Hands-On Dental Course | Level 4

The complex case demands a plan before a procedure. This module teaches you to build that plan: the sequence of correction, the role Phase 1 plays within it, and where the case is going before you place a single appliance. The plan is what the adjustment serves; without the plan, the orthotic has no defined objective.

The orthotic is not a default, and not every complex case calls for one. This module teaches the indication: which findings call for repositioning the mandible with an orthotic, and which call for another route. Knowing when not to use an orthotic is as much a part of the skill as knowing when to use one.

An orthotic is only as good as the position you adjust it to, and it resolves pain and permits the joint to heal only when that adjustment is carried through completely. The skill is in the adjustment, not in the appliance. An orthotic adjusted to an incomplete position holds the mandible close to where it already was, and the condyle does not arrive at the target.

Material is removed where the mandible indicates, not where it is convenient to reach. That requires you to move the mandible. You guide the patient through the excursive and protrusive slides, recognize when the patient is not producing them, and lead them through until the contacts present themselves. A patient who guards, or who closes into the position they have held for years, will not deliver those marks unassisted. This module teaches how to direct the adjustment: which contacts to remove and in what order, how to move the mandible so the correct contacts appear, and how to verify that the position has been reached rather than approximated.

Reducing acrylic is not adjustment. Knowing where the reduction belongs is.

This module teaches you to determine the target mandibular position the case requires - the corrected position toward the Optimal Physiologic Position - using TENS to locate it and an accurate bite registration to capture it. The position is the objective; everything that follows is how you reach it.

The orthotic carries the occlusion now, and every contact on it matters, in every slide, in every movement. This module teaches you to deliver the orthotic and to read the contacts for location, timing, and force, establishing even, simultaneous bilateral contact, and eliminate all interferences to allow the muscles to fully relax. Uneven or mistimed contacts in any slide hold the mandible away from the target position; correcting them is the adjustment.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.

Articulating paper shows where the teeth touch. It does not show when, or how hard. This module teaches you to use TScan to read the timing and force of the contacts on the orthotic, to identify premature and high-force contacts, and to adjust toward balanced, correctly timed occlusion at the target position.

Guidance determines how the mandible moves against the orthotic, and interferences fight the position you are trying to establish. This module teaches you to build the guidance the case requires and to find and remove the interferences that displace the mandible or provoke parafunction, so that the orthotic reliably reproduces the target position.

This module also defines when the TScan is used and when its output should not be trusted. The instrument measures force distribution and the sequence of contact accurately. It does not tell you where the mandible is. It reports what occurred at the position the patient closed into, and early in therapy that position is neither the target position nor the same position from one appointment to the next.

Used too early, the recording is accurate and the conclusion drawn from it is wrong. A guarding patient delivers a guarded closure. The mandible has not settled. Balancing to that record removes material that will be required once the position stabilizes, and each correction chases a position that is still moving. The patient is adjusted away from the target rather than toward it, and the symptoms that follow are read as a failure of the appliance.

The module establishes the sequence. The position is determined and verified first. Reproducibility is confirmed. The TScan is then used to refine force distribution and timing within that established position. The module also covers the conditions that invalidate a recording - an unstable mandibular position, an actively guarding patient, an uncontrolled head position - and what to do at that stage of treatment instead.

A TScan used at the wrong stage of therapy is the right map in the wrong city. The readings are correct. The destination is wrong.

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.
