In the 1882 edition of Codman and Shurtleff's catalogue, the chair is referred to as "showing great originality,... all cranks are dispensed with and levers substituted for them." The chair was raised by a foot lever ("requires very little effort, and occupies but 8 seconds") and lowered by another lever ("sinks rapidly and noiselessly"). [2] Other levers allowed the chair to rotate ("through the whole circle") and rock back and forth. In addition, minor movements were possible, such as the raising or lowering of the back and headrest, slight rocking of the seat ("to prevent the patient form sliding forward"), footstool length and height adjustment, and the small of the back support (which converted into "a capital child's seat"). The upholstery could be ordered in either green or garnet plush fabric or in leather. The price was $177. [1]
Improvements in the 1899 model enabled a patient to lie in a horizontal position, and included a spittoon. [3]

The Ford Model T is an automobile that was produced by the Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. It was mainly designed by an American and two Hungarian engineers. The Model T was colloquially known as the "Tin Lizzie", "Leaping Lena" or "flivver".
A chair is a type of seat, typically designed for one person and consisting of one or more legs, a flat or slightly angled seat and a back-rest. They may be made of wood, metal, or synthetic materials, and may be padded or upholstered in various colors and fabrics.
A stretcher, gurney, litter, or pram is an apparatus used for moving patients who require medical care. A basic type must be carried by two or more people. A wheeled stretcher is often equipped with variable height frames, wheels, tracks, or skids. Stretchers are primarily used in acute out-of-hospital care situations by emergency medical services (EMS), military, and search and rescue personnel. In medical forensics the right arm of a corpse is left hanging off the stretcher to let paramedics know it is not a wounded patient. They are also used to hold prisoners during lethal injections in the United States.
Dental braces are devices used in orthodontics that align and straighten teeth and help position them with regard to a person's bite, while also aiming to improve dental health. They are often used to correct underbites, as well as malocclusions, overbites, open bites, gaps, deep bites, cross bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws.
A bridge is a fixed dental restoration used to replace one or more missing teeth by joining an artificial tooth definitively to adjacent teeth or dental implants.

In orthodontics, a malocclusion is a misalignment or incorrect relation between the teeth of the upper and lower dental arches when they approach each other as the jaws close. The English-language term dates from 1864; Edward Angle (1855-1930), the "father of modern orthodontics", popularised it. The word "malocclusion" derives from occlusion, and refers to the manner in which opposing teeth meet.
A dental extraction is the removal of teeth from the dental alveolus (socket) in the alveolar bone. Extractions are performed for a wide variety of reasons, but most commonly to remove teeth which have become unrestorable through tooth decay, periodontal disease, or dental trauma, especially when they are associated with toothache. Sometimes impacted wisdom teeth cause recurrent infections of the gum (pericoronitis), and may be removed when other conservative treatments have failed. In orthodontics, if the teeth are crowded, healthy teeth may be extracted to create space so the rest of the teeth can be straightened.
A recliner is an armchair or sofa that reclines when the occupant lowers the chair's back and raises its front. It has a backrest that can be tilted back, and often a footrest that may be extended by means of a lever on the side of the chair, or may extend automatically when the back is reclined.
Orthodontic technology is a specialty of dental technology that is concerned with the design and fabrication of dental appliances for the treatment of malocclusions, which may be a result of tooth irregularity, disproportionate jaw relationships, or both.
Dental fear, or dentophobia, is a normal emotional reaction to one or more specific threatening stimuli in the dental situation. However, dental anxiety is indicative of a state of apprehension that something dreadful is going to happen in relation to dental treatment, and it is usually coupled with a sense of losing control. Similarly, dental phobia denotes a severe type of dental anxiety, and is characterised by marked and persistent anxiety in relation to either clearly discernible situations or objects or to the dental setting in general. The term ‘dental fear and anxiety’ (DFA) is often used to refer to strong negative feelings associated with dental treatment among children, adolescents and adults, whether or not the criteria for a diagnosis of dental phobia are met. Dental phobia can include fear of dental procedures, dental environment or setting, fear of dental instruments or fear of the dentist as a person. People with dental phobia often avoid the dentist and neglect oral health, which may lead to painful dental problems and ultimately force a visit to the dentist. The emergency nature of this appointment may serve to worsen the phobia. This phenomenon may also be called the cycle of dental fear. Dental anxiety typically starts in childhood. There is the potential for this to place strains on relationships and negatively impact on employment.
