Implants (osseointegration)
The insertion of titanium posts into the jaw bone onto which crowns are fixed. The discovery that Titanium could be implanted into bone was made in Sweden by Professor Branemark in the 1970s. Given the right clinical conditions he found that cylinders of titanium could be implanted into human bone and after a few months they become inseparable.

Inlays and Onlays
A procedure to restore teeth.

Inlay - fits inside the tooth Onlay - fits over the tooth They are made of various substances e.g. gold, porcelain, etc and last for about 10 to 15 years. They are cemented or bonded to the tooth.
Insurance
The covering of dental costs by regular payments. There are various schemes available: capitation, insurance and cash plans. Capitation - Premiums are calculated based on the patients dental condition so, those with poor teeth can expect to pay a higher premium. Many plans will require dental fitness before acceptance and contain provisions for additional charges such as laboratory fees where crowns, bridges, dentures etc. are concerned. Expensive items such as implants are excluded. Insurance - These low cost schemes provide a generous cash benefit for the restoration of teeth in the event of damage from an accident. Benefit for the treatment of oral cancer is usually also included. Advanced materials and dental technology in the form of titanium implants can bring about the most incredible restorative transformation. This treatment is expensive and not available under the NHS.
