Technology Partner Innovations, LLC ("TPI")	Technology Partner Innovations, LLC ("TPI")In fiscal 2019, we entered into an agreement with Cure Partners to form TPI, which offers a cloud-based practice management software, NaVetor, to its customers. Patterson and Cure Partners each contributed net assets of $4,000 to form TPI. We determined that TPI is a variable interest entity, and we consolidate the results of operations of TPI as we have concluded that we are the primary beneficiary of TPI. Patterson and Cure Partners each contributed additional net assets of $1,000 during fiscal 2022 to TPI. During fiscal 2022, 2021 and 2020, net loss attributable to the noncontrolling interest was $1,496, $872 and $921, respectively. Since TPI was formed, there have been no changes in ownership interests. As of April 30, 2022, we had noncontrolling interests of $959 on our consolidated balance sheets
