TK · Mixed Dentition Eruption Guidance Appliance
For the transition from primary to permanent teeth. Dental guiding grooves and positioning features assist permanent incisor eruption, early alignment and coordination of the dental arch and tooth positions.

Design & structure
Designed around permanent tooth replacement and eruption during mixed dentition. It combines directional guidance during eruption with alignment guidance for newly erupted teeth, providing dental seating and guidance.
Clinical use & follow-up
When retained teeth, substantial space deficiency, ectopic eruption or impaction is present, identify the cause first and establish an appropriate management plan.
Sizes & selection
| Model / size | Reference age / selection |
|---|---|
| TK-M · Medium | 6–8 years |
| TK-L · Large | 8–10 years |
Select according to the actual tooth-replacement stage, arch size and permanent tooth eruption, rather than age alone.
Reference ages are selection guides, not a treatment prescription. Final selection, wear and review follow clinical assessment and the applicable product instructions.
