Clear Aligners and Dental Implants: Protocol, Timing and Clinical Cases

The combination of clear aligner orthodontics and dental implantology is increasingly common in modern practices. These two disciplines complement each other remarkably: orthodontics prepares the ground for optimal implant placement, and the implant fills the gap left by a missing tooth that orthodontics alone cannot recreate. Here is the complete protocol, step by step.

When a tooth has been absent for a long time — whether extracted, accidentally lost or congenitally missing (agenesis) — adjacent and opposing teeth tend to drift spontaneously to fill the space. These migrations create insufficient space for an implant, atrophied alveolar bone and an unbalanced occlusion. Prior orthodontics recreates the ideal space, aligns the bone and prepares the site for an anatomically and aesthetically optimal implant.

Yes — clear aligners are fully compatible with already-placed implants. Unlike natural teeth, osseointegrated implants are ankylosed in the bone: they do not move under orthodontic forces. This means the implant serves as a fixed anchorage point during treatment, which can sometimes be strategically used by the practitioner to facilitate certain movements of adjacent teeth.

This is the central question of any implant-orthodontic planning. The answer depends on each patient's clinical situation:

• Orthodontics THEN implant (most common sequence): aligners reposition adjacent teeth to create the ideal space, then the implant is placed once teeth are in their final position. Retention maintains the space during the implant phase.
• Implant THEN orthodontics: if the implant is already in place and osseointegrated, aligners can be carried out around it — the implant will not move. This sequence is acceptable if the space was sufficient from the outset.
• Simultaneous (rare): in some complex cases, a temporary crown on the implant is used during orthodontic treatment, replaced by the definitive crown at the end of treatment.

Agenesis of the upper lateral incisor (congenital absence of tooth 12 or 22) is one of the most common cases combining aligners and implants. The standard Infinity Aligner protocol for this case is as follows:

• Phase 1 — Full assessment: panoramic X-ray, cone beam (CBCT) to evaluate available bone volume, digital impression.
• Phase 2 — Aligner orthodontics (4 to 12 months): opening or maintaining the space of the missing lateral, closing other spaces, general arch alignment.
• Phase 3 — Retention with space maintainer: a retainer tray maintains the precise space during the surgical phase.
• Phase 4 — Implant placement and osseointegration (3 to 6 months waiting period).
• Phase 5 — Implant crown: the crown is shaped to perfectly mimic a natural lateral incisor.

• Easier hygiene around implants: removable trays allow optimal cleaning of the implant site (dental floss, interdental brush, irrigator)
• No direct mechanical stress on the implant crown
• Aesthetics preserved throughout the entire pre-implant treatment period
• Simple modification of the tray if the implant treatment plan evolves

The combination of clear aligners and dental implants represents one of the most sophisticated and rewarding approaches in restorative dentistry today. It requires rigorous multidisciplinary planning, close communication between the orthodontist and implantologist, and regular patient follow-up. Certified Infinity Aligner dentists are trained to integrate this implant dimension into their orthodontic planning. Book an appointment for a comprehensive assessment of your situation.
