When Did Dental Implants First Start?
The desire to replace missing teeth is not a modern phenomenon. It is a fundamental human aspiration that stretches back thousands of years. When we ask, “When did dental implants first start?” the answer takes us on a fascinating journey through history. It is a story of trial and error, of ancient ingenuity, and of a modern scientific breakthrough that changed dentistry forever. This guide will trace the timeline of dental implants, from the earliest known attempts to the sophisticated technology of today.
The Ancient World: The First Attempts (2000 BC – 600 AD)
The earliest evidence of humans trying to replace missing teeth comes from ancient civilizations. These attempts were rudimentary, but they demonstrate a deep-seated desire to restore function and appearance.
1. Ancient China (Around 2000 BC)
The oldest known evidence of dental implants comes from ancient China. Archaeologists have found remains with bamboo pegs carved and tapped into the jawbone to replace missing teeth. Bamboo was a readily available and easily shaped material. While these implants were unlikely to have been very successful, they represent the first recorded attempt at creating an artificial tooth root.
2. Ancient Egypt (Around 1000 BC)
The ancient Egyptians practiced a form of tooth replacement. Mummies have been discovered with teeth held in place by gold wire. In some cases, these were the deceased’s own teeth, reinserted into the jaw. In other cases, they were teeth from donors (sometimes slaves). It is debated whether these were placed during life for function or after death for burial rituals. Regardless, they show an understanding of the value of a complete set of teeth.
3. The Mayan Civilization (Around 600 AD)
This is one of the most remarkable discoveries in the history of implant dentistry. In 1931, while excavating a site in Honduras, archaeologists found a fragment of a Mayan mandible (lower jaw). The jawbone belonged to a young woman who had died around 600 AD. She had three missing incisor teeth. In their place were pieces of shell, carefully shaped to resemble teeth.
What made this discovery extraordinary was revealed by X-rays. The bone had grown around the shell fragments. Compact bone had formed around the implants, suggesting they had been placed during life and had integrated with the bone. This is a rudimentary example of what we now call osseointegration. It happened 1,400 years before the term was even coined.
4. Ancient Rome and Medieval Europe
Historical texts describe attempts to replace teeth using various materials. Iron, gold, and even teeth extracted from animals or cadavers were tried. These attempts were almost universally unsuccessful. The materials were rejected by the body, or infections developed. The lack of sterile technique and the understanding of biocompatibility meant these early implants were doomed to fail.
The Early Modern Era: Experimentation and Failure (1800s – 1950s)
The 19th and early 20th centuries saw a flurry of experimentation. Dentists and physicians were trying to find a material and a technique that would work.
1. Gold and Platinum Implants (1800s)
Some dentists attempted to place implants made of gold or platinum. These metals are relatively inert, but they are soft and did not integrate well with bone. The implants would often become loose and fall out.
2. The Vitallium Breakthrough (1930s)
A significant step forward came with the development of a new metal alloy called Vitallium (a cobalt-chromium-molybdenum alloy). It was strong, corrosion-resistant, and well-tolerated by the body. In 1937, Dr. Alvin Strock and his brother Dr. Moses Strock used Vitallium to create an implant post. They placed it into the jawbone of a patient. This was one of the first successful endosseous (within the bone) implants of the modern era. It proved that a metal implant could be accepted by the body.
3. The Subperiosteal Implant (1940s-1950s)
Dr. Gustav Dahl in Sweden developed the subperiosteal implant. This was a metal framework that was placed on top of the jawbone, underneath the gum tissue. Posts extended through the gum to hold a denture. This was designed for patients with severe bone loss who could not wear conventional dentures. It was a popular treatment for a time, but it had a high long-term failure rate.
4. The Blade Implant (1960s)
Dr. Leonard Linkow, an American dentist, developed the blade implant. This was a flat, blade-shaped piece of titanium that was inserted into a groove cut into the bone. It was a major improvement over previous designs and was used widely for several decades. However, it was not a true root replacement and was prone to failure over time.
The Modern Era: The Discovery of Osseointegration (1950s – Present)
The true turning point in the history of dental implants came from an accidental discovery in a laboratory in Sweden.
1. Per-Ingvar Brånemark and the Rabbit Experiment (1952)
Dr. Per-Ingvar Brånemark was a Swedish orthopedic surgeon studying blood flow in bone. He inserted small titanium cylinders into the leg bones of rabbits. When he tried to remove the cylinders later, he found they were stuck. The bone had grown directly onto the titanium surface. He called this phenomenon “osseointegration.”
Brånemark recognized the enormous potential of this discovery. He realized that titanium was unique. The body did not reject it. Instead, it accepted it as if it were its own tissue.
2. The First Human Implant (1965)
Brånemark spent years refining his techniques. In 1965, he placed the first titanium dental implant in a human volunteer named Gösta Larsson. Larsson had severe jaw deformities and missing teeth. He received four implants to support a full bridge. The implants were successful. Larsson lived with them for over 40 years.
3. The Toronto Conference (1982)
Brånemark faced significant skepticism from the dental community for years. They did not believe metal could truly fuse with bone. The turning point came in 1982 at the Toronto Conference on Osseointegration in Clinical Dentistry. Brånemark presented his decades of research. The evidence was overwhelming. The dental world finally embraced the concept of osseointegration.
4. The Commercial Era (1980s – Present)
Brånemark partnered with a Swedish company to develop his implant system. The company, later named Nobel Biocare, brought the first commercial titanium implants to market in the 1980s. Since then, the field has exploded. Dozens of companies now manufacture implants. The designs have evolved significantly, with improved surfaces, thread patterns, and connection types.
5. The Rise of Zirconia (2000s – Present)
While titanium remains the gold standard, ceramic (zirconia) implants have emerged as a metal-free alternative. Zirconia is white, biocompatible, and offers excellent aesthetics. It is a newer option but is gaining popularity.

Important Notes for Readers
- The Principle Matters More Than the Date: While the dates are interesting, the key takeaway is the discovery of osseointegration. This principle is the foundation of all modern implant dentistry.
- The Evolution Is Ongoing: The dental implant is not a static device. It continues to evolve. New materials, new surfaces, and new digital techniques are constantly being developed.
- Choose a Proven System: When getting an implant, choose a reputable brand with a long track record. The success of your implant depends on the quality of the engineering and the research behind it.
The Bottom Line
Dental implants first started thousands of years ago, with ancient civilizations using bamboo, shells, and metal to replace missing teeth. However, the modern era of successful implants began with Per-Ingvar Brånemark’s accidental discovery of osseointegration in 1952. His first human implant in 1965 marked a turning point. Today, dental implants are one of the most successful and predictable procedures in all of medicine, a direct result of this long and fascinating history.
Frequently Asked Questions (FAQ)
Q: Were the Mayan shell implants successful?
A: The evidence suggests they were tolerated by the body. X-rays showed bone had grown around the shells. They may not have been functional for chewing, but they did not cause problems.
Q: Why did early metal implants fail?
A: The metals used (iron, gold, platinum) were either not strong enough, not biocompatible, or the surgical techniques were not sterile. Infection and rejection were common.
Q: Is titanium the only material used for implants today?
A: No. Titanium is the most common and has the longest track record. Zirconia (a type of ceramic) is a metal-free alternative that is gaining popularity.
Q: How has the design of implants changed since Brånemark’s time?
A: The original implants were machined titanium screws with a smooth surface. Modern implants have roughened surfaces that promote faster bone healing, improved thread designs, and internal connections that are more stable.
