ATTACHMENT-RETAINED TOOTH-SUPPORTED IMMEDIATE OVERDENTURE – A CASE REPORT
Abstract
Over denture treatment uses a removable complete denture that overlies retained teeth, tooth roots, or dental implants. 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.1,2 The presence of a healthy periodontal ligament maintains alveolar ridge morphology, whereas a diseased periodontal ligament, or its absence, is associated with variable but inevitable time-dependent reduction in residual ridge dimensions.3 To avoid this, two or more, coronally modified or restored retained teeth abutments are frequently endodontically prepared and are used as abutments for an over denture. The objective is to distribute stress concentration between retained abutments and denture-supporting soft tissues.4,5 Retained root abutments can give better retention, support, and stability to an overdenture and also provide proprioception which would otherwise be lost with conventional denture treatment. Attachments may not be used by many dental professionals for reasons such as cost and reluctance to grasp the intricacies of their indications and applications. An attachment retained dental prosthesis can improve patient aesthetics and facilitate function.6-8 Implant retained prosthesis is an option but is sometimes not possible due to insufficient amount of bone or economic reasons.
