[Duration of splint therapy in patients with temporomandibular joint disorders]. / Prodolzhitel'nost' splint-terapii u patsientov s sindromom bolevoi disfunktsii visochno-nizhnechelyustnogo sustava.

AIM: Studying the duration of treatment in patients with temporomandibular joint pain dysfunction syndrome, and the relationship of the duration of treatment with the age of the patient at the beginning of therapy. MATERIALS AND METHODS: The study was carried out using information from medical records of dental patients, information from additional examinations of patients who were treated at the National Medical Research Centre for Dentistry and Maxillofacial Surgery of the Ministry of Health of Russia from 2016 to 2022. Statistical research methods: to evaluate the normality of the distribution, graphical methods were used, as well as the Shapiro-Wilk criterion. RESULTS: The duration of splint therapy in patients with temporomandibular joint pain dysfunction syndrome varied from 4 to 27 months. The average duration of treatment of patients using occlusive splints was 10.5±5.3 months. Without abnormal observations, the average duration of splint therapy in patients with TMJ pain syndrome was 9.6±4.1 months. The obtained data allow stating the absence of a correlation between the age of patients and the duration of splint-therapy. CONCLUSION: The majority of patients (68.4%) complete the splint therapy stage within 1 year, and a very small part (1.8%) are treated for more than 1.5 years. The duration of treatment of patients with temporomandibular joint pain dysfunction syndrome does not depend on age or gender.

The main guidelines for innovative prosthetic technologies and effective methods for replacing defects in hard tissues of teeth and dentitions in patients with pathological abrasion of teeth, secondary deformations of dentitions and generalized periodontitis are implemented in the department of modern prosthetics technologies through the introduction of digital technologies (3D modeling, scanning, printing), development of new methods and techniques of treatment, study of the features of reparative regeneration in the field of dentition defects and changes in the prosthetic bed, analysis of morphological changes in traumatic occlusion, integration with other clinical departments of the institute.

[The use of magnetic sensory system for mandibular movement patterns recording in patients after TMJ reconstruction]. / Ispol'zovanie magnitno-sensornoi sistemy dlya registratsii patternov dvizheniya nizhnei chelyusti u patsientov, perenesshikh rekonstruktsiyu visochno-nizhnechelyustnogo sustava.

OBJECTIVE: The aim of this study was to record mandibular kinematics in patients after total TMJ endoprosthesis using a magnetic sensory system. MATERIAL AND METHODS: The movement of the mandibular was examined in 10 patients who underwent TMJ reconstruction using total endoprostheses. The condylar range of motion, the angle of the transversal condylar inclination (TCI), the speed of joint movement (max S) and the stability distance between the position at the beginning of movement and at the end (Start/end) of TMJ prostheses and native joints were measured 1 week before surgery (T0) and 12 months after (T1). RESULTS: The study showed an increase in the linear distance of the native joint when opening (p=0.004), protrusion (p=0.004), balancing side (p=0.001) and max S of the native joint and endoprosthesis when opening (p=0.009), working side (p=0.008) and balancing side (p=0.001). A decrease in indicators was observed in the Start/end of the native joint when opening (p=0.035), protrusion (p=0.02), working side (p=0.004), as well as the endoprosthesis relative to the pathological joint when opening (p=0.028), protrusion (p=0.001) and balancing side (p=0.003). CONCLUSION: In the present study, in all cases, a slight but clearly defined translational shift on the side of the intervention was detected on the control condylograms, which can be referred to as «pseudotranslation¼.

[Cephalometric findings in patients with TMJ anterior disk displacement without reduction]. / Tsefalometricheskie kharakteristiki patsientov s perednim nevpravliaemym smeshcheniem sustavnogo diska visochno-nizhnecheliustnogo sustava.

Objective of the study was to determine representative cephalometric signs for the patients with TMJ anterior disk displacement without reduction (ADWoR). Twenty one female patients with ADWoR, which was confirmed by MRI, were included in the study. Cephalometric parameters described by Arnett-McLaughlin and Jarabak were measured by means of lateral cephalograms and computed tomograms (CT) to determine the growth pattern of the facial skeleton. All the data obtained was evaluated statistically. The investigation has revealed reduction in vertical measurements of facial skeleton and several signs of hyperdivergent growth pattern in the sample.

[Calculation of mean angle values of sagittal and transversal joint tracks basing upon the data of electron axiography and their possible clinical value].

Calculation of mean angle values of sagittal and transversal joint tracks basing upon the data of electron axiography was done with the help of KADIAKS compact system ("Gamma Dental", Austria) in 58 patients. It was determined that sagittal joint tracks for articulator systems with direct trajectory were on the right side 50.17±11.02° for 3 mm, 49.09±10.43° for 5 mm and 43.09±9.10° for 10 mm, on the left side - 54.84±10.09° for 3 mm, 53.95±9.52° for 5 mm and 49.31±8.62° for 10 mm; for the articulator Reference SL with curved trajectory were on the right side 44.38±11.40° for 3 mm, 45.76±10.61° for 5 mm and 45.39±8.92° for 10 mm, on the left side - 49.16±10.64° for 3 mm, 50.45±9.74° for 5 mm and 51.77±8.68° for 10 mm. Transversal joint tracks for the articulator Reference SL were on the right side 6.96±6.51° for 3 mm, 7.50±5.88° for 5 mm and 7.22±5.08° for 10 mm. Considerable values of standard deviations and irregular distribution of signs in the limits of studied statistical pooled data made doubtful possible clinical use of mean angle values of sagittal and transversal joint tracks.

[Experience with utilization of the Michigan splint for temporary splinting during osteogingivoplasty]. / Opyt ispol'zovaniia michiganskoi shiny dlia vremennogo shinirovaniia pri provedenii osteogingivoplastiki.

The experience of use Michigan splint for temporary splinting of the maxillary tooth at realization of flap surgery at 23 patients. Stages of clinical and laboratory procedures making the splint are described and analysed. Is appeared, that the reduction of mobility of teeth in the period following surgical intervention occurs on the average within 0.5-1 month faster, than with the patients after similar interventions, but without splinting. At the same time it is proved obvious, that the usage Michigan splint promotes normalization of functioning of muscles activity masticatory system and TMJ and helps in revealing of occlusal interferences.

Basing on the results of global electromyography performed for 51 patients with parkinsonism, it is concluded that volley muscular activity may be related with neurophysiological segmentary reflexes: discharge of alpha-motoneurons from primary endings of the muscle spindle; autogenic, reciprocal and feedback inhibition of alpha-motoneurons.
