Case Study: Full-Mouth “Dual All-on-6 Dental Implants” with Sinus Lifts & Bone Grafts

Case Study Full-Mouth Dual All-on-6 Dental Implants with Sinus Lifts & Bone Grafts

Many patients who need a full-mouth restoration are told they aren’t candidates for dental implants due to severe bone loss. At Smile Dental Turkey, our expert surgeons, like Dr. Özkan Özkaynak, handle these complex cases every day.

This is the story of Frederick M., who came to us with few remaining teeth and significant bone loss in his upper jaw. His transformation required a “Dual All-on-6” procedure (All-on-6 for both jaws) and advanced surgical work to rebuild his foundation.

  • Patient: Frederick M.
  • Lead Surgeon: Özkan Özkaynak, D.D.S., Ph.D. (Surgical Phase)
  • Prosthodontist: Uğur Gültekinler, D.D.S. (Restorative Phase)
  • Procedure: Dual All-on-6 Dental Implants (Upper & Lower), 2x Sinus Lifts, 2x Bone Grafts, 6 Extractions
  • Total Investment: £7,630.00
  • Total Time: 11 Months (3 Visits)

The Initial Consultation: The Challenge of Severe Bone Loss

When Frederick M. first visited us in February 2022, he was in a difficult situation. His “Before” photo and initial X-rays showed that his few remaining teeth were failing and that he had significant bone loss, especially in his upper jaw where the maxillary sinuses had expanded.

To get a perfect view of the bone, Dr. Özkaynak ordered a 3D CBCT scan. This scan confirmed we would need to surgically rebuild the bone to create a stable foundation.

A Phased Surgical & Restorative Plan

For a case this complex, a multi-phase approach is essential for a successful, long-term outcome.

Phase 1 (February 2022): The Surgical Foundation

This first visit was dedicated to expert-level surgery.

  • 6 Tooth Extractions: Dr. Özkaynak began by removing the 6 remaining failing teeth.
  • Bilateral Sinus Lift & Bone Graft: This is the most critical step. Dr. Özkaynak performed a bilateral sinus lift (lifting the sinus membrane on both sides) and placed 2 bone grafts. This procedure rebuilds the lost bone height, creating a strong new foundation for the upper dental implants.
  • Temporary Denture: To ensure Frederick M. could eat and smile during healing, Dr. Uğur Gültekinler fitted him with a temporary denture.

Healing Phase OPG (X-ray) from July 2022: This scan shows the patient is now toothless, and the grafted bone in the upper sinuses is healing and integrating.

Phase 2 (July 2022): Dental Implant Placement

After 5 months of healing, Frederick M. returned. The grafted bone was now strong and integrated.

  • Dual All-on-6 Placement: Dr. Özkaynak placed 6 Neodent (Straumann Group) dental implants in the newly rebuilt upper jaw and 6 Neodent dental implants in the strong lower jaw. This “Dual All-on-6” system provides incredible stability for a full-mouth restoration.

Post-Surgical OPG (X-ray) from Aug 2022: All 12 dental implants are now in place, 6 in the upper jaw (anchored in the new bone) and 6 in the lower jaw.

Phase 3 (January 2023): The Final Restoration

After a final 6-month healing period for the dental implants to fuse with the bone (osseointegration), Frederick M. returned for his new smile.

  • Final Dental Bridges: Dr. Uğur Gültekinler took over the restorative phase. He took final impressions and designed two 12-unit, full-arch dental bridges (totaling 24 metal-porcelain dental crowns).
  • Final Fit: These dental bridges were permanently attached to the 12 dental implants, giving Frederick M. a complete, strong, and beautiful new set of teeth.

Final OPG (X-ray) from Jan 2023: This final scan shows the two full-arch dental bridges securely fixed to the 12 integrated dental implants. A perfect result.

The Result: A Life-Changing, Confident Smile

This case perfectly demonstrates that even with severe bone loss, a permanent, beautiful smile is possible with the right surgical team.

A Note from Özkan Özkaynak, D.D.S., Ph.D.

Frederick M.’s case is the perfect example of how we can solve severe bone loss. By performing a bilateral sinus lift and bone graft, we created the foundation that wasn’t there. This ‘expert-level’ surgical step is what made his All-on-6 restoration possible. It proves that with the right planning, almost everyone can have a permanent, fixed smile.”
