Introduction. The application of flexible occlusal splints in therapy of the stomatognatic system is recommended for short-term use only because of the risk of muscle overloading or occlusal plane disorders. Mouthguards used in prevention of head and mouth injuries are a modification of occlusal splints. They are made of flexible material with properties enabling absorption of impact energy. Due to regular use during trainings and competitions they may have an impact on the incidence of stomatognatic system ailments. Aim of the study. To assess the factors determining the choice of a mouthguard type and its influence on the stomatognatic system. Material and methods. A survey was conducted among 1279 mouthguard users to collect demographic data and information concerning mouthguards on the occurrence of problems arising from their use including pain in the area of the stomatognatic system. Statistical analysis of the results was also performed. Results. 36% athletes with standard mouthguards, 37% with “boil and bite” and 44% with custom-made ones have a tendency towards strong clenching of dental arches. Participants using a custom-made mouthguard reported chewing muscle fatigue more often than the users of the standard and “boil and bite” type, but they did not report any pain located in the area of temporomandibular joint. People experiencing fatigue and with a strong clenching of dental arches tendency significantly more often choose a type considering its retention ability, whereas pain in the temporomandibular joint area does not influence their preferences. Athletes, who declare teeth clenching, more frequently indicate the retention factor as important. Conclusion. It is necessary to conduct further research on the use of mouthguards considering their impact on the stomatognatic system.

Abstract Objectives The purpose of this study was to evaluate the short-term effect of active skeletonized sutural distractor (ASSD) appliance on temporomandibular joint morphology of class III malocclusion subjects. Materials and Methods This was a prospective interventional study. Cone-beam computerized tomography (CBCT) images of 22 patients were taken before and after treatment by using Planmeca Promax 3D CBCT machine version 2.9.2 (Planmeca OY Helsinki, Finland). The condylar width, height, length, roof of glenoid fossa thickness, and all joint spaces were measured. The condylar position was determined based on Pullinger and Hollander formula. The condylar shape was determined as per Kinzinger et al. The condylar volume was calculated by using Mimics software (Materialize, Belgium). Statistical Analysis Data analysis was performed by using SPSS software version 24. Wilcoxon paired signed-rank test was used to compare the difference in temporomandibular joint morphology and condylar volume between pre- and post-treatment measurements. Chi-square test was used to compare the condylar position and shape. Results The superior (p = 0.000 on the right side, p = 0.005 on the left side) and posterior joint spaces (p = 0.000 on both sides) were decreased after the treatment, respectively. The condyles were rotated upward and backward, thereby increasing the anterior joint spaces (p = 0.000 on both sides) after the treatment. The condylar volume increases after treatment, but no significant differences were observed (p = 0.903 on the right side, p = 0.062 on the left side). Conclusion The significant changes were observed in joint spaces. The condyles were more anteriorly placed before treatment. Condylar position and shape alter in response to ASSD treatment. The condylar volume did not show any significant change.

Extended postoperative mandibular reconstructions due to orofacial disease involving the temporomandibular joint (TMJ) in immature patients remain a challenge as a result of ongoing growth, which is usually affected by the disease and treatment. Current reconstructive techniques based fully on alloplastic total joint replacement fail to meet fully the anatomical and functional requirements for the masticatory system and speech development. Fourteen children aged 12.6 ± 2.6 with tumors or congenital deformities affecting the mandible and TMJ were included in the study. Radical surgical treatment according to our own protocol was performed through microvascular anastomotic flap reconstruction of the soft tissues and bones, together with total TMJ custom replacements. Follow-up lasted 2–6 years. During the follow-up, increases in the mandible body (13% growth) and ramus (12% growth) were observed, both of which were related (p < 0.001). This is the first report concerning the immediate reconstruction of the mandible with ramus and total TMJ in children and adolescents that combines a free vascularized graft and total individual prosthesis of the TMJ. The presented technique enabled optimal function of the TMJ, growth of the mandible, and further rehabilitation of the patients. The technique was demonstrated to be safe, reliable, and provide good functional and cosmetic outcomes.

Introduction: Cognitive and physical impairments are common in cardiac arrest survivors. Global measures including the Modified Rankin Scale (mRS), Cerebral Performance Category (CPC) and the 10-domain CPC-Extended (CPC-E) tend to improve over 1 year. The CPC-E is scored from 1-5 with higher scores signifying greater impairment. However, with the CPC-E, individual functional domains (alertness, logical thinking, attention, motor skills, short-term memory, basic and complex activities of daily living (ADL), mood, fatigue, and return to work) may recover at different rates. Hypothesis: We hypothesized that patients would have recovery in all domains of the CPC-E at 1 year after index cardiac arrest. Methods: A prospective cohort study of cardiac arrest survivors was conducted between 2/1/16 and 5/31/17. Chart review was done for baseline demographic data. Outcome measures including mRS, CPC, and CPC-E scores were assessed at discharge, 3 months, 6 months, and 1 year. We defined recovery of a CPC-E domain when >90% of patients had scores of 1-2 in that domain. Results: Of 71 subjects, 35 completed the CPC-E at discharge, 35 at 3 months, 25 at 6 months and 31 at 1 year. The most common reasons for exclusion were patient declined or were lost to follow up. The majority (N=37; 52%) were female, with a mean (SD) age of 58(17) years. Most arrests occurred out of hospital (N= 49; 69%), 27 (38%) had a shockable rhythm and the majority (N=37; 54%) were discharged home. CPC-E domains of alertness (N=35, 100%) logical thinking (N=35; 100%), and attention (N=33; 94%) recovered by hospital discharge. BADLs were recovered by 3 months (N=33; 94%). The majority of patients (N=24;77%) experienced slight-to-no disability or symptoms (mRS 0-2 / CPC 1-2) at 1 year follow up. CPC-E short term memory (67%), motor (87%), mood (87%), fatigue (13%), complex ADL (74%), and return to work (55%) did not recover fully by 1 year. Conclusions: In survivors of cardiac arrest, CPC-E domains of alertness, logical thinking, and attention recover rapidly, while domains of short term memory, motor, mood, fatigue, complex ADL and ability to return to work are chronically impaired 1 year after arrest. Interventions to improve recovery in these domains are needed.

Abstract Introduction Pectus carinatum (PC) is a congenital chest wall deformity which is characterized by the protrusion of the sternum and costal cartilages. Although orthotic and exercise therapies are commonly offered by physicians for PC treatment, there is a lack of evidence on the benefits of exercises and how long the orthosis should be worn. The aim of this study is to investigate the effects and feasibility of custom-made compression orthosis and exercises in the treatment of PC. Materials and Methods Patients with PC aged 7 to 17 years old were randomized into three groups: compression orthosis 23 hours, compression orthosis 8 hours, and control group. All groups received exercises for 1 hour a day for 3 weeks. Additionally, compression orthosis 23 hours group wore the orthosis for 23 hours a day, while compression orthosis 8 hours group wore the orthosis for 8 hours a day. PC protrusion, pressure of correction, thorax lateral and anteroposterior parameters, external chest wall measurements, and Nuss Questionnaire were evaluated before and after the treatment. Also, adverse effects, retention, and compliance were assessed. Feasibility was evaluated by calculating the percentages of recruitment, retention, and safety. Results The compression orthosis 23 hours group showed greater improvements than the other groups. After treatment, all groups showed significant changes in protrusion, pressure of correction, and external chest wall measurements. Adverse events occurred with similar frequency across groups. Retention percentages did not differ among groups. Conclusion Compression orthosis use for 23 hours can be recommended rather than its use for 8 hours because 23 hours of orthosis use has better correction and similar adverse effects.
