Is bone grafting always necessary when there is insufficient bone for an implant? Choosing grafting, a different implant size or another treatment｜證據鏈
Insufficient bone does not mean that every patient must follow the same grafting process. Current systematic reviews indicate that lateral bone augmentation can increase bone width and make subsequent implant placement feasible. In selected posterior conditions, however, short implants may reduce the need for vertical augmentation, while narrow-diameter implants may be assessed in some anterior cases. These approaches are not shortcuts that can be interchanged freely. Each body of research is limited to particular defect directions, sites and case conditions. If the surgical burden or restorative conditions of an implant route are unsuitable, a tooth-supported fixed bridge can also be discussed as a separate treatment route. The central comparison is which route can accommodate implant or abutment position, prosthetic design, risk and subsequent maintenance in your circumstances.

FAQ
- If the dentist says there is not enough bone, must it be grafted?
- Not necessarily. Lateral grafting can increase width, but short implants may be compared in selected posterior cases and narrow-diameter implants assessed in some anterior-maxillary cases [F1][F4][F3]. Whether they can substitute depends on whether the defect and site fit the evidence.
- 骨が足りないと言われたら、必ず骨造成が必要ですか？ — 必ずしもそうではありません。水平的造成は骨幅を増やせますが、特定の臼歯部ではショートインプラント、一部の上顎前歯部では狭径インプラントが検討される場合があります [F1][F4][F3]。代替できるかは欠損と部位が研究範囲に合うかで決まります。
