“…These similarities encompass the regions of activity, the volume of activated voxels, and increases of signal intensity. A further point worth mentioning is that occlusion accompanies swallowing (49).…”

First published March 14, 2013 doi:10.1152/ajpgi.00456.2012.-Early work on representational specificity and recent findings on temporomandibular joint (TMJ) movement representation raise doubts that a specific swallow representation does exist. Additionally, during cortical stimulation TMJ movements and swallowing show a high overlap of representational areas in the primary motor cortex. It has thus been hypothesized that they overall might share the same neural structures. To differentiate these two movements, we performed a functional MRI (fMRI) study that enabled a direct comparison of functional representation of both actions in the same subject group. Effort during these tasks was controlled by skin conductance response. When balancing effort, we found a comparable neural representation pattern for both tasks but increased resources necessary to perform swallowing in direct comparison between tasks. For the first time, with the usage of fMRI, we demonstrated a representation in the brainstem for swallowing and occlusion. Increased activation for swallowing was observed in bilateral sensorimotor cortex, bilateral premotor and supplementary motor cortex, motor cingulate, thalamus, cerebellar hemispheres, left pallidum, bilateral pons, and midbrain. Peaks of activation in primary motor cortex between both conditions were about 5 mm adjacent. Brainstem activation was found corresponding to the sensory nucleus of the trigeminal nerve, the solitary nucleus for swallowing, and the trigeminal nucleus for occlusion. Our data suggest that cerebral representation of occlusion and swallowing are spatially widely overlapping, differing predominantly with respect to the quantity of neural resources involved. Both brainstem and primary motor representation differ in location with respect to somatotopy and contribution of cranial nerve nuclei.

“…Wear (of a nonabrasive type) at the contact areas may bring the two surfaces closer to each other. 60 Moreover, in an analysis of physiologic tremor and muscle activity, Timmer and colleagues 48 stated that any muscle-controlled movement is accompanied by vibratory micromovement because of the nature of muscle unit contraction. For this reason, it was recommended that the abutment screw be retightened after the initial insertion and periodically whenever possible for verification of proper tautness.…”

“…Intraoral shear forces occur in the last part of the closing phase and in the initial part of the opening phase during mastication as the cusps of maxillary and mandibular teeth slide along one another. 60 Moreover, in an analysis of physiologic tremor and muscle activity, Timmer and colleagues 48 stated that any muscle-controlled movement is accompanied by vibratory micromovement because of the nature of muscle unit contraction. This also applies to the masticatory muscles during mastication.…”

Rigorous efforts have recently been made to reduce the recurrence of implant/abutment joint failure in single-tooth implant restorations. However, the current knowledge about the stability of implant/abutment joints in an external hexagon implant system is incomplete. We reviewed clinical data regarding single-tooth implant treatment with Brånemark implants, specifically the CeraOne abutment system (Nobel Biocare AB, Göteborg, Sweden). In vitro studies on joint stability were systematically assessed. Bending overload and the presence of misfit at the implant/abutment joint interface are the critical mechanical conditions that can make the joint unstable. Appropriate joint fitness and proper alignment of the implant should be assessed, and occlusal adjustment by narrowing the restoration width and flattening cuspal inclination should be applied to avoid bending moments caused by the lateral component of occlusal forces. Sufficient clinical reports of longer duration that evaluate and verify longer-term success of the newly manufactured joint components were unavailable.

“…A telemetric system developed in our laboratory registers occlusal contact in three to five different areas on the same tooth. 7,8 The multifrequency transmitter device used for this purpose is small enough to fit into the space of one missing molar. Some findings regarding the occurrence and frequency of single and gliding tooth contacts during chewing and swallowing and during bruxism are presented here.…”
