Analysis of Masticatory Cycles using Electromagnetic 3D Articulography
Objectives: Compare masticatory cycles in prostethic rehabilitation patients discharged from the Dental Clinic of Universidad de la Frontera using an innovative 3D method.
Methods: A convenience sample was performed, removable dental prosthesis discharged patients (mean 67,5 +- 5 years) 10 women and 2 men,were contact at the 6 months follow up appointment and presented prosthetic stability, masticatory and phonetics function were preserved.
3 Groups were created: full denture, overdenture and maxilar fulldenture and mandibular partial denture.
An Articulograph 3D AG501® record real-time measurement conected to sensors (spherical volume of 0.014 m3). MATLAB® software was used to run files and obtain data for statistical analysis.
Poselt poligone, frontal and sagital plane was recorded, each one received 3.5 grs. of peanut, verbally the investigator aked to star chewing.
The recording stop when the patient swallow spontaneously.
Results: Differences between groups were non significant in aperture on the frontal view, difference was observed between groups in border movements in the sagital view.
We found that extreme movements are disminished.
Subjects using full denture made 67 to 90 cycles, PPR subjects 30 to 104 and overdenture 42 to 114. Only one subject of group 2, was no able to complete chewing and it maid be related to lack of mechanoreceptors and lost of sensibility described in previous studies.
In the frontal view the smallest area registered was in PRP group 19,79 ± 17,20 mm2 and the biggest area belongs to full denture 30,26 ± 25,23mm2. In the sagittal view, our results show an 9,8 ± 9,01 mm2 in PRP subjects and 9,7 ± 8,79 mm2 in full denture.
Conclusions: this study corroborated in an objetive analysis the alterations described in literature subject suffering edentulism and using dental prostheses.
Masticatory function and range of extreme movements were analyzed using high measurement technology, studies agree to an increased mandibular velocity in opening, besides of an increased masticatory cycles.
Is necessary to continuing investigating in the different forms of dental prostethic rehabilitation including a bigger number of subjects, sample and a control group.
