Evaluation of telescopic tooth-supported overdentures regarding surrounding supporting structures case study

Abstract

IntroductionOverdenture according to the glossary of prosthodontic is removable dental prosthesis that covers and rests on one or more remaining natural teeth, the roots of natural teeth, and/or dental implants1. Root-supported overdentures have been fabricated to correct periodontal and/or occlusal collapse, some teeth are maintained to support or retain the prosthesis and therefore, maximizing prosthesis stability, besides preserving proprioception of the periodontal ligament and reducing bone loss2. Telescopic copings have been used for several years in oral rehabilitation of patients with advanced periodontal disease. Patients with periodontal disease undergoing prosthetic reconstruction often present with teeth with minimal supportive tissue and increased tooth mobility. Therefore, it is extremely important for the prosthesis not to cause periodontal destruction or worsen an existing periodontal condition. ObjectiveThe aim of this study was an evaluation of telescopic mandibular tooth-supported overdentures regarding surrounding supporting structures both clinically and radiographically. Materials and methodA 55 years old male patient with few remaining natural teeth was selected from the outpatient clinic in Umm-Alqura university faculty of dentistry. As remaining teeth were periodontally compromised, and low the number of teeth in lower arch for a constructed removable partial denture, It was concluded that mandibular canines and premolars can serve as abutments for an overdenture. Analysis of the mounted cast was made to ensure sufficient space for construct overdenture. The treatment plan was divided into three phases: Phase 1: Caries excavation, Phase 2: Intentional endodontic treatment, Phase 3: Prosthodontic rehabilitation. RESULT: According to the clinical and radiographical measurements in the delivery visit and after one year from the treatment, we concluded that there is no obvious difference. ConclusionTelescopic overdentures have better retention and stability as compared to complete dentures, they improve the chewing efficiency and the comfort of the patient and they also decrease the alveolar bone resorption. According to the result, in this case, the attachment level in the patient mouth and bone change in height or width by cone beam computed tomography (CBCT), and the patient was satisfied from the denture and grateful.
