Dentists complain almost every day about the occlusal problems with crowns delivered by denture manufacturers! But the most incomprehensible question is: Why are crowns always too high? Occlusal interference: Numerous clinical and research studies have found that 70% of the main causes of occlusal dysfunction are “occlusal interference”. How sensitive are human teeth? The dental nerve can perceive a thickness of 8 microns! Prof. R. Slavicek from Austria has this to say – if our dentists could use jaw frames and face arches in their daily work, they would save 30% of their time. The jaw frame is the patient’s pain-free friend, the best partner of the dentist and the dental technician. And you need them every day for your work. Facial arch: Jaw frame: Transfer table: Dentist: Determine static and dynamic information necessary to obtain joint and maxillary position data! Processing plant: Using static information and dynamic information you can use mean and individual patient dynamic data The relationship of the Bonwill triangle – the basis of the jaw frame: The axis point of the two joints in the mandibular plane, the triangle formed with the anterior incisors is an equilateral triangle with a mean side length: 110 mm and a mean angle of 25 degrees to the horizontal plane. Width of the joints [narrow jaw arch: 95 mm mean jaw arch: 110 mm wide jaw arch: 140 mm mean occlusal plane: 25 degrees ] Mean jaw frame of the upper method: tool for static relationship acquisition – face arch: l. Accurately reproduce the three-dimensional relationship between the patient’s maxilla and the condylar gibbous axis on the jaw frame; 2. Can accurately reproduce the anatomical movement of the patient’s lower jaw for the upper jaw (closed mouth arc); 3. The patient’s study model can be accurately uploaded onto the jaw frame, which makes the communication between doctors and patients and medical technology based on the evidence. l. Left and right anterior condylar guide obliquity; 2. Left and right BENNET movement. Dynamic relationship – condylar (guide) slope The angle between the sliding course along the joint and the horizontal plane during the jaw’s anterior extension or retraction. Dynamic relationship – Bennett’s angle and ISS instantaneous lateral shift generated by Benett’s movement.
