EXTRACTIONS AND BONE GRAFTING (ORAL SURGERY)
The most common procedures in oral surgery involve routine tooth extractions, surgical tooth extractions and bone grafting. We offer oral sedative medications or nitrous oxide gas to relieve you of your anxiety and promote a tranquil, comfortable experience. Our doctor is also on call for any post-operative emergency you might have.
Simple and surgical extractions:
At Classic Dental Care, we believe in helping our patients make the most efficient and economical choices when approaching painful or damaged teeth. Therefore if we aren’t confident that we can successfully restore a problematic tooth, then we advise to save the time and expense and have it removed for relatively little cost. The most common reasons a tooth is unrestorable can be because the decay is too extensive, tooth mobility, or fracture of the root of the tooth. In such situations it’s better to “cut your losses” and opt for a replacement tooth after extraction.
What about wisdom teeth?
Wisdom teeth, as you all know are more often problematic. The lack of space in the human jaw causes them to impact and damage the 2nd molars or cause infections of the surrounding tissues. Most often they are badly decayed due to lack of access for proper hygiene. In other instances wisdom teeth may even have cysts and benign growths associated with them. We will advise you regarding your choices after your dental exam and cleaning. Although most wisdom teeth should be extracted for better health, there are situations when they can be kept and maintained without future complications.
Dr. Zia performs bone grafting to preserve the bony ridge after tooth extraction. When a tooth is removed it leaves a large empty void (socket) in the jaw surrounded by thin walls of bone. If a bone graft isn’t placed, then the extraction site will collapse and shrink leaving a thin bony ridge about 40% smaller than the dimensions of the original bony ridge. This becomes unsuitable to support an implant, denture or bridge. Because implants and natural teeth are supported by, and embedded in bone, their strength and support depend on the bulk, strength and health of that bony tissue directly around them. You can think of each tooth like a fence post that relies on the concrete it’s rooted into for stability. It is best to have bone grafting done at the time of extraction since the existing socket can contain the graft well. Other times it is done to bulk up a narrow ridge which has emaciated from prior tooth extraction and/or infection. A collagen membrane is sutured over the graft to keep it in place as well as to prevent gingival (soft tissue) ingrowth.
What is Bone Graft Material made of?
There are four main types of material used for bone grafting:
Autogenous graft – This is the patient’s own bone that is harvested from another part of the body.
Allograft – This is human cadaver bone from a tissue bank that is sterilized and processed for use in dentistry.
Xenograft – This type of bone is harvested from another species of animal, usually a cow.
Alloplast – This is a synthetic lab-made bone graft material.
Here at Classic Dental Care we use Allograft bone due to its effectiveness and ease of use. Autogenous bone is rarely used due to its additional cost and the need for a second surgical site to harvest it. There are certain situations for which Alloplast or xenograft are also beneficial.
How it Works
Mature human living bone is constituted of 5% water, 25% organic material (collagen, proteins and cells) and 70% inorganic minerals like calcium-phosphate (hydroxyapatite). Allograft bone also contains collagen and is rich in Calcium-phosphate minerals. Because of its granular nature, it provides a scaffold structure in the empty socket of the extracted tooth. This prevents the ridge from collapsing and emaciating into a narrow short ridge (undesirable). The scaffold structure with its contents rich in minerals promotes new, living bone to form. As your blood permeates the bone graft material, it introduces the body’s own natural bone forming cells. Most of the bone graft material will be eventually absorbed by your body and replaced with new living bone. The result is a preservation of the bulk of your jawbone after tooth removal.
