“…This system could observe not only the surface loss but also the warp deformation of the splint by scanning the splint made of a specific elastic material on the cast. 37 In the current study, Geomagic Control X and Geomagic Studio was used to calculate the depth and volume losses for both kinds of splints. This method was first described by Mehl et al 38 and has been proven to be an appropriate way of assessing clinical wear.…”

“…For occlusal splints, Kentaro proposed an evaluation system which can analyse the location and direction of wear facets and surface loss. This system could observe not only the surface loss but also the warp deformation of the splint by scanning the splint made of a specific elastic material on the cast 37 . In the current study, Geomagic Control X and Geomagic Studio was used to calculate the depth and volume losses for both kinds of splints.…”

Sleep bruxism (SB) is defined previously as a kind of repetitive jaw-muscle activity mainly manifested by grinding, clenching, and/or bracing or thrusting of the mandible during sleep. 1 Although the aetiology of bruxism is not exactly clear, many studies regarded it as multiple causes including morphological, psychosocial, genetic and other possible factors. 2-5 Long-term SB can lead to tooth wear, jaw-muscle pain and occlusal trauma, and in some severe forms can cause difficulty with speech or swallowing. 6 With the deepening of research in recent years, some studies have constantly discussed and updated the definition of SB. 7-9 Therefore, it tends to be regarded as a risk factor rather than a kind of disease. In 2018, Lobbezoo et al stated in a new study that SB should be regarded as a 'behaviour' among

“…Scratching in the friction direction is an evidence of abrasion wear of polymers [56]. Observations, terminology and definitions contained in the papers [32,55,56], as well as others, incl. [57], are the most appropriate in relation to scratch damage of polymers used to orthodontic appliances.…”

“…Researchers found that deformation and abrasion were observed where human teeth contacted polymeric orthodontic appliances. It was shown that the degree of damage to orthodonic appliances was correlated with maximum muscle activity during sleep [32]. Such damage limits the effect of treatment and the durability of medical devices.…”

The paper presents the studies and results of the Shore hardness and scratch test of polymer materials used in medical devices. Polymers of organic PMMA (poly(methyl methacrylate)) origin for the manufacture of orthodontic appliances were tested. Samples of test materials differed in manufacturing technology. The surface functional properties of four materials were compared. Hardness tests were performed with the Shore D hardness test method. The scratch test was done with a Rockwell diamond cone indenter. The hardness was also calculated from the scratch test. Shore's highest hardness was demonstrated in 1A material. But the differences in Shore's hardness were small. Larger differences between the tested materials were shown in the scratch test than in the Shore hardness test. The lowest residual scratch depth (Rd) was obtained for 1A material. 3A material had the highest scratch hardness.

“…One of the main challenges of dentistry is to identify whether the patient presents bruxism in the daytime or nighttime according to his report of myofascial pain [ 4 ]. Sleep bruxism is a common chronic condition in approximately 8% of the population [ 7 ] and, if improperly diagnosed or untreated, it can cause considerable damage to the teeth; the repair is complex [ 8 ]. According to a recent review, both types of bruxism, both physiological and pathological, have associated causal factors that are yet unknown.…”

Background:Bruxism is defined as a repetitive activity of grinding the teeth through lateral or protrusive movements of the mandible, and it is considered the most complex and destructive functional disorder. In addition, erosion caused by diet or reflux can damage the remaining teeth.Objective:In this report, a patient with bruxism and dental erosion was treated with a multidisciplinary approach to restore the function and aesthetic.Methods:This clinical report describes the management of an adult woman, 33 years old, who was dissatisfied with the aesthetics of her smile and complained of joint pain and headaches. As result of her condition, the patient’s dentition exhibited generalized wear on the vestibular and incisal surface of the upper incisors incompatible with her age, moderate darkening of the teeth and excess gingival tissue in the upper incisors. After a detailed anamnesis and clinical examination, a diagnosis of bruxism and acid erosion caused by a diet rich in citrus foods and beverages was obtained. Forthwith, a treatment plan was established, and the patient underwent home bleaching, gingivoplasty and ceramic laminates of lithium disilicate on the anterior teeth. After the rehabilitation was completed, a night guard was made to reduce the symptoms of bruxism and avoid fracture of the ceramic restorations. The patient was followed at different time intervals.Conclusion:The improvement in the aesthetics of the teeth was significant and remained stable after periodic controls in which no adverse effects were observed.
