| Summary: | Orthodontic treatment with Begg technique ussualy caused flaring by using
the multiloop arch wire on lower teeth, and there were not happened on arch wire,
plain wire�multistrand combination. The aim of this study was to compare the effect
of multiloop arch wire and plain wire�triplestrand combination to over jet, over bite
and first molar position on class II div 1 maloclusion first stage Begg technique
treatment.
This study using two groups typodonts on simulation of patient�s jaw with
anterior relation over jet of 7 mm, over bite of 5 mm and class II first molar relation.
First typodont used multiloop arch wire (� � 014� inch), 6 mm height and 2 mm
width. Second typodont used combination of plain wire (� - 016� inch) - triplestrand.
(� � 015� inch) arch wire.
The measurement of 8 sample on maloclution class II div 1 upper and lower
teeth replications carried out at initiation and the end every completion of bathing at
temperature of 40ºC for three minutes and then bathed in the cold water. Every
sample of bathing was repeated for 15 times. Two Ways ANAVA by Repeated
Measured Analysis was used to analyze the data.
The result of this study are:
There were some decreases of the over jet and over bite on typodont I on 15th bathing
(p < 0,01). There was also some decreases of the over bite on typodont II greater
than typodont I on 15th bathing (p < 0,01).
Statistically there was no first molar position on both of typodonts on the upper and
lower jaw.
