Primerjava klasične in z globokim vlekom izdelane michiganske okluzijske opornice : diplomsko delo

Oblak, Petra (author), Rener-Sitar, Ksenija (mentor)

Uvod: Z michigansko okluzijsko opornico najpogosteje zdravimo paciente z bruksizmom in/ali s temporomandibularno motnjo. Z opornico zobe zaščitimo, da si med škrtanjem in stiskanjem zob zaradi bruksizma ne obrabljajo zobne ploskve in da se zmanjša obremenitev v čeljustnih sklepih. Namen: Namen diplomskega dela je izdelati in predstaviti tri različne načine izdelave michiganske okluzijske opornice: iz toplo polimerizirajočega akrilata, iz hladno polimerizirajočega akrilata in iz poliamidne folije s tehniko globokega vleka. Metode dela: Najprej smo pregledali tujo in slovensko strokovno literaturo s področja okluzijskih opornic za bruksizem in temporomandibularne motnje. Nato smo pri vseh treh načinih izdelave opornice natančno beležili čas izdelave in količine vseh porabljenih materialov. Vse tri opornice so bile izdelane za pacienta, ki ima diagnozo spalni bruksizem. Vsako od opornic je imel vstavljeno v usta 14 zaporednih noči med spanjem. Na podlagi vprašalnika OHIP za samooceno oralnega zdravja je po 14 dneh nošenja vsake opornice pacient ocenil stanje svojega oralnega zdravja. Ves čas nošenja vsake od treh opornic ni vedel, kako je bila posamezna opornica izdelana. Rezultati: Opisno in slikovno so natančno predstavljene laboratorijske faze izdelave treh različnih michiganskih okluzijskih opornic. Najkrajši čas izdelave je potreben za opornico, izdelano iz poliamidne folije s tehniko globokega vleka (93 min). Cena materiala za izdelavo opornice je najnižja za izdelavo opornice iz toplo polimerizirajočega akrilata (7,95 €). Ob upoštevanju časa izdelave in cene vseh uporabljenih materialov je najcenejša laboratorijska izvedba za opornico, izdelano s tehniko globokega vleka (26,38 €). Pacient je prav tako najbolje ocenil svoje počutje po nošenju michiganske okluzijske opornice iz poliamidne folije, narejene s tehniko globokega vleka. Kakovost življenja v zvezi z oralnim zdravjem je bila prav tako najboljša po nošenju opornice, izdelane s tehniko globokega vleka in najslabša po nošenju opornice iz toplo polimerizirajočega akrilata. Sklep: Opornica, ki je izdelava s tehniko globokega vleka, je v primerjavi z opornico iz toplega ali iz hladnega akrilata najcenejša in tudi pacient je ocenil svoje oralno zdravje najbolje po nošenju opornice, narejene s tehniko globokega vleka.

Abstract

Introduction: We mostly use a Michigan-style occlusal splint to treat patients with bruxism and/or temporomandibular disorders. The splint helps to protect teeth from grinding and clenching, prevents tooth wear due to bruxism and reduces strain to the jaw joints. Purpose: The purpose of this thesis was to present three different methods of manufacturing a Michigan occlusal splint using heat-cured acrylic, cold-cured acrylic, and thermoformed polyamide foil. Methods: Firstly, we reviewed foreign and Slovenian specialized literature about occlusal splints for bruxism and temporomandibular disorders. Then, we accurately recorded the manufacturing time and the quantity of all materials used. We made all three splints for a patient diagnosed with sleep bruxism. They wore each of the splints for 14 consecutive nights while sleeping. Based on the OHIP questionnaire for self-assessment of oral health, the patient assessed his health after each 14-day period. Throughout the study, the patient was not aware of the manufacturing methods used. Results: The laboratory process of manufacturing the three different occlusal splints is descriptively and graphically presented in the thesis. The splint made with thermoformed polyamide foil had the shortest manufacturing time (93 min). The cost of materials was the lowest for the splint made from heat-cured acrylic (EUR 7.95). Taking into account the processing time and the cost of all materials used, the lab version of the thermoformed occlusal splint was the most cost-effective solution (EUR 26.38). Furthermore, the patient evaluated his oral health as best after wearing the thermoformed splint. The patient also evaluated his quality of life related to oral health best after wearing the thermoformed. The heat-cured acrylic splint received the most negative evaluation. Conclusions: The splint made of thermoformed polyamide foil was the most cost-effective solution compared to the splints made from heat-cured acrylic or cold-cured acrylic. Moreover, the splint made of thermoformed polyamide foil was also the most positively evaluated by the patient.
