One very common specialty crown is the dental implant crown. While it is usually fabricated in the same way as a traditional dental crown, it may require additional preparation with models and temporaries prior to fabricating the permanent crown. The dental implant crowns are placed on a dental implant abutment (custom or prefabricated) rather than a tooth and these many times require additional steps to enhance the soft tissue (gums) around the abutment for a more cosmetic result. Another common specialty crown is a splinted dental crown.
