When do you need to replace the implant analog?

Usually we have seen many doctors choose an implant analog at random after taking the model in the second stage of implantation and hand it over to the processing factory to make dental crown. Then after the factory is finished, when the doctor puts the teeth on the patient, he will find that the teeth cannot fit into the patient's mouth very tightly. Usually in such a situation, the doctor's first thought may be that the quality of the processing plant is not up to standard, or the technicians in the processing plant are not skilled enough. In addition, some doctors may feel that they may have made a deviation when making the model, and the impression may be inaccurate. Therefore, some doctors will ask the processing factory to remake the teeth, and some doctors will retake the model for the patient. But after the teeth were made, the problem was still not solved. What is the problem?

In fact, we implant doctors are more likely to make a clinical mistake, that is, after taking the model for the patient, we did not carefully check whether the replacement body has been deformed when selecting the replacement body of the implant.

Because of the consideration of outpatient clinical charges and outpatient operating costs, many outpatient clinics use the substitutes repeatedly during the second-stage restoration of implants. The implant manufacturer has explained to the user when making the analog: the analog can be used repeatedly, but if the analog is deformed, a new one should be replaced. But I have seen many implant doctors ignore this point, not carefully checking whether the replacement is qualified before sending it to the processing plant.

Deformations of the prosthesis that can affect the quality of the tooth fabrication mainly occur at the neckline of the prosthesis.

Let's take a look at the photo below:

This is a photo of the interface of the used analog. From the photo, the interface has no obvious deformation, and the internal hexagonal structure is intact. Such an analog can be used again.

Let's see another photo. In the photo below, we can see that the interface of the analog is worn and deformed.

In the photo below, although the interface of the analog is intact and not deformed, the internal hexagonal structure has been severely worn.

These analogs can't be used anymore when these situations happened. The doctor should replace the analog.

Dental implant is a high-tech and high-precision restoration technology, and any error will lead to the failure of the final restoration.

As an implant doctor, on the one hand, we must try our best to do any clinical operation accurately and accurately. On the other hand, we cannot continue to use the analog that are severely deformed, and we should check and replace them in time.
