Evaluation of the condylar position in younger and older adults with or without temporomandibular symptoms by using cone beam computed tomographyRecent studies in young adults have questioned the influence of discrepancies between central and maximal intercuspal positions in temporomandibular disorders (TMDs). However, whether this finding was because this type of etiologic agent requires time for the development of changes in the condylar position is unclear.
Determination of the reliability and repeatability of a quantitative occlusal analyzer by using a piezoelectric film sensor: An in vitro studyA digital quantitative occlusal analyzer with claimed lower cost and easier maneuverability has been introduced to replace conventional methods. However, information regarding its performance is scarce.
In vitro study on the influence of postpolymerization and aging on the Martens parameters of 3D-printed occlusal devicesAdditive manufacturing has been proposed for the fabrication of occlusal devices. However, information about the mechanical properties of additively manufactured devices is lacking.
Evaluating temperature increase during the polymerization of dental acrylic resin materials used for the direct fabrication of anterior deprogramming devicesThe polymerization of acrylic resin materials used for the direct fabrication of anterior deprogramming devices results in a temperature increase because of the exothermic reaction. This heat release might cause thermal trauma to the pulp, compromising the tooth’s vitality.
Comparing the mechanical properties of pressed, milled, and 3D-printed resins for occlusal devicesComparisons of the material qualities of pressed, milled, and 3D-printed occlusal devices are sparse, complicating informed decisions on material choice.
Fracture resistance and 2-body wear of 3-dimensional–printed occlusal devicesPolymeric material for 3-dimensional printing can be used to fabricate occlusal devices. However, information about fracture resistance and wear is scarce.
Defining centric relationMultiple definitions of centric relation (CR) have evolved over time that may have created confusion or impeded understanding. A recent attempt to achieve a singular definition by surveying the members of the Academy of Prosthodontics (AP) did not achieve majority consensus.
A hemispherical contact model for simplifying 3D occlusal surfacesCurrently, dental articulators can recreate mandibular movements and occlusal contacts. However, whether virtual articulators can also provide information about occluding dental surfaces, functional movements, and the mandibular condyles is unclear.
Vertical repositioning accuracy of magnetic mounting systems on 4 articulator modelsResearch of the ability of a cast mounted on an articulator on maintaining the identical position of a cast mounted on an articulator after repeated repositioning is lacking, despite the possible effects this may have on the occlusion of a mounted cast.
An in vitro evaluation of the maxillary occlusal plane orientation obtained with an electronic application: A preliminary investigationIn the evaluation and fabrication of dental prostheses, maxillary occlusal plane orientation in the sagittal and coronal planes may affect functional and esthetic outcomes. The accuracy of a recently developed electronic application in transferring this orientation to a semiadjustable articulator has not been evaluated.
Occlusal consequence of using average condylar guidance settings: An in vitro studyA simplified mounting technique that adopts an average condylar guidance has been advocated. Despite this, the experimental explanation of how average settings differ from individual condylar guidance remains unclear.
A survey to determine agreement regarding the definition of centric relationThe definition of centric relation (CR) has been both controversial and divisive, with little consensus.
In vitro effects of acid challenge on incisal/occlusal cupping/crateringThe cause of occlusal/incisal cupping/cratering (depressed dentin surrounded by elevated rims of enamel) has been postulated to be primarily the effect of acid on exposed dentin. It is hypothesized that abrasion, bruxism, attrition, and stress-corrosion may play a secondary role in lesion formation. The primary cause and sequence of occlusal/incisal cupping/cratering remain scientifically controversial.
Numeric simulation of occlusal interferences in molars restored with ultrathin occlusal veneersSelecting material for a minimally invasive occlusal veneer reconstruction concept requires an understanding of how stresses are distributed during functional and parafunctional forces.
The relationship between Angle type of occlusion and recorded Bennett angle valuesThe Bennett angle can be an important parameter to accurately record and program into an articulator during restorative procedures. Few data exist regarding the impact and association of a patient's occlusion types on their recorded Bennett angle values.
Reliability of a visual analog scale for determining the preferred mastication sideAlthough the visual analog scale (VAS) is a simple tool for quantitatively measuring symptom perception, no studies have used the VAS to assess the degree of subjective masticatory laterality.
Influence of dental chair backrest inclination on the registration of the mandibular positionVarying the inclination of the dental chair backrest might alter the distribution of occlusal contact points.
In vitro comparison of the maxillary occlusal plane orientation obtained with five facebow systemsThe sagittal and coronal orientation of the maxillary occlusal plane plays an important role in the esthetic and functional outcome of dental prostheses. The accuracy of contemporary facebow transfer systems in transferring this orientation to semiadjustable articulators has not been quantified.
Reliability of the anterior functional device in recording the centric relations of patients with posterior tooth lossThe recording of centric relations (CRs) in patients with posterior tooth loss is a process that is subject to inaccuracy. A number of techniques and devices, including the anterior functional device (AFD), have been developed in the pursuit of better results.
Cone-beam tomography assessment of the condylar position in asymptomatic and symptomatic young individualsStudies of the condyle-mandibular fossa relationship are common, although the role of this relationship in the development of a temporomandibular disorder remains controversial.
Evaluation of various treatment modalities in sleep bruxismSleep bruxism (SB) is an oral condition that is associated with tooth wear, orofacial pain, and interference with sleep. The most recommended management technique is the use of an occlusal splint. Although the mandibular advancement device (MAD) has shown good results, few well-designed randomized controlled trials are available with which to compare these treatment options. Therefore, an evaluation of the effect of these 2 appliances on SB is needed.
Comparison of the Kois Dento-Facial Analyzer System with an earbow for mounting a maxillary castThe Kois Dento-Facial Analyzer System (KDFA) is used by clinicians to mount maxillary casts and evaluate and treat patients. Limited information is available for understanding whether the KDFA should be considered as an alternative to an earbow.
Comparison of a conventional and virtual occlusal recordConventional methods associated with many processes in dentistry are being replaced by methods that use digital technology. One of these processes is the making of occlusal records for the positioning of casts in a virtual articulator. Conventional interocclusal records and the articulator are being replaced by the virtual occlusal record and the virtual articulator.
