Kuntal S Kadam et al 22 IJOICR Implant-supported Overdenture 1 Kuntal S Kadam, 2 Shankar P Dange, 3 Kishore Mahale, 4 Smita A Khalikar, 5 Arun Khalikar ABSTRACT Edentulous patients often experience problems with their mandi- bular complete dentures. Patients with the resorbed mandibular ridge often complain of lack of stability and retention of the man- dibular denture, together with a decreased chewing ability. While implant-supported fxed prosthesis offers many advantages, they are very expensive and not indicated in many conditions. Implant- supported removable prosthesis can be a choice of treatment in such cases. This clinical report describes a method to rehabilitate a patient with resorbed mandibular ridge with implant-supported overdenture. Keywords: Implant, Restoration, Tooth replacement.

Source of support: Nil Confict of interest: None INTRODUCTION Edentulous patients often experience problems with their mandibular complete dentures. Patients with the resorbed mandibular ridge often complain of lack of sta- bility and retention of the mandibular denture, together with a decreased chewing ability. 1 Insertion of implants creates more favorable environment for the restoration in such patients. Implant-supported prostheses options for an edentulous arch include implant-supported fixed prosthesis and implant-supported removable prosthesis. While implant-supported fixed prosthesis offers many advantages like being esthetically pleasing and feels being actually like natural dentition, they are very expen- sive and not indicated in many conditions. 2 Implant- supported removable prosthesis offers certain advantages over implant-supported fixed restoration. 2 Many patients are satisfied with a stable implant-supported overdenture that requires limited clinical time and financial expense. 1 CASE REPORT 1 Postgraduate Student, 2 Dean and Professor, 3 Professor and Head, 4,5 Associate Professor 1-5 Department of Prosthodontics, Government Dental College and Hospital, Aurangabad, Maharashtra, India Corresponding Author: Kuntal S Kadam, Postgraduate Student, Department of Prosthodontics, Government Dental College and Hospital, Aurangabad, Maharashtra, India, Phone: +919422504343, e-mail: drkuntalkadam@gmail.com 10.5005/jp-journals-10012-1162 This clinical report describes a method to rehabilitate a patient with resorbed mandibular ridge with implant- supported overdenture. CASE REPORT A 49-year-old female reported to the Department of Prosthodontics, Government Dental College and Hospi- tal, Aurangabad, India, with the chief complaint of dif- ficulty in chewing food and loose-fitting lower denture. Patient had been edentulous since past 1.5 years due to extraction of periodontally compromised and carious teeth. She had been using a set of complete dentures for past 6 months and was not satisfied as lower denture was not stable and fitting well. Clinical examination revealed edentulous maxillary and mandibular ridges with class I ridge relation (Fig. 1). Mandibular ridge was resorbed (Atwoods class IV). Patient was informed about various treatment options available. Implant-supported fixed prosthesis could not be planned as lip support and esthetics would not be improved. As patient was primarily concerned about retention of the dentures, it was decided to rehabilitate the patient using mandibular implant-supported overdenture opposing maxillary complete denture. Diagnostic impressions were made. Diagnostic ortho- pantomogram (OPG) and casts, records were studied. Implant placement was planned at B and D positions after obtaining consent from patient (Misch’s overdenture options – OD1). 2 Treatment was divided into three phases: (1) diagnostic denture fabrication, (2) implant placement, and (3) final prosthesis fabrication.
