Evaluation of articular disc loading in the temporomandibular joints after prosthetic and pharmacological treatment in model studies.

Background: Temporomandibular joint dysfunction is often related to excessive load in the stomatognathic system.

Objectives: The objective of the model tests, using numeric calculations, was to assess the articular disc loads in the temporomandibular joints after prosthetic and pharmacological treatment of functional disorders of the masticatory organ.

Material And Methods: The study involved 10 patients, aged 21-48 years, of both sexes, randomly selected from a group of 120 patients treated with relaxation occlusal splints (60 patients, group I) and intramuscular injection of botulinum toxin type A (60 patients, group II), suffering from temporomandibular joint dysfunction with the dominant muscle component.

The evaluation of the accuracy of shape imaging of prosthetic abutment.

Purpose: The aim of the study was the in vitro evaluation of the accuracy of shape imaging of abutment teeth using different impression compounds.

Methods: To compare the accuracy of the shape of the numerically imaged real prosthetic abutments with the tested models of abutments obtained with the replica technique, the Geomagic Qualify program was applied. Making use of the licensed program Statistica, statistical analysis of the results obtained was conducted.

Evaluation of the saliva cortisol levels in patients under prosthetic treatment due to functional disorders of the masticatory organ.

One of the main etiological factors of the stomatognathic system dysfunction is stress and psychoemotional disorders. During stressful situations, there is an increase in the level of cortisol, the so-called stress hormone. Literature data indicate the existence of a correlation between blood cortisol levels and its amount in the saliva.

Controversies on the position of the mandibular foramen - review of the literature.

Foramen of mandible is the most important point considering the Halsted anesthesia. Position of this foramen seems to be stable, however there are lots of controversies regarded to its position. Based on the current literature authors revised datas from literature considering the location of the mandibular foramen.

Auriculo-vestibular symptoms related to structural and functional disorders of stomatognatic system.

Auriculo-vestibular symptoms are otolaryngological complaints which frequently co-occur with functional disorders of masticatory organ. These symptoms include: earache, plugged ears sensation, sudden hearing impairment, burning pain of the throat, tinnitus, and dizziness. The aim of the study was assessment of co-occurrence of functional disorders of masticatory organ and auriculo-vestibular symptoms, in patients referred for otolaryngological treatment.

Experimental research on the possibilities of maintaining thermal conditions within the limits of the physiological conditions during intraoral preparation of dental implants.

The objective of the study was to evaluate the degree of temperature change in the bone, directly adjacent to the implant site during the abutment part of one-piece implants, during procedures involving different cutting techniques. Three different one-piece implants: Osteoplant, Nobel Direct, Q-implant were cut with air-turbine burs after insertion in fresh pig ribs. Tests were performed with a variety of cooling techniques including air and air-liquid coolant.

Measurement of occlusal forces in the therapy of functional disorders with the use of botulinum toxin type A.

Functional disorders of the stomatognathic system include dysfunctions leading to pathological increase of the occlusal forces generated by mandibular adductors. High values of these forces are the cause of numerous disorders within the masticatory organ such as pathological abrasion of the teeth, tension headaches and pain in the region of the temporomandibular joints. The aim of this study was assessment of occlusal forces in the course of the therapy of painful types of functional disorders with the use of botulinum toxin type A - the drug causing muscle relaxation.

Application of a diagnostic-therapeutic procedure using implant-supported dental prosthesis as a preventive therapy for candidiasis of upper gastrointestinal tract in complete denture users.

Our previous studies demonstrated that the use of acrylic based prosthesis in edentulous patients had a direct impact on the increased incidence of oral mycosis and further episodes of mycosis in the digestive tract. This dependency is associated with formation of a space between the surface of the prostheses and adhering mucosal membrane, where a specific micro environment is being formed, which - as stated - creates a superior breeding ground mainly for microorganisms of the genus Candida.

Melatonin and its role in oxidative stress related diseases of oral cavity.

The role of the oral cavity in the pathogenesis of diseases of various systems such as the gastro-intestinal tract (GIT), cardiovascular and immune systems has been recently evaluated. While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this review focuses on the involvement of melatonin (MT) in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of MT in dental disorders, especially in periodontal inflammation.

[Vertical pathological attrition--causes, consequences and treatment methods].

The mechanism of development of vertical pathological attrition leading to destruction of the palatine and vestibular surfaces of the anterior teeth is described. Vertical pathological attrition is most frequent in acquired occlusal defects after loss of abutement zones, and in certain congenital malocclusions (supraocclusion). This condition may lead to damage to the whole stomatognathic system.

[Teeth placement in complete denture by the Calotte method in Cracow modification].

Theoretical principles and the modification of the calotte method of teeth placement in complete prosthesis are presented. The method combines the elements of the articulation and static theories, but is easy for teaching and introduction, is not requiring a change of the clinical management (in relation to the generally accepted principles) or use of special devices of articulators which are presently unavailable. Checking of correct teeth placement is also easy.

[The Cracow modification of the Calotte method of teeth placement in clinical evaluation].

The purpose of the paper was checking of theoretical principles and assessment of the clinical usefulness of the calotte method of teeth placement in Cracow modification. In 110 patients this study was carried out according to the following schema: prosthetic treatment using complete prostheses with teeth placed by the modified method or by the Gysi-Fischer method, for comparison, and periodically repeated clinical examinations considering such elements as: articulation and occlusion, fixation and statics of prostheses, masticatory function and speech, and aesthetic result and adaptation process. In all these parameters good results were obtained by the modified method.

[Review of the presently accepted theories of teeth positioning in complete prostheses].

The review paper describing the presently used principles of the theory of teeth positioning in complete prostheses. The author indicates their advantages and disadvantages, and the possibility of their application in general prosthetic practice.

[Criteria of anatomo-physiological evaluation of the conditions of the prosthetic substrate and a review of the classification of edentulous mouth].

The criteria for the assessment of the conditions of the mouth for the needs of prosthetic treatment are presented and the classifications of edentulous mouth used as yet are surveyed.

[Results of toothlessness treatment by calottic method in the Cracow modification. Clinical studies].

The purpose of the paper was to control the new method of teeth positioning in complete dentures based on the modification of callottic method in clinical practice. Clinical studies depended on occlusion and articulation estimation, examination of denture statics, control of occlusion height and registration of the patients' subjective experiences. They concerned 81 toothless patients divided into 2 groups according to the specific classification and wearing complete dentures in which the teeth had been positioned according to the modified method and Gysi-Fischer' method.
