Abstract

Svrha istraživanja: Sagitalni nagib kondilne staze i Bennettov kut glavni su
parametri za programiranje zglobnih mehanizama prilagodljivih dentalnih
artikulatora koji su nužni za simuliranje položaja i kretnji donje čeljusti. Svrha
istraživanja bila je ispitati postoje li značajne razlike između dviju metoda mjerenja
nagiba kondilne staze i Bennettova kuta u odnosu na tri različita artikulatorska
sustava.
Materijal i metode istraživanja: U istraživanju je sudjelovalo 30 asimptomatskih
(15 ženskih i 15 muških) mlađih ispitanika (dobi 25,7 ± 2,9 godina) s normalnom
okluzijom. Svakom ispitaniku uzeti su anatomski otisci obje čeljusti na osnovi kojih
su se izradili radni modeli iz tvrde sadre. Za mjerenje vrijednosti lijevoga i desnog
sagitalnog kondilnog nagiba i Bennettova kuta koristilo se dvjema metodama
(voštanim ekscentričnim registratima i uređajem Arcus Digma) u cilju namještanja
navedenih parametara u tri različita artikulatora (SAM 3, Protar 7 i Artex CR).
Rezultati: U ispitivanom uzorku prosječne vrijednosti nagiba kondilne staze i
Bennettova kuta bile su značajno veće kod metode s voštanim ekscentričnim
registratima nego kod metode s uređajem Arcus Digma. Prosječne vrijednosti za
nagib kondilne staze iznosile su od 34° do 41,7° za voštane ekscentrične registrate i
od 28,2° do 34,4° za uređaj Arcus Digma. Bennettovi kutovi iznosili su od 15,7° do
19,7° za voštane ekscentrične registrate teod 9,3° do 9,8° za uređaj Arcus Digma.
Statističke analize (t-test za zavisne uzorke i MANOVA) pokazale su utjecaj dizajna
artikulatorskih sustava i metode mjerenja na osnovi pronađene statistički značajne
razlike prosječnih izmjerenih parametara (p < 0,025).
Zaključak: Unutar ograničenja ovog istraživanja uporaba uređaja Arcus Digma
može se smatrati više pouzdanom i ispravnom za individualizirano programiranje
nego uporaba voštanih centričnih registrata.

Abstract (english)

Purpose: Sagittal condylar inclination and Bennett’s angle are the main parameters
for programming joint mechanisms of adjustable dental articulators that are
necessary to simulate the position and movement of the mandible. The purpose of
this study was to examine whether there are significant differences between the two
methods of measuring the slope condylar path and Bennett’s angle in relation to three
different articulator systems.
Material and methods: The study included 30 asymptomatic (15 female and 15
male) younger patients (age 25.7 ± 2.9 years) with normal occlusion. Each subject
was taken anatomical impressions of both jaws on the basis of which they created
working models of hard plaster. To measure the value of the left and the right of the
sagittal condylar inclination and Bennett’s angle two methods were used (wax
eccentric records and Arcus Digma device) for the purpose of setting the above
parameters in three different articulators (SAM 3, PROTAR 7 and Artex CR).
Results: In our sample, the average value of the condylar inclination and the
Bennett’s angle was significantly higher for the method of wax eccentric records
than the method conducted by Arcus Digma device. Average values for the condylar
inclination were 34° to 41.7° for wax eccentric record and 28.2° to 34.4° for the
Arcus Digma device. Bennett’s angles amounted to 15.7° to 19.7° for wax eccentric
record and 9.3° to 9.8° for Arcus Digma device. Statistical analysis (t-test for paired
samples and MANOVA) showed the influence of articulator system design and
methods of measurement based on statistically significant differences in average of
measured parameters (p <0.025).
Conclusion: With the limitations of this study, the use of an Arcus Digma device
should be considered reliable and valid for individual programming dental
articulators rather than the use of wax eccentric records
