Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients with palatally impacted maxillary canines on one side, with an angle of less than 45 degrees.
✕Probably not a fit
Patients with clefts, syndromes, previous orthodontic treatment, or canines with angles greater than 45 degrees will not benefit from this study.

What this trial studies
This clinical trial evaluates the effectiveness and patient experiences of two surgical techniques for treating palatally impacted maxillary canines. One technique involves a novel closed exposure method with additional bone removal, while the other is a conventional method without bone removal. The study aims to compare these techniques in terms of treatment effectiveness and the anchorage situation for incisors. Participants will receive either treatment and their experiences, particularly regarding pain and discomfort, will be assessed.
Why it matters
Potential benefit: If successful, this study could lead to more effective and comfortable treatment options for patients with impacted maxillary canines.
How similar studies have gone: While there have been studies on surgical exposure techniques, this specific comparison of a novel method versus a conventional method is relatively novel.
