Description

Technical Field

[0001] The utility model relates to the technical field of oral medicine, in particular to a device for measuring a 3D implantation site of a tooth implant. Background Art

[0002] Dental implants have gradually become the preferred restoration method for patients with edentulous teeth because they can achieve functions, structures and aesthetic effects similar to natural teeth. Implant technology has been widely used in clinical treatment, and a large number of implant cases have emerged, but also a large number of problems. At this time, people began to pay attention to the risk control and treatment of implants, and the principle of implant treatment has also changed from the original "surgery-oriented implant denture restoration" to "restoration-oriented implant denture restoration". Dental implants include implants in the bone and upper restoration structures. The three-dimensional position of the implant in the bone is determined by the position of the restoration simulating the natural tooth. Poor three-dimensional position of the implant and poor restoration design will have a negative effect on the long-term stability of bone integration and soft tissue. However, to obtain the ideal three-dimensional position during surgery, sufficient field of view, precise spatial analysis, rich experience and superb technical level are required.

[0003] The positioning markers equipped with existing different implant systems are basically designed similar to rulers. The distance between two adjacent teeth in the edentulous area is measured, and then the surgeon calculates the position of the midpoint. However, it is impossible to quickly determine the restoration gap and intuitively locate the midpoint of the gap. In addition, it is often difficult to accurately measure the effective size of the mesiodistal restoration gap due to the inclination of adjacent teeth. Therefore, a 3D implant site measurement device for dental implants is proposed to solve the above problems. Utility Model Content
