门牙牙根断了,又不想缺牙太久?即刻种植加临时假牙,术前该评估的四件事|證據鏈
门牙牙根断裂,最让人焦虑的通常不是治疗本身,而是“我会不会有一段时间门牙是空的”。 这个焦虑完全合理,而现行的做法——拔牙同时植入种植体,并在当天装上临时假牙(即刻种植+即刻临时修复)——确实能回应它。 但这件事在前牙美观区有前提。 第一,“当天有牙”对美观与舒适是有帮助的,这一点有随机对照试验支持。 一篇针对上颌前牙外伤后即刻种植的随机临床试验记录:即刻修复组的术后疼痛与肿胀分数显著低于延迟修复组(p < 0.05),且粉红美学评分(PES)显著较高(z = 2.799,p = 0.005)。 第二,但牙龈边缘会退,而且五年内还在持续。 一篇纳入 13 项研究、421 位患者的系统评价与 Meta 分析记录:美观区即刻种植合并骨移植后,中央颊侧软组织退缩在功能满 1 年时为 0.33 mm(95% CI 0.21 至 0.46),满 5 年时为 0.54 mm(95% CI 0.16 至 0.93),并明确结论退缩在 5 年内仍呈持续状态。

FAQ
- 门牙牙根断了,可以当天拔完就种植牙、当天有临时假牙吗?
- 在条件符合时可以,但有明确前提。一篇随机临床试验记录,即刻种植**需要足够的初期稳定度**才能进行种植体支持的即刻临时修复 [F1];而唇侧骨板的状态也会影响结果——**唇侧骨板越薄,牙龈退缩或萎缩的风险越高** [F5]。因为初期稳定度只能在手术当下判定,合理的做法是**术前同时准备即刻修复与无法即刻修复两种计划**。**实际可行性需牙医依临床检查与影像(含锥形束计算机断层扫描)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.**
