removable dental prosthesis splint an occlusal device for nocturnal bruxing partial denture users
Journal of Prosthodontics, 2013Co-Authors: Panagiotis Zoidis, Gregory L PolyzoisAbstract:: Nocturnal bruxing is a Parafunctional Activity of the masticatory system that may create problems for removable dental prosthesis (RDP) users. Such problems may include root fractures, increased mobility of abutment teeth, excessive wear of resin denture teeth, minor connector bending, or denture base cracking. This clinical report presents an occlusal device fabricated for an RDP patient. The device used existing ERA attachments for added retention designed with the intended purpose of protecting the definitive fixed and RDP from damage due to nocturnal bruxing Activity and providing for even distribution of Parafunctional forces.

Frequency of relates of parafunctions in the diagnostic subgroups of TMD according to research diagnostic criteria for temporomandibular disorders (RDC/TMD)
Dental Press Editora, 2008Co-Authors: Branco, Raquel Stumpf, Branco, Carla Stumpf, Tesch, Ricardo De Souza, Rapoport AbrãoAbstract:INTRODUÇÃO: as disfunções temporomandibulares (DTM) podem ser definidas como um conjunto de condições dolorosas e/ou disfuncionais, que envolvem os músculos da mastigação e/ou as articulações temporomandibulares (ATM). Um dos meios usados para o diagnóstico é o "Critério Diagnóstico para Pesquisa em Disfunções Temporomandibulares" (RDC/TMD). Hábitos parafuncionais são aqueles não relacionados à execução das funções normais do sistema estomatognático. O bruxismo é caracterizado por atividade parafuncional noturna involuntária dos músculos mastigatórios, enquanto o apertamento dentário é considerado uma parafunção diurna envolvendo esta musculatura, embora possa ocorrer também à noite. OBJETIVOS: o objetivo do presente estudo foi avaliar a freqüência do relato de parafunções orais diurna e/ou noturna em pacientes com DTM nos diferentes subgrupos diagnósticos do RDC/TMD. METODOLOGIA: foram utilizados dados provenientes de 217 pacientes que procuraram tratamento na Clínica de DTM e Dor Orofacial da Faculdade de Medicina de Petrópolis, sendo avaliados através do questionário e exame físico que compõem o RDC/TMD. RESULTADOS: dos 182 pacientes com DTM estudados, 76,9% relataram algum tipo de parafunção, podendo ser diurna, noturna ou a associação de ambas. A parafunção diurna foi a mais freqüentemente relatada entre os subgrupos de DTM, sendo encontrada em 64,8% dos casos contra 55,5% dos casos com relato de bruxismo. O relato de ambas as parafunções foi constatado em 43,4% dos pacientes com DTM. CONCLUSÕES: considerando cada subgrupo diagnóstico, os relatos de parafunções diurna e noturna foram mais freqüentes nos pacientes com dor miofascial.INTRODUCTION: temporomandibular disorders (TMD) can be defined as a group of painful and/or dysfunctional conditions that involve masticatory muscles and/or the temporomandibular joints (TMJ). One of the methods used to the diagnostic is the "Research Diagnostic Criteria for Temporomandibular Disorders" (RDC/TMD). Parafunctional habits are those not related to the execution of normal functions of stomatognatic system. Bruxism is characterized by nocturnal involuntary Parafunctional Activity of masticatory muscles, while clenching is considered as a diurnal parafunction involving this musculature, although this may also occur at night. OBJECTIVE: the goal of the present study was to evaluate the frequency of relates of diurnal and/or nocturnal oral parafunctions in patients with TMD in different diagnostic subgroups of RDC/TMD. METHODOLOGY: it has been used data from 217 patients that seek for treatment at TMD and Orofacial Pain Clinic of Petropolis Medicine School, being evaluated through questionnaire and physical examination that compose RDC/TMD. RESULTS: from 182 TMD patients studied, 76.9% has related some kind of parafunction, that could be diurnal, nocturnal or both. Diurnal parafunction was the most frequent related among TMD subgroups, present in 64.8% of cases against 55.5% of cases with relates of bruxism. Relate of both parafunctions was verified in 43.4% of TMD patients. CONCLUSION: regarding each diagnostic subgroup, relates of diurnal and nocturnal parafunctions has been more frequent in patients of miofascial pain group

effect of a full arch maxillary occlusal splint on Parafunctional Activity during sleep in patients with nocturnal bruxism and signs and symptoms of craniomandibular disorders
Journal of Prosthetic Dentistry, 1993Co-Authors: K Holmgren, A Sheikholeslam, C RiiseAbstract:Abstract This study was designed to investigate the effects of the occlusal splint on Parafunctional oral motor behavior (grinding and clenching) during sleep in patients with bruxism and craniomandibular disorders. The results revealed that the splint does not stop nocturnal bruxism. In 61% of the patients, wear facets on the splint were observed at every visit (2-week intervals) and in 39%, from time to time. The wear facets reappeared in the same location with the same pattern and were caused mainly by grinding. The extension of the facets showed that, during eccentric bruxism, the mandible moved laterally far beyond the edge-to-edge contact relationship of the canines.

reduction in Parafunctional Activity a potential mechanism for the effectiveness of splint therapy
Journal of Oral Rehabilitation, 2007Co-Authors: A G Glaros, Z Owais, L LaustenAbstract:SUMMARY Interocclusal splints may be an effective modality in the management of temporomandibular disorders (TMD), but there is little evidence regarding the mechanism by which splints work. This study tested the hypothesis that pain reduction produced by splints is associated with reduction in Parafunctional Activity. In a two-group, singleblinded randomized clinical trial, patients diagnosed with myofascial pain received full coverage hard maxillary stabilization splints. Patients were instructed to maintain or avoid contact with the splint for the 6 weeks of active treatment. Patients who decreased the intensity of tooth contact were expected to show the greatest alleviation of pain, and those who maintained or increased contact were expected to report lesser reductions in pain. Experience-sampling methodology was used to collect data on pain and Parafunctional behaviours at pre-treatment and during the final week of treatment. Patients were reminded approximately every 2 h by pagers to maintain/avoid contact with the splint. The amount of change in intensity of tooth contact accounted for a significant proportion of the variance in pain change scores. Patients who reduced tooth contact intensity the most reported greater relief from pain. Splints may produce therapeutic effects by reducing Parafunctional activities associated with TMD pain.
