Hands-On Dental Course | Level 2

Level 2 treats occlusion as a functional system, not a static contact pattern. You will learn to read occlusion in function: the contacts that guide the mandible, the interferences that redirect it, and the relationship between where the teeth meet and where the condyle seats. A diagnosis that omits the occlusion is incomplete, and a treatment plan built on an incomplete diagnosis moves in the wrong direction.

Wear facets are a physical record of how the mandible has moved and where force has been applied. Their angle, pattern, and location indicate the path of function and the sites of concentrated load. This module teaches you to read facets in detail: what a given angle indicates, what a pattern reveals about parafunction, and what both mean for the prognosis of any restoration placed into that environment.

Restorative work fails when it is loaded in ways it cannot withstand. This module teaches you to distribute occlusal force correctly across the arch, to identify where force concentrates, and to design treatment that manages that load so the dentistry lasts.

This module introduces the mechanism behind temporomandibular disorder. Mandibular retrusion leads to condylar distalization, which produces retrodiscal compression and, in turn, disc displacement. Understanding this chain is what allows you to connect a patient's occlusal findings to their joint symptoms rather than treating the two as separate problems.

This module teaches a second reading of the film. Four findings are covered in detail: condylar form and cortical integrity, vertical symmetry of the condyle–ramus unit, antegonial morphology, and the load signature written into the teeth and alveolar bone. Each is tied to the mechanism that produced it and to the clinical decision it changes.

The module also defines the limits of the image. A panoramic radiograph cannot show disc position and cannot establish condylar position or 3-dimensional shape in the fossa. It raises suspicion and directs further imaging. It does not exclude joint disease. Participants learn which findings warrant CBCT, which warrant MRI, and which warrant neither.

You will learn to assess the health of the temporomandibular joint, recognize the signs that indicate dysfunction, and identify what is required to maintain joint health once treatment begins. This establishes the baseline against which appliance therapy and later treatment are measured.

Level 1 established the panoramic radiograph as a record of how the system has been loaded. Level 2 adds the second image and a different question. The panoramic film shows what the load has done. The cephalogram shows the skeletal pattern the occlusion sits in, and the position of the head on the neck at the moment of exposure.

The cephalogram is not a routine record. This module defines the specific indications that justify the exposure, and the protocol that must be followed before the image can answer a postural question. Head position is the controlling variable. An image taken with the head positioned by the cephalostat answers skeletal questions and no postural ones, which is the most common error in how these films are taken.

The interpretation covers craniocervical angulation, cervical curvature, hyoid position, posterior airway, and the sagittal and vertical skeletal relationships, and then connects them to the mandible. The mandible has no fixed skeletal support below. It is suspended between the elevator group above and the suprahyoid and infrahyoid groups below, and the hyoid is anchored downward to the shoulder girdle. Head extension and forward head carriage change the length and direction of pull of that lower group and add a posterior and inferior vector on the mandible. Rest position and the path of closure move with it.

An appliance works by changing where and how the mandible closes. Teeth are the stops that set where the mandible closes and where the condyle seats; an appliance replaces those stops. The orthotic is the only device that moves the condyle in the corrective direction. This module introduces that principle and the place of the appliance within the treatment sequence. Appliance design and delivery are developed in the level that follows.

This module brings the findings together. You will construct the diagnosis from everything gathered: the history and records from Level 1, the comprehensive examination, and the occlusal and functional findings you learn here. You will establish the sequence — what happened, in what order, and what will happen next if the cause is left uncorrected. From that, you will build a treatment plan that addresses the whole system rather than the presenting tooth, sequence it correctly, and communicate it to the patient so that comprehensive treatment is understood and accepted. The plan also accounts for maintenance: what to do to manage and reduce future breakdown once active treatment is complete.
