It is very difficult to determine if you have suffered a medical error. Complications of surgery are not common but do occur without surgeon error. It is extremely difficult for you as a patient to determine if your less than great result is due to medical error. There are many surgical techniques that can lead to poorer results simply due to “too much retraction” or a simple “oops” (very rare) that will never be known as it will not be dictated in the operative report.
Mixed metals should generally not be placed together in a wet environment due to corrosion possibilities but I have seen implant companies do that purposely. It still worries me.
If you had poor results, a second opinion from a different group might be helpful.
