Abstract
To evaluate the effect of the SL-type Bioceram screw implant on the masticatory function of lower complete denture wearers, six complete denture wearers were selected. The lower denture was anchored onto the implants which were inserted into the bilateral canine regions three months prior to the experiment. The subjects were instructed to chew a piece of gum, under the following three conditions, and jaw movement by means of MKG and surface EMGs from the bilateral masseter and posterior tempolaris muscles were recorded and analyzed. Mucosa support(stage 1), implant-mucosa-support(stage 2), and implant-mucosa-support with anesthetizing the surrounding structures of the implants(stage 3)were set up as experimental conditions.
It might be pressumed that retention and support of the dentures in stage 2 were markedly improved by anchoring onto the implants, as evidenced by the most clearcut and rhythmical chewing motions kinesiographically and electromyographically.
