Mesial space closure is an attractive method for resolving malocclusions associated with agenesis of the maxillary lateral incisors, because it avoids prosthetic implants. Key factors for success are anchorage control, detailed finishing and interdisciplinary cooperation with the restorative dentist.

Mesial sliders secured by two splinted palatal miniscrews, are efficient non-compliance appliances that enable fast and secure space closure by protraction of an entire maxillary dentition.
