Summary
Maxillary intrusion in adults significantly reduces lip protrusion and the gap between lips, improving lip closure. Soft tissue profile changes were assessed using cephalograms and Holdaway
Area of Science:
- Orthodontics
- Dentofacial Orthopedics
- Cephalometric Analysis
Background:
- Anterior maxillary intrusion is an orthodontic procedure used to correct vertical discrepancies.
- Understanding soft tissue profile changes is crucial for predicting aesthetic outcomes.
- Limited data exists on the specific soft tissue adaptations following anterior maxillary intrusion in adults.
Purpose of the Study:
- To evaluate the adaptation of the soft tissue profile after anterior maxillary intrusion.
- To assess changes in lip protrusion and interlabial gap post-treatment.
Main Methods:
- Retrospective cephalometric analysis of ten adult patients.
- Preoperative and 6-month postoperative lateral cephalograms were compared.
- Holdaway's soft tissue analysis method was employed for profile evaluation.
Main Results:
- Significant reduction in lip protrusion was observed postoperatively.
- A significant decrease in the interlabial gap was noted.
- Acceptable lip competency was achieved in the majority of patients.
Conclusions:
- Anterior maxillary intrusion leads to favorable soft tissue profile changes in adults.
- Reduced lip protrusion and interlabial distance contribute to improved lip competence.
- Other contributing factors should be considered for optimal soft tissue results.
