Can an implant be placed on the day of extraction? First assess infection, bone wall and smile line｜證據鏈
Implant placement on the day of extraction can be discussed in carefully selected, suitable cases, but it is not appropriate after every extraction. Assessment should determine whether infection in the socket can be thoroughly debrided, whether the facial bone wall is intact and thick enough, and whether primary implant stability can be achieved. For anterior teeth, the extent of gingival display when you smile should also be recorded. However, the six evidence cards in this article do not directly compare outcomes for high and low smile lines, so smile line cannot be presented as an indication threshold or a predictor of failure for immediate placement. Immediate implant placement also does not mean that a fixed tooth you can bite on will necessarily be fitted the same day: placing the implant, deciding when to fit the restoration, and deciding when to apply occlusal loading are separate decisions.

FAQ
- Does infection always prohibit immediate placement?
- No. Limited controlled studies suggest similar survival after thorough debridement, but evidence is only non-randomised. [F1] Extent, post-debridement walls and stability still decide; absence of pain is insufficient.
- 感染窩では必ず即時埋入できませんか？ — 必ずしもそうではありません。徹底的な掻爬後に未感染窩と近い生存結果を示した限定的な対照研究がありますが、非ランダム化研究だけです。[F1] 感染範囲、骨壁、初期固定を確認し、痛みがないことだけでは判断しません。
