What best describes the goal of GTR in periodontal therapy?

The goal of Guided Tissue Regeneration (GTR) in periodontal therapy primarily focuses on regenerating lost alveolar bone and periodontal structures that may have been compromised due to disease. GTR employs a barrier membrane to selectively promote the growth of periodontal ligament and bone cells while preventing the growth of faster-healing epithelial cells. This targeted approach aims to facilitate the restoration of the attachment apparatus surrounding the teeth, enhancing the potential for successful periodontal healing and regeneration.

Although other choices touch on aspects relevant to periodontal therapy, they do not encapsulate the specific therapeutic aim of GTR as accurately. For instance, while creating a barrier for cell growth is part of the GTR process, it is not an end goal but rather a means to achieve the ultimate objective of regenerating lost tissues. Similarly, reducing pocket depth and improving blood supply are important outcomes in periodontal therapy but do not specifically define the unique intent of the GTR technique.
