Sensations and trigeminal somatosensory-evoked potentials elicited by electrical stimulation of endosseous oral implants in humans

摘要: Abstract The perception of bipolar electrical stimuli through implants was studied. were delivered to permucosal oral endosseous in 15 individuals, who then reported tapping beating sensations. In 10 out the 15, these evoked clearly distinguishable potentials averaged electroencephalograms. most prominent scalp potential a positive wave with latency between 18 and 25 ms, often preceded by negative around 12–17 ms. contrast, when motor response elicited stimulation lip, shorter 8–11 ms found additionally, indicating that former-mentioned waves represent true sensory not an artefact myogenous origin. Furthermore, topical anaesthesia gingiva surrounding six individuals had little effect on responses. This evidence excluded peri-implant mucosal innervation as origin somatosensory-evoked implants. To best our knowledge, for first time sensation (osseoperception) has been correlated simultaneously recorded trigeminal (TSEPs).
