TL;DR: The purpose of the study was to determine the effect of two occlusal schemes on the temporal and masseter muscles and the length of the roots of the canines and the anatomical structure of the supporting alveolar process gives testimony to nature’s intention as to the function intended.
Abstract: 1states: “When canines are in normal interlocking position, the lateral and forward movement is limited so that when an attempt is made to move the mandible laterally or forward, there is an involuntary reaction when the canines come in contact. The reaction is an immediate break in the tension of the temporal and masseter muscles, thus reducing the magnitude of the applied force. Regardless of how hard the individual tries to tense these muscles, as long as the canines are in contact, it is impossible for these muscles to assume full tension.” He continues: “The length of the roots of the canines and the anatomical structure of the supporting alveolar process gives testimony to nature’s intention as to the function intended. What may appear as trauma as they come in contact is not trauma at all, because when contact is made, muscular tension is involuntarily reduced, thus reducing the magnitude of applied force.” The purpose of our study was to determine the effect of two occlusal schemes on the temporal and masseter muscles. The first occlusal scheme used anterior guidance to eliminate all contact of posterior teeth in eccentric movements. The second occlusal scheme allowed selective posterior occlusal contact in eccentric movements. These occlusal schemes were developed using maxillary occlusal splints.

TL;DR: It is demonstrated occlusal overload on implants may increase the incidence of marginal bone loss and a treatment plan and Occlusal scheme would benefit from a force management approach.
Abstract: The relationship between occlusal overload and peri-implant bone loss remains a controversial topic in implant dentistry. A causal relationship between the incidence of marginal bone loss next to an implant and occlusal overload implies a treatment plan and occlusal scheme would benefit from a force

TL;DR: Two separate computer technologies have been synchronized together, so that an operator can record their separate diagnostic data simultaneously and this synchronization provides unparalleled evidence of the effect occlusal contact arrangement has on muscle function.
Abstract: Current advances in computer technologies have afforded dentists precision ways to examine occlusal contacts and muscle function. Recently, two separate computer technologies have been synchronized together, so that an operator can record their separate diagnostic data simultaneously. The two systems are: the T Scan II Occlusal Analysis System and the Biopak Electromyography Recording System. The simultaneous recording and playback capacity of these two computer systems allows the operator to analyze and correlate specific occlusal moments to specific electromyographic changes that result from these occlusal moments. This synchronization provides unparalleled evidence of the effect occlusal contact arrangement has on muscle function. Therefore, the occlusal condition of an inserted dental prosthesis or the occlusal scheme of the natural teeth (before and after corrective occlusal adjustments) can be readily evaluated, documented, and quantified for both, quality of occlusal parameters and muscle activity and the responses to the quality of the occlusal condition. This article describes their synchronization and illustrates their use in performing precision occlusal adjustment procedures on two patients: one who demonstrates occlusal disharmony while exhibiting the signs and symptoms of chronic myofascial pain dysfunction syndrome, and the other who had extensive restorative work accomplished but exhibits occlusal discomfort post-operatively.

TL;DR: A fresh approach toward the solution of many of the debatable problems in complete denture construction consists of simply recording the extent of the downward and forward mandibular movements made during speech, which automatically restores the patient's original horizontal and vertical overlaps which can be used to control seven factors of occlusion.
Abstract: A fresh approach toward the solution of many of the debatable problems in complete denture construction consists of simply recording, as guided by muscle memory, the extent of the downward and forward mandibular movements made during speech. This automatically restores the patient's original horizontal and vertical overlaps which can be used to control seven factors of occlusion. The values derived by progressive function refinement of this information, through the controlled use of diagnostic treatment dentures incorporating tissue treatment material, and a free running occlusal scheme have been reviewed.

TL;DR: A reduced orovestibular width of the occlusal surface is recommended in unfavorable loading conditions and the chewing of soft food is suggested during the healing period in cases of immediate loading.
Abstract: Purpose The aim of this study was to investigate whether systematic modifications of occlusal features or food consistency are suitable to reduce the loading of implants. Materials and methods Ten healthy subjects, each of whom had a gap in the chewing center (second premolar or first molar) of one lateral dental arch, were provided with fixed partial dentures (FPD) on two ITI implants. Strain gauges attached to the abutments recorded forces in three dimensions. In each person, the original FPD was successively replaced by three FPDs with different occlusal schemes: The first had steep cusps, the second had flat cusps, and the third had the same cuspal inclination as the first but a narrow occlusal surface. Subjects chewed gummy bears and bread as a tough and a soft bolus, respectively. Results In chewing of gummy bears, the mean vertical forces of the three FPDs ranged between 264 and 284 N and were not significantly different. The mean bending moments amounted to 27 Ncm and 24 Ncm with steep and flat occlusal slopes, respectively. With the narrow occlusal surface, the bending moments were reduced by 48%, to a mean of 11 Ncm. Chewing of bread yielded similar relations with lower mean vertical forces and bending moments. Conclusion Narrowing the orovestibular width of the occlusal surface by 30% caused a significant reduction of lateral force components. A reduced orovestibular width of the occlusal surface is recommended in unfavorable loading conditions. In addition, the chewing of soft food is suggested during the healing period in cases of immediate loading.
