Getting an abutment from a different dentist?


I got an implant 4 months ago from a local dentist. I haven’t heard any follow up calls from my dentist so I called to the office to see if it is time to get an abutment. However, I haven’t been able to reach the doctor for 3 weeks. At this moment, I feel I should seek help from another dentist. Can I get an abutment from a different dentist that put in the implant? I don’t have any record about my implant since I cannot reach my dentist. What should I do?
