Presenting Clinical Problem
A patient presented to Greenvale Dental House concerned about a noticeable space between the upper front teeth (a midline diastema).
- Significant spacing between the maxillary central incisors.
- Concern about the appearance of the anterior spacing.
- Assessment of periodontal (gum) health and tooth position.
- Evaluation of the bite and occlusal relationships for stability.
The primary objective was to reduce the anterior spacing while maintaining gum health and a stable bite.
Treatment Approach
Phase 1 — Orthodontic assessment and planning
- Comprehensive orthodontic records, including radiographs and photographs.
- Digital scanning to build a virtual treatment simulation.
- Assessment of the tooth movement required and an estimate of treatment duration.
- Discussion of the advantages and limitations of clear aligners.
- Consent covering the treatment and its retention requirements.
Phase 2 — Active aligner treatment
- Sequential clear aligner wear following the prescribed schedule (typically about 20–22 hours a day).
- Regular monitoring appointments to review tooth-movement progress.
- Tracking checks to confirm the teeth were following the predicted path.
- Mid-treatment refinement where required.
- A typical duration of several months, depending on complexity.
Phase 3 — Retention
- A fixed or removable retainer to hold the tooth positions.
- Instructions for long-term retainer wear.
- Discussion of the risk of relapse (the space reopening) without ongoing retention.
Clinical Outcome
Treatment involved sequential tooth movement over several months to reduce the anterior spacing. Digital planning helped visualise the predicted result, though actual movement can differ from the simulation depending on individual biological response.
Individual responses to orthodontic treatment vary. Clear aligners rely on excellent compliance and can cause temporary discomfort, and there is a small risk of root resorption. Spaces can reopen without lifelong retention, and treatment can take longer than first estimated. Results vary, and suitability for Invisalign needs to be confirmed at a clinical consultation.
Frequently Asked Questions
How long does Invisalign for a gap usually take?
Duration varies with the amount of movement needed, commonly ranging from around 6 to 18 months for moderate cases. Individual biological response affects how quickly teeth move, and some cases need additional refinement aligners beyond the first plan. Regular monitoring is essential.
What happens if the aligners are not worn as directed?
Wearing aligners for less than the prescribed 20–22 hours a day can compromise the result. Teeth may not track as planned, which can require re-planning or extend the treatment. Consistent wear is essential.
Will the gap stay closed afterwards?
Retention is needed indefinitely to hold the result. Even with retainers, some minor movement can occur over time, and stopping retainer wear commonly allows the space to reopen. The degree of relapse varies between individuals.
