Dental Implants & Regeneration

• Implants: Osseointegrated implants are reliable for tooth replacement, with long-term success rates of 85–90% over 10 years. Success depends on patient health, implant site, and ongoing maintenance.

• Biological Risks: Main complications are peri-implant mucositis and peri-implantitis. Prevention requires careful surgical/restorative techniques, good soft-tissue (keratinized mucosa) management, and regular supportive care.

• Bone & Tissue Regeneration:

  • Guided Bone Regeneration (GBR) and Guided Tissue Regeneration (GTR) use barrier membranes (resorbable like collagen, or non-resorbable like PTFE) to block soft tissue and allow bone/periodontal cells to regrow.

  • These techniques help in ridge augmentation (horizontal/vertical) and repairing defects around implants.

  • Bone substitutes may include xenografts, allografts, or alloplasts; soft-tissue substitutes can also be used.

• Decision Factors: Success depends on defect shape, need for space maintenance, and patient risk factors (e.g., smoking, poor blood sugar control). Managing complications (like flap design and membrane exposure) is key.
