The telescopic dental crown was invented in Germany. Therefore, it is also known as the German crown. The vast majority (*9 percent) of telescopic dental crowns are manufactured in Germany, according to the Hannover Dental Center..

Telescopic dental crowns consist of two parts. Primary crowns are cemented over prepped teeth for permanent placement. Secondary crowns slip over the primary ones and can be removed. They are held in place well because of the friction produced with the primary crowns..

According to the Hannover Dental Center, telescopic dental crowns provide many benefits, including prevention of bone loss, improved speech, better jaw alignment and more efficiency when chewing.

Getting telescopic crowns may require metal bows in the upper and lower jaw that span across the roof of the mouth and the back of the bottom teeth. Also, the crowns need to be removed once a day for cleaning.
