Objective: To determine whether orthodontically treated patients with cleft lip and palate (CLP) possess a different masticatory function than those of untreated patients with normal occlusion. Design: Occlusal contact area, occlusal force, as well as masseter and anterior temporal muscular activity were measured during maximum voluntary clenching (MVC) tests. Mandibular left and right lateral movements during mastication were also assessed. To further elucidate the nature of masticatory function, especially to determine the rate of abnormal jaw movement patterns, a parametric error index (EI) was set. Finally, masticatory efficiency was evaluated with a glucose sensitive measuring device. Participants: Fifteen patients with CLP who had previously completed the orthodontic treatments required to achieve an acceptable and more harmonious occlusion accepted to volunteer in this study along with 21 untreated patients who already possessed a normal occlusion. Results: Patients with CLP showed a significantly lower occlusal force, reduced occlusal contact area, and decreased masticatory efficiency as well as significantly higher EI value when compared with controls. However, there was no significant difference when analyzing muscle activity, although masticatory efficiency was significantly different between the 2 groups. Despite this result, the scores obtained by the patients with CLP in the masticatory efficiency tests were still in the normal range. Conclusions: Orthodontic treatment for adult patients with CLP provides a satisfactory result for the patients’ masticatory ability albeit significantly less ideal compared with untreated patients with normal occlusion.

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, such that implant occlusal force control is compromised, which can lead to peri-implant tissue loss, breakage of implant restorative components, and de-osseointegration. However, by using the T-Scan technology, the clinician eliminates the subjectivity involved in using articulating paper ensuring the occlusal design of newly installed implant prostheses are optimal improving prosthesis longevity. Examples are presented of how T-Scan force and time data can aid in implant restoration occlusal force control.

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.
