FAQ

Q1:牙冠、牙套、假牙,这几个词是同一件事吗?
**不完全是。**「牙套」在多数中文语境指的是单颗牙冠(此为本站用词对照 [F14])——牙根还在、把剩余冠部齿质修磨成基座后套上的修复体 [F5][F6],国际文献统计时称为 tooth-supported single crown [F1];而「假牙」是更大的集合,包含牙齿整颗缺失后由天然牙支撑、跨过缺牙区的牙桥(文献称牙支撑多单位固定假牙),文献把单冠与多单位牙桥分开统计 [F1][F2]。这一题的完整说明由 KM-DENTAL-23(草稿已成)负责。
Q1:クラウン、かぶせ物、義歯——これらの言葉は同じものですか?**まったく同じではありません。**「かぶせ物」は多くの文脈で単冠を指します(これは当サイトの用語の対応です [F14])——歯根が残っていて、残った歯冠部の歯質を削って土台にした上からかぶせる修復装置のことであり [F5][F6]、国際的な文献では集計の際に tooth-supported single crown と呼ばれます [F1]。一方「義歯」はより大きな集合であり、歯が丸ごと欠損した後に天然歯によって支持され欠損部をまたぐブリッジ(文献では歯支持の多ユニット固定性ブリッジと呼ばれます)を含みます。文献は単冠と多ユニットブリッジを分けて集計しています [F1][F2]。この問いの完全な説明は KM-DENTAL-23(草稿あり)が担います。
Q1. Are "crown", "cap" and "denture" the same thing?**Not entirely.** In most contexts "cap" means a single crown (this is this site's terminology cross-reference [F14]) — the root is still there, and the remaining coronal tooth structure is prepared into an abutment before the restoration is fitted over it [F5][F6]; the international literature calls this a tooth-supported single crown in its statistics [F1]. "Denture", by contrast, is a larger set, taking in the bridge that spans an edentulous area supported by natural teeth once a whole tooth has been lost (the literature calls it a tooth-supported multiple-unit fixed dental prosthesis), and the literature counts single crowns and multiple-unit bridges separately [F1][F2]. The full account of this question is the responsibility of KM-DENTAL-23 (draft complete).
Q2:全瓷、全锆、烤瓷,哪一种比较好?
**现有证据不支持排成一张优劣排行榜。** 针对单冠,二矽酸锂与氧化锆类全瓷的五年存活率与金属烧瓷相当,而单层式设计的陶瓷破裂与崩瓷显著少于堆瓷式选项 [F1];同一篇也记录,长石质/矽基陶瓷、玻璃渗透氧化铝、致密烧结氧化铝与堆瓷式白榴石/二矽酸锂强化玻璃陶瓷单冠的五年存活率显著低於单层式二矽酸锂单冠,但堆瓷式致密烧结氧化锆不在该名单内 [F1]。针对多单位牙桥,二矽酸锂的五年存活率则显著低于金属烧瓷 [F2]——同一种材料在不同用途上的结论并不一致。一份检索至 2017 年 5 月的 Cochrane 系统综述并指出,就其纳入的 9 篇试验而言,不含金属材料相对于金属烧瓷的效果,现有证据不足以支持或反驳,且该批证据质量非常低 [F4]。适合哪一种因人而异,须由牙医师评估。
Q2:オールセラミック、フルジルコニア、メタルボンド——どれが良いのですか?**既存のエビデンスは優劣の順位表に並べることを支持していません。** 単冠については、二ケイ酸リチウムとジルコニア系のオールセラミックの 5 年生存率はメタルボンドと同等であり、モノリシックの設計のセラミックの破折とチッピングは前装型の選択肢より有意に少ないものでした [F1]。同じ論文はまた、長石系/シリカ系セラミック、ガラス浸透アルミナ、高密度焼結アルミナ、前装型のロイサイト/二ケイ酸リチウム強化ガラスセラミック単冠の 5 年生存率がモノリシックの二ケイ酸リチウム単冠より有意に低かったこと、ただし前装型の高密度焼結ジルコニアはその一覧には入っていないことも記録しています [F1]。多ユニットブリッジについては、二ケイ酸リチウムの 5 年生存率はメタルボンドより有意に低いものでした [F2]——同じ材料でも、用途が違えば結論は一致しません。2017 年 5 月までを検索した Cochrane のシステマティックレビューはさらに、その組み入れた 9 件の試験に関する限り、金属を含まない材料のメタルボンドに対する効果について既存のエビデンスは支持するにも否定するにも不十分であり、その一群のエビデンスの質は非常に低いと指摘しています [F4]。どれが適しているかには個人差があり、歯科医師による評価が必要です。
Q2. All-ceramic, full-zirconia, porcelain-fused-to-metal — which is better?**The existing evidence does not support arranging them into a league table.** For single crowns, lithium-disilicate and zirconia-based all-ceramic materials achieve five-year survival rates comparable to metal-ceramic, and the monolithic designs showed significantly fewer ceramic fractures and less chipping than the veneered alternatives [F1]; the same publication also records that the five-year survival rates of feldspathic/silica-based ceramic, glass-infiltrated alumina, densely sintered alumina and veneered leucite/lithium-disilicate reinforced glass-ceramic single crowns were significantly lower than that of monolithic lithium-disilicate single crowns, while veneered densely sintered zirconia is not on that list [F1]. For multiple-unit bridges, lithium disilicate has significantly lower five-year survival than metal-ceramic [F2] — the conclusions for one and the same material are not consistent across applications. A Cochrane systematic review searched to May 2017 further points out that, as regards the 9 trials it included, the existing evidence is insufficient to support or refute the effectiveness of metal-free materials relative to metal-ceramic, and that the quality of that body of evidence was very low [F4]. Which one suits a given person varies from person to person and must be assessed by a dentist.
Q3:牙桥大概能撑几年?
**文献给的是研究人群在特定时点的估计,不是个人的年限预测。** 一份纳入 41 篇研究、600 座金属烧瓷与 1,532 座全瓷牙桥的荟萃分析估计,五年存活率依材质落在 82.5% 至 92.9% 之间,而五年内未发生任何并发症的比例为 71.0% [F2]。这是人群统计值,不能推估任何一座牙桥在特定人身上的结果。
Q3:ブリッジはだいたい何年もちますか?**文献が示すのは、研究集団の特定の時点での推定値であって、個人の耐用年数の予測ではありません。** 41 件の研究、600 装置のメタルボンドと 1,532 装置のオールセラミックブリッジを組み入れたメタアナリシスの推定では、5 年生存率は材料によって 82.5% から 92.9% の間にあり、5 年以内にいかなる合併症も生じなかった割合は 71.0% でした [F2]。これは集団の統計値であり、特定の人の口の中にある特定のブリッジの結果を推し量ることはできません。
Q3. Roughly how many years will a bridge last?**What the literature gives is an estimate for a study population at a particular time point, not a prediction of the number of years for an individual.** A meta-analysis including 41 studies, 600 metal-ceramic and 1,532 all-ceramic bridges, estimates five-year survival by material as falling between 82.5% and 92.9%, with 71.0% free of any complication within five years [F2]. These are population statistics and cannot be used to estimate the outcome of any one bridge in any one person.
