Effect of mini implant number and distribution on the supporting structure of implant retained mandibular overdentures

Abstract

Edentulism is defined as loss of all permanent teeth. It affects millions of people and considered to be an unresolved issue of sustained significance in the old age. It is considered to have several negative effects on the patient. It is associated with a residual ridge resorption, altered facial form, diminished masticatory function and subsequently a reduced general health and quality of life (1). The classical treatment option for the edentulous patients is the conventional complete denture. While this treatment option is inexpensive and restores most functions, it has several drawbacks in regard to the supporting structures, retention, and stability. Many patients are satisfied with implant supported overdenture that is simple, less invasive and less expensive (2).
