The Initial Challenge: A Deep Overbite and Upper Crowding
The patient first presented to our clinic alongside his mother (who had travelled from Iceland) seeking a discreet solution to correct his deep overbite and upper tooth alignment without traditional fixed braces.
A comprehensive clinical assessment by Orthodontist Claire O’Sullivan revealed:
- Class II Division 2 Bite Discrepancy: A significant overjet (6mm) where the lower jaw naturally sat far behind the upper jaw, combined with a deep overbite.
- Upper Arch Crowding: Lack of space leading to overlapping upper front teeth.
- Unerupted Wisdom Teeth: Developing back teeth requiring long-term space management.
The Customised Treatment Programme
Our specialist team design-engineered a non-extraction plan using Invisalign Clear Aligners with Mandibular Advancement (MA). This specialized technology features precision-moulded “precision wings” on the aligners that gently guide the lower jaw forward in stages while simultaneously straightening the teeth.
[Invisalign Aligners] ➔ [Mandibular Advancement Wings] ➔ [DentalMonitoring AI Tracking] ➔ [Refinement] ➔ [Essix LUXE Retention]1. Invisalign MA & DentalMonitoring (2022 – 2024)
- Phased Advancement: The patient began active aligner wear in late 2022, transitioning through aligners every 7 to 10 days. By late 2023, he progressed into the Mandibular Advancement phase to bring the lower jaw into a ideal Class I relationship.
- Remote AI Tracking: To minimise unnecessary clinic visits around school commitments, the patient was provided with a DentalMonitoring (DM) scanbox. Using his smartphone, he submitted regular scans from home. When the software detected a minor tracking mismatch on a rotated lower premolar (tooth 35) in mid-2024, Dr Claire O'Sullivan paused treatment and took a precision refinement scan to keep his bite alignment perfectly on schedule.
2. Perfection & Completion (Late 2024 – Early 2025)
Following a brief refinement series using Class I aligner elastics to close minor bilateral open bites, the active aligner phase was completed in January 2025. Attachments were removed, bonded retainers were fitted behind the front teeth, and custom Essix retainers were delivered.
Real-World Post-Treatment Care: Managing Severe Bruxism (2025 – 2026)
Orthodontic success does not end when alignment is complete; protecting the teeth against real-world habits is essential.
In late 2025, the patient experienced heavy night-time teeth grinding (bruxism), causing his standard Essix retainers to crack and wear through at the canines. Recognising his high occlusal force, Dr Claire O’Sullivan developed a specialised dual-retention solution:
- Custom Upper Nightguard & Lower Essix: An upper hard nightguard was custom-fabricated by McDowells dental laboratory to absorb heavy bite forces, paired with a lower Essix retainer.
- Upgrading to Essix LUXE (July 2026): To prevent ongoing wear and recurring replacement costs, Dr Claire upgraded his retention setup to Essix LUXE—a high-durability, impact-resistant resin material designed specifically for heavy grinders.
The Final Result
The patient achieved an exceptional result: a completely corrected Class I bite, zero upper crowding, and an aesthetically balanced profile. Thanks to the proactive bruxism management and high-durability Essix LUXE retainers, his smile investment remains fully protected for the long term.
The Specialist Advantage: Correcting an overbite in a growing patient requires a specialist who understands jaw growth dynamics. By combining Invisalign Mandibular Advancement, AI remote monitoring, and heavy-duty lab-fabricated retainers, Dublin Orthodontist delivered a seamless, comfortable, and highly durable result.
