DANB's Maryland Orthodontic Assisting Expanded Functions - Why Exam Edge Sample Questions

In orthodontics, tooth movement occurs due to:





Correct Answer:
reshaping of the alveolar bone.


in orthodontics, the primary mechanism behind tooth movement is the reshaping of the alveolar bone, which is a process known scientifically as bone remodeling. this process is essential to understand why the correct answer is "reshaping of the alveolar bone" rather than other options provided like removal of teeth, restoration of teeth, or treatment of the gingiva.

orthodontic treatments, such as braces, apply continuous pressure to the teeth. this pressure is transmitted to the surrounding alveolar bone, which is the part of the jaw that holds the teeth in place. the force exerted by the braces initiates a biological response in the bone tissue, leading to the remodeling of the alveolar bone.

bone remodeling occurs in two phases: resorption and deposition. when pressure is applied to a tooth, the bone in the direction of the tooth movement starts to break down in a process called resorption. this is mediated by cells known as osteoclasts, which remove bone tissue. concurrently, on the opposite side of the tooth where tension is generated, new bone is formed by cells called osteoblasts in a process known as deposition.

this remodeling process is not instantaneous but occurs over time with the sustained application of orthodontic forces. the changes in the periodontal ligament and blood supply to the area also support this process. the periodontal ligament, which is a soft tissue that connects the tooth to the alveolar bone, helps in transmitting the forces from the tooth to the bone and plays a critical role in the remodeling process.

thus, the correct understanding of tooth movement in orthodontics is not about the simple mechanical movement of teeth through the bone but involves a complex biological process of bone remodeling. this process ensures that the tooth moves effectively into its new position and the bone adapts to support the tooth in its new location, stabilizing it for proper function. hence, the reshaping of the alveolar bone is crucial and is rightly identified as the reason for orthodontic tooth movement.

Glass ionomer cement is used to bond bands to teeth instead of zinc phosphate cements because:





Correct Answer:
it is stronger than zinc phosphate cements.


glass ionomer cement is generally chosen over zinc phosphate cements for bonding bands to teeth primarily due to its superior strength. this attribute is particularly significant when considering the forces exerted on the teeth and the bands by orthodontic appliances, such as headgear. the enhanced strength of glass ionomer cement ensures that the bands remain securely attached to the teeth throughout the treatment, even under the stress of external devices.

in addition to its strength, glass ionomer cement has other properties that make it more suitable than zinc phosphate cements for dental applications. for instance, glass ionomer releases fluoride, which can help in reducing the incidence of caries around the bands. this property is absent in zinc phosphate cements, making glass ionomer a more beneficial choice in terms of long-term dental health.

furthermore, glass ionomer cement adheres well to both enamel and dentin without requiring a separate bonding agent. this characteristic simplifies the clinical procedure as it eliminates steps in the bonding process, reducing the potential for error and saving time during dental procedures.

although zinc phosphate cement has been used historically for many dental applications, its usage has declined in favor of materials like glass ionomer that provide better mechanical properties, ease of use, and additional benefits such as fluoride release. while zinc phosphate cements are effective in some scenarios, their lower bond strength compared to glass ionomer can lead to a higher likelihood of band failure, especially in orthodontic treatments involving forceful mechanical devices.

in summary, glass ionomer cement is preferred over zinc phosphate cement for bonding bands to teeth due to its superior strength, ability to release fluoride, and better adhesion properties. these characteristics ensure a more reliable and effective treatment outcome, particularly important in orthodontic therapies involving additional mechanical stresses.
