Accidental ingestion of an inter-occlusal device used for the restoration of occlusion: a case report.

The accidental swallowing of prosthetic devices has been discussed in the relevant literature as an unusual, although ordinary, event in clinical practice. This article aims at reporting the ingestion of an inter-occlusal device used to restore the Vertical Dimension of Occlusion (VDO) which, during the ingestion of an analgesic pill, was accidentally swallowed. The patient was sent to the Clinics Hospital UFMG where, upon taking radiographs, the device was located in the upper third of the esophagus.

Effects of coronal substrates and water storage on the microhardness of a resin cement used for luting ceramic crowns.

Unlabelled: Composite resin and metallic posts are the materials most employed for reconstruction of teeth presenting partial or total destruction of crowns. Resin-based cements have been widely used for cementation of ceramic crowns. The success of cementation depends on the achievement of adequate cement curing.

Intra- and extraoral prostheses retained by zygoma implants following resection of the upper lip and nose.

Upper lip cancers are infrequent lesions, being aggressive unless diagnosed and treated early. After the surgical resection, maxillofacial defects require special care in rehabilitation. This article describes the maxillofacial rehabilitation of an edentulous patient diagnosed with upper lip squamous cell carcinoma.

Stress analysis of a fixed implant-supported denture by the finite element method (FEM) when varying the number of teeth used as abutments.

Objectives: In some clinical situations, dentists come across partially edentulous patients, and it might be necessary to connect teeth to implants. The aim of this study was to evaluate a metal-ceramic fixed tooth/implant-supported denture with a straight segment, located in the posterior region of the maxilla, when varying the number of teeth used as abutments.

Material And Methods: A three-element fixed denture composed of one tooth and one implant (Model 1), and a four-element fixed denture composed of two teeth and one implant (Model 2) were modeled.

Light transmission through porcelain.

Objective: This study evaluates the effect of shade and thickness of porcelain in light transmission.

Methods: One hundred and twenty-eight disks of Duceram porcelain were made to combine four different thicknesses (1.5; 2.

The influence of occlusal finish line configuration on microleakage of indirect composite inlays.

Purpose: The aim of this in vitro study was to evaluate the influence of occlusal finish line configuration on microleakage of indirect composite inlays.

Materials And Methods: Forty-five recently extracted premolars were randomly assigned into three groups with different types of occlusal finish line preparations: bevel, chamfer, and butt joint. All restorations were made in Artglass (Heraeus Kulzer) and luted according to the manufacturer's recommendations.
