Abstract

Uvod: Pasivni snemni ortodontski aparati so kljub razvoju fiksnih tehnik in vedno večji uporabi nevidnih opornic še naprej pomemben del sodobne ortodontske prakse. Njihova uporaba je še posebej razširjena pri pacientih v obdobju rasti in razvoja, kjer omogočajo vzdrževanje doseženih rezultatov, po aktivnem ortodontskem zdravljenju, preprečevanje ponovitve nepravilnosti ter usmerjanje rasti čeljusti brez aktivne uporabe mehanskih sil. Prednost teh aparatov je v enostavni uporabi, cenovni dostopnosti, olajšanemu vzdrževanju ustne higiene in možnosti individualne prilagoditve, zaradi česar so še vedno klinično nepogrešljivi pri zdravljenju zobnih in čeljustnih nepravilnosti. Namen: Namen diplomskega dela je bil podrobneje predstaviti vlogo pasivnih snemnih aparatov v zobni in čeljustni ortopediji, opisati njihove konstrukcijske značilnosti, delovanje ter klinično uporabo pri različnih oblikah zobnih in čeljustnih nepravilnosti. Poseben poudarek je bil namenjen bionatorju tipa II, ki se uporablja pri zdravljenju nepravilnosti razreda II (distalni griz), in prikazu njegove izdelave v laboratoriju. Metode dela: Uporabljena je bila deskriptivna metoda, ki je vključevala pregled strokovne literature v slovenskem in angleškem jeziku. Vire smo iskali v bazah PubMed, Science Direct, Google Scholar in COBISS, pri čemer smo vključili tudi nekatere starejše članke, pomembne za zgodovinski in strokovni kontekst. Poleg tega smo v zobnem laboratoriju Stomatološke klinike UKC Ljubljana izdelali bionator tipa II, pri čemer so bile posamezne faze postopka natančno dokumentirane s fotografijami. Rezultati: V nalogi je podrobno opisan postopek izdelave bionatorja tipa II, individualno prilagojenega pacientu z nepravilnostjo razreda II. Rezultati potrjujejo, da aparat omogoča usmerjanje rasti spodnje čeljustnice, pripomore k vzdrževanju pravilnega griza in dolgoročno stabilizira rezultate ortodontske terapije. Razprava in zaključek: V razpravi je poudarjena klinična vloga pasivnih snemnih aparatov pri dolgoročni stabilizaciji griza in vplivu na rast in razvoj čeljustnic. Primerjava med različnimi funkcionalnimi aparati je pokazala, da ima vsak aparat specifične mehanizme delovanja, medtem ko bionator dodatno vpliva na mišično ravnovesje, kar povečuje trajnost rezultatov. Sklepamo lahko, da pasivni snemni aparati, predvsem bionator tipa II, ostajajo pomembno orodje v ortodontiji, saj s prilagodljivostjo in učinkovitostjo dopolnjujejo sodobne terapevtske pristope.

Secondary title: Passive removable appliances and their use in orthodontics
Secondary abstract: Introduction: Passive removable orthodontic appliances, despite the progress of fixed techniques and the growing popularity of invisible aligners, remain an essential part of modern orthodontic practice. Their use is particularly common in growing patients, where they maintain achieved treatment results, prevent relapse, and guide jaw development without the application of active mechanical forces. The main advantages of these appliances include ease of use, affordability, maintenance of oral hygiene, and the possibility of individual adaptation, which makes them clinically relevant in the treatment of dental and skeletal malocclusions.Purpose: The aim of this thesis was to present the role of passive removable appliances in orthodontics, to describe their constructional characteristics, mechanisms of action, and clinical applications in different types of dental and jaw irregularities. Special attention was given to the type II bionator, commonly applied in the treatment of class II irregularity and to the demonstration of its fabrication under laboratory conditions.Methods: A descriptive method was applied, combining a comprehensive review of scientific literature in Slovene and English with practical laboratory work. Sources were obtained from PubMed, Science Direct, Google Scholar, and COBISS, and some older publications were also included for historical and professional context. In addition, a type II Bionator was fabricated in the dental laboratory of the University Medical Centre Ljubljana, with each fabrication stage carefully documented through photographs and integrated into the presentation. Results: The thesis describes the complete fabrication process of a type II Bionator, individually tailored for a patient with class II irregularity. The results confirm that the appliance effectively supports growth of lowe jaw, contributes to bite stabilization, and plays an important role in maintaining the outcomes of orthodontic therapy.Discussion and conclusion: In the discussion, the clinical role of passive removable appliances in the long-term stabilization of the bite and their influence on jaw growth and development is emphasized. A comparison among different functional appliances has shown that each device has specific mechanisms of action, while the bionator additionally affects muscular balance, thereby increasing the durability of results. It can be concluded that passive removable appliances, especially the Bionator type II, remain an important tool in orthodontics, as their adaptability and effectiveness complement modern therapeutic approaches.
