Dental implants have skyrocketed in popularity lately because of dramatic improvements in achievement rates and the level of tooth function they can offer. Like most revolutionizing medical and dental advances, dental implants have a long history over which time their viability has continued to increase. Just in the last few decades has their own reliability really skyrocketed as demonstrated in clinical studies. This report outlines why the current implants are much more successful and what factors lead to success. Notice how dental implants have been placed for a synopsis of the procedure and descriptive pictures of implant components.
Early Proof of Cosmetic Dentistry – Low Success
From the 1930s, an excavation of the remains of a young Mayan woman believed to date back to approximately 600 AD, showed some of the first-known signs of dental implants. In fact, these implants were initially thought to have been placed for adornment after the young lady’s death – a clinic that was quite common in ancient Egypt. It was 1970 before a Brazilian scientist used radiography to offer evidence that the Mayan woman’s dental enhancements (made from seashells) were placed before her death. The x-rays showed that bone had regenerated approximately two of the three implants. The scarcity of artifacts that are similar indicates an extremely low success rate at that time, even though the Mayan civilization was clearly noted for its advances and achievements. Little was probably known about why these dental enhancements worked (and why others did not).
Experimentation Continued – Successes Not Well Understood
Heavy experimentation in dental implants occurred in the 19th century. Gold and platinum were the materials typically used, and implants have been frequently placed immediately after extraction. By that time, the 18th-century attempts to implant human teeth had already provided evidence that the human body would reject somebody else’s teeth. The 19th-century implants which were initially successful did not seem to last.
An Accidental 20th Century Breakthrough Provides Major Clues
The radical advances in dental implants started in the 1950s when Swedish orthopedic surgeon Dr. P.I. Brånemark was doing research on bone regeneration and recovery. He was studying the process by using optical chambers made from titanium which has been screwed into bone. After making observations for a couple of months, he found that the (expensive ) optical chambers couldn’t readily be removed for reuse because bone had formed and hardened around the screws. Brånemark branched from the”standard” field to examine the exciting consequences for implant dentistry, especially since the results (in the mouth) were more readily suited for clinical observation. (Today, of course, titanium implants are also very crucial in successful joint replacements and prosthetics.)
Brånemark and his group coined the term osseointegration to describe the successful structural and functional link between living bone tissue and an artificial load-bearing implant. While his first titanium dental implants have been successfully placed into an individual volunteer in 1965, many years of intense research followed. It was not till 1982, when Brånemark presented his scientific data to the Toronto Conference on Osseointegration in Clinical Dentistry, that a substantial turning point happened in the approval and comprehension of successes with titanium implants.

What Have We Heard Today About Success?
Today we are aware that there are many distinct factors involved in the success of dental implants and osseointegration, generally. A number of the most important variables are:
– The biocompatibility of the implant substance – Titanium is a good material not so much since the body enjoys it, but because the body does not reject it. It doesn’t tend to rust like stainless steel. Biocompatibility is both a short term and long-term thought. Research other biocompatible materials continues.
– The design or shape of the implant – Dr. Alvin Strock in 1937, working at a Harvard University laboratory, created the concept of utilizing a screw-shaped implant, which is one of the most successful design shapes and most commonly used nowadays. Additional design research persists.
– The surface of the implant – This continues to be among the very highly-researched regions to determine what coatings should serve in addition to how porous they ought to be to result in the best osseointegration and long-term outcome.
– The condition of the receiving bone tissue – Great bone health and good oral health, in general, have long been recognized as crucial factors for effective dental implants. Because of this, bone grafts and restorations often precede the augmentation process when the host tissue is not in good shape.
– The implant surgical procedure – How and when the bone and surrounding tissue is prepared to receive the implant is quite important. Excessive disturbance and damage of the bone tissue may diminish success prices. The subject of the number of phases of preparation is required so as to accomplish the greatest success is likewise the subject of recent study, concurrent with the development of one-step implant products/processes.
– The load on the augmentation – Research also continues on the effect of load (force) on the implant. The direction of this load is significant and will vary according to the position in the mouth. Detrimental load generally results in bone loss and eventual reduction of stability of the implant. All aspects of load – including whether it can/should be immediate, intermediate, or delayed for certain conditions – are still being researched in detail because of their influence on successful outcomes.
While the success rate of dental implants is high (roughly 95% based on American Association of Oral and Maxillofacial Surgeons), the success rate varies based on the tooth location where the implant is being placed. The success factors identified above don’t include other details of the individual’s general health that could affect outcomes.
For example, those who have uncontrolled diabetes and those who smoke have significantly lower achievement rates. Your provider of dental implants can help you understand the success factors for your unique scenario, including the value of dental hygiene prior to, during and after the implant procedure.
