Incorporating Stud Attachments in the Bar Design for an Implant-Supported Overdenture.

Bone resorption following tooth loss might compromise retention, stability, and support of conventional removable prostheses, and for this reason, implant-supported overdentures are suggested as a viable alternative for completely edentulous patients. Bars, telescopic attachments, or stud attachments have been used to provide retention through a different mechanism of action based on specific design characteristics. The purpose of this report is to thoroughly describe the applied protocol for the fabrication of an implant overdenture supported by two bars incorporating stud attachments.

Effect of in vivo aging on the surface and electrochemical properties of magnetic attachments used in facial prostheses: A retrieval analysis study.

Statement Of Problem: Reasons associated with the failure of facial prosthesis are of major concern and may be associated with deterioration of both elastomeric materials and magnetic attachments. However, the extent of deterioration of these components is unclear.

Purpose: The purpose of this in vitro study was to evaluate selected retrieved facial prostheses and provide information regarding the electrochemical characterization of the recovered magnetic attachments.

Incorporation of the Altered Cast Technique in the Fabrication Workflow of an Implant-Assisted Removable Partial Denture (IARPD) for an Elderly Patient.

Implants are currently used to serve as abutments for implant-assisted removable partial dentures (IARPDs) to facilitate retention and support of the prosthesis. Implants are proposed in cases of posterior edentulous areas to convert Kennedy Class I or II to Class III or when the preparation of existing teeth to serve as abutments is contraindicated. The purpose of this report is to describe the protocol applied to fabricate an IARPD to restore a Kennedy Class II mandible of an elderly patient by incorporating traditional methods, such as the altered cast technique.

Effect of spatial arrangement and clinical service lifetime simulation on the retention of magnetic units used in implant-anchored orbital prostheses.

Statement Of Problem: Evidence for the optimal spatial arrangement of magnetic attachments in implant-supported orbital prostheses is lacking.

Purpose: The purpose of this in vitro study was to assess the effect of 6 different spatial arrangements on the retentive force of magnetic attachments following the in vitro simulation of clinical service by insertion-removal test cycles and the contribution of artificial aging to the morphological alterations induced on the magnetic surfaces.

Material And Methods: Ni-Cu-Ni plated disk-shaped neodymium (Nd) magnetic units (d=5 mm, h=1.

Prosthodontic restoration of a COVID-19 associated mucormycosis defect: A clinical report.

Introduction: Coronavirus Disease 2019 (COVID-19) pandemic brought the clinical practice of dentistry and prosthodontics at the threshold of a new era, due to the increasing prevalence of a relative rare condition normally affecting the immunocompromised patients.

Aim: The aim of this clinical case report is to briefly describe the etiopathogenesis, the surgical and prosthodontic management of this evolving medical condition emphasizing the emerging role of the maxillofacial prosthodontist in restoring the patients' well-being.

Methods And Results: The surgical and prosthodontic rehabilitation of a COVID-19 infected patient with a mucormycotic lesion of the maxilla will be presented.
