Lead Orthodontist:

Orthodontist at Tech Dental

BMDC Reg No: 8742 | 07 Years Experience

Patient Presentation

• Age: 22 Years
• Gender: Female
• Chief Complaint: The patient presented with significant dissatisfaction regarding her smile. She expressed self-consciousness due to “crooked” and overlapping front teeth and reported difficulty in flossing between tightly packed teeth. She desired a straight, confident smile without undergoing jaw surgery.

Clinical Examination & Diagnosis

A comprehensive orthodontic assessment, including digital scans, photographs, and radiographs (OPG and Lateral Cephalogram), revealed the following:

• Severe Crowding: Significant lack of space in both the upper and lower dental arches, causing the anterior teeth to overlap and rotate out of position.
• Narrow Arches: Both maxillary (upper) and mandibular (lower) arches were constricted.
• Ectopic Eruption: The upper canines (“eye teeth”) were positioned high and blocked out of the arch due to lack of space.
• Diagnosis: Angle’s Class I Malocclusion with severe bi-maxillary crowding and a non-consonant smile arc.

Treatment Objectives

• Resolve severe crowding and align all teeth into their proper positions.
• Expand the dental arches to create necessary space and broaden the smile.
• Correct rotated teeth and bring blocked-out canines into alignment.
• Achieve a stable, functional bite (occlusion).
• Improve overall facial aesthetics and smile symmetry.

Treatment Plan: Fixed Orthodontic Therapy (Traditional Braces)

Given the severity of the crowding and the need for significant bodily movement of roots, Fixed Metal Braces (MBT prescription) were recommended as the most efficient treatment modality. The plan involved non-extraction therapy, focusing on arch expansion to gain space.

Clinical Procedure Summary

The treatment spanned approximately 20 months:

• Bonding & Initial Alignment (Months 1-6): Brackets were bonded to the teeth. Light, flexible nickel-titanium wires were used to begin gently unraveling the crowding and rotating teeth.
• Arch Development & Leveling (Months 7-12): Stronger, rectangular wires were introduced to widen the arches and level the curve of the bite. Coil springs were used to create space for the blocked-out canines.
• Major Mechanics & Bite Correction (Months 13-17): Once all teeth were aligned, stainless steel wires and inter-maxillary elastics (rubber bands worn by the patient) were used to perfect the bite relationship between upper and lower teeth.
• Finishing & Detailing (Months 18-20): Minor adjustments were made to ensure the aesthetics of the smile were optimal.
• Debonding & Retention: Braces were removed. Fixed lingual retainers (bonded behind front teeth) and removable clear retainers were provided to prevent relapse.

Results and Outcome

The final results showed a dramatic transformation:

• Aesthetics: The crowding was completely resolved. The patient now possesses a wide, symmetrical, and highly aesthetic smile.
• Function: A stable Class I occlusion (ideal bite) was achieved, improving chewing function and enabling easier oral hygiene maintenance.
• Patient Satisfaction: The patient was thrilled with the outcome, reporting a significant boost in self-esteem and confidence.

Conclusion

This case exemplifies the transformative power of comprehensive orthodontic treatment. Despite severe crowding, Dr. Md. Ashraful Hashem Johny successfully utilized fixed appliances to achieve functional harmony and aesthetic excellence without the need for tooth extraction, delivering a life-changing smile at Tech Dental.
