STATEMENT OF PROBLEM Understanding is needed regarding the effect that occlusal interferences have on the teeth, periodontium, and especially on jaw function. PURPOSE This article summarizes research in which experimental occlusal interferences have been placed on the teeth of animals and human volunteers. MATERIAL AND METHODS Data from 18 human and 10 animals studies were reviewed. Experim...

A more refined diagnosis tends to be based on subtle signs and symptoms, requiring the specialist to be extremely judicious and knowledgeable. Occlusal trauma should be included in the differential diagnosis of apical periodontitis and dental trauma. Ideally, when a tooth presents with pulp necrosis and signs of occlusal trauma, one should conduct the interview and diagnostic tests in search of...

objective(s): occlusal trauma is one of the most common forms of oral biting dysfunction. long-term occlusal trauma could weaken the stomatognathic system; especially damage one’s masticatory muscle. through using the rat model, this study investigated the trophic effect of ciliary neurotrophic factor (cntf) on injured masseter muscle. materials and methods: male wistar rats (n=36) were randoml...

STATEMENT OF PROBLEM Biomechanics of occlusal force and indirect calculation of temporomandibular joint loading in patients after surgery for head and neck cancer is poorly understood. PURPOSE This study compared occlusal force values of 6 mandibulectomy subjects with reconstructed mandibles to 6 noncancer subjects with intact mandibles and reports occlusal force predictions from a developed ...

OBJECTIVES To establish a three-dimensional (3D) finite element (FE) model of a maxillary first premolar and to evaluate the stress generated on the tooth (dentine) and on the indirect composite resin restorations by occlusal forces. METHODS An embedded intact maxillary first premolar tooth was sliced serially and scanned digitally parallel to the occlusal surface. The 64 images were assemble...

OBJECTIVES To investigate the relation between occlusal loading and peri-implant clinical parameters (probing depth, bleeding on probing, gingival retraction, width of keratinized mucosa, and crevicular fluid volume) in patients with implant-supported complete fixed prostheses in both arches. MATERIAL AND METHODS This clinical study took place at the University of Valencia (Spain) dental clin...

BACKGROUND Although the discrepancy between the habitual occlusal position (HOP) and the flat bite plate-induced occlusal position (BPOP) (regarded as the muscular physiological reference position) has been recently reported to be related to symptoms of temporomandibular disorders (TMDs), it still remains unclear whether the occlusal equilibration in the reference position is effective to resol...

PURPOSE To describe the occlusal pressure redistribution in dental arches following placement of single posterior implant-supported restorations in occlusion with natural dentitions. MATERIALS AND METHODS Fifteen patients who presented for successfully osseointegrated single posterior implant restorations participated in the study. Cement-retained, all-ceramic implant crowns were fabricated a...
