What is Primary Occlusal Trauma

This chapter addresses the ongoing controversy regarding occlusion's role in the progression of periodontal disease. Occlusal force has been considered a non-factor in the initiation of periodontal attachment loss. However, the absence of a validated measuring device or quantifying method for analyzing the occlusion has contributed to the confusion that still exists in the scientific community today about the relationship between periodontal disease and occlusion. The development of the T-Scan occlusal measurement technology, which is independent of a clinician's occlusal contact force level subjective assessment, may change the scientific opinion about occlusion's role in periodontal disease. This chapter illustrates how the T-Scan 8 system aids in treating patients who have tissue loss and occlusal issues. Notably, after the major etiologic risk factors of periodontal disease have been controlled, adjusting the occlusion with the T-Scan improves healing outcomes resulting in less inflammation, decreased probing depths, and bone level stability.
