Abstract

Stabilization of the mandibular position is one of the physiological requirements essential for achieving normal occlusion. It is intrinsically related to the normal function of the temporomandibular joint (TMJ), which influences masticatory movements and phonation, so that this stability must be achieved without TMJ symptoms. Objective data obtained from the K7 System is very useful in clinical practice, when considering where to set the goal for the mandibular position in patients with TMD.

Especially for dentists who use the neuromuscular theory, use of the K7 in occlusal therapy for TMD patients offers significant benefits due to its capacity for dynamic 3D assessments of mandibular movements, rather than focusing on static occlusal contact points. Moreover, advancements in digital dentistry have increased digital scanning with the intra oral scanner and cases of aligner-based orthodontic treatment. Unlike traditional wire-based orthodontics, these digital technologies enable precise diagnosis, facilitating clear treatment plans that are easy to understand both for dentists and patients.

This case report presents application of K7 data to determine the neuromuscular mandibular position for a TMD patient of Class II malocclusion with mandibular retrusion. The treatment involved occlusal reconstruction through digital diagnosis, aligner orthodontic treatment and prosthetic treatment.
