Intro: History of anchorage
Orthodontic anchorage, defined as the ability to avoid unwanted tooth movements that is provided by other teeth, by the palate, head, or neck, or implants in bone¬¬¬¬ (1)
The fundamental of orthodontic anchorage is based on Newton's third law of motion which states that for every action there is an equal and opposite reaction. An understanding of this law is necessary to produce desired types of tooth movement and anchorage. (7)
Anchorage is composed of units of resistance. This may be a single tooth, a group of teeth, or any available anatomic areas. Together with the use of appliances, anchorage can be made to offer resistance to movement. (7)
It is generally accepted that unless an additional posterior force is

With such an anchorage preparation the direction of pull from the Class II elastics would be greater than 90° during function. Such a pull will further depress rather than elongate the terminal molars.
Third degree or total anchorage preparation was reserved for cases which had an ANB angle of more than or equal to 5° and the total discrepancy was 14- 20mm.
The anchorage preparation was such that all the molars and premolars were tipped distally with the distal marginal ridge of the second molar being located below the gum level.
Such anchorage preparation is usually not required nowadays. (3)
The edgewise bracket eliminated the sim-ple anchorage potential of the anterior teeth. Tweed and others applied differential anchor-age concepts with the edgewise appliance by using a series of archwires with tipback bends in the buccal segments—thereby enhancing anterior retraction as well as anchorage preservation
Tweed modified these tipping mechanics slightly for use in nonex-traction treatment. Tweed used tipback bends to facilitate anterior retraction by tipping teeth distally toward extraction sites.
A. Before extraction of bicuspids.
B. Initiation of retraction, with vertical loops to close
This is the process of placing a post into your jawbone. Eventually, implants will allow you to replace teeth you have lost, thus restoring the function and appearance of your teeth.
Tooth surfaces are referred to by various names in dentistry, including mesial, distal, buccal, and lingual. If you drew a midline t...

An orthodontist’s job is to identify the underlying problem of the teeth, identify the cause and proceed with the treatment based on his identifications. There are certain steps
Braces came about in the early 1800s, but humans were practicing orthodontics before Christ. David Evans, DDS, says that many mummified remains, with what researchers believe could have been an early attempt to close gaps in teeth, were discovered by archaeologist early in ancient history. He states, “These remains have a cord made from animal intestines (known as catgut) wrapped or run along the teeth in a very similar style to how modern orthodontists run orthodontic wire along the teeth in an effort to close off gaps.” The Surgeon Dentist, written by Pierre Fauchard, the father of modern dentistry, was published in 1728. His book gave birth to modern Orthodontics.

The Invisalign system is a treatment that focuses on correcting minor to moderate orthodontic issues. The treatment
Diagnostic tools will be used to develop a customized treatment plan for the patient. Device will be used to gently move the teeth into proper position. There are different types of devices that can be used to gently move the teeth into proper position the teeth alignment and these devices may be fixed or removable. Lingual braces are non-removable an example of removable devices are the invisalign system. The orthodontist will ensure that adequate and continual pressure is applied to the teeth regardless of the device.
Most people believe an orthodontist and a dentist have two extremely similar jobs all because they both work with the human mouth. This, however, is not entirely true. An orthodontist focuses on a patient's mouth, straightening teeth and even jaws when necessary. Orthodontists will always make sure that jaws are properly aligned before recommending braces. Depending on each patient, the number of years wearing braces can vary (“Become an Orthodontist”).
Dentistry as a profession over the years has evolved rapidly in light of new scientific evidence. Rapidly evolving science and technology have implemented changes within dentistry as evidenced by new standards and guidelines being produced by nationally recognised associations including National Institute for Health and Clinical Excellence (NICE), Faculty of General Dental Practice (FGDP) and Scottish Intercollegiate Guidelines Network (SIGN) in Scotland, in provision of new scientific evidence. The latest standards and guidelines produced, endorse everyday clinical practice through evidence based dentistry (REF). All dental professionals as part of continued professional development are expected to keep to date on relevant guidelines and knowledge related to their practice (REF). This is supported by the General Dental Council who state all clinicians must maintain their professional knowledge and competence throughout their working career (REF).
Healthcare is a necessity to sustain society. Dentistry is an area of healthcare that I feel extremely passionate about because access to proper dental care is limited, especially in the underserved communities. As an African American, I want to become a dentist and healthcare provider in the hopes of helping patients and adding to the diversification of the field. With a growing minority population in the United States, it has become apparent that there is a shortage of black dentists. This is problematic because underrepresented minorities are in great need of access to culturally connected dentists who understand their clinical needs as much as their lives and their challenges. I believe that when the profession includes a range of ethnicities
Picture yourself with a toothache or someone with poor hygiene and knowing you cannot do anything to change it without a dentist. A dentist is specialized individual that treats the diseases and conditions that affect the oral cavity.
It’s an accessory cusp usually located on the lingual surface of permanent or deciduous incisors.
This may be required in cases when the conventional root canal treatment is unable to save the tooth. It is a minor surgical procedure that involves the removal of the very tip of the tooth after which the gap is sealed. An apicoectomy also enables the endodontist to remove any infection or dead debris at the tip of the root. Once the canal is cleaned up and sealed, the risk of infection is very low. In some cases, the endodontist may use bone grafts or other implant techniques to assist with bone growth, especially in cases where the infection has left a big gap. In most cases, the tooth will be salvaged and normal function is
Modern face-bows and articulators are absolutely essential for producing consistently predictable outstanding aesthetic restorations, and they have become extremely accurate and easy to use. the use of new modern face bows made it possible to mount the dental casts of asymmetrical face to reproduce their clinical appearance. The mounted case meets the occlusal and functional demands of the dentist at the same time provides the dental operator with the correct horizontal and vertical orientation. This correct spatial orientation enables the dental operator to visualize and produce the highest-quality aesthetic restoration as possible for the patient comfort. The usage of the face bows facilitates the production of higher-quality
