Bone Graft and Dental Implants:
Simple bone reconstruction to prepare for dental implants
When natural teeth are ｀pulled out¨ there often occurs a period of rapid bone
loss in the area where the tooth (or teeth) have been removed. Thus, if one is
considering placing dental implants to replace the lost tooth, then there may be
insufficient bone to act as the housing for the implant. This situation is
readily remedied by the use of bone substitutes. Bone substitutes act as a
matrix for the formation of new bone. In other words, natural bone grows around
the substitute and in-between the substitute.
The body then eats away at any remaining substitute and replaces
it with natural bone. The final result is natural solid bone with no trace of
the bone substitute remaining. This process takes about six months to complete.
Often, bone substitute is placed at the same time as a dental implant. In some
cases, the substitute is placed when a natural tooth is removed and left to heal
prior to placing a dental implant.
Bone substitute is commonly available as either a wholly synthetic material or a
bovine derived material. The choice of material is discussed with you prior to
surgery. The placing of bone substitutes is safe and discussed with you in depth
prior to its usage.
Ridge Preservation for Optimum
The primary goal of any ridge preservation technique should be to preserve both
the hard and soft tissues, especially the interdental papillae, in such a way as
to optimize aesthetics and function.
Whenever there is an aesthetic concern, the blood supply and the natural
soft-tissue anatomy at the edentulous site should be preserved. Ultimately, the
avoidance of post-extraction bone resorption and the preservation of the natural
soft-tissue anatomy at the endentulous site become the key elements to obtaining
an optimal aesthetic rehabilitation at the site.
The Bio-Col Socket Preservation Technique
With an understanding of these goals and biological considerations, the
"Bio-Col" socket preservation technique was developed. The surgical protocol
ensures the preservation of both hard and soft tissues at the time of tooth
extraction, and it virtually eliminates the bone resorption that would normally
follow tooth removal.
Compromised Extraction Socket With Buccal Wall Defect. After
extraction, socket presents with a large buccal wall bone defect. Note the
partial soft-tissue collapse into the defect area.
Compromised Extraction Socket in Preparation for Delayed Implant Placement or
Conventional Prosthesis. After tooth removal, Bio-Gide∝ resorbable collagen
membrane placed in prepared subperiosteal pocket, covering bony socket wall
defect. Bio-Oss∝ bone mineral placed into the socket and defect area. Note that
Bio-Oss∝ slightly expands the adjacent Bio-Gide∝ membrane and overlying soft
CollaPlug∝ absorbable dressing is placed over the Bio-Oss∝ graft and
maintained with suture.
Technique With Immediate Implant Placement. Immediate implant placed into intact
bony socket. Bio-Oss∝ bone mineral grafted between implant and bony socket
walls. Implant fixture and Bio-Oss∝ graft covered with CollaPlug∝ absorbable
collagen dressing. Horizontal mattress suture placed to maintain position of
collagen wound dressing.
Sinus Lift Surgery
Bone loss frequently occurs around the upper molars (1) due to periodontal disease. When these teeth are removed, often
times inadequate bone is available to place dental implants in the upper
This is when sinus lift surgery can help. This procedure
raises (2) the floor of the sinus upward. Thus providing more bone
