Abstract

Optički elektronički obrazni luk je jedan od tipova kinematskog obraznog luka. Obrazni lukovi su naprave pomoću kojih prenosimo informaciju o odnosima gornje i donje čeljusti naspram temporomandibularnog zgloba, a također mogu registrirati kretnje koje izvodi žvačni sustav. Karakteristika ovih obraznih lukova jest njihov princip rada na bazi optičke triangulacije, što
znači da položaj i kretnje čeljusti registrira putem senzornog sustava LED i kamera. Precizan prikaz žvačnog sustava pacijenta bitan je u dentalnoj protetici za izradu protetskih nadomjestaka koji neće remetiti statičku ili dinamičku okluziju pacijenta. Također, neizostavan je dio u otkrivanju patologije žvačnog sustava i postavljanja pravilnog plana terapije. Kinematski obrazni lukovi koriste se za individualizaciju potpuno prilagodljivih artikulatora. Nakon montaže uređaja na glavu kreće se sa snimanjem kretnji. Pokreti koje izvodi donja čeljust registriraju se pomoću odašiljača i senzora integriranih u gornji i donji dio obraznog luka. Navedene se informacije dalje prenose i obrađuju u računalnom programu koji simulira grafički prikaz kretnji zajedno s 3D modelom žvačnog sustava pacijenta. Donja čeljust je jedini pomični dio lubanje. Sustav žvačnih mišića, ligamenata i
temporomandibularni zglob povezuju mandibulu s ostatkom lubanje i lica. Zahvaljujući svojoj jedinstvenoj anatomiji donja čeljust ima sposobnost kretanja u šest stupnjeva slobode (otvaranje, zatvaranje, pomak u lijevo i desno te naprijed i nazad) što znači da je rekreacija tih kretnji u artikulatoru nevjerojatno zahtjevna. Zahvaljujući tehnologiji kinematskih obraznih lukova (pogotovo novijih optičko elektroničkih) i virtualnih artikulatora, vrlo se lako i brzo mogu dobiti vjerni prikazi pacijentove stvarne kliničke situacije te na temelju toga izraditi precizni protetski radovi ili planovi za oralnu rehabilitaciju.

Abstract (english)

The optic electronic face bow is a type of kinematic face bow. Face bows are devices that help us transfer information about the position of the upper and lower jaw in relation to the temporomandibular joint, while also registering movements of the masticatory system. A characteristic of these face bows is its way of working based on optical triangulation, which means that it registers jaw positioning and movements through a sensory system consisting of LED lights and cameras. A precise replica of the patient's masticatory system is essential in dental prosthetics for the creation of prosthetic work that will not disturb the patient's static or dynamic occlusion. It is an indispensable part in detecting the pathology of the masticatory
system and setting up a proper therapy plan. Kinematic face bows are used to individualize fully adjustable articulators. After the device is mounted onto the patients head, we can begin with documenting the movements. Movements
performed by the lower jaw are registered using transmitters and sensors integrated in the upper and lower part of the face bow. This data is then sent and processed in the computer program that later provides a graphic representation of the movement together with a 3D model of the patient's masticatory system. The lower jaw is the only movable part of the skull. A system of masticatory muscles, ligaments and the temporomandibular joint connect the mandible to the rest of the skull and face. Thanks to its unique anatomy, the lower jaw has the ability to move in six degrees of freedom (opening,
closing, moving left and right and forward and backward), which means that the recreation of these movements in the articulator is incredibly demanding. Thanks to the technology of kinematic face bows (especially the newer optical electronic ones) and virtual articulators, it is very easy and fast to obtain accurate representations of the patient's real clinical situation and, based on this, create precise prosthetic works or plans for oral rehabilitation.
