<p>POSITIONING DEVICE FOR DENTAL IMPLANT A positioning device for dental implant has a post (1) and multiple guides (21, 22, 23, 24). The post (1) is cylindrical and has a diameter corresponding to a diameter of a hole in a dental model. The guides (21, 22, 23, 24) are mounted detachably on the post (1) and are semi-tubular tabs and each has an inner concave, an inner diameter, and an outer diameter. The guides (21, 22, 23, 24) are mounted concentrically one another. A dentist can use the positioning device to precisely position a drill bit of a drilling device on an edentulous place of a patient's jaw bone and drills a bone cavity suitable for a dental implant. The drill bit can be easily inserted into the patient's mouth without opening excessively.</p> |
