What is a major concern when attempting positive architecture in severe bone loss cases?

In severe bone loss cases, the major concern when attempting to achieve positive architecture is the potential for jeopardizing the tooth being treated. When there is significant bone loss, any surgical intervention or treatment aimed at regenerating bone or restructuring the periodontium must be approached with caution. This is because aggressive treatments can destabilize the already compromised tooth structure or lead to further attachment loss.

Maintaining the tooth's health and supporting structures is crucial, as aggressive maneuvers might result in additional periodontal issues or even tooth loss. Thus, practitioners must carefully balance the desire to regenerate bone while ensuring the tooth remains viable and stable throughout the treatment process. This concern is paramount when managing cases with severe bone loss, as the risk of further harm to the tooth can outweigh the potential benefits of any restorative procedure.
