Dental implants are a common method of tooth restoration that can replace missing teeth, provide biting function, and improve oral aesthetics. However, when patients consider undergoing dental implantation, they are often informed by their dentists that bone grafting may be necessary. At this point, patients often have many questions about bone grafting. This article will address some common questions regarding "bone grafting".

Why is bone grafting necessary for dental implants?

The process of dental implant surgery involves placing artificial implants into the jawbone, known as the "alveolar bone", to provide support and anchor artificial crowns or bridges.

In certain cases, a patient's alveolar bone may be insufficient to support the implants.This can be due to bone resorption after tooth loss, naturally thin alveolar bone, or periodontal disease, resulting in inadequate bone quantity or density in the implant area.In such cases, bone grafting may be needed to facilitate bone growth, increase bone density and strength, and provide a more stable foundation for the implants, thereby increasing the success rate and long-term stability of the implants.

When is bone grafting performed?

Bone grafting involves using regenerative materials to promote the growth of bone cells.After bone grafting, it typically takes around three to six months or more for bone formation before dental implant surgery can be performed.(The waiting time varies depending on the individual's condition and the dentist's judgment.)

Bone grafting is generally performed in two ways. The first approach involves performing bone grafting first, waiting for a period of time, and then proceeding with dental implant surgery. The second approach involves simultaneous bone grafting during the implant surgery. In many cases, both approaches may be necessary, and the specifics are determined based on the dentist's clinical judgment to ensure the successful execution of the dental implantation.

What are the issues with skipping bone grafting and proceeding directly with dental implants?

We can liken bone grafting for dental implants to constructing a house. If the foundation of a house is not stable, the structure is prone to collapse and damage. Similarly, if artificial implants are placed in weak or inadequate alveolar bone, the failure rate of dental implants increases, and even if the implants can be inserted, they may become loose or damaged quickly. Therefore, when the condition of the alveolar bone at the implant site is not ideal, appropriate bone grafting can increase the success rate, stability, and durability of dental implants.

Do all dental implants require bone grafting?

The answer varies from person to person, as the need for bone grafting in dental implantation is a case-by-case issue.Before considering dental implants, patients should consult with a dentist for professional advice and undergo a detailed oral examination, including X-rays such as a cone beam computed tomography scan, to make a diagnosis based on the patient's bone quantity, bone quality, and implant site. This helps determine whether bone grafting is necessary and allows for the selection of the most suitable dental implant plan.

Although the entire dental implant procedure may take some time, it is the most effective and long-lasting solution for restoring missing teeth and improving oral health and quality of life.
