A 44-year-old female patient presented with missing teeth in the mandibular right posterior region (45–47).
Clinical and CBCT evaluation revealed a severe horizontal ridge defect with limited bone width and reduced vertical dimension, making implant placement impossible.

• Residual bone width: approx. 2.4mm
• Residual bone height: 9.2–9.6 mm
• Indication: horizontal ridge augmentation prior to implant placement

Surgical Procedure

A full-thickness flap was elevated and the recipient site was prepared.
Autologous bone was harvested from the retromolar region using a safe scraper.

The grafting material consisted of:

• Autologous bone
• cerabone^® +HyA (xenograft with hyaluronic acid)
• Mixed in a 1:1 ratio

A Jason^® membrane was fixed lingually using titanium pins.
The graft mixture was placed to achieve horizontal and partial vertical augmentation following the Sausage Technique .

The membrane was tensioned and stabilized, ensuring graft immobilization and space maintenance.
Tension-free primary wound closure was achieved using a combination of simple and mattress sutures.

Healing Phase

Healing was uneventful. Follow-up examinations were performed at 1, 3 and 6 months.

CBCT after 6 months demonstrated significant bone regeneration:

• Bone width increased to 7–9.2 mm
• Bone height increased to 12.6–12.8 mm
• Sufficient volume for implant placement

Implant Placement

Re-entry surgery was performed after 6 months. Two implants were placed in regions 45 and 47. Healing abutments were placed and soft tissue closure performed.

Prosthetic Restoration

After osseointegration, second-stage surgery was performed and impressions were taken.  A screw-retained implant-supported bridge was delivered.

Outcome

Stable horizontal bone regeneration was achieved, allowing prosthetically driven implant placement.
Radiographic and clinical follow-up showed stable peri-implant bone conditions.

Follow-up period: 3 years
