I have patient 15 years old patient,who complain in gum pain (Fistula is in the furaction and is nonrestorable).
Tooth #19 had a RCT  done couple years ago, and now its failed and needs and extraction. On PA x-ray there is a 5-6 mm cyst on mesial root, distal 3-4 mm, and furcation is involvment, and tooth hopeless, and needs to be extracted.
When do you think best time to place implants in children? How do you know when a childs growth is complete and safe to place implants.
thank you.
