Functional Effects of Zigomatic Implants-supported Rehabilitation: sEMG Study

Objectives: The aim of this clinical study was to evaluate the muscular function of patients totally rehabilitated with zigomatic (maxillar) and all on four (mandibular) implants, in regard to their maintenance of postural position, compared with those having natural dentition

Methods: The experimental group consisted of 20 patients (10 men, 10 women; mean age 60.6 years) using zigomatic (maxillar) and all on four (mandibular) implants for a period of at least six months. The control group consisted of 20 dentate subjects paired with members of the experimental group according to age and gender. The surface electromyographic (sEMG) activity of the masseter and temporal muscles was recorded at rest (10sec), protrusion (10sec), and right and left laterality (10sec). The RMS of maximum voluntary dental clenching normalized the RMS values of subjects’ postural positions. Inter-group comparisons were made using an independent sample t-test (SPSS 17.0). Significance level was set at P<0.05. 

Results: There were no statistically significant (P>0.05) differences between groups in all evaluated situations

Conclusions: Patients using implants and dentate patients demonstrated similar postural sEMG values, showing that zigomatic implants-supported prosthesis can be considered a good treatment option for oral rehabilitation in edentulous patients.
