Abstract
Statement of problem
The conventional diagnostic mounting procedure in completely edentulous patients is
time-consuming and increases the laboratory workload. Alternatives like optical scanners
and jaw tracking devices have been documented but have their own shortcomings.
Purpose
The purpose of this pilot clinical study was to assess the suitability of an infrared
sensor scan device in procuring the diagnostic data parameters for completely edentulous
patients.
Material and methods
Twelve completely edentulous participants were enrolled in the study. For each, the
distance between the arches was measured by 2 clinical techniques at 3 common reference
points, M1, M2, M3, for the maxillary arch and m1, m2, m3 for the mandibular arch.
The control group measurements were recorded by using a standard diagnostic mounting
procedure on a semi-adjustable articulator, and the experimental group measurements
were recorded by using an infrared sensor scan device. To convert the analog infrared
sensor output into digital data, the Arduino ADC software program was used. The data
from both study groups were statistically compared by using the independent t test (α=.05).
Results
No significant difference in variation was found between the mean measurements of
the device and diagnostic mounting (P>.05). The maximum variation recorded by the experimental device was 1.7 mm, whereas
the minimum variation was 0.8 mm (mean 1.25 mm).
Conclusions
The use of precisely calibrated infrared sensors may be a cost-effective option for
diagnostic mounting.
