Temporomandibular disorders are a group of conditions affecting the temporomandibular joints, the jaw muscles, and related structures. Patients with temporomandibular signs and/or symptoms frequently present with indications for prosthetic treatment. The management of these patients aims to achieve patient comfort, occlusal stability, and the complex restoration of the teeth. The goal of this review is to provide an overview of the relationship between prosthodontics and temporomandibular disorders and/or bruxism with a focus on the cause-and-effect implications and the strategies for planning prosthetic treatments in patients with temporomandibular disorders and/or bruxism.

Prosthodontic Treatment in Patients with Temporomandibular Disorders and Orofacial Pain and/or Bruxism: A Review of the Literature

Tooth Repair and Regeneration: Potential of Dental Stem Cells.

Purpose Patients in need of extensive prosthodontic treatment may need restoration of their occlusal vertical dimension (OVD) due to tooth wear, tooth loss, or changes that have occurred to existing prostheses over time. Prosthodontic treatment is based on the clinical application of the available evidence regarding interocclusal distance (IOD), the positional stability of rest vertical dimension (RVD), and the effect of altering the OVD. Hence, the purpose of this consensus document is to examine available data related to IOD, RVD, and alteration of the OVD. Materials and methods The search was limited to Clinical trials, Randomized Controlled Trials, Systematic Reviews and Meta-analyses. Key words were healthy patient, mean, range, interocclusal rest distance; healthy patient, mean, range, freeway space; and dentistry, interocclusal gap, and no citations appeared. Dentistry, interocclusal distance, revealed 5 not relevant citations. Dentistry, inter occlusal rest space, and dentistry, interocclusal rest distance, both had the same single not relevant citation. Dentistry, freeway space revealed over 7,000 citations. Dentistry, occlusal vertical dimension, revealed 253 citations, 7 of which were related to the search question but only 1 which was different from the previous search. Mandible, rest vertical dimension, age changes, found 7 citations, none relative to the question. Expanding the search to include journal article found 260 citations with only one relevant to the question. Mandible, rest vertical dimension, alteration, harm revealed no citations; mandible, occlusal vertical dimension, alteration, revealed 15 citations, 1 of which was relevant; mandible, occlusal vertical dimension, changes, revealed 75 citations, none of which were relevant; mandible, occlusal vertical dimension, rehabilitation revealed 10 citations, none of which were relevant. Expanding the search strategy to include Journal article, mandible, occlusal vertical dimension, alteration, received 159 citations, 4 of which were relevant; mandible, occlusal vertical dimension, restoration revealed 208 citations, 1 of which was relevant. Numerous other articles were culled by going through the reference lists of the aforementioned articles. Results For IOD, 27 articles were found relevant to the search question, which confirmed a mean of 3.0 mm with ranges from 1 to 9 mm. Five articles revealed little evidence as to whether the RVD changes during life. For OVD, 20 articles, including 4 systematic reviews, revealed some evidence that skeletal growth continues from mid adolescence into mid adulthood; strong anecdotal evidence that some unopposed teeth will continue to erupt; no clinical evidence to support the concept that abraded teeth in occlusion in a patient with bruxism will undergo continuous eruption; and some evidence from clinical case reports that restoring OVD in patients with severe abrasion is a successful treatment. Conclusions There is a range of dimensions for the interocclusal distance (IOD) with many normal dental patients functioning with a higher or lower IOD than the commonly used 3.0 mm average dimension. The resting vertical dimension (RVD) is a 3-dimensional range with little evidence related to changes in the RVD during life. However, aging can cause a decrease in muscle tone which could affect the RVD. The restoration of the OVD can be successfully accomplished if proper diagnosis and treatment planning are performed.

Occlusal Vertical Dimension: Best Evidence Consensus Statement.

The rates of head and neck cancer increase each year, with men, smokers and those with low purchasing power being the most at risk. Although there is no dental treatment in the literature before defined antineoplastic therapy, tooth loss as a consequence of therapy and also as a preventive measure continues to affect cancer patients, reinforcing the need for multidisciplinary treatment. This work is a case study, carried out at the University of Santa Cruz do Sul Dental Clinic (UNISC), and its main objective is to investigate how the use of removable partial dentures with ERA® fitting system can functionally and aesthetically benefit the patient. patient when well indicated. Clinical care took place during practical dental care activities, where removable dentures removed by the ERA® retention aid system were made. Note the patient's satisfaction with the work performed and the correct adaptation, followed by good retention, aesthetics and especially functionality. Thus, it was concluded from this case study that oral rehabilitations with removable partial dentures retained by ERA® locking system are a viable and less expensive option for patients with tooth loss after cancer treatment.

Reabilitação oral de paciente com histórico de Carcinoma de Hipofaringe : estudo de caso.

Part one of this article considered the theoretical and clinical aspects of recording centric relation using established techniques, and presented a range of methods available all with advantages and limitations. This second article will consider more recent concepts in recording centric relation and practical aspects of increasing the occlusal vertical dimension.

Centric relation and increasing the occlusal vertical dimension: concepts and clinical techniques - part two.

Changing the occlusal vertical dimension (OVD) has been one of the most controversial issues of restorative dentistry. The modification of the OVD may be indicated whenever it is necessary to harmonize dentofacial esthetics, provide space for planned restorations, and improve occlusal relationships. The OVD should not be considered an immutable reference, but rather a dynamic dimension within a zone of physiological tolerance that can be altered as long as the dentist respects the envelope of function. However, vertical changes in the relationship between the maxilla and mandible may have some biological, biomechanical, esthetic, and three-dimensional (3D) functional implications because the initial references of maximum intercuspation and anterior tooth relationships must be reconstructed and adjusted in a new dimension of space. This article aims to present a critical review of the relevant OVD literature and provide the clinical objectives and subjective parameters necessary to guide the clinician and laboratory technician during treatment involving OVD alterations.

Occlusal vertical dimension: treatment planning decisions and management considerations.

Los cambios en la dimension vertical de la oclusion (DVO) han constituido uno de los temas mas controvertidos en la odontologia restauradora. La modificacion de la DVO puede estar indicada siempre que se haga necesario armonizar la estetica dentofacial, proporcionar espacio para las restauraciones planificadas y mejorar las relaciones oclusales. La DVO no debe considerarse como una referencia inmutable, sino como una dimension dinamica dentro de una zona de tolerancia fisiologica que puede modificarse siempre que el odontologo respete el marco de funcional. Sin embargo, los cambios verticales en la relacion entre el maxilar superior y la mandibula pueden tener ciertas implicaciones biologicas, biomecanicas, esteticas y tridimensionales (3D) funcionales debido a que han reconstruirse las referencias iniciales de intercuspidacion maxima y las relaciones dentales anteriores y adaptarse a la nueva dimension de espacio. El objetivo de este articulo es presentar una revision critica de la bibliografia relevante sobre la DVO y aportar parametros clinicos objetivos y subjetivos para guiar al clinico y al protesico dental durante los tratamientos que implican una modificacion de la DVO.
