The CONUS per diem rate for an area is actually three allowances: the lodging allowance, the meals allowance and the incidental expense allowance. Most of the CONUS (approximately 2600 counties) are covered by the standard CONUS per diem rate of $140 ($89 lodging, $51 meals and incidental expenses).
Inlays are made from porcelain or gold, and help to hold the rest of the tooth together so that it can be used to bite and chew normally. Onlays. Dental onlays repair not only the chewing surfaces of back teeth, but also one or more of the cusps. The cusps are the raised points of the tooth located on the outer edges.
All of the benefits of an inlay are present in the onlay restoration. The onlay allows for conservation of tooth structure when the only alternative is to totally eliminate cusps and perimeter walls for restoration with a crown.
