What this page measures: whether each outward-facing statement on this article can be supported by dental research literature. Provable and partly-supported statements carry real PubMed references; pending and contradicted ones are marked only as "examined but insufficient / counter-evidence found", with no claim of support. The analysed content itself lives on source page ↗.

斷裂面積大的則會建議以假牙來做修復，如斷裂部位有傷害到神經，則需要合併根管治療。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 斷裂面積大建議以假牙修復、斷裂傷及神經需合併根管治療等處置建議，未被evidence支持。
DNT-4187E6FE0889
斷裂面在牙齦下 ：如果牙齒斷裂面有一部分在牙齦下，要判斷牙齒留不留得住第一步通常是以牙冠牙根比來做考量。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 牙齦下斷裂、牙冠牙根比與牙齒留存判斷之關係。
DNT-BB53E6B13F54
從斷裂面下 2mm 到牙齒頂端為牙冠長度，到根尖為牙根長度，牙冠牙根長度比決定牙齒的去留。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: claim 陳述牙冠牙根長度測量方式與決定牙齒去留；evidence 為陶瓷牙冠根管開口之有限元素模擬，未涉及牙冠牙根長度比或牙齒保留決策。
DNT-15094FBD381E
如果牙冠牙根比 < 1:1，代表牙根比牙冠長，牙齒才會穩固；如果牙冠牙根比 > 1:1，代表牙冠比牙根長，可能會出現頭重腳輕的狀況，這時候就建議拔除，考慮牙橋或是植牙的治療方式。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 牙冠牙根比閾值、牙齒穩固性、拔除建議及後續治療選擇完全未被支持。
DNT-A549735B561F
這時候可以考慮以植牙或是牙橋來回復功能及美觀。
◐ Partly supported (scope noted below)
Supported scope: 植體贋復體（植牙假牙）在上顎前牙區可改善美觀外觀。
DNT-5597A52E3FC5
牙冠牙根比例對於預後的影響 正常情況下，牙冠（露出在牙齦外的部分）一定是比牙根（牙齦裡的部分）短的，這樣才不會頭重腳輕。

當牙齒斷裂，為了假牙的包覆性，會把假牙邊緣往牙根方向延伸，造成牙冠變長、牙根變短而改變牙冠牙根比，目前來說極限的比例就是 1:1，大於這個比例就表示牙冠比牙根長，容易造成根基不穩、牙齒晃動。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 牙齒斷裂時假牙邊緣向牙根延伸、牙冠牙根比極限 1:1、比例大於 1:1 造成根基不穩與牙齒晃動。
DNT-36D2BC79A653
所以斷掉的牙齒能不能留，牙冠牙根的比例是重點考量之一，如果牙根天生比別人長，就有更多機會保留這顆牙齒。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 斷牙保留與否、牙冠牙根比例、牙根長度與保留機會的關聯。
DNT-3830C6ADD224
如果牙冠牙根比沒有太糟的斷牙，通常可以搭配牙冠增長手術，來讓斷裂的齒質露出牙齦，再做假牙保護起來達到斷牙復形的目的。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 牙冠增長手術、斷裂齒質露出牙齦、以假牙保護達到斷牙復形等內容。
DNT-73B2E7E87FA4
牙冠增長術通常分為兩種： 單純手術，沒有搭配矯正 ：將牙齒周圍的軟硬組織往牙根方向降低，露出足夠的齒質來做假牙。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 牙冠增長術的兩種分類、單純手術定義，以及將軟硬組織往牙根方向降低以露出齒質做假牙的敘述。
DNT-3471B4EE7369
牙冠變長，牙根變短，該顆牙齒的牙齦線比左右兩顆牙齒低，較適合用在非美觀的區域。
◐ Partly supported (scope noted below)
Supported scope: evidence 直接支持在特定病例中，透過軟組織增量與平台轉換，追蹤期間沒有明顯牙齦萎縮且外觀可接受。
DNT-E8C2A0EAA9CC
會建議使用在美觀區，除了較美觀外，牙冠牙根比例也會比單純手術的比例好，缺點是時間較長，需要額外的矯正費用。
◐ Partly supported (scope noted below)
Supported scope: 僅支持上顎前牙區植牙贋復之美觀改善，與claim中『美觀區／美觀』部分相符。
DNT-B97D951BE9F2
+ 不一定，要看斷裂的位置與牙冠牙根比例。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 決定性 gate 未通過；不得以檢索相似度或主題重疊升為可證明。
DNT-F232A7AC3998
斷裂面在牙齦上方、或牙冠牙根比小於 1:1，通常有機會保留。
○ Pending (insufficient evidence; no claim of support)
10 candidate paper(s) examined; evidence insufficient to support this statement; still needed: 斷裂面位於牙齦上方、牙冠牙根比小於 1:1 與牙齒保留機會之關係。
DNT-C496D952E39A
+ 不一定，只有在斷裂傷害到牙神經時才需要合併根管治療，單純的樹脂填補或假牙修復不一定需要抽神經。
○ Pending (insufficient evidence; no claim of support)
