Abstract

Tooth loss is a common problem which affects the oral cavity but also hinders the overall health of a person.Common consequences of tooth loss include progressive alveolar bone resorption and decreased masticatory performance.Edentulism affects oral and general health in addition to quality of life .Both disability and handicap have been associated with a negative impact on psychosocial well-being, especially when considering elders.Treatment for edentulism includes conventional complete dentures (CCDs), implant-retained overdentures (IODs) and, in some cases, implant supported full arch fixed complete denture prostheses.Common problems, especially with mandibular CCDs, include lack of stability and retention, soreness and pain and further loss of function.Overdentures are used as a treatment option in dentistry for more than hundred years.Implant retained overdentures are cost effective and maintainence is also easier compared to implant supported restorations.An evaluation of the long-term outcome of mandibular implant overdentures in relation to maxilla may provide useful guidelines for the clinician.Therefore, this systematic review was designed with an objective to evaluate the effect of mandibular overdenture on edentulous maxilla.
