- Patient: 50 year old patient
- Medical history: well controlled hypertension, non smoker
- Initial situation with a high lip position (left), Intra oral view of the area (right)
- Missing tooth on #21
- Periodontal disease
- Mobility grade 3 on #11 and #12
- Extraction of #12 and #11
- Horizontal and vertical augmentation of the anterior maxilla with a GBR procedure
- Implant placement into the augmented ridge of site 11 and 12 in four months
29V_GBR_09
The site exposed by rising a trapezoidal flap

29V_GBR_10
With extraction of #11 and #12, the granulation tissue was removed.

29V_GBR_11
Frontal view of the bone defect.

29V_GBR_12
Occlusal view of the bone defect.

29V_GBR_13
Perforation of the cortical plate of the bone to allow the defect volume to be populated with new vessels.

29V_GBR_14
Tenting screw placement.

29V_GBR_15
Occlusal view of the tenting screws.

29V_GBR_16
Frontal view of the tenting screws.

29V_GBR_17
The autologous bone was harvested in the cortical of mandibular area with ACM bone collector from neobiotech, the autologous was soaked in blood and mixed with DBBM.

29V_GBR_18
DBBM and autologous bone packed into the defect around the tenting screw in a slightly over contoured fashion, a resorbable membrane was used to separate the tissue compartment made up of bone from the overlying soft tissue

29V_GBR_19
Tension free Primary wound closure.

29V_GBR_20
Second procedure after 4 months.

29V_GBR_21
Intra-operative view of the second surgical session. All the vertical and horizontal defect was resolved.

29V_GBR_22
Removing of the tenting screws.

29V_GBR_23
Drilling for implant placement.

29V_GBR_24
Occlusal view of the implants.

29V_GBR_25
End of the second stage surgery.

This case present a guided bone regeneration for horizontal and vertical augmentation prior to implant placement in the anterior maxilla.
