What are the two main types of periodontal surgery?

The two main types of periodontal surgery are resective and regenerative surgery. Resective surgery involves the removal of tissue and structures that contribute to periodontal disease, aiming to reduce pocket depth and eliminate infection. This approach could include procedures like osseous resective surgery or gingivectomy.

On the other hand, regenerative surgery focuses on promoting the body's natural healing processes to restore lost periodontal tissues. This can involve the use of grafts, membranes, or other materials to encourage the regeneration of lost bone or periodontal ligament.

The distinction between these two types of surgery is crucial for periodontal therapy, as they address different aspects of periodontal disease and have different goals. While regenerative techniques aim to restore, resective techniques aim to remodel and stabilize the periodontal architecture. Other choices do not encapsulate the primary focus of periodontal surgery as effectively as the correct answer.
