Fixed dental prostheses with vertical tooth preparations without finish lines: A report of two patients. J Prosthet Dent. 2016 May;115(5):520-6. doi: 10.1016/j.prosdent.2015.11.0110022-391310.1016/j.prosdent.2015.11.011https://hdl.handle.net/20.500.14352/115980Tooth abutments can be prepared to receive fixed dental prostheses with different types of finish lines. The literature reports different complications arising from tooth preparation techniques, including gingival recession. Vertical preparation without a finish line is a technique whereby the abutments are prepared by introducing a diamond rotary instrument into the sulcus to eliminate the cementoenamel junction and to create a new prosthetic cementoenamel junction determined by the prosthetic margin. This article describes 2 patients whose dental abutments were prepared to receive ceramic restorations using vertical preparation without a finish line.engjournal article1097-6841https://doi.org/10.1016/j.prosdent.2015.11.01126774314https://www.sciencedirect.com/science/article/pii/S0022391315006733?via%3Dihubhttps://pubmed.ncbi.nlm.nih.gov/26774314/open access616.314-089.28616.314-089.843Dental abutmentsDental prosthesis designOdontología (Odontología)Cirugía bucofacialPrótesis dentalAparatos y material odontológicos3213.13 Ortodoncia-Estomatología3213 Cirugía3311.03 Instrumentos Para Odontología
