Abstract
Statement of problemThe 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. PurposeThe 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 methodsTwelve 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). ResultsNo 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). ConclusionsThe use of precisely calibrated infrared sensors may be a cost-effective option for diagnostic mounting.
