Orthodontic treatments address all types of orthodontics issues that affect both oral health and the aesthetics of a smile. One common problem is Tooth Size-Arch Length Discrepancy (TSALD), or when the size of the teeth and the space in the dental arch don’t match. This misalignment can lead to crowding or excessive spacing, often due to either oversized teeth, an undersized arch, or occasionally both.
Understanding TSALD is important for effective treatment planning and outcomes. Orthodontists use various tooth models and diagnostic tools to assess TSALD, visualize teeth arrangement, and plan the right orthodontic solutions for each patient.
Tooth Size-Arch Length Discrepancy
TSALD is a complex teeth puzzle that requires sophisticated diagnostic tools. Traditionally, interarch tooth size and distance measurements were primarily done using plaster models and calipers. But these methods are time-consuming and labor-intensive requiring multiple steps to determine the space available and space required for treatment.
Today, orthodontists use advanced measurement tools such as 3D scanning and modeling. With scanners like the iTero, 3Shape R700T and software like Nemocast 3D, orthodontists can create precise digital representations of dental arches and perform complete analyses. And with medical imaging like Cone-Beam Computed Tomography (CBCT), orthodontists can use X-ray scans to evaluate teeth, gums, jaw and sinuses as well as create treatment plans and determine dental implants.
These steps are important because they help guide the choice of orthodontics whether braces, aligners or other treatments. Braces are a traditional option that gradually adjust the teeth to better fit the arch. Aligners are a more aesthetic and less invasive alternative, better for mild to moderate problems. In severe cases, additional interventions like tooth extraction or arch expansion might be needed.
