A dental implant guide plate comprises an upper guide plate, a lower guide plate, a positioning column and a tongue sleeve; the positioning column is arranged between the upper guide plate and the lower guide plate and used for keeping the upper guide plate and the lower guide plate to keep a preset distance; the tongue sleeve is arranged in a space between the upper guide plate and the lower guide plate, the tongue sleeve is provided with a cavity with an opening towards one end, the cavity wall of the cavity close to the lower guide plate is a flat-plate cavity wall, and the cavity wall of the cavity close to the upper guide plate is a circular-arc cavity wall.

In one embodiment, the upper guide plate and the lower guide plate are respectively provided with a corresponding planting puncture part, and the top end of the tongue sleeve is 3-8 mm away from the planting puncture part.

In one embodiment, the number of the positioning columns is two, and the positioning columns are respectively arranged on two sides of the tongue sleeve.

In one embodiment, the positioning column is in the shape of a lath, the cross section of the positioning column in the length direction of the lath is a hyperbolic curve, and the cross section of the positioning column in the width direction of the lath is an ellipse.

In one embodiment, the tongue sheath is made of silica gel.

The utility model provides a kind plant tooth baffle is through setting up the tongue cover between last baffle and lower guide, through the patient tongue that probably constantly moves in the tongue cover constraint operation, can reduce the interference of planting kind plant tooth operation in-process patient tongue to tooth planting to for the operation is carried out smoothly and is provided convenience, improves operation efficiency and success rate.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In an embodiment of the present invention, a dental implant guide is provided, as shown in fig. 1 and 2, including an upper guide 100, a lower guide 200, a positioning column 300 and a tongue cover 400; the positioning column 300 is disposed between the upper guide plate 100 and the lower guide plate 200, and is used for keeping the upper guide plate 100 and the lower guide plate 200 at a predetermined interval; the tongue sleeve 400 is arranged in the space between the upper guide plate 100 and the lower guide plate 200, the tongue sleeve 400 is provided with a cavity with an opening towards one end, the cavity wall of the cavity close to the lower guide plate 200 is a flat-plate cavity wall, and the cavity wall of the cavity close to the upper guide plate 100 is a circular-arc cavity wall. The upper guide plate 100 and the lower guide plate 200 are both suitable for sleeving the dental implant guide plate on the gum of a patient, and after the specific shapes of the oral cavity and the gum of the patient are accurately measured, the personalized upper guide plate 100 and the personalized lower guide plate 200 are manufactured by adopting a 3D printing technology. The upper guide plate 100 and the lower guide plate 200 are separated by the positioning column 300, so that the oral cavity of the patient is kept open, and a surgical operation space is formed. The tongue cover 400 is arranged in the operation space and can effectively prevent the tongue from contacting the gum in the operation.
