This treatment is not a new concept and practitioners have successfully employed existing tooth structures or retained roots to assist with complete denture treatment for more than a century. Two or more, coronally modified or restored retained teeth abutments are frequently endodontically prepared and are used as abutments for an overdenture. The objective is to distribute stress concentration between retained abutments and denture-supporting soft tissues. Retained tooth abutments can give better retention, support, and stability to an overdenture and also provide proprioception which would otherwise be lost with conventional denture treatment. Implant retained prosthesis is an option but is sometimes not possible due to insufficient amount of bone or economic reasons. Implant-supported overdentures are mainly useful for mandibular ridges, as they have undergone resorption and offer better retention than traditional dentures. However, the cost of implants is quite high hence the use of fewer implants (2 instead of 4) offers a less expensive option for an edentulous patient. Placement of the implants for overdentures in the mandible should be planned explicitly, as masticatory load transmission in mandibular implant-supported overdentures differs substantially from that of implant-supported fixed restorations. Importance should also be given to location and the number of implants being placed in the dental arch, as well as the chewing function as horizontal forces and even moments can cause implant failure if these are ignored. Mandibular implant-supported overdentures are generally retained by at least 2 implants, which are placed in or slightly medial to the canine area. The loss of teeth is generally associated with esthetic, functional, psychological and social impairment of the individuals life which may have a high impact of the patient’s self-esteem and health. Periodontal disease and dental caries are indicated as main causes for the loss of teeth and are associated with cultural and social factors such as financial sources, educational level and the access to health services. In regards to the rehabilitation alternatives such as the use of dental implants, fixed prosthesis, removable partial or complete dentures, the overdenture rehabilitation is a viable I Case Report Overdenture is a good treatment option for elderly patients. It can be either be tooth supported or implant supported. Patients with few remaining teeth and Roots maintained under the denture base preserve the alveolar ridge, provide sensory feedback and improve the stability and retention of the dentures. Furthermore, the use of copings on the remaining teeth enhances the retention of the denture. It is a versatile and successful means of achieving long-term restoration of a partially edentulous jaw. Insertion and removal of the denture and routine oral hygiene are easy to perform. In an implantsupported overdenture, the optimal stress distribution on the implants and least denture displacement is desirable.
