Uvod: Brezzobost je danes vse pogostejši pojav, s katerim se sooča sodobno zobozdravstvo. S pomočjo delnih zobnih protez nadomeščamo delno brezzobost, pacientu pa omogočimo samostojno vstavljanje, snemanje in čiščenje zobnih nadomestkov. Cilj snemnoprotetične oskrbe je vzpostavitev funkcije in videza, s čimer ohranimo preostala tkiva v ustni votlini. Danes izdelava kovinskih baz s pomočjo CAD/CAM tehnologije nadomešča klasično ulite kovinske baze. Stereolitografija (SLA) je dodajalna tehnologija, s pomočjo katere 3D tiskamo načrtovane objekte in jih pozneje tudi ulivamo. Selektivno lasersko taljenje (SLM) je dodajalna tehnologija, pri kateri se material v obliki prahu vari v plasteh, kar zagotavlja visoko natančnost. Za uspešno poslovanje podjetja in njegov obstoj je potrebno natančno postavljati cene. Kadar seštejemo vse stroške, ki jih povzroči izdelava izdelka ali storitev imenujemo lastna cena. Stroški, ki jo sestavljajo zajemajo stroške materiala, storitev, amortizacije dela, nabave, uprave in prodaje. Namen: Predstavitev tehnologije selektivnega laserskega taljenja (SLM) in stereolitografije (SLA). Med rezultati diplomskega dela smo, s pomočjo tehnologij SLA in SLM, predstavili izdelavo dveh kovinskih baz, izračunali lastno ceno izdelka ter ugotavljali, katera izmed opisanih tehnologij je za laboratorijskega zobnega protetika cenovno najugodnejša. Metode dela: Uvodni teoretični del je napisan po pregledu strokovne literature. Pri iskanju člankov smo si pomagali s strokovnimi bazami Google Schoolar, PubMed, Science Direct in Research Gate. Rezultati: V zobnem laboratoriju smo izdelali kovinsko bazo s pomočjo tehnologije SLA, iz rezkalnega centra pa prejeli izdelano kovinsko bazo s pomočjo tehnologije SLM. Razprava in zaključek: Lastni ceni kovinskih baz, izdelanih s pomočjo tehnologij SLA in SLM, se razlikujeta za 15 evrov. Največja razlika med njima se vidi v ogromnem časovnem prihranku, v primeru izdelave kovinske baze s pomočjo tehnologije SLM. Časovni prihranek, ki smo ga namerili, znaša 122 minut, kar laboratorijskemu zobnemu protetiku omogoča, da se, medtem ko v rezkalnem centru poteka izdelava kovinske baze, posveti izdelavi ostalih zobnih nadomestkov.

Introduction: edentulousness is today an increasingly common phenomenon faced by modern dentistry and is treated by replacing teeth with partial dentures. With the help of partial dentures we can successfully treat partial endentulousness. The goal of removable partial dentures is to restore function and appearance, thereby preserving remaining tissues in the oral cavity. Metal base scan can be produced with the help of CAD/CAM technology. Stereolitograpy (SLA) is an additive technology with the help of which we 3D- print planned objects and later cast them. Selective laser melting (SLM) is an additive technology in which powdered material is sintered in layers, ensuring high precision. For the successful operation of the company, it is necessary for the company to set prices accurately to ensure existence. The cost price of the product is the sum of all costs caused by the product or service. The basic components of cost price are costs of materials, services, labor, indirect production, production costs, administration and sales costs. Purpose: purpose of this thesis is to present the technology of selective laser melting (SLM) and stereolitography (SLA). In the practical part of this thesis, we made two metal bases, made with the help of SLA and SLM technology and calculated the cost price of both of the products and determine which one is more affordable for dental laboratory. Methods: the theoretical part is written after a review of Slovenian and foreign literature. We used Google Scholar, PubMed, Science Direct, Research Gate to help us search for literature. Results: We made metal base in dental laboratory using SLA technology, and recieved another metal base, made by SLM technology from the milling center. Discussion and conclusion: the cost price of both metal bases, made by SLA and SLM technology differs for 15€, but the major difference is in the massive time savings if the metal base is made by SLM technology. Time saving in our case was measured for 122 minutes. The time saving allows the laboratory dental technician to focus on production of other dental replacements while the metal base is being manufactured in the milling center.
