|3 D ridge augmentation using mesh|
Take a close at the 3 D deficiency at ant maxilla.
What is your tx. plan for ridge augmentation ?
1) Autologous iliac bone is indicated but too much traumatic to patient and eraly bone resorption of iliac bone can be aboided
2) Chin bone graft. It' too small bone block to cover this defect.
3) BMP/ alllograft/ Mesh. BMP is too mch expensive and develops postop swelling.
4) My choice is autologous concentrated growth factor / Allograft / Bovine / Mesh.,
Allograft induces fast bone reformation.
Bovine bone prevents bone resorption.
Autologous growth factors accelerated new bone formation and soft tissue healing.
Mesh is a excellent space maker.
More than 10mm vertical deficiency is seen,
Implants were placed simultaneously. However implant placement can be delayed.
CGF was prepared before surgert.
The mixture of bone subtitutes/ CGF was placed on the defect.
Overgrafting is necessary.
Mesh was stabilized with mini screw.
To accelerate soft tissue healing, CGF membrane was placed on the mesh.
Tension free suture is strongly required.
6 M healing was allowed. Look at the excellent ridge augmentation.
CT scnas after augmentation,
