Recording of mandibular movements by an articulator system (panadent quick analyser)

Kretnje mandibule i temporomandibularnih zglobova veoma su složene i opsežne. Te su kretnje uglavnom kontrolirane kretnjama kondila i vođene okluzijskim dodirima i funkcijom žvačnih mišića. Granične kretnje mandibule razlikuju se među pojedincima, ali su kod iste osobe ponovljive. U protetskom se radu kretnje mandibule mogu reproducirati pomoću pantografskih snimanja i prijenosa u artikulator. U ovom je istraživanju vršena registracija protruzivne i lateralnih kretnji mandibule pomoću artikulatora »Panadent«, koji se zahvaljujući prilično jednostavnom sistemu registracije i izmjenjivim kondilnim kučištmia ubraja u poluprilagodljive artikulatore. Uz pomoć tog artikulatora relativno je lako moguće registrirati kretnje mandibule i kondila pojedinca. Registracija je izvršena na uzorku od 8 ispitanika. Bez većeg utroška vremena registrirane su kretnja mandibule i kondila i na osnovi registrata prosuđivano je, da li kod pojedinca postoje disfunkcijske smetnje koje otežavaju izvođenje kretnji. Precizno registrirane kretnje mandibule i kondila moguće je prenijeti u artikulator, simulirati laboratorij i na taj način koristiti za dijagnosticiranje okluzijskih smetnji i planiranje i izradu protetskih nadomjestaka.The movements of the mandibula and temporomandibular joints are complex and copious. These movements are mainly controlled by the movements of the condyli and lead by occlusal contacts and the function of the muscles of mastication. The marginal movements of the mandibula differ from individual to individual, but are repeatable in the same subject. In dental prosthetics the movements of the mandibula can be reproduced by means of pantographic recordings and transfer into the articulator. In this study the protrusive and lateral movements of the mandibula were recorded using a panadent articulator, which, thanks to its relatively simple system of recording and exchangeable condyle housings, belongs to the semi-adjustable articulators. By means of this articulator one can record relatively easily the movements of the mandibula and condyli. Recordings were done in a group of 8 examinees. The movements of the mandibula and condyli could be recorded in a short period of time and the records were used to determine whether or not dysfunctional disturbances impeding proper movements existed. Precisely recorded movements of the mandibula and condyli can be transferred into an articulator and simulate laboratory conditions. This enables diagnosis of occlusion disorders and planning of the production of prosthetic substitutes
