Gelareh Ronaghi, Winston Chee, Stephanie Yeung
This clinical report describes a method for predictably shade matching a highly opaque yttrium-stabilized tetragonal zirconia polycrystal (Y-TZP) implant restoration adjacent to relatively translucent lithium disilicate veneers in the maxillary anterior region. To achieve a satisfactory outcome, the milled Y-TZP abutment was layered with low-fusing feldspathic porcelain to match the stump shade of the adjacent prepared teeth; this layer subsequently facilitated adhesive bonding of a veneer to the abutment before insertion...

Gizem Dimililer, Sercan Kücükkurt, Sedat Cetiner
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...

Staged complete-mouth rehabilitation to accommodate a patient's financial constraints during the course of treatment is presented. Clear acrylic resin added to the anterior cameo surface of the maxillary fixed complete denture (FCD) served as a space maintainer. The restoration of the maxillary FCD addressed the patient's chief complaint. By adding the space maintainer, supraeruption of mandibular anterior teeth and encroachment of the prosthetic space, which could have resulted in additional treatment, was avoided...

The clinical application of real-time magnetic resonance imaging (MRI) for the diagnosis of temporomandibular joint disk displacement (DD) with and without reduction is presented. In 2 patients with presumed DD, real-time MRI at 15 frames per second was performed during the natural opening and closing of the mouth. In one patient unilateral DD with reduction and in the other patient bilateral DD without reduction were observed. In contrast with conventional static MRI, real-time MRI moving images of temporomandibular joint DD offer comprehensive information about the dynamics of all involved structures, which in turn promises more reliable diagnoses...

Eduardo Bortolas de Carvalho, Paulo Eduardo Herbst, Adriana Cláudia Lapria Faria, Ricardo Faria Ribeiro, Priscila Paganini Costa, Rodrigo Tiossi
STATEMENT OF PROBLEM: The loss of the first molar and second premolar could lead to mesial movement of the second molar, thus limiting the restoration space for the 2 missing teeth. Placement of a larger first molar is a common choice, but the best implant number and position option remain controversial. PURPOSE: The purpose of this in vitro study was to test different planning options for replacing the mandibular first molar. MATERIAL AND METHODS: Two polyoxymethylene models simulated first molar edentulous spaces of 11 mm (conventional size first molar: control group) and 14 mm (enlarged first molar: all remaining groups other than control)...

STATEMENT OF PROBLEM: The clinical use of ceramic resin-bonded fixed dental prostheses (RBFDPs) in the posterior region is desirable for esthetic and biological reasons but has been associated with many technical problems, including fractures or chipping of the veneer. Although these problems may be overcome by using monolithic zirconia, information is lacking about the load-bearing capacity of resin-bonded monolithic zirconia restorations for replacing a molar. PURPOSE: The purpose of this in vitro study was to compare the load-bearing capacity (Fu), the load at initial damage (F1d), and the failure pattern of posterior RBFDPs fabricated from monolithic zirconia (MZr), veneered zirconia (VZr), and veneered cobalt-chromium (VCo)...
