Rhondium One-Visit-Crown is intended for restoration of permanent teeth with a single unit crown.

Rhondium One-Visit-Crown (OVC) is a hybrid ceramic crown consisting of a fully-cured anatomical occlusal layer and an uncured sub-layer that allows customization of the OVC to the tooth preparation. When finished, the customized OVC is bonded to a prepared natural tooth. The OVC is for restoring structurally compromised posterior teeth in cases normally restored with an onlay or a partial crown in a single dental visit. The OVC is selected based on tooth location and size and therefore no impressions are necessary. The OVC is provided in designs for the upper and lower first and second premolars and the first and second molars, and each design is provided in six (6) sizes (extra-small (XS), small (S), medium (M), large (L), extra-large (XL), and extra-extra-large (XXL)). The OVC is made from a ceramic tooth shade resin material, and is provided nonsterile for single use only. Accessories to the OVC Device include the OVC Replica, an exact replica of the cured (occlusal layer) portion of the OVC. The OVC Replica is used to confirm that sufficient occlusal clearance was obtained during tooth preparation and to provide direct visualization of the overall 3D position of the OVC on the prepared tooth and the relationship with adjacent and opposing dentition. The OVC Replica is manufactured from vinyl polysiloxane impression material. OVC Wedges are accessories provided in four configurations (small right, large left and large right), and are placed interproximally to create a working surface and to block out undercuts of the preparation. The Wedges are manufactured from polyacetal resin. The Selector Keys are accessories that allow the clinician to measure the mesial-distal distance in order to choose the appropriate size OVC for the restoration, and are used during the curing of the uncured resin to prevent disturbing the placement of the crown. The Selector Keys are manufactured from polycarbonate resin. All accessories are provided nonsterile for single use only.
