A case report on tooth-supported overdenture with an extra-radicular attachment

Abstract

Introduction: Over-dentures are the most commonly used treatment for elderly patients who still have two or more teeth in their arch. When using coping or attachment over the remaining part of the tooth, the root of the remaining teeth preserves the alveolar ridge, provides sensory sense, and improves the stability and retention of the denture when compared to conventional complete dentures. This report presents a case of rehabilitation of partially edentulous 55 year old male patient who had a chief complaint of poor esthetics and difficulty in chewing due to missing teeth.Method: Considering the age of the patient and the cost involved, implant supported prosthesis was ruled out as a treatment option for the patient. A tooth supported overdenture was chosen as a favorable treatment option since it overcomes many of the problems posed by conventional complete dentures. Extra- radicular attachments were used to improve the retention and stability.Result: Evaluation of occlusion, esthetics, phonetics and comfort after 24 hours, 1 week and 1 month, 6 months of treatment showed that the patient was satisfied with the prosthesis.Conclusion: The denture's stability and retention are improved on using tooth-supported over-denture retained with extra-radicular attachment. This treatment option provides improved chewing efficiency, patient comfort and reduce the residual ridge resorption.Clinical Significance: Prosthetic rehabilitation by means of tooth supported overdenture maintains the integrity of residual alveolar ridge, provides more bone support and helps in preservation of sensory input by facilitating enhanced occlusal awareness, biting force and neuromuscular control from the periodontal tissue.
