Correction of Class I Malocclusion With Severe Crowding
A 27-year-old male patient presented with severe crowding, misaligned teeth, difficulty in maintaining proper cleaning and flossing, crossbites of mandibular canines, dark vestibule appearance, and displeasure at his overall smile and appearance. The clinician specifically selected ClearCorrect® aligners (Straumann, clearcorrect.com), a Straumann Group brand renowned for its thermoplastic rigidity and high trimline design, due to their ability to effectively meet the retention requirements of this case. The Unlimited case type was selected, which is ideal for comprehensive treatment, long-term retention, and minimizing unexpected expenses. Optimal results were achieved with the expansion of the buccal corridor and by placing occlusal bite ramps to open the bite and correct the anterior crossbite. For proper space maintenance, a bar was placed on tooth No. 19. The patient's total treatment plan included two phases: (1) 16 steps in 6 months that included the extraction of teeth Nos. 1, 16, 17, and 32, expansion of the buccal corridor, and placement of engagers on teeth Nos. 6, 7, 10, and 20; and (2) 18 steps completed over 9 months. Upon completion of treatment, crossbite issues were resolved, overall general oral health was improved, and the patient was pleased with the results. Full-time ClearCorrect retainers were created for both the maxillary and mandibular arches to be worn thereafter.
KEY TAKEAWAYS
With a high and flat trimline, ClearCorrect aligners have been scientifically proven to optimize force transmission for more accurate tooth movement and enhanced root control.*
ClearCorrect's industry-leading tri-layer material provides greater orthodontic control by combining two layers of resilient polymers with an elastomeric inner layer, resulting in gentle, consistent application of force.
Clinicians are offered the advantage of a wide variety of treatment options and the convenience of self-service upgrades, all accessible directly through the ClearCorrect Doctor Portal.
