How Are Zygomatic Implants Different from Regular Implants?
If you are considering zygomatic implants, understanding how they differ from regular implants is important. Here is a comparison.
Zygomatic implants differ from regular implants in several key ways.
| Feature | Regular Implants | Zygomatic Implants |
|---|---|---|
| Anchor bone | Jawbone (maxilla or mandible) | Cheekbone (zygomatic bone) |
| Length | 8β16 mm | 30β55 mm |
| Placement location | Inside the jaw | Passes through the sinus into the cheekbone |
| Bone grafting needed | Often required for upper jaw with bone loss | Not needed |
| Treatment time | 3β9 months (longer with grafting) | 2β4 months |
| Anesthesia | Local with or without sedation | General anesthesia (typically) |
| Number used | 4β8 per arch | 2β4 per arch (often combined with regular implants) |
When each is used:
- Regular implants β for people with adequate jawbone
- Zygomatic implants β for people with severe upper jaw bone loss who would otherwise need extensive bone grafting
- Advantages of zygomatic implants:
- No bone grafting (saves time and cost)
- Can work even when the upper jaw has significantly shrunk
- Patients who have been told "not a candidate" become candidates
- Disadvantages:
- More complex surgery
- Requires an experienced surgeon
- General anesthesia is usually needed
- Slightly higher risk of sinus issues
