A review of the drilling protocol and surgical report indicate the case was properly planned and no defects were noted on the returned surgical guide.Dr.Cleber silva reviewed the case and stated this was a case with severe peridontal disease and a lot of missing bone which should have warranted immediate placement.The scan the doctor sent in was 3 months old, meaning that in addition to bone already lost at the time of scanning, a site with periodontal disease can undergo rapid and accelerated bone loss in 3 months, particularly if localized infections occur, which is quite common.Dr.Silva's professional opinion is either (1) more bone was lost in the 3 months between scanning and surgery or (2) bone was lost during extraction.The surgical guide was not the cause of the problem.
