouring allows the surgeon to reshape the bone supporting the teeth, which is important in treating periodontal disease.
Therefore, the correct answer is **D. All of the above**.
