Purpose: The aim of the paper is to present the methodology of computer aided designingand manufacturing of an all-ceramic multi-unit bridge restoring missing teeth and the lostsoft and hard tissues of the oral cavity as a result of surgical treatment of oral tumor.Design/methodology/approach: The methodology of computer aided designing andmanufacturing of the multi-unit all-ceramic bridge was presented on the basis of an actualclinical case of a patient who underwent the surgical treatment of myxoma of the oral cavity.All the steps of clinical and technical production of the bridge were described and illustrated.Findings: It is possible to use the CAD/CAM technology to design and manufactureall-ceramic multi-unit bridges restoring missing teeth and the lost soft and hard tissues ofthe oral cavity. The design of the bridge must be clinically validated using mock-ups and onlythen can be implemented for the CAM software.Practical implications: Thanks to the method of designing and manufacturing of multiunitall-ceramic bridges for patients with significant lost of the soft and hard tissues of themouth it is possible to carry out a prosthetic rehabilitation of patients after trauma and tumorsurgery.Originality/value: : The execution of extensive bridges with the maximum available heightof about 25 mm requires a high technological rigor at the design and manufacture stage. Toensure longevity of the reconstruction, it is necessary to plan all the work while maintainingthe maximum thickness of the substructure. It is desirable to provide minimum of 2 mmthick substructure and the surface of at least 20 mm2 or more in the cross-sections. At thesame time, the structure of the bridge must be supported on the alveolar ridge to provideaesthetics and endurance. |
