Crowns
A crown is a tooth shaped cap that is put on over the tooth to restore the size and the strength of that tooth. When the crown is cemented into place it appears as the original tooth above the gum line. Crowns are great options for those weak teeth that sometimes we have no control over. Most crowns require two visits. The first visit the dentist will prepare the tooth and make the temporary. On the second visit, the patient receives the crown for fitting. For the all porcelain crowns, depending on the technology in the office, it takes one day. In that one day the tooth is prepared, and with a special machine, the crown can be made in the office. Therefore, there is no need for a temporary. There are many reasons a crown may be needed. One reason is to protect a weak tooth, possibly from decay. Another reason is to restore a broken tooth. Also they are needed to cover a tooth with a large filling, to hold a bridge in place, to cover discolored teeth, and to cover an implant. Along with the various needs for a crown, there are a variety of types. These permanent crowns can be all metal, porcelain-fused-to metal, all resin, or all ceramic. The metal crowns are composed of gold alloy, other alloys, or a base-metal alloy. For this type of crown, less tooth structure needs to be removed and the wearing of the opposing teeth is kept to a minimum. This type of crown probably lasts the longest in terms of wearing down because they rarely chip or break. The main reason this type is not chosen as much anymore is because of the esthetics. Otherwise, it is a good choice for out of sight molars. Porcelain-fused-to-metal crowns can be matched to your other teeth but the opposing teeth receive more wear than the all metal and resin crowns. This crown can be a good choice for the front or back teeth. One thing to consider is that the metal lining can show at the gum line and even more so if your gums recede, so it may not be a good choice for the front teeth. All resin crowns are the least expensive, because they wear down more and are more prone to fractures. All ceramic or all porcelain crowns provide the best esthetics than any other crown type. They are not as strong as porcelain-fused-to-metal and they wear opposing teeth down more than metal or resin crowns. These crowns are a good choice for the front or back teeth. I have seen lots of crown procedures performed in the dental office, but I saw all ceramic or all porcelain ones. I was curious to see what other options were out there for my patients. I have learned more about what types of crowns are available. Also, I learned specific qualities about each of the types. Along with qualities, I also learned more about esthetics, by learning which crowns should go on which teeth. Clearly, some are better than others, but for some patients it comes down to the price because maybe they don’t have a lot of money. In my career it is important to know the different types of crowns, so when a patient has questions I can give them more information. It is also important to know the quality of each crown, so I can meet the patient’s needs specifically.

Restorative Dentistry Research Paper

...veneers may be the best choice to restore your smile! Veneers are porcelain shells that are placed on the front of your teeth to restore your smile to its former beauty. After having dental veneers placed, you’ll be supremely confident in your smile! Fillings Fillings are materials that fill a space or cavity in the tooth. Common filling materials are silver amalgam, composite resin, glass ionomer, ceramic, and precious metals. At Clear Lake Dental Care, we use tooth-colored, mercury-free fillings as healthier and natural-looking alternatives to amalgam. Inlays/Onlays Inlays and onlays are special types of fillings that are used if a tooth is too weak to support a regular filling but is not yet a candidate for a full-coverage dental crown. These indirect fillings are designed in the laboratory in advance to fit the tooth structure perfectly. Inlays are placed within the center of the tooth, while onlays can cover the entire chewing surface....

...not clearly state the “competitive prices” that Macklin would pay to Canadian Closures. Also, the prices of the supplies listed in the contract were a few years old. As no meetings were scheduled with the board of directors with the specific agenda of discussing problems ailing the company, no major decisions were taken to resolve the problems. Three plants, out of the total ten, registered the bulk of shipment rejections. An attempt at understanding and resolving the problem by visiting these plants failed miserably. Macklin’s senior management refused to make any further investments in the joint venture. Rumors were rife that they were planning to replace crown suppliers. Canadian Closures Inc. was performing below industry standards with losses of $350,000 on sales of $10.2 million. Claims regarding the 75 million crowns were worth over $350,000. Recognizing this claim would mean sacrificing the company’s profits, however rejecting Macklin’s request would antagonize the venture’s only client....

...* The moves by both suppliers and customers of can makers to integrate into can manufacturing themselves had profoundly redefined the metal can industry since John Connelly’s arrival. * analysts saw little growth potential for metal cans in the 1990s * Industry observers forecast plastics as the growth segment for containers. By 1983, two-piece cans dominated the beverage industry where they were the can of choice for beer and soft drink makers. Of the 120 billion cans produced in 1989, 80% were two-piece cans. While aluminum companies developed the original technology for the two-piece can, steel companies ultimately followed suit with a thin-walled steel version. * The number of aluminum cans produced increased by almost 200% during the period 1980–1989, reaching a high of 85 billion, while steel can production dropped by 22% to 35 billion for the same period * Since the can constituted about 45% of the total cost of a packaged beverage, soft drink bottlers and brewers usually maintained relationships with more than one can supplier. Poor service and uncompetitive prices could be punished by cuts in order size. * Many large brewers moved to hold can costs down by developing their own manufacturing capability.4. By the end of the 1980s, the beer industry had the capacity to supply about 55% of its beverage can needs. Captive manufacturing was not widespread in the soft drink industry, where many small bottlers and franchise operations were generally more dispersed...

...Crown Cork & Seal in 1989 Teaching Note I introduce the class by remarking that John Connelly ran Crown Cork & Seal for over 30 years and followed essentially the same strategy for the entire period. The total return to shareholders over the 32-year period was just under 20% compounded. Now that Connelly has stepped down as CEO and given control to William Avery, is it finally time for a change? I begin by asking what are the key strategic issues facing Avery in the summer of 1989. Question 1. What are the key strategic issues that Avery needs to consider? What strategic options are open to him? Here I just want to develop the list and save the analysis of the issues until the end of class. The list of issues should include some of the following: (1) The old Continental Can is apparently for sale either in whole or in part. Should Avery consider bidding on some or all of the business? (2) Metal containers are very slow-growth and plastics is forecast to make significant inroads. Should Avery consider entering plastics? If so, in what segments, and should they build their capability or acquire someone? Who? (3) Expand the product line to a full line of metal containers, not so focused on beverage and aerosol? (4) Diversify into other packaging materials and product categories? (5) Diversify into other less-related businesses? (6) Exit, or sell the business? How should we go about addressing these issues? Presumably we should analyze the appropriateness...

Between the red riding hoods, Angels, Cheechs, Chongs, Hard Core Swat Cops, Princess Peaches, Marios, Luigis, Unicorns, Devils, Cats, Vampires, and Indian Chiefs, I would have no idea whose was the best but, luckily for me Jesus showed up to my party! Jesus is a symbol of all things holy; he can bless your spirits and your wine all while kicking your ass at beer pong. He can choose whatever kind of attitude to have towards your questions about life. The Jesus at my party his name is Chris, friend of a friend who grew out his beard all year to play the role he was born to play; and that role of course was “Party God Jesus”. Not only did he absolve my guests and I of all our sins but, personally placed his crown of thorns a top this Heathen Pocahontas’ head curing me of whatever ailments may come to me in the future. Then handing me a cigarette he said “no cancer for you my child”. Now for the worst of the best this goes to the sluts that showed up at my party.

...Spain During Ancient Times or Dates of Antiquity During ancient times or dates of antiquity Spain was under the Roman Empire. It was called Hispania, to it were born Roman emperors Trojan and Theodosius I and the philosopher Seneca. The Roman Empire (Latin: Imperium Romanum) was the post-Republican period of the ancient Roman civilization, characterized by an autocratic form of government and large territorial holdings in Europe and around the Mediterranean. Spain During the Middle Ages 5th to 8th Century Rulers: Alaric I (Alareiks in the original Gothic) was likely born about 370 on an island named Peuce (the Fir) at the mouth of the Danube in present day Romania. King of the Visigoths from 395–410, Alaric was the first Germanic leader to take the city of Rome. Having originally desired to settle his people in the Roman Empire, he finally sacked the city, marking the decline of imperial power in the west. Euric, also known as Evaric, Erwig, or Eurico in Spanish and Portuguese (c. 415 – 484), Son of Theodoric I and the younger brother of Theodoric II and ruled as king of the Visigoths, with his capital at Toulouse, from 466 until his death in 484. He inherited a large portion of the Visigothic possessions in the Aquitaine region of Gaul, an area that had been under Visigothic control since 415. Over the decades the Visigoths had gradually expanded their holdings at the expense of the weak Roman government, advancing well into Hispania in the process. Alaric II, also...

Number Three

...Number Three The postmodern society is constantly changing. All the old things such as buildings are replaced with the impeccable modern ones. Just like the former English Teacher, Miss Coral who is caught between a rock and a hard place. Today people have to be perfect and everything we are occupied with must be done flawlessly. The author Anna Metcalfe emphasizes exactly this issue in the short story “Number Three”, where Miss Coral is trapped in a culture clash. She´s replaced with a so called “Real English Teacher” – the contemporary ideal person, Mr. James. Miss Coral is replaced with Mr. James who is supposed to be a better teacher than her. Her boss says he has done her a favour by making her an international hostess, in charge of an English teacher program. After all he could have chosen to fire her, “The director was keen that she should not take the redistribution of her skills as a sign of promotion (…) she has been withdrawn from teaching on grounds of incompetence”, (line 13-15). Throughout the short story “old” Miss Coral is equated with the Tianfu slum. She is replaced with Mr. James, who is modern and new. The old city is also replaced with something better and fresh, “The shanty town shacks of Tianfu, half flattened, are making way for settlement housing”, (line 19-20). The setting plays a major role in the short story as it refers to Miss Coral´s state of mind. The big polluted city has “flattened” Miss Coral and her career. The smog and dust in the city...

Assess the Significance of Spanish Rulers’ Desire for Religious Uniformity in the Expansion of Their Power 1474-1598

...in the expansion of their power 1474-1598 The Spanish expansion of power during the era of 1474-1598 can be clearly categorised into three separate periods, with each different ruler of Spain bringing with them a diverse train of thought in regard to expansion than their predecessor. Firstly, with Ferdinand and Isabella came the union of Iberia under one household, and in 1492 they succeeded in conquering Granada which is seen the first physical expansion of power during their reign, and this period. Granada was of key significance to the monarchs as, for Isabella, it provided a stronghold of Moorish tradition and beliefs, and for Ferdinand it gave his enemies in North Africa a gateway to Spain. so when the announcement came from the crown that it was to begin conquering Granada in 1481 it can be said that both Isabella and Ferdinand had different agendas and motives, however in 1481 Ferdinand was stated to say that he “wished to conquer that kingdom of Granada and expel from all Spain the enemies of the catholic faith and dedicate Spain to the service of God”. Also in a letter from the monarchs dated 1485 they state their intent to spread the catholic faith and remove the “unremitting menace” from the southern lands. Furthermore this source also goes to state that if Ferdinand and Isabella wished to simply expand physical power or gather treasure they would have done so already, assumingly from other areas, rather than a religious crusade. However it is suggestible that Ferdinand...
