What Patients Should Know About Dental Implants

What an implant is

A dental implant is not a tooth. It is a replacement root — a small threaded post, usually titanium or zirconia, placed into the jawbone where a tooth is missing. Over the following months, bone grows into direct contact with its surface, a process called osseointegration. Only once that has occurred can the post reliably support a restoration.

That healing period is why implant treatment is measured in months rather than appointments, and why the timeline is not something a dentist can compress at will.

The three components

Most implant restorations have three parts, and it helps to know which is which when discussing costs or repairs.

• The fixture — the post placed in the bone
• The abutment — the connector that projects through the gum
• The restoration — the crown, bridge or denture attachment that is visible in the mouth

The general sequence

A typical course begins with assessment: examination, radiographs and often a three-dimensional scan to evaluate bone volume and the position of nerves and sinuses. If a tooth still needs removal, or if bone or gum grafting is required, those steps precede placement.

The fixture is then placed surgically under local anaesthetic. After a healing period, an impression or digital scan is taken and the final restoration is made and fitted. Individual cases vary widely — some are simpler, some require additional stages.

Candidacy considerations

Suitability depends on several things a dentist evaluates in person: the quantity and quality of bone at the site, gum health, general health and healing capacity, smoking status, medications that affect bone metabolism, and whether heavy clenching or grinding is present.

Implants are widely used and well studied, but no dentist can responsibly promise a specific result in advance. Success rates reported in research describe groups of patients, not individuals.

Living with an implant

Implants cannot decay, but the gum and bone around them can become inflamed — a condition called peri-implantitis, which behaves somewhat like gum disease and can lead to loss of support. Daily cleaning around the implant and regular professional maintenance are therefore not optional extras.
