Thanks, Joe. Now for our Q1 financial results. Total revenues for the first quarter were $997.4 million, up 4.3% from the prior quarter and up 5.8% from the corresponding quarter a year ago. On a constant currency basis, Q1 '24 revenues were impacted by favorable foreign exchange of approximately $10 million or approximately 1% sequentially and were unfavorably impacted by approximately $4.8 million year-over-year or approximately 0.5%. For Clear Aligners, Q1 revenues of $817.3 million were up 4.5% sequentially, primarily from higher ASPs and higher volumes. On a year-over-year basis, Q1 Clear Aligner revenues were up 3.5%, primarily due to higher volumes and ASPs and increased non-case revenues. For Q1, Invisalign ASPs for comprehensive treatment were up sequentially and up year-over-year. On a sequential basis, ASPs primarily reflect higher additional aligners and price increases and the variable impact of foreign exchange partially offset by a product mix shift to lower ASP products. On a year-over-year basis, the increase in comprehensive ASPs primarily reflect higher additional aligners and price increases partially offset by a product mix shift to lower ASP products and higher discounts and the unfavorable impact from foreign exchange. For Q1, Invisalign ASPs for non-comprehensive treatment were down sequentially and year-over-year. On a sequential basis, the decline in ASPs reflect unfavorable country mix shift and higher discounts, partially offset by the favorable impact from foreign exchange. On a year-over-year basis, the decrease in non-comprehensive ASPs reflect the product mix shift to lower ASP products, unfavorable country mix shift and higher discounts, partially offset by lower net revenue deferrals. As a reminder, we announced about a 5% global price increase for some Invisalign products across most markets effective January 1, 2024. This price increase did not include Invisalign Comprehensive Three and Three products. Invisalign Comprehensive Three and Three product is available in North America and in certain markets in EMEA and APAC, most recently launching in French territories and in the Middle East. We are pleased with the continued adoption of the Invisalign Comprehensive Three and Three product and anticipate it will continue increasing, providing doctors the flexibility they want and allowing us to recognize more revenue upfront with deferred revenue being recognized over a shorter period of time compared to our traditional Invisalign Comprehensive product. Q1 '24 Clear Aligner revenues were impacted by a favorable foreign exchange of approximately $8.4 million or approximately 1% sequentially. On a year-over-year basis, Clear Aligner revenues were unfavorably impacted by foreign exchange of approximately $3.9 million or approximately 0.5%. Clear Aligner deferred revenues on the balance sheet decreased $26.7 million or 2% sequentially and increased $15.8 million or 1.2% year-over-year and will be recognized as the additional aligners are shipped. Q1 '24 Systems and Services revenue of $180.2 million were up 3.1% sequentially, primarily due to increased nonsystems revenues, mostly related to upgrades and higher ASPs, partially offset by lower volumes. Q1 '24 systems and Services revenue were up 17.5% year-over-year primarily due to increased nonsystems revenues, mostly related to upgrades, higher scanner volumes and higher services revenues from our larger base of scanners sold. CAD/CAM and Services revenue for Q1 represents approximately 51% of our Systems and Services business. Q1 '24 Systems and Services revenues were favorably impacted by foreign exchange of approximately $1.5 million or approximately 0.9% sequentially. On a year-over-year basis, Systems and Services revenues were unfavorably impacted by foreign exchange of approximately $0.9 million or approximately 0.5%. Systems and Services deferred revenues on the balance sheet was down $14.3 million or 5.5% sequentially and down $25.3 million or 9.4% year-over-year primarily due to the recognition of services revenues, which will -- which is recognized ratably over the service period. The decline in deferred revenues both sequentially and year-over-year reflects the shorter duration of service contracts with initial scanner purchases. As our scanner portfolio expands and we introduce new products, we increased the opportunities for customers to upgrade and make trade, in addition to other scanner leasing and rental programs. Developing new capital equipment opportunities to meet the digital transformation needs of our customers and our DSO partners is a natural progression for our equipment business with a large and growing base of scanners sold. We're pleased to be able to leverage our technological innovations and operational capabilities and efficiencies to provide different types of go-to-market models to our customers, such as rentals and leasing, selling the way that our customers want to buy. Moving on to gross margin. First quarter overall gross margin was 70%, approximately flat sequentially and year-over-year. Overall gross margin was favorably impacted by foreign exchange by approximately 0.3 points sequentially and unfavorably impacted by approximately 0.1 points on a year-over-year basis. Clear Aligner gross margin for the first quarter was 70.9%, down 0.3 points sequentially due -- primarily due to higher manufacturing spend, partially offset by higher ASP. Clear Aligner gross margin for the first quarter was down 0.8 points year-over-year, primarily due to higher manufacturing spend, partially offset by favorable ASP. Systems and Services gross margin for the first quarter was 65.9%, up 1.1 points sequentially due to higher ASP partially offset by manufacturing variances. Systems and Services gross margin for the first quarter was up 4.3 points year-over-year, primarily due to higher ASP, lower service and manufacturing costs. Q1 operating expenses were $543.7 million, up 9.2% sequentially and 3.1% year-over-year. On a sequential basis, operating expenses were up by $45.7 million from higher incentive compensation and consumer marketing spend, partially offset by restructuring and other charges not recurring in Q1. Year-over-year, operating expenses increased by $16.5 million, primarily due to our continued investments in sales and R&D activities and higher incentive compensation. On a non-GAAP basis, excluding stock-based compensation, amortization of acquired intangibles related to certain acquisitions and restructuring and other charges, operating expenses were $506.1 million, up 13.3% sequentially and up 3.2% year-over-year. Our first quarter operating income of $154.1 million resulted in an operating margin of 15.5% down 2.5 points sequentially and up 1.3 points year-over-year. The sequential decrease in operating margin is primarily attributed to investments in our go-to-market teams and higher incentive compensation. The year-over-year increase in operating margin is primarily attributed to operating leverage and proactively managing our costs, partially offset by unfavorable impact from foreign exchange of approximately 0.7 points. On a non-GAAP basis, which excludes stock-based compensation, amortization of intangibles related to certain acquisitions and restructuring and other charges, operating margin for the first quarter was 19.8%, down 4 points sequentially and up 1.3 points year-over-year. Interest and other income expense net for the first quarter was an income of $4.3 million, compared to an income of $1.3 million in Q4 of '23 and an income of $1.1 million in Q1 of '23, primarily driven by a gain on our equity investments and net interest income and offset by unfavorable foreign exchange. The GAAP effective tax rate in the first quarter was 33.7% compared to 28.3% in the fourth quarter and 34.8% in the first quarter of the prior year. The first quarter GAAP effective tax rate was higher than the fourth quarter effective tax rate, primarily due to discrete tax benefits recognized in Q4 of '23, partially offset by increased earnings in low tax jurisdictions in Q1 of '24. Our non-GAAP effective tax rate in the first quarter was 20%, which reflects our long-term projected tax rate. First quarter net income per diluted share was $1.39, down sequentially $0.24 and up $0.26, compared to the prior year. Our EPS was not impacted on a sequential basis from foreign exchange. Our EPS was unfavorably impacted by $0.09 on a year-over-year basis due to foreign exchange. On a non-GAAP basis, net income per diluted share was $2.14 for the first quarter, down $0.28 sequentially and up $0.32 year-over-year. Moving on to the balance sheet. As of March 31, 2024, cash, cash equivalents and short term and long-term marketable securities were $902.5 million, down sequentially $78.2 million and down $18.9 million year-over-year. Of our $902.5 million balance, $217.5 million was held in the U.S. and $685 million was held by our international entities. In January 2024, we received approximately 37,000 shares of our common stock upon final settlement of the $250 million accelerated share repurchase from Q4 of '23. In total, we repurchased approximately 1.1 million shares at an average price per share of $230.13 under the Q4 ASR contract. We have $650 million available for repurchase of our common stock under our January 2023 repurchase program. During Q2 '24, we expect to repurchase up to $150 million of our common stock through either a combination of open market repurchase or an accelerated stock repurchase agreement. Q1 accounts receivable balance was $950.7 million, up sequentially. Our overall days sales outstanding was 86 days up approximately 1 day sequentially and up approximately 3 days as compared to Q1 last year. Cash flow from operations for the first quarter was $28.7 million. Capital expenditures for the first quarter were $9.4 million, primarily related to our continued investments to increase aligner manufacturing capacity and facilities. Free cash flow, defined as cash flow from operations less capital expenditures, amounted to $19.3 million. We're continuing to use our healthy balance sheet to drive growth and profitability. During the quarter, we continued to make disciplined investments in our strategic growth drivers. We completed the acquisition of Cubicure, which will enable us to scale our 3D printing operations to eventually direct print millions of custom appliances per day, and we exited the quarter with a healthy cash flow position and no long-term debt, maintaining a strong position to support our additional $75 million investment in our DSO partner Heartland Dental and our $150 million stock buyback. Now turning to our outlook. Assuming no circumstances occur beyond our control, we provide the following framework for Q2 and fiscal 2024. For Q2 '24, we provide the following business outlook. For Q2 '24, we expect worldwide revenues to be in the range of $1.030 billion to $1.050 billion. We expect Clear Aligner volume to be up sequentially and Clear Aligner ASP to be down slightly sequentially, primarily as a result of unfavorable foreign exchange. We expect Systems and Services revenue to be up sequentially as we continue to ramp iTero Lumina in Q2 2024. We expect Q2 '24 GAAP operating margin and non-GAAP operating margin to be slightly above Q1 '24 GAAP and non-GAAP operating margins, respectively. For fiscal '24, we provide the following business outlook. We expect fiscal '24 total revenue to be up 6% to 8% versus 2023, which is higher than our prior outlook of up mid-single-digit growth compared to 2023. The increase in our 2024 revenue outlook reflects our Q1 results, Q2 outlook and continued execution of our growth strategies. We anticipate that the incremental revenue reflected in our 2024 outlook will be roughly split 50-50 between our 2 operating segments. We expect fiscal 2024 Clear Aligner ASPs to be slightly up year-over-year. We expect fiscal 2024 GAAP operating margin and non-GAAP operating margin to be slightly above the 2023 GAAP operating margin and non-GAAP operating margin, respectively. We expect our capital -- our investments in capital expenditures for fiscal 2024 to be approximately $100 million. Capital expenditures primarily relate to building construction and improvements as well as manufacturing capacity in support of our continued expansion. With that, I'll turn it back over to Joe for final comments. Joe?
