The method of inlays for multiple missing teeth varies from person to person, and also varies depending on the missing part, whether it is the missing free end or the missing front incisors, depending on the missing part, there will be different inlays, and there are about three restorative methods: 1, movable denture, also known as movable dentures; 2, fixed denture, also known as porcelain restoration; 3, dental implant restoration. Among these three restorations, the disadvantages of movable denture restoration are very obvious, patients must take them off every day, and chewing efficiency is also relatively low, so patients hate the characteristics of movable denture to take off and clean every day. But fixed denture also has the disadvantage of grinding the affected teeth around two healthy abutment teeth, so fixed denture used after 10-15 years, is also recommended that patients go to the regular hospital to remove, re-fixed porcelain crown restoration. The cost of porcelain teeth is relatively high in the early stage, but since there is no need to replace the implants at a later stage, dental implants are currently the preferred method of restoring missing teeth.
