All-on-4 vs All-on-6
| All-on-4 | All-on-6 | |
|---|---|---|
| Number of implants per jaw | 4 | 6 |
| Typical cost | Lower | About 20–35% higher |
| Bone grafting needed | Often avoided (tilted back implants) | Sometimes, depending on bone |
| Same-day teeth | Usually yes | Usually yes |
| Support if one implant fails | Less spare support | More spare support |
| Best suited to | Lower jaw, good-quality bone | Upper jaw, softer bone, strong biters |
Our summary
Both work well. Four implants is enough for many people, especially in the lower jaw. Six gives extra safety margin where bone is soft or bite forces are high. Your dentist's judgement based on your scan matters more than the number itself.
