Effect of silver-nanoparticles reinforced resin on Candida growth and fracture resistance of maxillary complete dentures: In vitro evaluation

Few remaining healthy teeth in a patient who is concerned about appearance is very challenging for the prosthodontist, especially if the patient can’t afford for implant supported prosthesis and the fixed replacement couldn’t be an option for managing such case. Partial overdenture arises to be the saver in these cases where dome shape reduction reduces the mobility of the tooth by improving the crown root ratio and doesn’t require the biological width needed for the preparation of the fixed restoration. Thus preserve the tooth and the surrounding alveolar bone and provide support to the removable prosthesis. The management of occlusal problems due to long period being partially edentulous without restoring the missing teeth requires first an analysis phase to the existing occlusion, and a prosthetic wax up of the proposed prosthesis on the mounted diagnostic casts to guide the treatment plan properly and all the steps of rehabilitation. Taking into consideration the functional and esthetic outcomes to achieve patient’s satisfaction. The case presented highlights the importance of detailed clinical and radiographic examination in addition to analysis of the available prosthetic spaces on mounted diagnostic casts aiming to the success of managing it. Besides, showed the effectiveness of using thermoplastic partial overdenture for patients with labial undercuts and limited inter-arch space. After one-year follow-up, the patient was satisfied with the esthetics and easy of use of the thermoplastic as well as the metallic prostheses.
