The process usually begins with a scan of the mouth. There is no tray of sticky impression material in the mouth while you try not to gag. The scan produces a 3D picture that the dentist uses to design the CAD\/CAM crowns.<\/p>\r\n
After the tooth’s prepared the dentist designs the CAD\/CAM crowns on a computer. The software shapes the CAD\/CAM crowns to fit the tooth naturally. Then the design is sent to a milling machine, which cuts the CAD\/CAM crowns from a block of dental material.<\/p>\r\n
\u2022 A digital scan replaces an impression, which is a relief if you hate that mouthful of impression paste.<\/p>\r\n
\u2022 The CAD\/CAM crowns are designed on screen. The dentist can check the shape before it is created.<\/p>\r\n
\u2022 Some clinics use chairside CAD\/CAM equipment meaning the CAD\/CAM crowns may be designed and made during the visit.<\/p>\r\n
The biggest appeal is convenience. A CAD\/CAM crown feels quicker because most of the work happens digitally and some practices can make and fit the CAD\/CAM crowns on the day.<\/p>\r\n
That is a deal if you want to avoid a temporary crown and another appointment. I personally prefer the workflow. Fewer messy impressions and less waiting just make the whole experience easier.<\/p>\r\n
A CAD\/CAM crown needs to sit against the prepared tooth and work with the teeth around it. Digital design gives the dentist a view while planning the restoration, which helps the dentist adjust the shape before the CAD\/CAM crown reaches the mouth.<\/p>\r\n
CAD\/CAM systems work with dental materials for CAD\/CAM crowns. Ceramic is popular when appearance matters because it can be matched closely to teeth. Zirconia is another option when strength is a concern.<\/p>\r\n
The right material depends on where the CAD\/CAM crown sits and how much chewing pressure that tooth handles. A front tooth has demands from a back molar. That is pretty straightforward.<\/p>\r\n
CAD\/CAM crowns work well if you want a precise digital workflow and when available a same\u2011day restoration. Still not every tooth or situation is suited to chairside CAD\/CAM treatment. Some cases need laboratory work because the CAD\/CAM crown requires detailed customisation.<\/p>\r\n
