Dental Implants Ottawa
Dental Implants have become the standard of care for replacement of a missing tooth or teeth. The increased popularity of dental implants is the result of the benefits over traditional tooth replacement methods.
Computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, or flat panel CT) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.
Dental Implant Questions
Dental Implants Ottawa
At Capital Periodontics in Ottawa, we specialize in the placement of dental implants. Dental implants are essentially artificial tooth roots. They can replace a single missing tooth, multiple missing teeth, support a denture or restore an entire mouth. Dental implants are made of primarily titanium. Titanium, unlike other metals, is not rejected by the body. Titanium is very strong and is biologically inert.
At the consultation appointment, we will assess the health of the gums and remaining teeth. The periodontist will assess whether dental implants are the right choice for you. At this appointment, we will also discuss your overall oral health. The periodontist will also discuss treatment options and treatment recommendations, including the risks and benefits of dental implants. We will make sure all your questions are answered.
What is Bone Grafting?
Adequate bone volume must be present in the area of the missing teeth in order to support the future implant. Following tooth loss, the patient’s bone and gums in the area of the missing tooth tend to shrink. In cases where there is not enough remaining bone to support a dental implant an additional procedure may be needed. This procedure is called bone grafting which is performed to rebuild the bone. This can be done as a separate procedure, or simultaneously with the placement of the dental implant.
What is a Sinus Lift?
Sinus lift surgery can help increase bone levels by raising the sinus floor and developing bone for the placement of dental implants. Several techniques can be used to raise the sinus and allow for new bone to form. In one common technique, an incision is made to expose the bone. Then a small circle is cut into the bone. This bony piece is lifted into the sinus cavity, much like a trap door, and the space underneath is filled with bone graft material. Your periodontist can explain your options for graft materials, which can regenerate lost bone and tissue.
Finally, the incision is closed and healing is allowed to take place. Depending on your individual needs, the bone usually will be allowed to develop for about four to twelve months before implants can be placed. After the implants are placed, an additional healing period is required. In some cases, the implant can be placed at the same time the sinus is augmented.
Undergoing sinus lift surgery has been shown to greatly increase your chances for successful implants that can last for years to come. Many patients experience minimal discomfort during this procedure.
What Can I Expect?
Following the placement of a dental implant, the implant must be allowed to fuse with the jaw bone for a period of 3 to 6 months. Once the implant has fused to the bone, the final restoration can be connected to the implant. Temporary tooth replacement can be made for the healing period, sometimes using the implant while it is healing. Therefore, you will never have to be without teeth during the process.
The placement of dental implants is typically a minor oral surgical procedure. It is very well tolerated by patients when performed by a properly trained dental specialist. A significant portion of the graduate training program in periodontology is devoted to bone grafting and dental implants. Because it is so well tolerated, in most cases dental implant surgery can be performed with only local anesthetics. Sedation is always available for anxious patients. Implants have been around for over 40 years, and the technology is constantly improving, providing faster healing times and better aesthetic results. An implant’s greatest advantage over conventional bridges, is that the adjacent teeth don’t need to be shaved to support a replacement for the missing tooth.
Dental Implants Before And After:
What is the cost of a Dental Implant?
During your consultation appointment, you will be given a full treatment plan with the associated costs of treatment at each stage. Without the consultation, it is impossible to provide the full price of the dental implant because the cost of the implant will depend upon the type of treatment required. A straight forward implant, with adequate bone, would be less expensive than an implant and bone grafting procedure. In addition, more complex cases may require a CT (Cone Beam Technology) or a surgical guide which affects the cost of the dental implant as well.
Why see a Periodontist/Dental Implant Specialist?
All periodontists are Board Certified Specialist. To become a periodontist, one must spend three years of full time residency at an accredited university program (this is after completing dental school). During that time, a significant portion is dedicated to implant dentistry both at a theoretical and practical level. This level of training cannot be compared to weekend courses offered to dentists. Studies have shown that dental implant failure and complications are related to the level of experience of the implant surgeon and restoring dentist. A large portion of periodontal practice is dedicated to all aspects of dental implants, resulting in significant gain in experience which translate to higher success rates with fewer complications. The success rate of dental implants in our practice is over 99%.
Dental Implants – Benefits
After living with dentures or without natural teeth, people have called dental implants “life changing”. Dental implants replace the root of your tooth and fuse with your bone. Once the crown is put on (implant restored), for most patients, it feels like a natural tooth. Dental implants have many benefits. Without the root structure of a natural tooth present, the jawbone will shrink. Dental implants help maintain bone.
Since the dental implant is most like natural teeth, it looks better, and is more comfortable that dentures. The dental implant is stable and comfortable. With poor fitting dentures, speech can be affected, and eating may be uncomfortable. Dental bridges are another permanent option for tooth replacement, however, they rely on the adjacent teeth. The adjacent teeth need to be shaved, which compromise them, and may result in root canal treatment. In addition, bridges are more difficult to maintain since several teeth are connected, making it difficult to clean between the teeth.
Properly placed and restored dental implants should outlast dentures and bridges.
Dental Implants – All on 4
The “All on 4” technique refers to restoring an entire arch by anchoring a bridge on only 4 dental implants. An arch consists of all the on the upper or lower jaw. Often the all on 4 method is offered to patients who still have their natural teeth, which means the teeth must be removed prior to placing the dental implants. There has to be a very strong reason for removing teeth, and in some cases we encourage patient to save some of teeth and pursue other treatment options which may include dental implants but is less costly.
While the “All on 4” technique has been around for many years, long term studies are still lacking. We prefer the term “All on X”, where X can be any number from 2 to 8. We believe in customizing our proposed treatment to the individual patient. Some patients place more stress on their teeth and 4 dental implants will not be sufficient to support their teeth, while others are quite content with traditional dentures and require only 2 dental implants to help stabilize their dentures. We are happy to review with you all your treatment options at your consultation appointment.
Dental Implants – Cone Beam Technology (CT)
Dental cone beam computed tomography (CT) is a special type of x-ray equipment used when regular dental or facial x-rays are not sufficient. Your doctor may use this technology to produce three dimensional (3-D) images of your teeth, nerve pathways and bone in a single scan.
Cone beam CT provides detailed images of the bone and is performed to evaluate diseases of the jaw, dentition, bony structures of the face, nasal cavity and sinuses. Cone beam CT has the advantage of lower radiation exposure compared to conventional CT.
How should I prepare?
A cone beam CT examination requires no special preparation.
Prior to the examination, you may be asked to remove anything that may interfere with the imaging, including metal objects, such as jewelry, eyeglasses, hairpins and hearing aids. Although removable dental work may need to be removed, it is advisable to bring these to your examination, as your periodontist may need to examine these as well.
Women should always inform us if there is any possibility that they are pregnant. See the Safety page for more information about pregnancy and x-rays.
Dental Implants – Guided Surgery
In order to make a surgical technique simple and predictable, 3D information from tomography or computerized tomography (CT) scans is teamed with a software that provides us with a virtual model of the jaw. This helps in virtual planning and generation of a surgical guide, which in turn aids in the placement of implants into ideal positions based on the local topography and final prosthetic outcome.
Computer guided implant surgery uses cutting-edge technology to aid in the planning and surgical placement of your dental implants.
Your periodontist will take Cone-Beam CT Scan x-ray of your jawbone for guidance in treatment planning. This information allows for a 3D model of your jawbone, complete with custom digital teeth, to be generated. Virtual reality software is then used to plan the implant surgery with great accuracy and fabricate a precise surgical guide to be used during the surgery. The results are a more accurate implant placement, and less surgery time for you.
