Available bone in implant cases is particularly important. Bone availability describes the external architecture or volume of the edentulous area (area missing teeth) considered for implants.
What is the primary for dental implants treatment planning?
Historically, bone modification in the implant candidate was not a key factor. Instead, the existing bone volume was the primary factor used to develop a treatment plan. Short implants and fewer implants were used in less available bone, and long implants in greater numbers were inserted in larger bone volumes.
Today, however, treatment planning first considers the final prosthesis options. The patient force factors are then noted. The next consideration is the bone density in the sites of the implant abutments. The internal structure of bone is described regarding quality or density, which reflects a number of biomechanical properties, such as strength and factor in elasticity. The external and internal architecture of bone controls virtually every facet of the practice of implant dentistry. The density of available bone in an edentulous site is a determining factor in treatment planning, implant design, surgical approach, healing time, and initial progressive bone loading during prosthetic reconstruction.
When it comes to implant planning, a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. The strength of bone is directly related to bone density. The factor of elasticity is related to bone density. The percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone.
As a consequence, past clinical reports that did not alter the protocol of treatment related to bone density had variable survival rates. To the contrary, altering the treatment plan to compensate for soft bone types has provided similar survival rates in all bone densities. Once the prosthetic option, key implant position, and patient force factors have been determined, the bone density in the implant sites should be evaluated to modify the treatment plan.
Transforming the jaw to support implants
Patients do not always have the means to get implants immediately after losing a tooth. Some may not have access to a skilled implant dentist, while others may not be able to afford the procedure. So, when a patient finally decides he or she is ready, the jawbone may well have atrophied and has become too thin to support implants. Two procedures can overcome this limitation:
What is alveolar ridge augmentation?
To reinforce thin bone, a small piece of bone from the chin, back of the lower jaw, hip or shin is grafted to the jaw. Since the bone comes from your own body, there is far less chance of rejection if the procedure is done correctly. However, bone autogenous grafting is surgically invasive, costly and requires long recovery periods.
How does oral surgeon bone grafting?
The latest technique involves making an incision in the gum and injecting artificial bone material (similar in consistency to toothpaste) into the jaw where the tooth once existed. A large syringe is used to fill the bone cavity. After the material is fully absorbed and healing takes place, the jawbone is ready to accept dental implant procedures.
In some cases, a combination of a panoramic X-ray (a single x-ray that shows both of the patient’s jaw bones and all of their teeth) and a few periapical radiographs (the small individual x-rays most often taken in dental offices) will be satisfactory for a patient’s examination in regard to the dental implant procedure. In other cases, however, the dentist may feel that the three-dimensional imaging of a CT scan (“computed tomography”) may be required. This type of imaging provides substantially more information about the precise relationship between the objects and landmarks being examined and can provide optimal information for the dentist in determining the best course.
The surgeon must determine that there is an adequate quantity of bone in the region of the planned implant and that it is of sufficient quality. Making this determination will involve evaluating the shape of the bone (both width and height). It will also involve evaluating the bone’s density. The dentist can get a hint of this from the x-rays and CT scans that have been taken.
The bone problem can be naturally occurring, such as resorption (bone loss) that takes place in regions where teeth have been extracted. This type of defect is most common in cases where multiple teeth were removed several years previously. In other cases, a patient’s bone deficiency may be attributed to a dental condition, such as bone loss caused by advanced periodontal disease (gum disease).
Since the success of a dental implant will be greatly dependent upon the bone in which it is placed, the treating dentist may feel that it is necessary for them to perform bone grafting, so an adequate amount of bone exists for the implant to be successful.
