BACKGROUND: Oral health in nursing home residents is poor. Robust, mandated assessment tools such as the Resident Assessment Instrument - Minimum Data Set (RAI-MDS) 2.0 are key to monitoring and improving quality of oral health care in nursing homes. However, psychometric properties of RAI-MDS 2.0 oral/dental items have been challenged and criterion validity of these items has never been assessed. METHODS: We used 73,829 RAI-MDS 2.0 records (13,118 residents), collected in a stratified random sample of 30 urban nursing homes in Western Canada (2007-2012)...

This study evaluated the effect of implant diameter on strain around implants retaining mandibular overdentures with Locator attachments. Three mandibular acrylic resin models were constructed with 2 implants inserted in canine areas and classified according to implant diameter into 3 groups: large (4.2 mm), medium (3.7 mm), and small (3.3 mm) diameter implants. Duplicate dentures were connected to the implants with Locator attachments. Four strain gauges were bonded to the acrylic resin at mesial, distal, buccal and lingual surfaces of each implant and strain was measured at loading and non-loading sides during 1st premolar and 1st molar loading...

Zirconia (ZrO2) based dental ceramics have been considered to be advantageous materials with adequate mechanical properties for the manufacturing of medical devices. Due to its very high compression strength of 2000 MPa, ZrO2 can resist differing mechanical environments. During the crack propagation on the application of stress on the surface of ZrO2, a crystalline modification diminishes the propagation of cracks. In addition, zirconia's biocompatibility has been studied in vivo, leading to the observation of no adverse response upon the insertion of ZrO2 samples into the bone or muscle...

A foreign body impacted in the esophagus is not a rare incident among adults or children. In adults, a dental prosthesis is prone to become impacted in the esophagus. The diagnostic difficulty of this often causes a delay in its removal, which can lead to serious complications, including death. This report describes the autopsy case of a man who died of prolonged asphyxiation induced by the delayed removal of an impacted denture, which was misdiagnosed on his first visit notwithstanding that a part of the denture could be seen on X-rays...

Allergic and hypersensitivity reactions to dental impression materials may occur throughout dental treatment, with diverse manifestations from slight redness to severe pain and a burning mouth with total stomatitis. Patients are often unaware of these allergic reactions, which makes early identification of the cause almost impossible. In addition, symptoms usually begin after 24 hours and mostly in patients with a preexisting history of allergic responses. This report describes a patient with a suspected allergic reaction to a polyether dental impression material during prosthetic rehabilitation associated with a mandibular telescopic denture...

STATEMENT OF PROBLEM: Reports on computer-engineered complete dentures (CECDs) continue to increase. Systematic reviews on clinical outcomes and applications associated with CECDs are lacking in the literature. PURPOSE: The purpose of this systematic review was to determine the clinical outcomes and applications of CECDs. MATERIAL AND METHODS: Electronic searches of the English literature from January 1984 to May 2016 were performed in MEDLINE and Cochrane databases, with the results enriched by hand searches and citation mining to address 2 relevant population intervention comparison outcome (PICO) questions: What are the clinical outcomes associated with CECDs? Are there specific applications and significant advantages for CECDs? RESULTS: A review of the selected articles on CECDs revealed significantly better retention and reduced clinical time for the milled CECDs compared with conventional complete dentures...

Implant-supported fixed complete dental prostheses have been associated with a high implant success rate in long-term studies. However, they have also been associated with a high frequency of prosthetic complications. The most frequent and primary prosthetic complication has been the fracture or wear of the occlusal surface of acrylic resin teeth that are typically attached to a metal framework. The design of the framework in this clinical report involved the incorporation of metal occlusal surfaces for the posterior first molars to the framework...

Aging is associated with loss of teeth, resorption of the alveolar process, and reduced tonicity of the facial muscles, leading to sunken cheeks and an unesthetic appearance. Esthetics in patients in need of complete dentures can be improved with the help of cheek plumpers to support the cheeks. They are noninvasive and straightforward to fabricate. Despite the reported success with the sole use of maxillary cheek plumpers, in certain situations, maxillary cheek plumpers provide inadequate support to the cheeks, evident in the lower third of the face...
