April 22 (Reuters) - Align Technology Inc (ALGN.O) posted a better-than-expected quarterly profit, helped by higher shipments of its Invisalign orthodontic cases, sending its shares up 5 percent in pre-market trade.

The company reported first-quarter profits of $15.5 million excluding items, or 20 cents a share, compared with $3.2 million, or 5 cents a share in the year-ago period.

Revenue for the quarter rose 28.5 percent to $90.1 million, the company said in a statement.

Analysts on average were expecting the company to earn 13 cents a share, on revenue of $86.9 million, according to Thomson Reuters I/B/E/S.

Invisalign case shipments for the first quarter were 63,600 compared with 50,100 a year ago.

The company said it expects second-quarter revenues to be between $88.0 million and $91.0 million and profit in the range of 12 cents to 14 cents a share.

The company said it will introduce a consumer rebate program in its second-quarter that will hurt gross margins for the quarter.

Shares of Align were trading at $19.70 in Thursday pre-market trade. They closed at $18.80 Wednesday on Nasdaq. (Reporting by Krishnakali Sengupta in Bangalore; Editing by Roshni Menon)
