Guided Tissue Regeneration is most effective for which type of furcation?

• A. Class 1 furcations
• B. Class 2 furcations
• C. Class 3 furcations
• D. Class 4 furcations

Answer: (B)

Guided Tissue Regeneration (GTR) is primarily utilized to encourage the regeneration of periodontal tissues that have been lost due to disease or trauma. In the context of furcation involvement, Class 2 furcations represent a moderate degree of tissue loss where there is still some intra-radicular bone present, making it possible for regenerative techniques to be employed effectively. The use of GTR in Class 2 furcations is advantageous because it allows for the placement of barrier membranes that promote the regeneration of lost periodontal tissues, including bone and attachment, while preventing the growth of undesired epithelial cells that could impede healing. This method is helpful in stabilizing the furcation area and restoring function. In contrast, Class 1 furcations show minimal loss of attachment and usually do not require regenerative techniques, Class 3 furcations exhibit more extensive loss where the furcation is open through to the opposite side, making it more challenging to achieve effective regeneration, and Class 4 furcations are similar but with complete exposure to the oral cavity, leading further complications for regeneration. Thus, GTR is most effective in addressing Class 2 furcations, where there is enough supportive structure remaining to facilitate successful regeneration.
