“…The tooth clenching and unilateral mastication in subjects wearing old dentures cause noises in the TMJ and leave the mastication muscles more sensitive 6 . With the exchange of old dentures for new satisfactory dentures, re‐establishment of equilibrium occurs (occlusal and OVD), 5,10 and the tooth clenching habit disappears and produces a reduction in joint vibrations and masticatory muscle sensitivity.…”

“…Most studies have found no correlation between signs and symptoms of TMDs and factors relating to overall quality of the dentures and the occlusal status of the dentures; 2,3 however, some studies found that occlusal instability was a potential factor contributing to the development of TMD among complete denture wearers 1 . Incorrect vertical dimension and centric relation were the most frequent causes of TMD among complete denture wearers; 4–6 however, others did not find that discrepancies in vertical dimension of existing complete dentures affected the severity of TMD 2,5,7–10 …”

“…Statistical analysis revealed no significant differences between TMD and healthy subjects relating to the number and intensity of contacts. These findings agree with previous results (Droukas et al ., 1985; Ingervall et al ., 1991; Takenoshita et al ., 1991), but are at variance with others (Gianniri et al ., 1991; Wanman & Agerberg, 1991; Yamashita et al ., 1991; Henrikson et al ., 1997; Fujii, 1999). Unfortunately, the present and the above quoted investigations cannot be compared completely.…”

“…(1991) and Wanman and Agerberg (1991) examined adolescents, Henrikson et al . (1997) also studied adolescents and further involved subjects with class II malocclusion, and Fujii (1999) included in the non‐healthy group patients with only eminence clicking. It should be once more emphasized that differences in study design and methods of data collection can lead to opposite results.…”

The aim of this study was to describe the distribution of occlusal contacts in subjects with signs or symptoms of temporomandibular disorder (TMD), and to assess whether any difference exists with healthy subjects. Twenty-five university dental students with complete natural dentition who exhibited TMD (13 females and 12 males, age from 19 to 30 years) and 25 age- and sex-matched controls entered the study. Occlusal contacts were evaluated in the intercuspal position and wax registrations were made in all subjects. Occlusal contacts were classified according to location and intensity. No differences were found between TMD and control groups for the overall number and distribution of contacts or for any side and intensity of contact. An intra-subject analysis showed that TMD subjects had significantly greater bilateral asymmetry in the number of contacts than controls. Median absolute difference of the number of contacts on right and left sides was 3 (95% CI, 2-4) in TMD subjects and 2 (95% CI, 1-2) in controls. In TMD subjects with mono-lateral TMD there was a significant concordance (88.9%) between the side of disorder and the side of higher number of contacts. These findings, while confirming that a significant relationship exists between distribution of occlusal contacts and TMD, further suggest that in young adults it may be primarily expressed by asymmetries in occlusal contact patterns. Existence and aetiology of any association of TMD with occlusal contacts should be further investigated.

“…Splints were fabricated from self-curing clear acrylic, with a cuspid guide to create a rise in protrusive and lateral movements. Splints were adjusted with the participants in the horizontal position in order to provide habitual closure and stable occlusion in the retruded contact position (RCP) 13. Participants were asked to use the splint continuously, even while asleep.…”

Computerized analysis of occlusal contacts in bruxism patients treated with occlusal splint therapy

et al. 2013

PURPOSEOcclusal splints are commonly used to prevent tooth wear caused by bruxism. However, the effects of splints on occlusion are still unclear. Although it is rarely alluded in literature, splints can provoke severe occlusal alterations and other complications. This study was aimed to identify differences in the responses of individuals with bruxism and healthy individuals to a full-arch maxillary stabilization splint in terms of occlusal changes.MATERIALS AND METHODSOcclusal contacts in 20 (5 male, 15 female) bruxism patients and 20 (5 male, 15 female) controls with normal occlusion were evaluated before and after occlusal splint therapy. T-Scan III, a computerized occlusal analysis system, was used to simultaneously measure occlusion and disclusion times as well as left-right and anterior-posterior contact distributions before splint therapy and 3 months after therapy. Wilcoxon and Mann-Whitney U tests were used for statistical analyses (α=.05).RESULTSNo differences were found in the posterior contact of bruxism patients before and after stabilization splint treatment. However, differences in posterior contact were observed between bruxists and normal individuals prior to treatment, and this difference disappeared following treatment.CONCLUSIONThe results of this study showed the use of a stabilization splint may not have an effect on occlusion. However, the area of posterior occlusal contact among bruxists was found to be greater than that of normal individuals. According to this study, the clinical use of splints may be harmless.
