門牙牙根斷了,又不想缺牙太久?即拔即種加臨時假牙,術前該評估的四件事|證據鏈
門牙牙根斷裂,最讓人焦慮的通常不是治療本身,而是「我會不會有一段時間門牙是空的」。 這個焦慮完全合理,而現行的做法——拔牙同時植入植體,並在當天裝上臨時假牙(即拔即種+即刻臨時修復)——確實能回應它。 但這件事在前牙美觀區有前提。 第一,「當天有牙」對美觀與舒適是有幫助的,這一點有隨機對照試驗支持。 一篇針對上顎前牙外傷後即拔即種的隨機臨床試驗記錄:即刻修復組的術後疼痛與腫脹分數顯著低於延遲修復組(p < 0.05),且粉紅美學分數(PES)顯著較高(z = 2.799,p = 0.005)。 第二,但牙齦邊緣會退,而且五年內還在持續。 一篇納入 13 項研究、421 位病人的系統性回顧與統合分析記錄:美觀區即拔即種合併骨移植後,中央頰側軟組織退縮在功能滿 1 年時為 0.33 mm(95% CI 0.21 至 0.46),滿 5 年時為 0.54 mm(95% CI 0.16 至 0.93),並明確結論退縮在 5 年內仍呈持續狀態。

FAQ
- 門牙牙根斷了,可以當天拔完就植牙、當天有臨時假牙嗎?
- 在條件符合時可以,但有明確前提。一篇隨機臨床試驗記錄,即拔即種**需要足夠的初期穩定度**才能進行植體支持的即刻臨時修復 [F1];而唇側骨板的狀態也會影響結果——**唇側骨板越薄,牙齦退縮或萎縮的風險越高** [F5]。因為初期穩定度只能在手術當下判定,合理的做法是**術前同時準備即刻修復與無法即刻修復兩種計畫**。**實際可行性需牙醫師依臨床檢查與影像(含錐狀束電腦斷層)判定。**
- 前歯の歯根が折れた場合、その日に抜歯してインプラントを埋入し、暫間歯まで入れられますか? — 条件を満たせば可能ですが、明確な前提があります。ランダム化臨床試験では、インプラント支持の即時暫間修復を行うには、抜歯即時埋入で**十分な初期固定**を得る必要があると報告されています [F1]。また、唇側骨板の状態も結果に影響し、**唇側骨板が薄いほど、歯肉退縮や萎縮のリスクが高くなります** [F5]。初期固定は手術中にしか判定できないため、**即時修復が可能な場合と、即時修復ができない場合の両方の計画を術前に用意する**ことが合理的です。**実際に可能かどうかは、歯科医師が臨床検査と画像検査(コーンビームCTを含みます)に基づいて判断する必要があります。**
- If the root of my front tooth is fractured, can it be extracted, replaced with an implant and fitted with a provisional tooth on the same day? — It may be possible when the conditions are met, but there are clear prerequisites. A randomised clinical trial reported that immediate implant placement **requires sufficient primary stability** before an implant-supported immediate provisional restoration can be provided [F1]. The state of the facial bone plate also affects the outcome: **the thinner the facial bone plate, the greater the risk of gingival recession or atrophy** [F5]. Because primary stability can only be determined during surgery, it is reasonable to **prepare both an immediate-restoration plan and a plan for when immediate restoration is not possible before treatment**. **Actual feasibility must be determined by the dentist from the clinical examination and imaging, including cone-beam computed tomography.**
