In the United States, more than 3 million people have dental implants to replace teeth lost to decay, gum disease, or injury. The rapid development of dental implants allows people to have white teeth instead of rotten teeth so that people can maintain a good image.
However, the existing dental implants cannot maintain a good image of the patient for life. This is because the current implants are prone to local inflammation or gum disease after being implanted in the patient’s gums, which greatly reduces the lifespan of the implants. Generally, dental implants last between 5 to 10 years, necessitating replacement thereafter. Therefore, patients have to bear the pain of tooth replacement and pay a lot of money at the same time. Dental implants are by no means cheap, especially imported ones.
Components of dental implants
What Is Dental Implant Surgery?
Dental implant surgery is a procedure in which a metal implant is implanted into the alveolar bone to replace the root of the tooth, and then a crown is fixed on it to replace the missing tooth in appearance and function. The so-called dental implants are mainly “planted” into implants.
Prior to the implant procedure, a series of examinations are required to assess the oral conditions. In addition to routine oral checks, the position, number, gap size, and occlusal relationship of missing teeth are determined. The most critical evaluation involves the available bone density and soft tissue quality, which necessitates imaging studies.
Dental implantation can be broadly divided into two stages. The first stage involves implant placement, during which osteoblasts in the alveolar bone foster steady growth between the bone and metal implants. The time taken for this process varies among individuals due to their distinct physiological differences.
Due to the different bone conditions of different people, it is necessary to modify the grooved bone according to the actual situation to ensure that the implant can grow firmly with the bone and that the stress is appropriate. Bone cement assistance or even bone grafting is sometimes required. When the bone condition permits, implant placement can be performed. Patients with favorable oral conditions may even qualify for immediate implants, allowing for implant placement immediately after tooth extraction.
About the Dental Implants
Implant metals are currently mainly titanium alloys, which have good histocompatibility and can accept MRI examinations. According to whether the abutment is buried under the soft tissue, it can be divided into submerged and non-submerged implant systems. The advantages and disadvantages of the two are different, but the current research results show that there is no difference in the effect and long-term use of the two. The surface of the implant will also undergo some special mechanical and chemical treatments to facilitate more stable osseointegration. At present, there are many types of implant systems on the market. They use different types of implant materials and unique surface treatment technologies.
Different types of implant products
The general steps of implant placement are: first trim the alveolar ridge, then use the positioning board to position, drill the hole, place the implant, place the covering abutment, and wait for the bone and the implant to grow firmly after the operation.
The second stage of the dental implant process involves fitting the restoration. The restorations, usually made of composite materials like bioceramics and cermets, can be either removable or fixed. Once the implant has properly integrated with the bone, it is topped with a crown restoration to complete the dental implant procedure.
It is worth pointing out that, for dental implantology, the above introduction is only to present the general process for science popularization, which omits many technical details, including guided bone regeneration technology, barrier membrane, and bone graft material selection, for different implants. (Column and spiral), different surgical methods, impressions, and techniques for making upper crowns are beyond the scope of this article.
Additionally, the market not only offers a plethora of implant system brands, but it also provides an important range of oral implant power systems. Some specialized surgical instruments may also be utilized during the implantation process, such as ultrasonic osteotomes, bone squeezers, bone extraction drills, and matching implantation tools.
Conclusion
It has been nearly 100 years since Wright’s heterogeneous implant was patented in the United States in 1891, and it has gradually become an important branch of stomatology. With the continuous progress of material science and new medical devices, oral implant technology is maturing. More importantly, the improvement of living standards and growing health consciousness have led to a wider acceptance of dental implants. The hope is that dental implant technology will continue to offer improved benefits to everyone.
