CY2018	us-gaap	Use Of Estimates UseOfEstimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.

The Company has elected to classify the cash flow from derivative instruments in the same category as the cash flows from the items being hedged.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Sales, value add, and other taxes collected concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense.</span></div><div style="text-indent:18pt;text-align:justify;"><span><br/></span></div><div style="text-indent:18pt;text-align:justify;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:Times New Roman;font-size:10pt;line-height:120%;">For most of consumables, technologies, and equipment, the Company transfers control and recognizes a sale when products are shipped from the Company's manufacturing facility or warehouse to the customer (distributors and direct to dentists). For contracts with customers that contain destination shipping terms, revenue is not recognized until risk has transferred and the goods are delivered to the agreed upon destination. The amount of consideration received and revenue recognized varies with changes in marketing incentives (e.g. discounts, rebates, free goods) and returns offered to customers and their customers. When the Company gives customers the right to return eligible products and receive credit, returns are estimated based on an analysis of historical experience. However, returns of products, excluding warranty related returns, are infrequent and insignificant. The Company adjusts the estimate of revenue at the earlier of when the most likely amount of consideration can be estimated, the amount expected to be received changes, or when the consideration becomes fixed. Consideration received from customers in advance of revenue recognition is classified as deferred revenue.</span></div><div style="text-indent:18pt;text-align:justify;"><span><br/></span></div><div style="text-indent:18pt;text-align:justify;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:Times New Roman;font-size:10pt;line-height:120%;">Depending on the terms of the arrangement, the Company may also defer the recognition of a portion of the consideration received when performance obligations are not yet satisfied (e.g., free extended maintenance/service contracts, software and licenses, customer loyalty points and coupon programs). The Company uses an observable price, typically average selling price, to determine the stand-alone selling price for separate performance obligations. The Company determines the stand-alone selling price, based on Company geographic sales locations' database of pricing and discounting practices for the specific product or service when sold separately, and utilizes this data to arrive at average selling prices by product. Revenue is then allocated proportionately, based on the determined stand-alone selling price, to the unsatisfied performance obligation, which is deferred until satisfied. At December 31, 2018, the Company had $29.3 million of deferred revenue recorded in Accrued liabilities in the Consolidated Balance Sheets. The Company expects to recognize significantly all of the deferred revenue within the next twelve months.</span></div><div style="text-indent:18pt;text-align:justify;"><span><br/></span></div><div style="text-indent:18pt;text-align:justify;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:Times New Roman;font-size:10pt;line-height:120%;">The Company has elected to account for shipping and handling activities as a fulfillment cost within the cost of products sold, and records shipping and handling costs collected from customers in net sales. The Company has adopted two practical expedients: the “right to invoice” practical expedient, which allows us to recognize revenue in the amount of the invoice when it corresponds directly with the value of performance completed to date; and relief from considering the existence of a significant financing component when the payment for the good or service is expected to be one year or less.</span></div><div style="text-indent:18pt;text-align:justify;"><span><br/></span></div><div style="text-indent:18pt;text-align:justify;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:Times New Roman;font-size:10pt;line-height:120%;">The Company offers discounts to its customers and distributors if certain conditions are met. Discounts are primarily based on the volume of products purchased or targeted to be purchased by the customer or distributor. Discounts are deducted from revenue at the time of sale or when the discount is offered, whichever is later. The Company estimates volume discounts based on the individual customer’s or distributor's historical and estimated future product purchases.</span></div><div style="text-indent:18pt;text-align:justify;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:Times New Roman;font-size:10pt;line-height:120%;">Certain of the Company’s customers are offered cash rebates based on targeted sales increases. The Company estimates rebates based on the forecasted performance of a customer and their expected level of achievement within the rebate programs. In accounting for these rebate programs, the Company records an accrual and reduces net sales ratably as sales occur over the rebate period. The Company updates the accruals for these rebate programs as actual results and updated forecasts impact the estimated achievement for customers within the rebate programs.</span></div><div style="text-indent:18pt;text-align:justify;"><span><br/></span></div><div style="text-indent:18pt;text-align:justify;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:Times New Roman;font-size:10pt;line-height:120%;">A portion of the Company’s net sales is comprised of sales of precious metals generated through its precious metal dental alloy product offerings. As the precious metal content of the Company’s sales is largely a pass-through to customers, the Company uses its cost of precious metal purchased as a proxy for the precious metal content of sales, as the precious metal content of sales is not separately tracked and invoiced to customers. The Company believes that it is reasonable to use the cost of precious metal content purchased in this manner since precious metal alloy sale prices are typically adjusted when the prices of underlying precious metals change.</span></div>
