Abstract
The relative occlusal force and real-time occlusal contact timing data provided by the T-Scan technology can be used to manage the insertion occlusal force design of implant prostheses, as their long-term survivability is tied directly to their installed occlusal function. This chapter discusses how in daily dental practice, clinicians spend a great deal of time making corrective occlusal adjustments using solely articulating paper as their intended guide. However, current research shows that articulating paper markings do not measure occlusal force, and that dentists poorly Subjectively Interpret the appearance characteristics of the markings, such that implant occlusal force control is highly compromised, leading to peri-implant tissue loss, de-osseointegration, and elevated frequency rates of breakage of implant restorative components. However, by using the T-Scan technology, the clinician eliminates the subjectivity involved in using articulating paper. This ensures the occlusal design of newly-installed implant prostheses are optimal, ensuring prosthesis longevity. Case examples are presented of how occlusal adjustments that employ T-Scan force and timing data with simultaneously-recorded EMG data aid in implant restoration occlusal force control by not only lessening masticatory muscle hyperactivity, but also by improving the muscle tone and length of the face, head, and neck musculature.
