Intraoral scanning rod processed by sand blasting

Technical Field

The utility model relates to a dental medical instrument technical field, concretely relates to intraoral scanning rod through sand blasting.

Background

The dental implant is structurally divided into three parts, namely an abutment, an implant and a screw, in the process of implanting the dental implant, a dentist firstly implants the dental implant into an alveolar bone of an edentulous part in a surgical operation mode, after the implant and the alveolar bone are healed, the implant is connected with a conversion abutment, and a ceramic crown is fastened and fixed on the conversion abutment to complete the process of implanting the false tooth. The German Branemark made a first titanium nail implant in the mouth of a rabbit in 1965 by using pure titanium metal, and later made a functional test on dogs for 10 years, and all the results obtained in vivo experiments. Compared with the traditional fixed bridge and movable false tooth restoration, the dental implant has the advantages of beauty, comfort, reliability and the like, becomes the third pair of teeth of a patient with a defective dentition and is widely concerned.

After a doctor implants an implant in a patient's mouth, the doctor needs to wear a base station and a crown bridge prosthesis on the upper part of the implant, if the doctor selects a standard base station, a technician can directly prepare the standard base station and scan and design the crown bridge prosthesis, if the doctor selects to manufacture a personalized base station, the information of the implant in the patient's mouth is transferred out through a scanning rod because the personalized base station is designed through computer software; with the intraoral scanner, the scanning rod can be mounted directly on the implant to directly scan the implant information in the patient's mouth.
