When lower teeth have been missing for many years, the bone of the lower jaw becomes progressively thinner. In extreme cases the lower jaw may be as thin as a pencil and this makes denture wearing virtually impossible. A treatment option before the bone becomes so thin is to place two implants in the lower jaw for the denture to “click” onto. Such a denture is called an “overdenture”. Not only does the denture now become much more secure, but the bone loss is markedly reduced.

As far back as 1997, a study by Dr D. Wismeijer and colleagues from the Amsterdam Dental School examined the results for 110 patients who had difficulty wearing a lower denture and who were provided with overdentures. A high level of patient satisfaction was found.

A more recent study by Dr SA Alfadda and colleagues from the University of Toronto, found a similar level of satisfaction for 77 patients given implanted-supported mandibular overdentures.

Mandibular overdentures are a very successful and cost-effective treatment option for patients who lose all their lower teeth.
