Accurate procedure for simultaneous registration of gingival emergence profile and maximal intercuspal position for metal ceramic restorations

Abstract

This article describes a procedure that simultaneously registers maximal intercuspal position and gingival emergence profile. The materials used in this procedure are inexpensive, readily available, and easy to use. The clinician can inspect the framework, cast, and tissue profile before sending them to the laboratory. When this method is properly used, it allows better communication with the dental technician, saves chair time, and reduces the number of laboratory procedures as currently practiced.

Contornos y perfil de emergencia: aplicación clínica e importancia en la terapia restauradora

“…Se requiere una atención muy cuidadosa cuando se establezca un PE adecuado en la restauración definitiva para que se reduzcan no solamente las áreas retentivas que permitan la acumulación de placa bacteriana sino también la inflamación iatrogénica (40,41). Varias técnicas se han diseñado para ayudar a los clínicos y a los técnicos dentales a crear el correcto PE en las restauraciones definitivas (42)(43)(44)(45)(46). Ello incluye observación de los tejidos blandos (45,47), réplicas gingivales (25) y restauraciones provisionales (44,46,47).…”

Completely digital approach to an ovate pontic

“…When a missing maxillary incisor is replaced with a fixed dental prosthesis (FDP), an ovate pontic can be applied for esthetics and less plaque accumulation. [1][2][3][4][5][6][7][8][9][10] The established tissue beneath an interim ovate pontic may collapse when an interim FDP is removed and an impression is made. 10,11 To ensure positive contact and support of the pseudopapillae with a definitive pontic, a stone cast is scraped in this area.…”

“…10 Alternatively, a soft tissue cast and an ovate pontic index can be fabricated to transfer accurate information about the sculpted tissue to the laboratory technician. [2][3][4][5][6][7][9][10][11][12][13][14][15] These techniques, however, require additional clinical appointments and laboratory procedures.…”
