“…18 Our findings could be attributed to the unique characteristics of removable appliances which apply intermittent forces and often have a bite-opening effect, which has been found to decrease muscle activity. 44 However, further research is required to fully investigate this phenomenon, as the effects are anticipated to subside after orthodontic treatment completion.…”

BackgroundThe association between orthodontic treatment and temporomandibular disorders (TMD) has been contentious in the literature.ObjectivesTo analyse the associations between orthodontic treatment and TMD diagnosis and diseases characteristics.MethodsThis case–control study included 291 individuals, 192 TMDs and 99 controls. All patients underwent assessment based on a questionnaire and a clinical examination according to Axis I of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Differences in orthodontic treatment between TMDs and controls, as well as across different TMD diagnoses within the TMD group were analysed. Patients who underwent orthodontic treatment were compared to those who did not, regarding their trauma history, bruxism, aggressive teeth brushing, level of oral hygiene, pain scores, muscle tenderness scores and subjective sleep quality.ResultsOf the 291 participants, 119 (40.9%) underwent orthodontic treatment and 172 (59.1%) had no orthodontics experience. Orthodontic treatment included: mandibular orthodontic treatment (102 subjects) and maxillary orthodontic treatment (113 subjects) of those 47 used a headgear.Following multivariate analysis among TMDs, orthodontic treatment was associated with a good level of oral hygiene versus poor (Odds ratio [OR]: 5.17 [1.04–25.59]), lower number of tender muscles [OR = 0.84 (0.74–0.96)] and lower (better) Pittsburgh Sleep Quality Index (PSQI) scores (OR = 0.86 [0.76–0.97]). None of the studied parameters maintained a statistically significant association with orthodontic treatment in the multivariate analysis among the entire study population.ConclusionsUtilising a holistic approach, this study supports the main hypothesis that orthodontic treatment is not associated with TMD diagnosis and disease characteristics.

“…The inclusion and exclusion criteria were previously described. 6 Briefly, all participants had a Class I occlusion, a positive overjet and an overbite of ,3 mm, skeletal normal bite, full permanent dentition without third molars, no edentulous areas, no significant facial deformity, no signs or symptoms of temporomandibular disorders, and no orthodontic treatment in the past 3 years.…”

“…At the second visit, bite-raising using light-cured orthodontic band cement was performed on the palatal cusps of the upper first molars, as described in a previous study. 6 Briefly, after polishing, rinsing, drying, and isolating the occlusal surfaces of the respective molars, Ultra Band-Lok BLUE (Reliance Orthodontic Products Inc, Itasca, Ill) was applied in a thermoplastic sheet template (3 3 5 3 2-mm width 3 length 3 height trapezoid slot) and placed on the isolated occlusal surfaces. A light-curing unit, providing a minimum of 600 mW of continuous output, was used to cure the material by positioning the tip adjacent to the occlusal surface of the molars for 30 seconds.…”

“…However, the effect on masticatory function and the potential impairment when using this method have not been determined. A previous study 6 revealed that superficial masseter and anterior temporalis electromyography (EMG) activity was reduced immediately during clenching and chewing after the application of this bite-raising method. It was subsequently hypothesized that masticatory function would be affected by this biteraising method.…”

Objectives: To evaluate the effects of bite-raising with light-cured orthodontic band cement, a method commonly used in contemporary orthodontic treatment, on masticatory function, as assessed by objective and subjective methods. Materials and Methods: The objective evaluation of masticatory performance and subjective evaluation of masticatory ability were performed on 30 healthy volunteers (19 females and 11 males, 22.3 6 1.56 years) with a normal occlusion. Assessment was performed before and immediately after bite-raising. The bite-raising was done by adding light-cured orthodontic band cement (3 3 5 3 2-mm width 3 length 3 height) on the palatal cusps of the upper first molars. The masticatory performance index (MPI) was calculated from chewed test food particles using a sieving method. For the subjective evaluation, the participants performed the food intake ability (FIA) test using a questionnaire with six types of food. The correlation between the evaluation methods was determined. Results: The MPI and FIA scores of the participants were significantly reduced after bite-raising (P , .001). The MPI and FIA score reduction was not significantly different between females and males. No significant correlations were found between the changes in MPI and FIA scores. Conclusions: Masticatory function after bite-raising with light-cured orthodontic band cement was immediately reduced, both objectively and subjectively. However, because there was no significant correlation between the objective and subjective results, an individual may not perceive his/her decreased masticatory ability to the same degree as masticatory performance was reduced. Further study is required to evaluate the long-term adaptation to this bite-raising method. (Angle Orthod. 2020;90:263-268.) a MPI indicate masticatory performance index; FIA, food intake ability; and CI, confidence interval. P-value from comparison between mean difference in females and males (independent t-test for MPI, Mann-Whitney U-test for total, hard food, and soft food FIA score).

“…With the loss of each tooth, the inter-occlusal distance decreases unevenly, which is further influenced by several factors, including age, the presence and location of the remaining teeth, and the presence of removable orthopedic structures in the patient's oral cavity [5]. Masticatory dysfunction occurs in all types of pathology of the masticatory system simultaneously with changes in structure [6]. The aesthetic aspect and the electrical excitability of the pulp are however violated, which ultimately creates downstream problems, including an increased risk of developing complications [7,8].…”

Funds collection zebranie funduszy SummaryBackground. Dysfunction of the masticatory muscle group occurs in all types of masticatory system pathology. This is sometimes associated with changes in the musculoskeletal system, which are manifested in hypertension and hypotonia of the masticatory group of muscles, that cause a decrease in occlusal height. Material and methods. There were 123 patients enrolled, aged 35-54 years, who were made temporary fixed, fiberglass-reinforced plastic prostheses for the upper or lower jaw. There are several methods to improve the quality of orthopedic treatment with fixed bridges with reduced occlusal height, considering the condition of the masticatory muscles. One is the use of temporary fixed structures that provide a gradual increase in occlusal height, allow muscles to adapt to new conditions, and promote restructuring of "usual" myostatic reflexes. Results. To examine the effect of fixed structures on the m. masseter and m. temporalis, a technology for the manufacture of advanced temporary bridges was developed. This allowed us to study the process of masticatory muscle group adaptation to fixed orthopedic structures kept on the abutment teeth of patients without fractures for 6 months. In addition, it was possible to prepare the dental and maxillofacial system for permanent orthopedic treatment. Conclusions. Determination of the average total values of m. masseter and m. temporalis allowed us to establish the most effective intervention for patients with reduced occlusion height before, 1 month, and 6 months after temporary orthopedic treatment. There was a tendency for patients of all groups to approach the absolute symmetry.
