“…Čimić i wsp. 12 wykazali, że średnie nachylenie drogi stawowej w odniesieniu do płaszczyzny frankfurckiej miało wartość ok. 60°. W innym badaniu tego autora, kąty te dla w pełni uzębionych pacjentów wyniosły 40°±27° względem płaszczyzny Campera co stanowi 55°±27° względem frankfurckiej.…”

Streszczenie Wstęp. Prace protetyczne powinny być dopasowane do okluzji i artykulacji zwarciowej pacjenta. Do leczenia stosowane są tradycyjne i nowoczesne systemy artykulacyjne, które pozwalają odtworzyć indywidualne ruchy żuchwy. Cel pracy. Celem pracy było porównanie wartości kątów nachylenia drogi stawowej oraz kątów Bennetta uzyskanych w badaniu ARCUSdigma II i na podstawie rejestratów zwarcia w artykulatorze Protar 7. Metoda. Badanie przeprowadzono na grupie 20 osób w wieku 23-30 lat z pełnym uzębieniem i prawidłową okluzją. U każdego pacjenta zarejestrowano położenie szczęki łukiem twarzowym AR-CUSevo. Przeprowadzono badanie urządzeniem ARCUSdigma II. Wykonano wyciski szczęki i żuchwy, odlano modele oraz oprawiono je w artykulatorze Protar 7. Pobrano rejestraty zwarcia w pozycjach maksymalnego zaguzkowania, protruzyjnej i laterotruzyjnych. Na ich podstawie w artykulatorze ustalono kąty stawowe. Porównano kąty nachylenia drogi stawowej i Bennetta z pomiaru elektronicznego i ustawienia w artykulatorze. Wyniki. Średnie wartości kąta nachylenia drogi stawowej względem płaszczyzny frankfurckiej Porównanie wartości kątów stawowych uzyskanych na podstawie badania ARCUSdigma II i rejestratów zwarcia w artykulatorze Protar 7 Zakład Protetyki Stomatologicznej, Uniwersytet Medyczny w Łodzi Kierownik: prof. dr hab. n. med. Beata Dejak Summary Introduction. Prosthetic restorations should be adjusted to the patients' occlusion and articulation. Traditional and modern articulator and face-bow systems that simulate individual jaw movements are used in the treatment.Aim of the study. The aim of the study was to compare the values of TMJ angles based on the ARCUSdigma examination and wax occlusion records in the Protar 7 articulator.Method. The study was conducted on a group of 20 patients aged 23-30 years with full dentition and normal occlusion. The position of the maxilla was recorded with face-bow ARCUSevo. Every patient was examined using ARCUSdigma II device. Cast models of the maxilla and mandible were made and mounted in Protar 7 articulator. Wax occlusion records were taken in intercuspal, protrusive and laterotrusive positions. On their basis TMJ angles were established in the articulator. The sagittal condylar inclination and Bennett angles relative to the Frankfurt plane obtained using electronic measurement and manual settings in the articulator were compared.Results. Mean values of sagittal condylar inclination angles based on occlusion records in Protar 7 articulator amounted to 56.9° on the left HASŁA INDEKSOWE: kąty nachylenia drogi stawowej, kąty Bennetta, Arcus Digma, Protar 7

“…Research into the effect of occlusal splint treatment in subjects with bruxism has shown its impact on changes in masticatory muscle activity, the incidence of bruxism, and quality of life. The results of research have shown a change in the range of mandibular movements in subjects with bruxism, however, no studies have been conducted so far regarding the changes in the value of mandibular movements in subjects with bruxism during and after the occlusal splint treatment ( 11 - 13 ). The condyle position in the temporomandibular joint has often been investigated, but as shown by Obrez and Gallo ( 13 ), only through the development of modern kinematic three-dimensional systems with six degrees of freedom it is possible to measure the condyle position and movement mathematically accurately.…”

“…The condyle position in the temporomandibular joint has often been investigated, but as shown by Obrez and Gallo ( 13 ), only through the development of modern kinematic three-dimensional systems with six degrees of freedom it is possible to measure the condyle position and movement mathematically accurately. So far, the research in which such devices were used has confirmed that occlusal splint impacts the condyle position in a way that vertical displacement of the condyle between maximum intercuspation (MI) and centric relation (CR) is increased, while the horizontal and transversal condylar displacement show considerable variability ( 11 , 12 ). The objective of this pilot study was to examine the impact of the occlusal splint treatment on mandibular border movements and the condyle position in subjects with bruxism.…”

Objective The objective of this pilot study was to examine the impact of occlusal splint treatment on mandibular border movements and the condyle position in subjects with bruxism. Materials and methods The study included 9 subjects diagnosed with bruxism (mean age 28.7) and 9 subjects in the control group (mean age 30.5). All subjects were adults, eugnathic, and with a dentoalveolar Angle Class I, without prosthetic restorations, previous or current orthodontic treatments, a systemic disease or previous surgical interventions in the temporomandibular joint. All experimental and control group subjects were provided with a standardized relaxation occlusal splint, which they wore for 8 weeks. During this time, an initial and three additional measurements of incisal opening (IO), left condyle opening (OLC), right condyle opening (ORC), left laterotrusion (LLI) and right laterotrusion (LRI) (after 2, 4 and 8 weeks) were performed using an Arcus Digamma II (Kavo) ultrasound device for mandibular movements recording. Using the same instrument, the condylar position during protrusion, left and right laterotrusion, and in the centric relation position (CR) was analyzed initially and after 8 weeks using the maximum intercuspation as reference point. Continuous variables were described using basic statistical parameters, and the statistical significance of differences between the variables was checked by the t-test and χ2 test (p <0.05). Results The values of IO, OLC, ORC, LLI and LRI increased after 8 weeks of wearing, with the highest increase for OLC, by 13.8%. No statistically significant difference (p <0.05) was found for any changes in movements. Changes in the condyle position during all movements and those in the CR were higher in the experimental group for 10 out of 14 measured parameters compared to the control group. A statistically significant difference was established for 5 out of 14 measured parameters after the occlusal splint treatment. Conclusions The results of this pilot study have proven the influence of the occlusal splint treatment on mandibular border movements in subjects with bruxism by increasing the range of movements. Also the changes of the condyle position in subjects with bruxism were greater compared to those in healthy subjects.
