This utility model relates to the field of dental technology. A dental aligner with a tubular functional attachment includes a clear aligner base and a tubular functional attachment for connecting a traction attachment. The tubular functional attachment is fixed to the buccal side of the clear aligner base. The tubular functional attachment includes at least one of a horizontal tubular functional component and a longitudinal tubular functional component. The horizontal tubular functional component is used to fix the crown of the clear aligner base to the buccal side; the longitudinal tubular functional component is used to fix the connection between adjacent crowns of the clear aligner base to the buccal side. This utility model, by fixing the tubular functional attachment to the clear aligner base, facilitates the application of force to the clear aligner in different mechanical ways, thereby applying force to the teeth.
