After tooth is extracted, the surrounding bone begins to shrink.  Excessive bone shrinkage may result into a thin bony ridge, which cannot accommodate implant.  Placing bone graft into the extraction socket prevents excessive bone shrinkage and preserves bone thickness.  Implants can be inserted after a healing period of 3 to 4 months.

The following diagrams are illustration of Site Preservation Procedure

Teeth are removed

Gum is pulled away from the bone.  Bone graft is placed into the extraction sockets

A resorbable membrane is placed over the bone graft

Gum is re-attached to bone with sutures

After 3-4 months of healing period, implants are placed and restored
