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.
Bicuspids, also called pre-molars, typically have two cusps as shown by the two blue asterisks in the top image. When we refer to crowns, onlays, and inlays, we are referring to whether we need to restore the cusp of the tooth, and if so, whether it is all of the cusps or some of the cusps. When a tooth has been severely weakened or fractured, we will usually place a crown, which covers all of the cusps.
