Bone grafts frequently asked questions: Kanata implants Carleton Place

What is the best biomaterial for bone grafts: autogenous, allograft, or xenograft bone?

Autogenous bone is an excellent bone graft material in most scenarios, with very high success rates. However, its use presents greater surgical complexity and a longer recovery time, because it creates two surgical sites, the donor site and the recipient site.

For this reason, we predominantly use allograft bone from a tissue bank, which provides highly effective results with success rates that are comparable to autogenous bone.

Synthetic grafting materials, as well as bovine xenograft, are generally indicated for grafting the maxillary sinus in sinus lift procedures.

Which graft can be used in small defects and which in large ones?

In most cases, granular allograft is used for small defects. This makes up the majority of cases seen in the dental office. In maxillary sinus surgeries, the use of xenograft is more common. In cases of major defects, it is necessary to use bone blocks that are also sourced from a tissue bank.

How much does a bone graft cost? Is it possible to estimate the price and cost of materials?

It is not possible to estimate treatment costs without conducting an accurate clinical examination, which includes complementary tests such as computed tomography, panoramic radiography, and examinations of the patient’s oral and general health.

Can I do my bone graft treatment with sedation?

Simpler cases, which make up about 95 percent of cases, can be performed in the office, but more complex cases sometimes require sedation or general anesthesia. Almost all treatments can be performed under sedation if desired, but most of the time this is unnecessary. In our practice, we have found that nitrous oxide can be an effective way to provide calm and comfort to the patient, though its use is also uncommon. Local anesthetic is usually all that is needed to provide a comfortable and pain-free experience.

What is the treatment sequence for bone grafting? Will I be without the tooth for long?

Grafting is usually performed in conjunction with the removal of a tooth. The treatment steps are:

• Digital radiographs, including computed tomography and panoramic imaging, along with treatment planning
• Removal of the compromised tooth and grafting of the site. This is followed by a waiting period for the region to heal and densify for at least 4 months. The use of a provisional prosthesis is common in cases involving removal of a front tooth. Sometimes the implant can be placed during the same surgical procedure.
• Implant placement, which typically takes place 4 to 6 months after tooth removal and graft placement
• Prosthesis or crown insertion, usually 3 to 4 months after implant placement

I have been told by my dentist that I need a maxillary sinus lift procedure performed to place an implant in my upper jaw replacing a missing tooth. What are the risks? How will I feel postoperatively?

Maxillary sinus lift surgery is not only a safe procedure, it is also a very simple, routine, and fast-healing one. This often comes as a surprise to people when they hear the words sinus lift. Depending on how low the sinus floor has descended toward the roots of the upper teeth, the patient will have a certain amount of bone available to place a standard implant. Sometimes shorter implants can be placed. Other times, the only option is to perform a sinus lift together with implant placement.

One of the few downsides to sinus lifting is perforation of the very thin membrane of the maxillary sinus. It is rare for this to happen. The advantage of this tissue is that it heals extremely quickly, so even if a tear occurs, the procedure can often be attempted again after a short period of time. The postoperative period is usually very short, and in the majority of cases there is little to no pain or swelling.

If it is well indicated, then it should be done, as it is one of the best ways to obtain rehabilitation of the posterior area of the maxilla, or upper jaw. If you have any questions about grafts or dental implants, contact us through one of the channels below or schedule an appointment.
