Adolescent Crowding Treated with Self-Ligating Braces and IPR
This case demonstrates the treatment of an adolescent patient who presented with crowding in both dental arches, excessive overbite, excessive overjet, and a maxillary midline deviation to the right. Through the use of self-ligating braces, bite turbos, and interproximal reduction, the patient achieved proper alignment without the need for permanent tooth extractions. The treatment was completed in 16 months with stable results at four-month follow-up.
Patient Overview
The patient was an adolescent who presented for comprehensive orthodontic treatment. The primary concern was crowding affecting both the upper and lower dental arches, along with associated bite discrepancies that required correction to achieve proper dental alignment and function.
Chief Complaint
The patient presented with crowding as the primary concern. The patient's goal was to achieve proper alignment of the teeth and improve the appearance of the smile.
Diagnostic Findings
Clinical examination revealed crowding in both the upper and lower arches. The patient presented with excessive overbite and excessive overjet. Additionally, the maxillary midline was positioned to the right, creating an asymmetry that required correction. Jaw growth, facial development, and skeletal relationships were within normal limits and did not play a role in the treatment planning for this case.
Treatment Options Considered
Two primary treatment options were presented to the patient and parents: traditional braces or Invisalign clear aligner therapy. Both options were discussed as viable approaches to address the crowding, overbite, overjet, and midline discrepancy.
Selected Treatment Plan
After reviewing the available treatment options, the patient and parents chose to proceed with braces. This decision was based on their preference and comfort level with the treatment modality. The treatment plan was designed to address all diagnostic findings while avoiding the need for extraction of permanent teeth.
Procedures Performed
Self-ligating braces were bonded to both the upper and lower arches. Bite turbos were placed to open up the bite, creating the vertical space necessary to correct the excessive overbite. Interproximal reduction was performed strategically to create the space needed to resolve the crowding without requiring extraction of permanent teeth.
During the treatment planning phase, the patient and parents were informed that due to the shape of the teeth, there was a possibility of developing triangular spaces between the maxillary incisors. However, by the end of treatment, no such triangular spaces had developed, which was a positive outcome for the case.
The total active treatment time was 16 months, during which the patient progressed through the planned phases of bite opening, space creation through interproximal reduction, and final alignment and detailing.
Materials and Technologies Used
The case utilized self-ligating braces, which allow for reduced friction and potentially more efficient tooth movement compared to traditional ligated brackets. Two bite turbos were placed to facilitate the correction of the excessive overbite. Interproximal reduction was performed as a conservative space-gaining technique to avoid the need for permanent tooth extractions.
Clinical Challenges
No significant challenges or complexities were encountered during the course of treatment. The case progressed as planned, and the patient cooperated well throughout the treatment process.
Final Outcome
Treatment was successfully completed in 16 months. The patient's crowding was fully resolved in both arches, the excessive overbite was corrected, the overjet was normalized, and the teeth were properly aligned. The maxillary midline discrepancy was addressed, and the anticipated triangular spaces between the maxillary incisors did not develop.
At the four-month follow-up appointment, the results remained stable. The patient maintained proper alignment, and the smile continued to meet the treatment goals that had been established at the beginning of the case.
Clinical Lesson for Other Dentists
This case demonstrates that comprehensive orthodontic treatment in adolescent patients with moderate crowding can be successfully completed without permanent tooth extractions when interproximal reduction is used strategically. The use of bite turbos to open the bite prior to alignment allowed for correction of the excessive overbite while creating the necessary space for tooth movement.
Self-ligating braces provided an efficient means of tooth movement throughout the treatment process. Importantly, open communication with the patient and parents about potential outcomes, such as the possibility of triangular spaces, helps manage expectations and builds trust even when those concerns do not materialize.
The case also reinforces the value of allowing patients to participate in treatment modality selection. When patients and parents are involved in the decision between treatment options such as braces and clear aligners, compliance and satisfaction tend to improve.

Frequently Asked Questions
What is interproximal reduction and why is it used in orthodontic treatment?
Interproximal reduction, also known as IPR, is a technique where small amounts of enamel are carefully removed between teeth to create space. In this case, it was used to address crowding and allowed the patient to avoid having permanent teeth extracted while still achieving proper alignment.
What are bite turbos and how do they help correct an overbite?
Bite turbos are small buildup materials placed on the biting surfaces of teeth, typically on the back teeth or behind the front teeth. They temporarily open the bite by preventing the back teeth from fully coming together, which allows the front teeth to move more freely and helps correct an excessive overbite.
What are self-ligating braces?
Self-ligating braces are a type of orthodontic bracket that has a built-in mechanism to hold the archwire, rather than using elastic or metal ties. This design can reduce friction during tooth movement and may make adjustments more comfortable and efficient.
How long do I need to wear retainers after braces are removed?
In this case, the patient was instructed to wear clear retainers at nighttime following the completion of treatment. Nighttime retainer wear is typically recommended long-term to maintain the results achieved during orthodontic treatment and prevent teeth from shifting back to their original positions.
Can crowding be treated without removing permanent teeth?
Yes, in many cases crowding can be successfully treated without extracting permanent teeth. Techniques such as interproximal reduction, arch expansion, and proper use of appliances like bite turbos can create the necessary space to align teeth. The decision depends on the severity of crowding and the specific characteristics of each case.
