Introduction: Physical and chemical agents in the work environment are the main causes of occupational diseases, they can also cause non-occupational diseases and have a significant impact on worker productivity. The work of a laboratory dental prosthetics is meticulous and creative, it requires manual dexterity, a sense of responsibility and concentration, therefore, it is important to have a workplace that considers the work environment and physical factors: thermal environment, lighting, noise, and vibrations.The wide range of materials used in dentistry today have harmful effects when ingested or inhaled, both locally and systemically with immediate or delayed effects. Chemical risk factors for laboratory dental prosthetics include metals from dental alloys free particles of crystalline silica. Purpose: The purpose of this diploma thesis is to present the risk factors in the working environment that affect laboratory workers. Methods of work: The theoretical part of the thesis summarises the literature in Slovene and English languages in the field of laboratory dental prosthetics and the current Slovenian legislation. Results: We have produced a metal-porcelain coating and a metal-porcelain bridge. The framework was made using the according to modern digital technology; with computer-aided design, computer-aided manufacturing and selective laser melting. Discussion and conclusion: With digital technology, we have avoided some harmful processes in the manufacture of our product. Where harmful risks could not be avoided, we have taken precautions to protect ourselves at work.
