Dental Implants – Threaded Expanders For Bone Expansion

People lose teeth all the time, either through trauma (when teeth are knocked out) or due to decay, gum disease or old age. Whatever the reason for losing your teeth, they need to be replaced, both for aesthetic and functional reasons. The most common treatments for missing teeth are either a denture or a fixed bridge. However, dental implants are now becoming a more popular treatment to replace missing teeth, as they provide a longer-term solution, slow down bone loss and preserve nearby healthy tooth tissue.

Threaded expanders are another group of instruments for bone expansion. They work by rotation, which differentiate them from the osteotomes, which work by impactation. Threaded expanders have an aggressive conical shape and penetrate the bone easily. The principal advantage is that they are less traumatic to the patient and that they can be used in the lower jaw. The rotation movement can be done with a wheel inserted in the back part of the expander, or if more resistance is present, with a racket wrench.

The principal disadvantage is that is easier to loose the direction of the preparation compared to the osteotomes. Anyway, in both cases an adequate training is important.

In most usual cases, where the expansion needed is not so important, the expanders can be work well. In more extreme cases, is usually necessary to split the ridge first and the make the expansion.
