Nanosuperfície de Titânio como uma nova realidade na implantodontia: Revisão de Literatura / Nano-surface Titanium a new reality in implant dentistry: Literature Review

Resumo: A odontologia vem buscando cada vez mais métodos de reabilitação dentária que sejam menos traumáticos e eficazes estética e visualmente falando. Sob esse aspecto, os implantes dentários têm se desenvolvido cada vez no intuito de garantir a satisfação dos pacientes, através de avanços tecnológicos como o da Nanosuperfície de Titânio. Assim, o presente estudo objetiva abordar a questão das superfícies de implantes de titânio no que se refere à sua capacidade de estímulo na formação óssea, por ser uma técnica que diminui o tempo de osseointegração e, consequentemente, a duração do processo e recuperação do paciente. Para tanto, foi realizada uma revisão bibliográfica em bases de dados eletrônicas acerca do tema, que comprovassem a diminuição de tempo do trabalho do profissional da Odontologia e uma melhor qualidade no que se refere aos implantes dentários, através da análise de três marcas nacionais a fim de comprovar sua eficácia. Palavras-chave: Implante dentário. Nanosuperfície de Titânio. Osseointegração. ---Abstract: Dentistry is increasingly seeking dental rehabilitation methods that are less traumatic and effective aesthetically and visually. In this regard, dental implants have been increasingly developed to ensure patient satisfaction, through technological advances such as the Titanium Nano-surface. Thus, this study aims to address the issue of titanium implant surfaces in terms of their ability to stimulate bone formation, as it is a technique that reduces the time of osseointegration and, consequently, the duration of the process and patient recovery. To this end, a bibliographic review was carried out in electronic databases on the subject, which could prove the reduction of time in the work of the dentistry professional and a better quality regarding dental implants, through the analysis of three national brands to prove its effectiveness. Keywords: Dental implant. Titanium Nano-surface. Osseointegration.

Antecedents of similarity perception for store-branded lookalikes

PurposeThis paper aims to identify the key antecedences contributing consumer similarity perception toward store branded lookalikes (SBLs), testing to what extent each of the antecedences influences the overall similarity perception.Design/methodology/approachTwo empirical studies were conducted. Study 1 was an online experiment to test the relative importance of packaging features on similarity judgment of SBLs. Study 2 examined the impacts of consumer characteristics and store related elements on similarity perception through a Qualtrics web-based questionnaire covering seven product categories.FindingsThis research yields two key findings. First of all, it revealed that all three packaging attributes studied (i.e. size and shape, image and color) exert positive influence on similarity judgment of SBLs, among which color shows the most significant importance, followed by size and shape, and then color. Then, it showed that brand loyalty fully mediated the effect of brand familiarity on consumers' similarity perception, giving that no direct effect was found from brand familiarity to similarity perception but consumers' brand loyalty increased as they become more familiar with the NBs. As consumers become more loyal to the brands, they would perceive the SBLs to be less similar to imitated national brands.Practical implicationsThis research confirmed the significance of proper manipulation of packaging design, either to the SBLs or to the imitated NBs. It also reveals the critical role of gaining high familiarity and strong loyalty for the NB manufacturers. For retailers, the research highlights the need to maintain a better store image in order to take advantage of SBLs to help with marketing competition.Originality/valueThis research contributes new knowledge on the lookalike phenomenon by uncovering the prerequisites that cause similarity perception between two products.

Development of a National Rating System to Evaluate the Brand Attraction of Sewing and Knitting Enterprises

The article proposes a mechanism for creating a national rating system aimed at including local brands in the international ranking of global brands in order to assess the brand attractiveness of sewing and knitting companies operating in Uzbekistan. It recommends the methodology of rating of national and global brands, the main segments of the analysis of national brands, the direction of development of the rating system, the rating criteria for the evaluation of local brands and the sources of their identification. The development of a national rating system for brand evaluation will lead to the formation of a healthy competitive environment for local brands, protection of consumers from substandard products, the creation of an integrated system between enterprises and consumers.

US brand still strong but needs to show effectiveness

Significance Recent events have complicated the military and diplomatic elements of this task, but the wider 'Brand America' which Biden wants to restore -- one that shows democratic institutions solving the challenges of the 21st century more effectively than authoritarian regimes -- also needs attention. Impacts National brands cannot be managed as tightly as corporate brands but still need to embody and project a set of values and purposes. The shifting balance between long-standing US trends of internationalism and isolationism will be closely watched abroad. The prospect of a future president treating geopolitics as a zero-sum great power contest risks deep damage to 'Brand America'. Reduced margins of US pre-eminence will require Washington to adopt a more collaborative style of international leadership.

Investigating the healthiness of food products on promotion: market brands and own brands

PurposeThe purpose of this study is to investigate the proportionality of market brand (MB) foods versus supermarket own brand (OB) foods sold on promotion and to compare their healthiness.Design/methodology/approachAn existing dataset containing nutritional information about a variety of foods on promotion (n = 6,776) from 48 stores across 8 retail chains in Northern Ireland (NI) was reanalysed. Product healthiness was measured using a score aligned to the Food Standards Agency's Front of Pack nutrient labelling system. MBs and OBs were considered as a whole and in their respective subsets–international/national and regional MBs, and premium, mid-market and value tiered OBs.FindingsResults found a balance in favour of health (52.4% amber/green versus 47.6% red) across retailers' promotions in NI. Further, OB products were often found to be superior to MBs with regards to overall healthfulness, and regional brands were found to be less healthy than international/national brands.Research limitations/implicationsFindings rationale further retail research to compare nutritionally OB and MB product types, and further consumer research regarding important attributes of OBs.Practical implicationsRetailers should communicate the comparative healthiness of their OBs in comparison to MB alternatives, in addition to communicating comparative price savings. There is opportunity for retailers to increase visibility of mid-market and value OB tiers, and for regional MBs to improve the nutritional profile of products in line with the consumer trend for health.Originality/valueThis study provides a contribution by using data on OBs and MBs on promotion, and by investigating the nutritional differences between different tiers of OB and MB products.

EXPRESS: Households under Economic Change: How Micro- and Macroeconomic Conditions Shape Grocery Shopping Behavior

Economic conditions may significantly affect households' shopping behavior and, by extension, retailers' and manufacturers' firm performance. By explicitly distinguishing between two basic types of economic conditions—micro conditions in terms of households' personal income and macro conditions in terms of the business cycle—this study analyzes how households adjust their grocery shopping behavior. The authors observe more than 5,000 households over eight years and analyze shopping outcomes in terms of what, where, and how much they shop and spend. Results show that micro and macro conditions substantially influence shopping outcomes, but in very different ways. Microeconomic changes lead households to adjust primarily their overall purchase volume—that is, after losing income, households buy fewer products and spend less in total. In contrast, macroeconomic changes cause pronounced structural shifts in households' shopping basket allocation and spending behavior. Specifically, during contractions, households shift purchases toward private labels while also buying and consequently spending more than during expansions. During expansions, however, households increasingly purchase national brands but keep their total spending constant. The authors discuss psychological and sociological mechanisms that can explain the differential effects of micro and macro conditions on shopping behavior and develop important diagnostic and normative implications for retailers and manufacturers.

Strategic Competition Between Private Labels and National Brands in a Vertically Linked Market

Over the past decades, the rapid emergence of private labels (PL) has created stiff competition for many established manufacturers of national brands (NB). Retailers are using PL products as a competitive weapon against NB. The present study develops and tests different theoretical models of competition under different retailer-manufacturer production arrangements for private labels using the Non-Nested Model Comparison (NNMC) approach and their impact on the pricing strategies of PLs and NBs in the Canadian retail market. The theoretical model shows that a retailer earns the highest profit when it behaves as a leader and makes the least profit when it behaves as a follower; a similar relationship holds for the NB manufacturer under different PL production arrangements. The total industry profit is the highest when the retailer and NB manufacturer behaves in a Bertrand Nash manner. Empirical results of the study show no consistent pattern of competitive interaction under various production arrangements of PL products.
