Inlays and Onlays
Inlays and onlays are indirect restorations fabricated outside the mouth and cemented to the cavity prepared on a tooth. They are offered as minimally invasive options at Kamala Dental Specialty Hospital.
Inlays and onlays are used mainly in molars or premolars, when the tooth has experienced too much damage to support a basic filling, but not so much damage that a crown is necessary. They have better strength and durability compared to bulky fillings.
The key comparison between them is the amount and part of the tooth that they cover. An inlay will incorporate the pits and fissures of a tooth, mainly encompassing the chewing surface between the cusps.
An onlay will involve one or more cusps being covered. If all cusps and the entire surface of the tooth is covered, this restoration is known as a crown.
Inlay or onlay wax patterns are made directly from the mouth or from cast created with an impression from mouth using wax and then creating a metal, composite or ceramic pattern using lost wax technique.
CAD CAM technique
CAD-CAM (Computer Aided Design-Computer Aided Manufacture) is used for fabrication of inlays and onlays. It is possible to deliver these indirect restorations in a single or multiple visits. It works by first making a virtual 3D impression produced by an intra-oral scan. The 3D image is then sent to the chosen software program, to create a digital wax up and milling is then done through CAD CAM software.
At KDSH, our clinicians will evaluate the status of your broken tooth and suggest you the best feasible options in as less time as plausible.
