Summary
Zygomatic implants enabled significant maxillary advancement in a patient with cleft lip and palate, correcting Class III malocclusion. This innovative approach improved facial profile and stability, avoiding common orthodontic complications.
Area of Science:
- Orthodontics
- Craniofacial Surgery
- Dental Implantology
Background:
- Class III malocclusion in cleft lip and palate patients often results from maxillary growth retardation.
- Traditional facemask therapy can have limitations in achieving predictable maxillary advancement.
Observation:
- Zygomatic implants were placed in a 12-year-old female with cleft lip and palate and Class III malocclusion.
- Elastic traction was applied from a facemask to the zygomatic implants for 8 months.
Findings:
- The maxilla moved 4 mm downward and forward, with anterior rotation.
- Mandibular opening increased by 2 degrees (SN-mandibular plane angle).
- Nasion to menton distance increased by 9 mm, improving infraorbital fullness and correcting prognathism.
Implications:
- Zygomatic implant-anchored facemask therapy offers a stable and effective method for maxillary advancement in cleft patients.
- This technique can improve midface aesthetics and potentially avoid secondary dental changes associated with conventional methods.
- Further research can explore long-term stability and broader applications in treating complex craniofacial anomalies.
