The analysis of innovative manufacturing method of complete removable dentures

Abstract

BACKGROUND: The optimization of the digital protocol in the manufacture of complete removable dentures to obtain milled dentures with design close to those modeled using computer-aided design and computer-aided manufacturing software is an urgent problem in dental prosthetics.

AIM: To analyze the manufacturing of complete removable dentures and demonstrate the results of in vitro studies of prostheses obtained according to the developed protocol using the Kravets verticulator and prostheses in which the bases are bonded to the teeth with resins of cold and hot polymerization.

MATERIALS AND METHODS: With digital technologies, using the proposed modernized Wieland Digital Denture (Ivoclar Vivadent) protocol, 10 bases and 10 corresponding dentitions were obtained by milling, according to pre-made templates obtained using 3D printing. Then, five samples were bonded with cold cure resin using the verticulator, and five samples were made with hot cure resin and verticulator.

RESULTS: On most of the tooth treated with hot cure resin, the interlayer between the structures of the base and dentition was not observed, or interlayers had a thickness of 80±4 microns. The thickness of the interlayer of the cold curing specimens was 273±25 microns. Pores are not observed for plastic bonded specimens, both cold and hot cured.

CONCLUSION: The proposed method allows the use of digital technologies to obtain a monolithic plastic prosthesis, which eliminates inaccuracies in tooth positioning, during placement in the base of the prosthesis, and bind the base of the prosthesis and teeth using hot-curing acrylic plastic.
