In a
digital analysis of chewing, based on feedback principles and preferred optical marker position recognition, the interdependent movement patterns of maxillary and
mandibular teeth are analyzed using bidirectional synchronization of tactile and motion
image acquisition technologies, and their movements are recorded by a camera
system. The camera
system preferably integrates at least two systems, one on the right side of the mouth / face and the other on the left side, or one
system is centered relative to the facial centerline. Each system has at least one (preferably three) camera, including at least one and preferably two
monochrome or color cameras with a minimum resolution of 2.3 Mpx and a
high frame rate of at least 1000 frames per second (FPS), equipped with dedicated
optics / lenses, and at least one high-resolution and low-frame-rate color camera with a minimum resolution of 12 Mpx and a minimum
frame rate of 25 FPS, capable of recording markers (M1) indirectly fixed by positioning patterns, or markers directly / independently (M2 – preferably using IPA technology) affixed to the
veneer surface of the crown of the maxillary natural / artificial tooth, and markers independently affixed to the
veneer surface of the crown of the natural / artificial tooth. Because of the connection between the camera and the trigger card, their operation is synchronized in time and is responsible for recording the position / movement of the upper crown with M1 and / or M2 markings relative to the lower crown with M1 and / or M2 markings, as well as the position / movement of the upper and lower crowns with M1 and / or M2 markings relative to the alveolar bone of the upper and lower jaws and the patient's face with M2 markings, the markings being affixed to facial feature anatomical points. This is all recorded synchronously in video film technology, and then the 3D scans of the upper and lower teeth with M1 and / or M2 markings are stitched into the video film, wherein the scans are obtained through intraoral or extraoral scanning technology. Furthermore, it can convert the repositioning of M1 and / or M2 markers. Movements during patient chewing assessment are recorded by a camera system, and the captured images are transcribed into a
software environment. Digital acquisition of data from the M1 and / or M2 optical markers is submitted for further analysis in the
software environment, enabling the conversion of these marker repositionings into the number of collisions between the upper and lower crowns, on which M1 and / or M2 markers are fixed. This is preferably read by a
tactile device, preferably a tactile
manipulator, to map / control the repositioning caused by these collisions via vibrations at a frequency between 1 and 4 kHz. The above arrangement enables the tracking of the amplitude of height changes in the collision angle, which is above / below 10 degrees between the upper and lower crown pairs with M1 and / or M2 markers, within a set time unit, divided into time intervals, preferably 0.001 seconds. Along the path of each movement phase / chewing cycle, the number of vibrations of the tactile
manipulator during the set time unit represents the contact / collision moments of these crown pairs with M1 and / or M2 markers. The pattern on the crown of the natural / artificial tooth positioned on the
implant consists of two separable components, including a prefabricated external component that extends out of the mouth and an internal component.The external component has at least three markings at its tip. The internal component is individually designed and customized to fit the
veneer surface of the patient's tooth crowns. The digital chewing recorder, located within a single housing, simultaneously records the three-dimensional shape of the face from either the right or left side. Two sets of cameras are located at the two ends of the arched opening, independently or simultaneously recording both sides of the patient's mouth and face, as well as the visual markings M1 and / or M2 fixed to the crowns of the upper and lower teeth. Each camera set includes three cameras spaced at predetermined distances. Each set has two
monochrome or color cameras with a maximum resolution of 2.3 Mbps and a
high frame rate of at least 1000 FPS, equipped with dedicated
optics / lenses, and one color camera with a minimum resolution of 12 Mbps.
