I like to use EthOss as a graft material [beta-tricalcium phosphate and calcium sulfate]. It works well and is easy to use. I recently uncovered an implant after about 3 months. About 1-2mm of the buccal threads were exposed. But the implant was solid and the biotype thick. So I placed a healing cap and will restore. My question is: if after grafting you have more threads exposed, e.g. 4-5mm, would you graft the threads again and close and wait another few months? Or would you remove the implant and start again? What is your experience and what do you advise?
