Bone Grafting and Sinus Lifts in Dallas
Skilled regeneration of lost bone
Drs. Ovadia and Tanur provide expert bone grafting treatment to help prevent bone loss in the jaw and in some cases when preparing a missing tooth for a dental implant replacement.
Your teeth are anchored in bone that forms the upper and lower jaws. Strong ligaments and supporting bone under the teeth keep them firmly held in position.
The supporting bone can be lost for a variety of reasons and the teeth can be weakened and eventually lost. But lost bone can be regenerated and your teeth and jaw preserved using bone grafting.
Expert bone grafting specialists
As periodontists, Dr. Tanur and Dr. Ovadia are both highly trained and skilled in bone grafting procedures to restore lost bone. Both doctors are also board-certified periodontists, a status earned by only 10% of periodontists. Board certification occurs after passing a thorough and rigorous examination on all periodontal theory and procedures.
What causes bone loss?
The primary causes of bone loss around the teeth are as follows:
- Gum disease – bacterial plaque and calculus destroy the ligament and bone tissue surrounding the teeth. As the disease progresses in severity, the bone loss worsens until it cannot support the affected teeth. This eventually causes teeth to be lost.
- A missing tooth – the bone in your jaw needs stimulation from chewing and biting to maintain its proper density and volume around your teeth. When a tooth is missing, no stimulation occurs and the bone gradually dissolves away.
- A misaligned tooth – a misaligned tooth can act much like a lost tooth, as it can be positioned so it does not make contact with the tooth on the opposing arch when you bite. This lack of contact generates no real biting pressure and the bone surrounding the tooth will dissolve away.
- Injury to the tooth – tooth injury or trauma can cause the tooth to shift or become infected. The infection spreads and causes bone loss around the tooth.
- Infection in the jaw – an infection other than gum disease can get into the bone tissue surrounding your teeth and causes bone loss. This includes bacterial or viral infections, and tumors.
Dentures and bone loss
Dentures do not provide the stimulation necessary to maintain bone volume after you lose your teeth. The pressure on your jaw exerted by dentures actually accelerates the rate of bone loss and wears away the ridges of bone they are placed on. The size and height of your jaw shrinks as the alveolar ridge wears away.
This accounts for the continual need to refit the denture, sore spots and difficult or painful chewing. It also accounts for the gradual collapse of the bottom third of your face after you have lost all your teeth and no longer have the stimulation to keep the bone volume maintained.
Missing teeth and wearing dentures cause the jaw to shrink and the lower third of your face to eventually collapse.
Bone grafting replaces lost bone
Bone grafting is a frequent element of periodontal surgical procedures. The essence of bone grafting is to replace lost bone by placing biocompatible bone material into the space where the bone is missing. The graft material itself does not actually become the new bone. It stimulates the growth of fresh bone tissue to fill up the space where the bone graft material is placed. The bone graft material harmlessly dissolves away into the bloodstream.
Bone graft material can be obtained from bone in other parts of the body, from a human tissue bank, or from other biocompatible material that simulates regeneration of new bone.
Advanced dental technology for efficient grafting
Dr. Ovadia and Dr. Tanur use advanced materials and processes to make their bone grafting minimally invasive, highly efficient and have faster healing times.
Cone beam 3D CT scanner for precise bone grafting
When needed, the doctor will use our cone beam 3D CT scanner to get a precise view of the area in need of bone grafting. The CT scanner creates a 360° 3D image of your entire jaw which can be viewed from any angle and magnified to show small areas. The image shows the density and amount of bone surrounding your teeth.
From these images the doctor can plan the bone grafting ahead of the procedure.
Using our cone beam 3D CT scanner, the doctor can see the amount and density of the bone at every point in your jaw.
Growth proteins accelerate healing
When needed, the doctor will add growth proteins to the graft site with a PRF (platelet rich fibrins) treatment. These growth proteins accelerate bone regeneration and prevent swelling and infection.
When bone grafting is needed for implants
The doctor will place a bone graft to regenerate bone needed for tooth support, to build back the size and shape of the ridge supporting the teeth and to support the placement of dental implants.
Preserving a tooth
A tooth can have bone loss around it that compromises its stability and could lead to tooth loss if the lost bone is not regenerated. The doctor will graft bone material into the area of deficiency and rebuild proper tooth support.
Ridge preservation after tooth extraction
After a tooth is extracted, bone loss will occur where the tooth used to be and cause the space where the tooth was lost to sink. The bone loss can also cause adjacent teeth to lose bone and even shift position. This sinking can occur under a dental bridge and cause an unsightly hole under the bridge.
The doctor will place a bone graft at the site of the lost tooth and build back the alveolar ridge. The regenerated bone preserves the stability and density of the ridge between the adjacent teeth, and prepares the tooth loss site for a dental implant at the same time. A regenerated ridge under a dental bridge also enhances the aesthetics of the bridge.
Supporting a dental implant
In order to securely place a dental implant, the implant must be supported by adequate bone structure. The doctor will place a bone graft at the implant site to regenerate the bone needed for the implant to be strongly anchored.
Lifting expanded sinuses
You have a sinus cavity above your upper dental arch on each side of your face. When you lose teeth in your upper arch, particularly your upper molars, the bone loss occurs in the alveolar ridge and in the floor of the sinus cavity simultaneously. This leaves the bone too shallow to support a dental implant.
In the case where a collapsed sinus floor makes the bone too shallow for implant placement, Dr. Tanur or Dr. Ovadia will build back the depth of the supporting bone using a bone grafting procedure known as a sinus lift.
The bone under the sinus floor deteriorates after tooth loss in the upper arch.
A bone graft is placed under the sinus floor membrane and regenerates the bone needed for an implant.
Where the sinus has collapsed into the space of a single tooth and the depth just needs slight augmentation, the doctor will tap the graft material up into the socket space of the missing tooth and add bone depth adequate for an implant. The added bone will form a slight elevation in the sinus floor.
Where the bone is very shallow, the bone graft will be placed by lifting the bottom membrane of the sinus and inserting the graft material under the membrane. This raises the floor level of the sinus and makes the bone deep enough for implants to be placed securely.
