FAQ

The survival rate of all-ceramic crowns looks highest. Should I simply have an all-ceramic crown?

That inference is not advisable. In the same meta-analysis, the 96% survival rate for single crowns corresponded to a mean follow-up of **4.6 years**, while 90% for partial-coverage restorations corresponded to **6.2 years** and 90.2% for veneers to **6.5 years** [F1]. Figures with different follow-up periods cannot be compared side by side. These restorations were also used for different extents of defects, rather than being tested in a randomised head-to-head trial [F1].

オールセラミッククラウンの生存率が最も高く見えます。最初からオールセラミッククラウンにすべきですか？ — そのような推論は勧められません。同じメタアナリシスで、単冠の生存率 96%に対応する平均追跡期間は**4.6年**でしたが、部分被覆修復物の 90%は**6.2年**、ラミネートベニアの 90.2%は**6.5年**でした [F1]。追跡期間が異なるため、数値を直接並べて比較することはできません。また、これらの修復物はもともと異なる欠損範囲に用いられており、ランダム割付による直接比較試験ではありません [F1]。
