Objective:
To study the effect of morphological parameters of natural teeth and fixed partial dentures supported by dental implants on the time of occlusion.
Material And Methods:
The study of the morphological parameters of the first right upper and lower molars of natural teeth and fixed partial dentures supported by dental implants in the positions of the first molars of the upper and lower jaws, followed by determination of the relationship between the obtained data and the occlusion time using mathematical and statistical analysis.
Results:
The study of the morphology of the occlusal surface of natural teeth and fixed partial dentures supported by dental implants did not reveal significant differences in the results of measuring the distances between the cusps of the upper and lower first molars, both natural teeth and fixed partial dentures supported by dental implants. However, the angles of the slopes of the cusps and the angles between cusps in natural teeth are sharper than those of artificial crowns.
Conclusion:
According to the correlation analysis in both groups, the relationship between the occlusion time and the morphological parameters of the lower molars was determined; the relationship between the morphological parameters of the upper molars and the occlusion time was not revealed.
