Introduction: Toothlessness is a condition caused by the age-related and genetic changes
or damage. Tooth replacement is a process that must restore the function and the aesthetics.
Dentures and fixed replacements cause a lot of inconvenience for some patients, so they
often opt for the implant care. The surveys indicate that the patients with the dental implants
are more satisfied and confident. Purpose: The purpose of this thesis is to provide a
theoretical overview of the zirconia ceramic reinforced bridge construction on four implants
and the importance of the development of modern technology in terms of function, accuracy
and aesthetics. The aim of the theoretical work is to review the positive and negative features
of the digital fabrication method and the characteristics of the materials used. Methods: A
descriptive method of data search was used, using online databases such as PubMed, Science
Direct and Cobiss. In the dental laboratory, we digitally fabricated a screwed construction.
Results: An impression (impregum material) was obtained from the dentist's office, from
which the plaster model was cast and scanned. The teeth were placed and the occlusal tissues
were modelled in CAD software. We continued with the milling in CAM. Discussion and
conclusion: Implant supported jaw replacement is a successful procedure for restoring a
edentulous jaw. It achieves functional and aesthetic standards for the patient. The bridge
structure is screwed into the jawbone. This method has also a positive hygienic aspect.
