Vpliv cervikalnega dela prevleke na parodoncij : diplomsko delo

Požgaj, Martina (author), Marion, Ljubo (mentor), Rojko, Franc (comentor)

Uvod: Zaradi sodobnih tehnologij fiksnoprotetične oskrbe in keramik se naginjamo k fiksnoprotetični oskrbi, s katero najučinkoviteje dosežemo naraven videz zoba. Za dosego dolgotrajne fiksne oskrbe pa moramo poskrbeti za cervikalni del prevleke in njen vpliv na parodoncij. Namen: Namen diplomskega dela je prikazati različne možne odnose, oblike in lege cervikalnega dela prevleke do parodoncija, izpostaviti prednosti in slabosti različnih cervikalnih stopnic ter kateri dejavniki vplivajo na uspešnost fiksnoprotetične oskrbe v odvisnosti cervikalnega dela prevleke do parodoncija. Metode: Metode dela vključujejo pregled domače in tuje strokovne literature ter izdelavo praktičnega izdelka v zobnem laboratoriju. Rezultati: V diplomskem delu smo opisali in predstavili vse dejavnike, ki so povezani s cervikalno stopnico in njenim vplivom na parodoncij, ki vplivajo na uspešnost fiksnoprotetičnega sidra. Izdelali smo klasično kovinsko-porcelansko prevleko na zobeh 14 in 26, kovinsko-porcelansko prevleko z digitalno tehnologijo CAD/CAM rezkanje CrCo ogrodja na zobu 14 ter kovinsko-porcelansko prevleko z digitalno tehnologijo CAD/CAM selektivnega laserskega taljenja ogrodja na zobu 26. Polno-keramične prevleke smo naredili iz stabiliziranega cirkonijevega oksida (YTZP) po tehniki CAD/CAM in po tehnologiji stiskanja in barvanja polno-keramične prevleke, oboje na zobu 21. Postopki izdelave so opisani in slikovno dokumentirani. Razprava in sklep: S sodobnimi tehnologijami so cervikalne zapore bolj natančne, z razvojem dentalne keramike pa vzajemno dosegajao visoko estetiko in videz naravnega zoba. Polno-keramične prevleke zaradi uspešnosti, estetike in mehanskih lastnosti počasi nadomeščajo kovinsko-porcelanske prevleke. Kovinsko-porcelanske kot polno-keramične prevleke lahko indiciramo tako nad kot pod robom proste dlesne, dokler prevleka ne poškoduje ali iritira biološke širine. Kovinsko-porcelanske prevleke zaradi slabše estetike odsvetujemo v vidnem področju, medtem ko pri polno-keramičnih prevlekah ni ovir.

• Title: The impact of the fixed prosthodontics crown edge on the parodontal tissues : diploma work

Abstract

Introduction: Due to modern technologies of fixed prosthetics and ceramics, we tend to fixed prosthodontics, with which we can achieve the natural look of the tooth most efficiently. In order to achieve long-term fixed care, we must take care of the cervical part of the coating and its effect on parodontium. Purpose: The purpose of the diploma work is to show various possible relationships, shapes and positions of the cervical part of the coating to parodontium, highlight the advantages and disadvantages of various cervical stairs and which factors influence the performance of fixed prosthodontic care in dependence of the cervical part of the coating to the parodontium. Methods: Work methods include a review of domestic and foreign professional literature and the production of a practical product in a dental laboratory. Results: In the diploma work, we described and presented all the factors that are related to the cervical step and its effect on parodontics, which influence the performance of the fixed prosthetic anchor. We produced a classic metal-ceramic coating on teeth 14 and 26, metal-ceramic coating with digital technology CAD / CAM milling CrCo frame on tooth 14 and metal-ceramic coating with digital CAD / CAM technology selective laser melting of the frame on the tooth 26. Full-ceramic coatings were made from stabilized zirconium oxide (YTZP) according to the CAD / CAM technique and by the pressing and painting technology of the full-ceramic coating, both on the tooth 21. The manufacturing processes are described and documented. Discussion and conclusion: With modern technologies, the cervical barriers are more precise, and with the development of dental ceramics, it interacts with high esthetics and the appearance of a natural tooth. Full-ceramic coatings are slowly replacing metal-ceramic coatings due to their performance, esthetics and mechanical properties. As metal-ceramic as full-ceramic coatings can be indicated both above and below the margin of the free gum until the coating damages or irritates the biological width. Metal-ceramic coatings due to poorer esthetics are not recommended in the visible field, while there are no obstacles in the case of full-ceramic coatings.
