Resumen
CARRASCO CARRASCO, O et al. Functional efficiency of patients rehabilitated with implant-retained overdentures compared whit conventional total prosthesis. Av Odontoestomatol [online]. 2018, vol.34, n.4, pp.199-207. ISSN 2340-3152.
Introduction:
The purpose of this study was to determine the retention and functional efficiency of total prosthesis when retained by Ticare Inhex implants (Mozo-Grau, Valladolid Spain) and ball attachments, through the Nakamura test, in elderly subjects.
Materials and methods:
The sample included total maxillary and mandibular edentulous subjects. Retention and electromyographic activity were recorded by electrodes located bilaterally in the anterior temporal and superficial masseter muscles, applying Nakamura test. Normality and Wilcoxon nonparametric tests were used to check the distribution of two related samples, SPSS 19.0.
Results:
Retention increased significantly, in electromyographic activity during masticatory function, an average of 42.19 mv was obtained for the Temporals and 33.89 mv for the masseters with the use of conventional prosthesis, and an average of 56, 48 mv and 48.20 mv respectively, with the use of implant-retained overdentures.
Conclusion:
in patients with implant-retained overdentures the retention and electromyographic activity increased for the anterior temporal and superficial masseter muscles improving their masticatory efficiency.
