The purpose of this study was to compare pressure sensory mechanisms associated with implant dentures with both natural teeth abutments and implant abutments which have no periodontal membrane. With the von Frey feather stimulation technique we measured axial tactile sensibility of fourteen subjects with a total of nineteen implant dentures and compared results with those obtained from thirteen conventional bridges, four splinted mandibular posterior teeth, and all splinted mandibular teeth in ten normal subjects. We also measured the tactile sensibility of other prosthetic appliances in subjects with implant dentures. For the fixed conventional bridge, the minimum tactile sensi bility was 9.7 g, maximum was 21.4 g, and the mean was 13.5 g ; for the four splinted teeth the minimum tactile sensibility was 7.6 g, maximum was 12.0 g, and the mean was 9.5 g. When all mandibular teeth were splinted the minimum tactile sensi bility was 9.7 g, maximum was 12.0 g, and the mean was 10.2 g. Valueobtained for the implant denture minimum tactile sensibility were 7.6 g, and the maximum wasover 119.9 g. Twelve of the implant dentures of the nineteen tested had the same tactile sensibility as the conventional bridges. In seven of the eight subjects with an implant denture and another prosthetic appliance there was no difference in tactile sensibility between the implant denture and the other appliance. These results suggest that when the tactile sensibility associated with an implant denture is measured, overall sensation created by the prosthesis must be considered in addition to local stimulation caused by the implants.
