FAQ

“牙钉”是正式名称吗？
**不是。** 台湾分类数据库查询“牙钉”返回 0 笔 [F6]，台北核定表全文也没有这两个字 [F7]。请医生说出正式名称：牙柱心、矫正微螺钉／TAD，或人工牙根 [F3][F4][F5]。
「歯のピン」は正式名ですか？ — **いいえ。** データベースは中国語「牙釘」を 0 件とし [F6]、台北市料金表にもありません [F7]。支台築造、矯正用ミニスクリュー/TAD、人工歯根のどれかを医師に尋ねてください [F3][F4][F5]。
Is “dental pin” an official name? — **No.** The Taiwan medical-device classification database returned 0 records for the Chinese query “牙釘” [F6], and the extracted full text of Taipei’s approved dental-fee schedule does not contain those two characters [F7]. It is colloquial language. The simplest next step is to ask the dentist for the formal name: post and core, orthodontic miniscrew / TAD, or dental implant [F3][F4][F5].
根管治疗后一定要打牙柱心吗？
**必须由牙医师按这颗牙评估，没有一体适用答案。** 2025 年人群证据中，整体有柱失败率较低（RR 0.61），但显著好处集中在间接修复体（RR 0.44）及纤维柱（预制 RR 0.54、可定制玻璃纤维 RR 0.66）；铸造柱心 RR 0.84、预制金属柱 RR 1.19 未达显著，整体证据为低 [F10]。这不是对个人的预测 [F25]。
根管治療後、必ず支台築造が必要ですか？ — **個々の歯を歯科医師が評価するため、一律の答えはありません。** 集団データの有意な利益は間接修復 RR 0.44、既製ファイバー RR 0.54、カスタマイズ可能グラスファイバー RR 0.66 に集中し、鋳造 RR 0.84 と既製金属 RR 1.19 は有意でなく、全体確実性は低いです [F10][F25]。
After root-canal treatment, must I always have a post and core? — **A dentist must assess your specific tooth; there is no single answer that fits everyone.** In population-level evidence, the 2025 review is stratified: overall, posts had lower failure (RR 0.61), but significant benefit was concentrated in **indirect restorations** (RR 0.44) and **fiber posts** (prefabricated RR 0.54; customizable fiberglass RR 0.66). Cast post and core (RR 0.84) and prefabricated metal posts (RR 1.19) did not reach significance; the review’s overall certainty was **low** [F10]. This is a group comparison, not an individual forecast [F25].
玻璃纤维比金属好吗？
**要先问哪一种失败。** 牙齿断裂时纤维柱相对不放柱 RR 0.15；脱粘时金属柱排序高于纤维柱（RR 0.24 对 0.39）；预制玻璃纤维柱二次龋 RR 0.40，GRADE 中等 [F12]。另一篇报告玻璃纤维 92.8%、金属 78.1%，但同时明说未达统计显著；两数**不可相减** [F13][F25]。
グラスファイバーは金属より良いですか？ — **どの失敗を問うかで変わります。** 破折、脱離、二次う蝕で結果の向きが異なります [F12]。92.8% と 78.1% は未達有意差と一緒に読む必要があり、差として減算できません [F13][F25]。
Is glass fiber better than metal? — **It depends on which “failure” you mean.** The network meta-analysis reports outcomes separately: fiber posts versus no post had lower tooth fracture (RR 0.15); for **debonding**, metal posts ranked above fiber posts (RR 0.24 versus 0.39); and prefabricated glass-fiber posts had a significant secondary-caries finding (RR 0.40), with moderate GRADE certainty [F12]. Another meta-analysis reports survival of 92.8% for glass fiber and 78.1% for metal but **also states the difference was not statistically significant** [F13]. Those figures must **not** be subtracted as a difference [F13][F25]. Material selection is a clinical decision based on the individual case [F25].
