Subsequent Events [Abstract]
Subsequent Events	Subsequent EventOn March 3, 2020, we entered into a Sale and Purchase Agreement with CETP III Ivory S.a.r.1., Luxembourg to purchase all of the issued and outstanding shares of capital stock of exocad, a German dental computer-aided design/computer-aided manufacturing software company that offers fully integrated workflows to dental labs and dental practices. On April 1, 2020, we completed the acquisition for a purchase price of approximately $430.0 million in cash, subject to certain adjustments, and exocad became a wholly owned subsidiary. We are in the process of determining the preliminary allocation of the purchase price to exocad's tangible assets and liabilities assumed.
