How long after tooth extraction can a dental implant be placed? Assessing immediate, early and delayed placement｜證據鏈
The timing of implant placement after tooth extraction can broadly be understood as three timelines: placing the implant at the time of extraction, placing it relatively early after initial healing, or waiting for the site to heal further before placement. Names and time thresholds are not necessarily entirely consistent across research. For example, one review comparing immediate and delayed single-tooth implant placement defined delayed placement as at least 3 months after extraction. This was the comparison threshold in that study, not a timetable that every patient must follow. The actual assessment must consider the extraction socket, buccal bone wall, soft tissue, planned implant position and overall risk together. In particular, studies of immediate and early placement in the aesthetic zone have generally involved selected, lower-risk cases with an intact buccal bone wall.

FAQ
- If an implant can be placed on the day of extraction, does that mean immediate placement is suitable?
- This cannot be decided merely because the implant ‘will fit’. The more cautious conclusion from comparative studies in the aesthetic zone is limited to lower-risk cases with an intact buccal bone wall, and the certainty of the evidence remains low [F2]. What you need is an explanation of suitability after an individual examination.
- 抜歯当日にインプラントを埋入できるなら、即時埋入に適しているということですか？ — 「埋入できる」ことだけでは判断できません。審美領域の比較研究から比較的慎重に導ける結論は、リスクが低く、頬側骨壁が保たれた症例に限られ、エビデンスの確実性もなお低いものです [F2]。必要なのは、個別検査後の適応に関する説明です。
