Revenue from Contract with Customer [Text Block]	Note 7 . Revenue Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for promised goods or services. The Company’s performance obligations are satisfied either over time or at a point in time. Revenue from performance obligations that are transferred to customers over time accounted for approximately 14% three March 31, 2018. The Company's system sale arrangements generally contain multiple products and services. For these bundled sale arrangements, the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s system sale arrangements include a combination of the following performance obligations: The system and software license (considered as one For the Company’s system sale arrangements that include an extended service contract, the period of service commences at the expiration of the Company’s standard warranty offered at the time of the system sale. The Company considers the extended service contracts terms in the arrangements that are legally enforceable to be performance obligations. Other than extended contract services and training, the Company satisfies all of the performance obligations at a point in time. System, system accessories (hand pieces), training, and services are also sold on a stand-alone basis, and related performance obligations are satisfied over time as the services are performed. For contracts with multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation, on a relative basis using its standalone selling price. The stated contract value is the transaction price to be allocated to the separate performance obligations.

Service revenue is recognized over time as the customers benefit from the service throughout the service period. Revenue related to services performed on a time-and-materials basis is recognized when performed.

Earnings Per Share [Text Block]	Note 10 . Net Loss Per Share Basic net income (loss) per share is computed using the weighted-average number of shares outstanding during the period. In periods of net income, diluted shares outstanding include the dilutive effect of in-the-money equity awards (stock options, restricted stock units, performance stock units and employee stock purchase plan contributions), which is calculated based on the average share price for each fiscal period using the treasury stock method. In accordance with ASC 718, Diluted earnings per share is the same as basic earnings per share for the periods in which the Company had a net loss because the inclusion of outstanding common stock equivalents would be anti-dilutive. The following table sets forth the computation of basic and diluted net income (loss) and the weighted average number of shares used in computing basic and diluted net income (loss) per share (in thousands, except per share data): Three months ended March 31, 2018 Three months ended March 31, 2017 Numerator: Net loss $ (2,032 ) $ (1,022 ) Denominator: Weighted-average shares outstanding in basic calculation 13,587 13,840 Add: dilutive effect of potential common shares — — Weighted-average shares used in computing diluted net income per share 13,587 13,840 Net loss per share: Net loss per share, basic and diluted $ (0.15 ) $ (0.07 ) Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the year. Diluted net loss per common share is the same as basic net loss per common share, as the effect of the potential common stock equivalents is anti-dilutive and as such is excluded from the calculations of the diluted net loss per share. The following numbers of shares outstanding, prior to the application of the treasury stock method, were excluded from the computation of diluted net loss per common share for the period presented because including them would have had an anti-dilutive effect (in thousands): Three Months Ended March 3 1 , 201 8 201 7 Options to purchase common stock 807 1,088 Restricted stock units 396 384 Performance stock units 23 164 Employee stock purchase plan shares 34 49 Total 1,260 1,685
