This rare case report describes prosthodontic complications resulting from a dental implant was placed surgically more distally in the area of the missing mandibular first molar with a cantilever effect and a crest width of >12 mm in a 59-year-old patient who had a history of bruxism. Fracture of abutment is a common complication in implant was placed in area with high occlusal forces. Inability to remove the broken abutment may most often end up in discarding the implant. Adding one more dental implant mesially to the previously placed implant, improvisation of technique to remove the broken abutment without sacrificing the osseointegrated dental implant, fabrication with cemented custom-made abutment to replace the broken abutment for the first implant, and the use of the two implants to replace a single molar restoration proved reliable and logical treatment solutions to avoid these prosthodontic complications...

INTRODUCTION: Isolated Unilateral Temporalis Muscle Hypertrophy (IUTMH) was first described in 1990, and few cases have been published since then. This disease occurs mainly in adults. There is no clear etiology of IUTMH, but bruxism is one of the risk factors. Only two cases have been described before the age of 20 years. To our knowledge, no cases have been described in persons younger than 15 years old. We report the first case of IUTMH in an 8-year-old and review the literature. MATERIAL AND METHODS: This section is separated into 3 parts: 1- search for and description of clinical cases of IUTMH in our department; 2- literature search to find similar cases; 3- data analysis of all cases found...

The etiology of temporomandibular disorders (TMD), which are considered as a heterogeneous group of psychophysiological disturbances, remains a controversial issue in clinical dentistry. This study aimed to evaluate whether the salivary alpha-amylase (sAA), cortisol levels, and anxiety symptoms differ between children with and without TMD. Initially, 316 young subjects were screened in public schools (nonreferred sample); 76 subjects aged 7-14 years were selected and comprised the TMD and control groups with 38 subjects each matched by sex, age, and the presence/absence of sleep bruxism...

AIMS: To explore whether awake and sleep bruxism interact in their associations with painful temporomandibular disorders (TMD) and whether the interaction is multiplicative or additive. METHODS: In this case-control study, all participants (n = 705) were part of the multicenter Validation Project and were recruited as a convenience sample of community cases and controls and clinic cases. Logistic regression analyses were applied to test for the association between self-reported bruxism (sleep and/or awake) and the presence of painful TMD, and odds ratios (ORs) with 95% confidence intervals (95% CIs) were computed...

STATEMENT OF PROBLEM: Ceramic restorations are popular because of their excellent optical properties. However, failures are still a major concern, and dentists are confronted with the following question: is sleep bruxism (SB) associated with an increased frequency of ceramic restoration failures? PURPOSE: The purpose of this systematic review and meta-analysis was to assess whether the presence of SB is associated with increased ceramic restoration failure. MATERIAL AND METHODS: Observational studies and clinical trials that evaluated the short- and long-term survival rate of ceramic restorations in SB participants were selected...

INTRODUCTION: Temporomandibular disorder is an umbrella term for various clinical problems affecting the muscles of mastication, temporomandibular joint and associated structures. This disorder has a multifactor etiology, with oral parafunctional habits considered an important co-factor. Among such habits, sleep bruxism is considered a causal agent involved in the initiation and/or perpetuation of temporomandibular disorder. That condition can result in pain otologic symptoms. OBJECTIVE: The aim of the present study was to investigate the relationship between temporomandibular disorder and both otologic symptoms and bruxism...

Rhythmic masticatory muscle activity can be a normal variant of oromotor activity, which can be exaggerated in patients with sleep bruxism. However, few studies have tested the possibility in naturally sleeping animals to study the neurophysiological mechanisms of rhythmic masticatory muscle activity. This study aimed to investigate the similarity of cortical, cardiac and electromyographic manifestations of rhythmic masticatory muscle activity occurring during non-rapid eye movement sleep between guinea pigs and human subjects...

Bruxism is a sleep disorder characterized by grinding and biting teeth with multifactorial etiology, resulting in deleterious effects on teeth, periodontium, and temporomandibular joint. There is a lack of scientific evidence evaluating the effectiveness of medicines in treating this parafunction. The present case report was drafted under the rules of CARE checklist. An 8-year-old male patient with sleep bruxism and associated symptoms received a combined homeopathic therapy of Phytolacca decandra 12c and Melissa officinalis 12c for 2 months...

Although well studied since the 50's, bruxism remains a largely unknown pathology. Its origin is complex, mixing psychological as well as neurological, odontological and hypnic aspects. However, the few analyzes performed on this topic have allowed to set convincing etiopathological hypotheses, including central dysregulation of the dopaminergic system as well as of the neuro-masticatory system. To avoid harmful consequences as headaches, temporomandibular disorders and premature dental scuffs / fractures, it is mandatory to diagnose bruxism as early as possible...

BACKGROUND: An increasing number of studies have indicated that the central and autonomic nervous systems play roles in the genesis of sleep bruxism (SB). The role of specific neurochemicals in SB has been a subject of interest. OBJECTIVE: In this study, we use proton magnetic resonance spectroscopy ((1) H-MRS) to determine whether the levels of γ-aminobutyric acid (GABA) and glutamate (Glu) are different in the brainstem and bilateral cortical masticatory area (CMA) between possible sleep bruxism (SB) patients and controls, and discuss whether the brainstem or cortical networks which may affect the central masticatory pathways are under the genesis of SB...

The therapeutic applications of botulinum toxin (BoNT) have grown manifold since its initial approval in 1989 by the US Food and Drug Administration (FDA) for the treatment of strabismus, blepharospasm, and other facial spasms. Although it is the most potent biologic toxin known to man, long-term studies have established its safety in the treatment of a variety of neurologic and non-neurologic disorders. This review focuses on some novel and uncommon uses of BoNT in the treatment of movement disorders, such as oromandibular dystonia, including bruxism, anterocollis, camptocormia, tremor, tics, tardive and levodopa-induced dyskinesia, and restless legs syndrome...

BACKGROUND: Obstructive sleep apnea (OSA) is one of the common prevalent conditions present worldwide. The process of abnormal habits related to clenching and grinding of teeth is referred to as bruxism and is characterized under the heading of parafunctional activity of the masticatory system. Osseointegrated dental implants represent advancements in the field of odontology. Despite its high success rate, failure and complications are often associated with dental implant treatment due to a number of factors...

This case report describes the fabrication of 3 single crowns for a patient with weakened abutment teeth. The patient exhibited nocturnal bruxism and clenching but refused to use an occlusal appliance. The abutment teeth were endodontically treated and presented with loss of tooth structure and thin axial walls. The patient was seeking a metal-free restoration, and all-ceramic restorations were contraindicated because of the potential for abrasion of the opposing teeth and direct force transmission to the weak abutment teeth...
