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.

Objective. The purpose of this case report is to present a digital mandibular tracing technique used to evaluate a patient with temporomandibular joint dysfunction (TMD). Clinical features. A 65-year-old Caucasian female patient presented with chronical jaw pain in her temporomandibular joint (TMJ) area. The patient describes a dental history of orthodontic and prosthodontic treatment. Orally patient exhibits super erupted teeth, multiply fractured restorations, facial gingival recession, and rotated teeth. The patient also had an uneven occlusal plane and non-working side contact at maxillary first and mandibular second molars. Evaluation and outcome. A digital mandibular tracing technique, cone beam computed tomography, and full-arch optical impressions were used to evaluate the patient's condition. The left condyle was slightly flat compared to the right one on the anterior surface. Limited protrusion and lateral movements and asymmetric border movements were detected. Apparently, an incomplete orthodontic treatment at the patient's early age, iatrogenic mandibular anterior restorations, and hit and slight effect are considered as causes for Temporo-mandibular joint problems. The recommended treatment plan sequence for this patient is an occlusal adjustment, replacement of defective restorations and fabrication of an occlusal guard for one of the arches. Conclusion. Digital mandibular tracing system can help the dentist to diagnose and analyze the causes of TMD patient specifically and individually. It also provides quick resolution and management for patients with TMD.

Abstract Background The incisal guidance angle (IGA) is related to temporomandibular joint (TMJ), and changes to the IGA are often involved in the prosthetic and orthodontic treatment of anterior teeth. However, the influence of incisal guidance on the growth, development and remodelling of the TMJ is not yet clear. The aim of this study was to investigate age-related morphological differences in the TMJ in subjects with different IGAs. Methods Cone-beam computed tomography (CBCT) images of 274 patients were included (group 1, IGA < 45°; group 2, 45° ≤ IGA ≤ 60°; group 3, IGA > 60°). Each group was then divided into 4 age groups (group a, 6–12 years; group b, 13–16 years; group c, 17–25 years; group d, 26–33 years). TMJ morphology was assessed by linear measurements, angular measurements, and subjective evaluations. The IGA and occlusal plane angle were also measured. Results Anterior inclination of condyle (AIC) increased with age in the three IGA groups but decreased from 17 years onward in group 2 (P < 0.05). In the age groups analysis, the AIC in group 1 was smaller than that in group 3 but larger than that in group 2 (P > 0.05). Articular eminence inclination (AEI) decreased with age in group 1 (P = 0.027) but increased with age in group 3 (P = 0.053). The AEI in group 2 was larger than that in group 1 at 17–25 years (P = 0.046), and it was larger in group 3 than in group 1 at 26–33 years (P = 0.047). The IGA had a weak correlation with AEI (P < 0.05). Conclusion The articular fossa of patients with shallower incisal guidance changed to a flatter shape with age, whereas the condylar anterior slope and articular eminence of patients with steeper incisal guidance changed towards a steeper alignment. There was a correlation between IGA and TMJ shape.

Relevance. Temporomandibular joint dysfunction is one of the most widely spread and common disease nowadays. It includes disorders on different levels of whole body and multi symptom as clinical manifestation. There is still less of evidence in ethiopathology of Temporomandibular dysfunction(TMD).Objective. The research aimed to find new etiological factors impacting the formation of TMJ, recorded growth and developmental disorders of the facial skull in the experimental group. Materials and methods. The sample group consisted of 59 patients. The experimental group included 38 patients with lateral joint displacement; the control group included 21 patients. Subjects were examined with functional probes, occlusion diagnosis with articulation paper Baush 200,100,8 microns, cephalometryc analysis by Grummons, computed tomography of temporomandibular joint, licensed software application Planmeca Romexis Viewer, statistical analyses with program IBM SPSS Statistic Base v.22.Results. 91.6% of patients with dentofacial deformities of the maxilla (ddm) also have TMJ with lateral displacement of the articular heads of the mandible. Patients without maxillary dentofacial deformities experience lateral displacement of the articular heads with a frequency of 8.7% and probable risk of 10.5 (95% CI 2.79-39.8). Patients in 1group (63,16%) experiences asymmetric inclination of the angles of the right and left upper jaw and occlusal plane around tooth number 6 and 7, 79.94% of patients in the experimental group recorded a displacement of the mandible <89 ° dental deformity. There is a specifically, ramifications of the pathological factors via rotational, simultaneous, one-sided, and three-level move with a delay in the horizontal growth of the dental apparatus.
