Denture fracture is a common clinical complication caused by improper material selection, design, or fabrication technique. This study aimed to investigate the effect of two attachment systems on fracture risk of the implant-overdentures (IOD) via finite element analysis (FEA), using the force distributions obtained from patients' occlusal analyses and to compare the obtained results with the clinical complications associated with these attachments. A three-dimensional jaw model comprised of the edentulous bones was constructed...

PURPOSE: Several studies reported better outcomes when restoring edentulous mandible with unsplinted IODs compared to CCDs; however, it is not clear if these outcomes remain when the full literature is considered. The aim of this systematic review is to compare conventional complete dentures (CCDs) to unsplinted implant-retained overdentures (IODs) with regard to efficacy, satisfaction and quality of life. STUDY SELECTION: The main question addressed was: How do CCDs compare to unsplinted IODs with regard to efficacy, satisfaction and quality of life? Three databases were electronically searched to identify articles comparing CCD to unsplinted IOD...

The lack of compatible prosthetic components can be a complication during oral rehabilitations using outdated implants. The aim of the present clinical report was to describe an alternative technique for the fabrication of a maxillary implant-supported overdenture in a patient with 20-year-old dental implants using castable spherical patterns and ball-attachments. The patient had been wearing a relined bar/clip overdenture in the mandible on four external-hexagon dental implants and a relined complete denture in the maxilla on four internal-hexagon implants due to abutment screw fracture inside of the implants, losing the attachment system...

STATEMENT OF PROBLEM: Implant-supported overdentures (ISOs) are considered a good alternative to conventional removable dentures. However, varying rates of failure have been reported in some clinical studies. Excessive stress on surrounding tissues is one of the possible causes of implant failure. As stress is transmitted to the bone through the implant, careful planning, correct number of implants, and implant positioning are keys to ensuring appropriate stress distribution. However, research of the optimal number of implants necessary to support a maxillary ISO is insufficient...

PATIENT: This report describes the case of a 68 year old female patient who presented with the chief complaint of difficulty in chewing and poor aesthetics due to missing teeth. The patient was interested in saving the remaining natural teeth and desired minimal tissue coverage from the prosthesis. After consideration of all the factors involved, it was deemed advisable to resort to a palate free maxillary telescopic complete denture and a mandibular removable partial denture. DISCUSSION: Considering the age of the patient and the cost involved, implant supported prosthesis was ruled out as a treatment option for the patient...
