ABSTRACT

Aim of the study The metal-ceramic fixed restorations is a reliable method of rehabilitation of the dental arch, offering effective morphological and functional aspects, which ensures resistance, biocompatibility with dental tissues and aesthetic harmony in a unitary work, as ceramics have the ability to imitate the appearance of natural teeth. Materials and methods Our study aimed to highlight the particularities of performing mixed restorations, with an aesthetic ceramic component system, applied on metallic infrastructure, in the lateral area of the mandibular dental arch. The workflow presented elements specific to each stage, by combining the classic steps of the algorithm with digital technologies for the design and development of infrastructures, and then the application of ceramic mass systems and sintering stages. Results The use of digital technologies both in the clinic, for the scanning stage, and in the laboratory – ExoCAD software, for the design of the metal infrastructure, in combination with analogue techniques for the application and sintering of ceramic masses for the aesthetic component, led to obtaining the optimal parameters of mixed metal-ceramic restorations. Conclusions Laboratory CAD/CAM systems involve a more extensive technological process, often utilizing advanced materials, typically employed for complex cases requiring high precision and durability, such as full-arch restorations or fixed prosthesis.
