Course on the restoration of occlusal architectonics in the OCTA concept!
By the author of the concept – Jean-Daniel Orthlieb – you will learn to:
– find and set a reference plane
– diagnose and manage muscular-articular dysfunctions using splints
– determine therapeutic and reference position
– manage the VDO
– restore an occlusion on the spheres of Spee and Wilson
– recreate correct anterior guidance.
The course is MUST HAVE for gnathologists, prosthodontists, orthodontists and dental technicians who take care of patients with occlusal disorders and muscular-articular dysfunctions.
The OHI‑S OCTA Concept and Splint Therapy program is best for prosthodontists, orthodontists, restorative dentists, and oral surgeons who want structured, training in occlusal architecture and functional splint therapy.
