Introduction: In patients, regardless of age, there is often a loss or excessive wear of dental tissue, which is later replaced by prosthetic replacements. Initially the remaining dental structure is protected by provisional or. temporary dental replacements. These help to restore normal speech and chewing function for up to 2 years, and they ensure a normal appearance. The development of modern technologies and advances in the development of modern materials enable various ways of a rapid temporary care of teeth. Purpose: The purpose of this diploma work is to review the literature of modern additive and subtractive technologies and materials suitable for the manufacture of provisionals. Based on this the purpose is to identify and compare the differences and similarities in the method of manufacture, time, colour, aesthetics and durability of individual provisionals made with DLP technology and milling technology and to make a prosthetic product. Methods: In the introductory part, a descriptive method with a review of mainly foreign literature on the topic of the diploma work was used. In the practical part, the upper and lower temporary bridges were made in the laboratory under the supervision of a mentor by using the additive method (DLP) and the subtractive method (milling). Results: In the result part the properties of made provisionals were compared. The emphasis was placed on the method and the time of making the temporary bridges. The colour, aesthetics and the properties of the materials used were also compared. Discussion and conclusion: We have found out that the need for provisionals is quite high. There are various ways of making the provisionals. With the progress of modern technologies and the appearance of different modern materials, provisionals will be made faster and they will be of better quality. Currently, they meet satisfactory aesthetic standards, regardless the method of manufacture. In the future their sealing function and tensile strength might be improved, and they might gain in durability.
