Dental implants are metallic cylinders, made of titanium, that are surgically placed into the jaw bone where original teeth once existed. This root like cylinder, the dental implant, acts as a false root allowing a crown or bridge to be placed on top of it just as if it were a natural remaining root and tooth.
The use of dental implants to replace a missing tooth or teeth, unlike conventional crown and bridge work, does not involve the weakening of adjacent teeth by the removal of large amounts of tooth tissue. As adjacent teeth are not involved in the provision of dental implants, additional stresses, which otherwise would have been placed on these adjoining teeth, are avoided and their long- term prognosis, therefore, is much improved.
Conventional dental implants can be placed into healed extraction sites or, in many cases, into an extraction socket immediately the tooth is removed. In some cases a temporary tooth can also be fitted at the same time as the implant is placed. Due to their versatility and strength these are the most commonly used type of dental implants.
Mini Implants for Denture Stability
On average these implants cost just over half the price of conventional implants and they may, therefore, be an option for those patients who have previously discounted the idea of implants due to cost. These implants may only be used in certain circumstances and when a tooth or teeth requiring replacement have been missing for at least 6 months and the site is fully healed.
There are 2 main advantages to this design:
No surgery is required to place these implants. Once the area is anaesthetised (numb), a small pilot hole is drilled straight through the soft tissue and into the bone – no cutting of the tissue is required and, therefore, no sutures are required either. The implant is then screwed into place making the procedure very quick and almost painless.
The type of thread on the implant allows for a very tight union between the implant and the bone thus allowing teeth to be fitted immediately. Also, because of its taper, the implant expands the available bone and, in many cases, allows implants to be placed in a reduced volume of bone without having to go through separate bone augmentation procedures
