Dental implants have revolutionized toothreplacement, offering a 95% success rate over 10 years. As thegold standard for missing teeth, implants preserve jawbone integrity whilerestoring natural function and aesthetics. Over 3 million implantprocedures are performed annually worldwide.
Implant System Components
Three-Part Structure
- Titanium Fixture (root replacement)
- Osseointegrates with jawbone
- Various lengths (8-18mm) and diameters (3-6mm)
- Abutment (connector)
- Customized for gum thickness
- Multiple angulation options
- Prosthesis (visible tooth)
- Crown (single tooth)
- Bridge (multiple teeth)
- Overdenture (full arch)
Bone Quality Classification
Lekholm & Zarb Scale
| Type | Description | Implant Success Rate |
| I | Homogenous compact bone | 98% |
| II | Thick cortical + trabecular | 95% |
| III | Thin cortical + dense trabecular | 90% |
| IV | Very thin cortical + sparse trabecular | 80% |
Advanced Techniques
Bone Augmentation Options
- Sinus Lift (for maxillary posterior)
- Ridge Expansion (narrow ridges)
- GBR (Guided Bone Regeneration)
- Block Grafts (severe atrophy)
Immediate Loading Protocols
- All-on-4®: Full arch in 24 hours
- Teeth-in-a-Day: Provisional crowns
- Requirements: Primary stability >35Ncm
Postoperative Care
Healing Phases
| Phase | Duration | Key Instructions |
| Initial | 0-72 hrs | Ice packs, soft diet |
| Osseointegration | 3-6 mos | Avoid chewing pressure |
| Prosthetic | 2 weeks | Special cleaning tools |
Success Factors
Key Determinants
- Implant Surface: Rough-textured > machined
- Surgeon Experience: >50 placements/year
- Oral Hygiene: Peri-implant care critical
- Smoking Status: 2.5x higher failure if smoking
