Uporaba polietereterketona v zobozdravstvu s primerom izdelave delne proteze : diplomsko delo

Šorli, Gregor (author), Rojko, Franc (mentor), Bohinc, Peter (reviewer)

Uvod: Pri starajočem se prebivalstvu se zelo pogosto srečujemo z brezzobostjo. Fiksnoprotetično zdravljenje pa kljub številnim prednostim ni vedno najustreznejša rešitev in potrebna je oskrba z snemnoprotetičnim nadomestkom. Ta mora biti izdelan tako, da ustrezno zadovolji potrebe pacienta in mu izboljša kakovost življenja. V zobozdravstvu se že vrsto let dogajajo številne spremembe pri načinu izdelave zobnoprotetičnih pripomočkov. Uporabljajo se številne tehnologije in materiali. PEEK je polimerni nekovinski material, ki se s svojimi lastnostmi kosa s konvencionalnim materialom. Uporablja se v fiksni in snemni protetiki, pa tudi v ortodontiji. V snemni protetiki se lahko uporablja za izdelavo številnih konstrukcij, kot so ogrodja delnih protez, parodontalno in implantno podprte teleskopske prevleke in gredi, ojačitve akrilatnih delnih in totalnih protez ter obturatorji. Namen: Namen diplomskega dela je na podlagi literature raziskati in predstaviti material PEEK in izdelavo delne proteze s subtraktivno metodo ter postopek izdelave opisati. Opredeliti želimo primernost uporabe materiala PEEK za izdelavo delne proteze s subtraktivno metodo. Metode dela: V teoretičnem delu diplomskega dela smo uporabili deskriptivno metodo na podlagi pregleda strokovnih člankov iz strokovnih baz, predvsem v tujem jeziku. Uporabili smo bazi Google Scholar in PubMed. V praktičnem delu smo po informacijah iz literature izdelali ogrodje delne proteze iz materiala PEEK ter predstavili postopek oblikovanja in izdelave izdelka s rezkanjem. Rezultati: Digitalne oblike modelov smo natisnili in s programsko opremo digitalno načrtovali ter oblikovali ogrodje delne proteze. To smo s subtraktivno tehniko rezkanja pretvorili v fizično obliko. Uporabili smo disk materiala PEEK. Sledila sta še obdelava in poliranje. Naleganje izdelka je bilo po pričakovanjih dobro. Razprava in zaključek: Potrebe po izdelavi snemnoprotetičnih nadomestkov so zaradi različnih dejavnikov še vedno velike. Pomembno je, da se lahko za izdelavo nadomestkov uporabljajo različni materiali in tehnologije, ki omogočajo oskrbo pacientov z različnimi potrebami. Za ogrodja delnih protez se še vedno najpogosteje uporablja kovinski material, a ta v določenih primerih ni ustrezna rešitev. Primeren pa je lahko PEEK, ki s svojimi lastnostmi glede na potrebe pacienta predstavlja ustrezno alternativo.

• Title: Use of polyetheretherketone in dentistry and an example of partial denture design process : diploma work

Abstract

Introduction: As our population ages, we are often faced with edentulose. Despite the many advantages offered by fixed prosthetic care, it is not always the most appropriate solution. Therefore care with a removable prosthetic is needed. It must be designed in a way that adequately meets the patient's needs and improves quality of life. The dental field has seen many changes in the way prosthetics are manufactured over the years. PEEK is a polymeric non-metallic material whose properties rival those of conventional materials. It is used in fixed and removable prosthetics as well as in orthodontics. In removable prosthetics, it can be used for fabrication of a wide range of constructions such as partial denture frameworks, periodontally and implant-supported telescopic crawns and shafts, acrylate partial and total denture reinforcements and obturators. Purpose: The aim of this thesis is to investigate and present the PEEK material and the fabrication of partial dentures using the subtractive method and to present the fabrication process itself. We wish to determine the suitability of PEEK material for partial dentures manufactured with subtractive method. Methods: In the theoretical part of the thesis, we used the descriptive method using literature from professional articles from professional databases, mainly in a foreign language. The databases used were Google Scholar and PubMed. In the practical part a partial denture frame made of PEEK material was designed. We also presented product design and manufacturing. Results: We printed models and used software to digitally design and create the partial denture framework. This was converted into a physical form using a subtractive milling technique. We used a PEEK material disc. After that followed postprocessing and polishing. As expected, the product achieved good results. Discussion and conclusion: The need for fabrication of removable prosthetic restorations remains high due to various factors. It is important that different materials and technologies can be used to fabricate restorations to care for patients with different needs. Metal is still the most widely used material for partial denture frameworks, but it is not an appropriate solution in certain cases. This can be resolved by using PEEK, which has the properties to provide an appropriate alternative based on patients needs.
