How Is Bone Grafting for Implants (GBR) Assessed? Indications, Materials and the Choice of Membrane｜證據鏈
An implant has to sit where it can support the future prosthesis and where the site will still be easy to clean. Only when the width, height or shape of the alveolar bone at that position falls short will a dentist assess options such as GBR, block bone augmentation, ridge splitting or sinus floor elevation. Whether the implant can be placed at the same time depends on whether primary stability can be achieved, on the morphology of the defect, and on whether the soft tissue can be closed safely. Choosing a material is not a matter of "the more expensive, the better". Autogenous bone, allograft, xenograft and synthetic materials each involve trade-offs in biological activity, volume stability, resorption rate, the burden of harvesting, and the sites to which the evidence applies; the barrier membrane, for its part, separates off the soft tissue and maintains space for regeneration. Genuinely rigorous planning answers first where the defect is, how much augmentation is needed and how long it has to be maintained, and only then turns to material brands.

FAQ
- Does an implant always need a bone graft?
- Not necessarily. If the planned implant position already has adequate bone volume and a suitable shape, a graft may not be needed. Whether one is required should be assessed by the dentist, putting the intra-oral examination, the imaging, the position of the final prosthesis and the space for cleaning together; it cannot be judged from how long the tooth has been missing.
- インプラントには必ず骨造成が必要ですか？ — 必ずしもそうではありません。予定するインプラント位置にすでに十分な骨量と適した形態があれば、骨造成は必要ないこともあります。必要かどうかは、口腔内診査、画像、最終的な上部構造の位置、清掃のためのスペースを合わせて歯科医師が評価すべきものであり、歯を失ってからの期間だけで判断できるものではありません。
