Dental bridge I
The dental bridge is a prosthetic solution to replace one or several absent teeth. Nowadays this device is used less frequently due to the excellent results obtained with dental implants. A bridge is composed of: a) the crowns fixed on to the tooth remnants; b) the pontic span; and c) the connectors that unite the bridge to the crowns. The number of teeth that can be replaced by a single bridge is calculated using Ante’s law, which states that the surface area of the teeth to be replaced must be equal to or less than the surface area of the abutment teeth. Different designs exist for the support of the pontic span on the gum, and these depend on the objective to be achieved, which may be esthetic or functional (33)(37).
