A History of Dental Ceramics Gregg Helvey DDS. Ceramics play an integral role in dentistry. Their use in dentistry dates as far back as 1889 when Charles H. Land patented the all-porcelain "jacket" crown. 1 This new type of ceramic crown was introduced in 1900s. The procedure consisted of rebuilding the missing tooth with a porcelain covering or "jacket" as Land called it.
