Dental implant placement in the esthetic zone requires knowledge of various concepts and techniques, and a thorough oral examination of both hard and soft tissues. A meticulous treatment plan can then be developed, which ultimately will lead to an esthetically pleasing result. In this case report, the author has described key elements for successful implant restoration in the esthetic zone.

Esthetic Treatment Of Minor Malaligned Maxillary Anterior Teeth Using A Removable Orthodontic Appliance, Tooth Whitening, And Veneer, Pauline Lamsam, Chalermpol Leevailoj, Supaporn Suttamanatwong

Chulalongkorn University Dental Journal

Objective This case report describes the esthetic treatment of mildly crowded maxillary anterior teeth using a removable orthodontic appliance, bleaching, composite resin and porcelain veneer to maximize the treatment results. Materials and methods A 28-year-old male with minor crowding of the maxillary anterior teeth wanted his teeth to look straight and unnatural extremely white color. A treatment plan was developed with the priority being orthodontic treatment to move teeth into alignment. Then the patientûs expectations were adjusted based on information from the team dentists. By the end of whitening treatment, the patient was satisfied with the whiteness of his teeth …

Smile Makeover In An Esthetic-Compromised Patient: A Multidisciplinary Approach, Chatsuda Pawasoottikul, Chalermpol Leevailoj, Niramol Chamnannidiadha

Chulalongkorn University Dental Journal

This article is a case report of a patient who lost left permanent maxillary lateral incisor, canine and left permanent maxillary first premolar and alveolar bone due to the enucleation of eosinophilic granuloma. Also, the report described how a multidisciplinary approach may improve the esthetic outcome when only orthodontic treatment was insufficient. The early loss of permanent anterior teeth affected the harmony of the incisors shown and ultimately the esthetics of the smile, and was a challenge in treatment planning. The recurring esthetic dental (RED) proportion was used for space distribution. Esthetic crown lengthening was indicated to improve the gingival …

Extensive Population Structure In San, Khoe And Mixed Ancestry Populations From Southern Africa Revealed By 44 Short 5-Snp Haplotypes, Carina M. Schlebusch, Himla Soodyall

Human Biology Open Access Pre-Prints

The San and Khoe people currently represent remnant groups of a much larger and widely distributed population of hunter gatherers and pastoralists who had exclusive occupation of southern Africa before the arrival of Bantu-speaking groups in the past 1,200 years and sea-borne immigrants within the last 350 years. Genetic studies (mitochondrial DNA and Y-chromosome) conducted on San and Khoe groups revealed that they harbour some the most divergent lineages found in living peoples throughout the world. Recently, high-density autosomal SNP-array studies confirmed the early divergence of Khoe-San population groups from all other human populations. The present study made use of …

Foreclosure And Other Essays, Derick Brandon Strode

Masters Theses & Specialist Projects

My dad had early onset Alzheimer’s disease. I first knew something was wrong with him in 1995. He was 49 then, and I was just about to start the eighth grade. That’s the summer his company backed him into a corner and told him to quit or be fired. He had worked there 14 years. They said his behavior was changing, and they thought he was doing it on purpose. It took seven years to get an actual diagnosis. The doctors looked for everything. They just thought he was too young.

I’ve relied on materials found in my parents’ house …

Migration Of The Swine Influenza Virus -Δ Cluster Hemagglutinin Nlinked Glycosylation Site From N142 To N144 Results In Loss Of Antibody Cross-Reactivity, Ben Hause, Douglas L. Stine, Zizhang Sheng, Zhao Wang, Suvobrata Chakravarty, Randy R. Simonson, Feng Li

Chemistry and Biochemistry Faculty Publications

Routine antigenic characterization of swine influenza virus isolates in a high-throughput serum neutralization (HTSN) assay found that approximately 20% of isolates were not neutralized by a panel of reference antisera. Genetic analysis revealed that nearly all of the neutralization-resistant isolates possessed a seasonal human-lineage hemagglutinin (HA; δ cluster). Subsequent sequencing analysis of full-length HA identified a conserved N144 residue present only in neutralization-resistant strains. N144 lies in a predicted N-linked glycosylation consensus sequence, i.e., N-X-S/T (where X is any amino acid except for proline). Interestingly, neutralization-sensitive viruses all had predicted N-linked glycosylation sites at N137 or N142, with threonine (T) …

The Impact Of Corruption On Firm Tax Compliance In Transition Economies: Whom Do You Trust?, Anna Alon, Amy M. Hageman

Faculty Publications

Tax compliance is an important issue for governments and the public alike. To meet public needs and fund public mandates, firms around the world are expected to comply with tax laws. Factors that are related to organizational (firm) tax compliance have not been sufficiently examined in the literature. Due to the increasing global influence of transition economies, factors associated with firm tax compliance in transition economies are particularly of interest. Based on a sample of over 5,000 firms from 22 former Soviet Bloc transition economies, we find that higher levels of corruption and higher levels of particularized trust (reliance on …

Values-Driven Leadership Development: Where We Have Been And Where We Could Go, Mary C. Gentile

Organization Management Journal

This essay revisits the premises upon which business ethics education has been based and then “flips” them, in an effort to help transform management education’s approach to valuesdriven leadership development. Previous assumptions about what we teach, who we teach, and how we teach ethics are described, and a summary of how the Giving Voice to Values (GVV) pedagogy/curriculum flips these assumptions is provided. A brief review of the impact to date of this experiment is included, along with reflection on some of the new opportunities and challenges GVV has begun to face as a result of the rapid take-up of …

Dynamic Field Test Of A Model Levee Founded On Peaty Organic Soil Using An Eccentric Mass Shaker, E. T. Reinert, S. J. Brandenberg, J. P. Stewart, R. E.S. Moss

Civil and Environmental Engineering

A dynamic field test of a model levee was performed to study the behavior of very soft and compressible peaty organic soils that commonly underlie levees in the Sacramento / San Joaquin Delta in northern California. This first-of-its-kind test applied dynamic loads to the levee/peat system using a large eccentric mass shaker mounted on the levee crest. Loads from the shaker and the inertia of the levee section are transmitted to the peaty organic soils as base shear stresses, and rotational demands that manifest as normal pressures at the embankment/peat interface. We seek to characterize the transmission of seismic energy …

Politics Or Policy? How Rhetoric Matters To Presidential Leadership Of Congress, José Villalobos, Justin Vaughn, Julia Azari

Selected Works Temporary Series

In this study, we examine the linkage between presidential policy proposal messages and legislative success. Employing a dataset on presidential legislative proposals that covers the years 1949-2010, we find that politics matters less than policy. Purely political messages that reference the electoral logic of mandates or appeal to a sense of bipartisanship appear to have no impact on presidential legislative success, nor does policy signaling, though highlighting the role of agency-based policy experts in crafting legislation does. From these results, we conclude that although the way presidents communicate their messages to Congress represents an important component of presidential-legislative relations, it …

The Policy Czar Debate, Justin Vaughn, José Villalobos

Selected Works Temporary Series

Presidential policy czars have been an important and powerful component of President Barack Obama’s approach to management and leadership in the first part of his time in office. By using czars, the President has been able to demonstrate the importance of policy issues, both to his own agenda and to the broader political system. In this chapter, we find that performance outcomes for these czars have been a mixed bag, with as many stories of success to report as tales of frustration and failure. As such, we posit that the cost of czars, in political and organizational terms, has outweighed …

Michigan Journal of International Law

In 2003, Paul Hunt, the U.N. Commission on Human Rights' Special Rapporteur on the Right to Health, presented a report on the global availability of health care. Special Rapporteur Hunt argued that states are obligated to implement a right to health. Included in this right is the obligation "to ensure that no international agreement or policy adversely impacts upon the right to health, and that .. . international organizations take due account of the right to health, as well as the obligation of international assistance and cooperation, in all policy-making matters." One area Hunt left unexplored in his report was …
