Uvod: Zobni vsadki so v takšni ali drugačni obliki obstajali že v starih civilizacijah. Eden izmed najbolj uporabljenih materialov za zobne implantate je titan. Material ima številne koristne lastnosti, ki pa jih dodatno izboljšamo s površinskimi modifikacijami. Subtraktivne tehnike površinskih modifikacij razdelimo na mehanske, kemične in fizikalne. Vsaka izmed teh pa ima svoje načine obdelave, ki na svoj način doprinesejo k izboljšanju materiala. Okvirno mehanska uporabi fizično silo, kemična se poslužuje raztopin in fizikalna uporabi različne vrste energije za potek modifikacij. Namen: Namen diplomskega dela je predstaviti vrste površinskih modifikacij titana in njegovih zlitin. Diplomsko delo vsebuje tudi kratko zgodovino implantatov. Za razumevanje potreb po modifikacijah so predstavljene lastnosti titana in njegove zlitine ter pojmi, ki so pomembni pri uspešnih vsadkih. Izbrane mehanske, kemične in fizikalne metode bodo predstavljene, opisano bo, kako se izvedejo in kako doprinesejo k izboljšanju titana in njegovih zlitin. Predvsem je cilj predstaviti metode, ki obstajajo. Metode dela: Za pridobitev informacij smo uporabili deskriptivno metodo dela. Pregledali smo članke, knjige in strokovno literaturo na teme titan, površinske modifikacije titana in vsadki. Iskali smo po številni bazah podatkov, kot so Google Učenjak, Pubmed, Web of science, Science Direct. V sklopu končnega izdelka smo v laboratoriju izdelali spodnjo in zgornjo protezo na implantatih za pacienta. Rezultati: V laboratoriju smo prilagodili zgornjo protezo na konusih in izdelali novo spodnjo protezo na dveh lokatorjih. Razprava in zaključek: Modifikacije so nujno potrebne metode preoblikovanja površin titana, da ga lahko uporabljamo v zobni implantologiji. Z izboljšanjem lastnosti povečajo uspešnost integracije vsadka v telo. Metode so številne, niso pa vse primerne za uporabo na zobnih vsadkih. Z dodanimi raziskavami in študijami lahko izboljšamo obstoječe in odkrijemo nove metode površinskih modifikacij titana in njegovih zlitin.

Abstract

Introduction: Dental implants have existed in one form or another since ancient civilisations. One of the most widely used materials for dental implants is titanium. The material has many beneficial properties, which are further enhanced by surface modifications. Subtractive surface modification techniques are divided into mechanical, chemical and physical. Each of these has its own treatment methods, which contribute in their own way to the improvement of the material. Broadly, mechanical uses physical force, chemical uses solutions and physical uses different types of energy to carry out the modifications. Purpose: The purpose of this thesis is to present the types of surface modification of titanium and its alloys. The assignment also includes a brief history of implants. To understand the need for modifications, the properties of titanium and its alloys are presented and the concepts that are important for successful implants are discussed. Selected mechanical, chemical and physical methods will be presented, describing how they are performed and how they contribute to the improvement of titanium and its alloys. In particular, the aim is to present the methods that exist. Methods: We reviewed articles, books and scientific literature on titanium, surface modifications of titanium and implants. We searched a number of databases such as Google Scholar, Pubmed, Web of science, Science Direct. As part of the final product, we made a lower and upper implant-supported prosthesis for a patient. Results: In a lab we adjusted an existing upper denture on implants and made a new lower denture on two locators. Discussion and Conclusion: Modifications are essential techniques for transforming the surface of titanium to make it suitable for use in dental implantology. By improving its properties, they enhance the success of implant integration in the body. There are numerous methods available, but not all are suitable for use on dental implants. Through additional research and studies, we can improve existing methods and discover new surface modification techniques for titanium and its alloys.
