#1
Edward A McLaren, Nathaniel Lawson, James Choi, Juan Kang, Carlos Trujillo
Fabricating all-ceramic restorations with minimal or no application of a secondary phase while maintaining esthetics has been a sought-after goal of the dental profession. The objective has been development of a monolithic material with optical properties similar to the natural tooth without the need for layering porcelain. This article examines some of the newer cubic zirconia materials used in a monolithic form. The authors discuss laboratory-processing issues that affect esthetics, including evaluation of colorizing, sintering, finishing, and polishing, and assess initial translucency testing of several materials while evaluating the effect of air abrasion on flexural strength of these cubic zirconias...

André V Ritter, Newton Fahl, Marcos Vargas, Rodrigo R Maia
In the direct-indirect composite technique, composite is applied to a nonretentive tooth preparation (eg, a noncarious cervical lesion or a veneer/inlay/onlay preparation) without any bonding agent, sculpted to a primary anatomic form, and light-cured. The partially polymerized restoration is then removed from the preparation and finished and tempered extraorally chairside. The finished inlay is bonded to the preparation using a resin-based luting agent. Advantages of this technique include enhanced physical and mechanical properties afforded by the extraoral chairside tempering process because of increased monomer conversion, and greater operator control over the final marginal adaptation, surface finishing and polishing, and anatomy of the restoration, given that these elements are defined outside of the patient's mouth...

Pain from local anesthesia injections can be reduced by distraction and counter-stimulation techniques. This study investigated the DentalVibe® Injection Comfort System (third-generation, DV3), developed to lessen anesthesia pain through pulsed vibration, a form of counter-stimulation. The aim of the study was to evaluate both the efficacy of DV3 in reducing pain and discomfort from intraoral long buccal (LB) and inferior alveolar nerve (IAN) injections and the time needed to achieve complete anesthesia during an IAN block...

Amna Adam Ibrahim, Mohammed Nasser Alhajj, Nadia Khalifa, Magdi Wadie Gilada
Alginate impression (irreversible hydrocolloid) material is commonly used in dental practice because it is easy to mix, low in cost, and well tolerated by patients. The material is not dimensionally stable, however; thus, it is necessary to pour the impression immediately after the molding is accomplished, or within 60 minutes if the impression is kept in 100% humidity. Excessive contact of the alginate impression with the cast model over time may affect the model's properties. In this study, the authors tested the effect of contact time between an alginate impression and type III dental stone on cast model properties...

Andrew Spath, Colby Smith
With the overwhelming acceptance of lithium disilicate and zirconia, the frequency with which dentists have to remove these materials is increasing, and this can be difficult. Proper cement usage for full-coverage crowns with preparations that have retention and resistance can be helpful if in the future the restoration needs to be removed. When removing these modern materials, bur and laser techniques are both effective means, with each having specific benefits. Materials selection and preparation design are vital when considering areas of risk each patient exhibits and the potential need for removal...

Paul S Petrungaro
Dental implants have become a suitable treatment option for patients experiencing tooth loss and a popular choice among clinicians for immediate tooth replacement. Because of modifications in implant designs and development in immediate restoration and loading protocols, dental implant treatment can be reduced to a single procedure instead of multiple processes, hence providing the patient with a streamlined treatment that is typically much less invasive with immediate-tooth replacement. The purpose of this paper is to review the immediate restoration of dental implant(s) procedure and validate its position in treatment protocols by presenting success rates documented for more than 15 years and with 5000 implants...

The "medical model" is a term coined for a set of procedures in which American physicians are trained. For dentistry, the sequentially ordered set of procedures includes: (1) immediate concerns; (2) medical/ dental histories; (3) physical examination findings; (4) ancillary tests, if needed; (5) diagnosis; (6) risk assessment; (7) prognosis without treatment; (8) treatment-plan options/informed consent; (9) treatment; (10) post-treatment assessment and verification. This case report demonstrates a diagnostic system using the medical model via linear thinking-ie, step-by-step progression-to diagnose and conservatively treat a patient with a constricted chewing pattern...

Lisa Germain, Louis Malcmacher
Temporomandibular disorders (TMD) are a group of conditions affecting the temporomandibular joint and/or muscles of mastication. TMD may present along with many comorbid pain syndromes such as myofascial pain, headache, and neck and back stiffness with limited range of motion, as well as fibromyalgia and chronic fatigue syndrome. The diagnosis and management of TMD is complex and, many times, multidisciplinary. However, dentists can provide their patients with frontline temporomandibular/orofacial pain therapy with didactic and hands-on training that provides a better understanding and a conservative approach for treatment of TMDs...

Aliasger Tunkiwala, Rajeev Chitguppi
This article demonstrates the clinical application of biomechanical and occlusal principles to conservatively provide optimal clinical outcomes in restoring an eroded anterior dentition. The authors manage a challenging case involving limited palatal clearance (ie, deep bite) coupled with palatal erosion and wear by combining the centric relation (CR) and Dahl principles to create anterior interocclusal space to reduce the need for more invasive palatal reduction. The combined use of adhesive restorations-resin composites on the palatal surface and indirect porcelain veneers on the facial/incisal surfaces-through enamel and dentin bonding helped optimize esthetic and functional/biomechanical aspects...

Megan Todd, William Brackett, Mario Romero
For patients with a single discolored tooth who desire to have it lightened, a thorough examination and radiographic analysis need to be performed prior to initiating any bleaching treatment so that the cause of the discoloration can be determined. Underlying pathology, such as internal resorption, is often asymptomatic and difficult to diagnose and if left untreated could result in tooth loss. This article describes a case of a patient with a discolored maxillary central incisor resulting from internal resorption and the subsequent endodontic and bleaching therapy performed to resolve the pathology and achieve an acceptable esthetic result...

Lanka Mahesh, Gregori Kurtzman, Sagrika Shukla
Placement of an implant in the posterior maxilla often relies heavily on a variety of procedures that increase the vertical dimensions of available bone. With numerous bone graft substitutes now available and recent advancements having been made in technique, the question arises of whether residual bone height still remains an absolute indicator for simultaneous implant placement in lateral wall sinus grafting. In addition to reviewing the literature, the authors present a case in which a direct sinus lift procedure was performed with simultaneous implant placement...

Lasers are a relatively new addition to the orthodontist's armamentarium. This article reviews the fundamental basic science of available soft-tissue lasers, with an emphasis on diode lasers, and discusses various adjunct applications of the diode laser for soft-tissue orthodontic procedures. Diode lasers function by cutting with an initiated hot tip and produce minimal to no interaction with healthy dental hard tissue, making them suitable for soft-tissue procedures. The contact cutting mode provides enhanced bloodless site visibility and facility to perform delicate soft tissue procedures, which is important in areas with difficult access...

The goal of periodontal plastic surgery is to correct the soft-tissue deformities associated with the loss of attached and keratinized tissue. A variety of flap manipulations related to the use of subepithelial connective tissue grafts are described with great success in the literature but are linked with morbidity and harvesting-quality issues, inclining clinicians and researchers to find alternatives to such techniques. Advanced platelet-rich fibrin, which is widely used in medicine and oral therapy, represents a newer generation of blood-derived growth factors...
