嵌體 & 嵌
What are dental inlays and onlays?
嵌體可製成瓷, 金, 或複合樹脂. 這些作品被粘到牙齒的受損區域. An inlay, which is similar to a dental filling is used inside the cusp tips of the tooth. An onlay is a more substantial reconstruction, similar to the inlay but extending out over one or more of the cusps of the tooth.
Traditionally, gold has been the material of choice for inlays and onlays. In recent years, 然而, porcelain has become increasingly popular due to its strength and color, which can potentially match the natural color of your teeth.
How are inlays and onlays applied?
Inlays and onlays require two appointments to complete the procedure. During the first visit, the filling being replaced or the damaged or decaying area of the tooth is removed, and the tooth is prepared for the inlay or onlay. To ensure proper fit and bite, an impression of the tooth is made by the dentist, and sent to a lab for fabrication. The dentist will then apply a temporary sealant on the tooth and schedule the next appointment.
At the second appointment, the temporary sealant is removed. 博士. Chan will then make sure that the inlay or onlay fits correctly. If the fit is satisfactory, the inlay or onlay will be bonded to the tooth with a strong resin and polished to a smooth finish.
Considerations for Inlays and Onlays
Traditional fillings can reduce the strength of a natural tooth by up to 50 percent. As an alternative, 嵌體和嵌, which are bonded directly onto the tooth using special high-strength resins, can actually increase the strength of a tooth by up to 75 percent. 作為一個結果, they can last from 10 至 30 年. 在某些情況下，, where the damage to the tooth is not extensive enough to merit an entire dental crown, onlays can provide a very good alternative.
