Summary
Orthodontists in Switzerland prefer palatal implants for maxillary distalization using temporary anchorage devices (TADs). TAD insertion sites varied more in the sagittal dimension than the transversal dimension.
Area of Science:
- Orthodontics
- Dental Implantology
- Maxillofacial Surgery
Background:
- Survey on orthodontists' treatment plan preferences in Switzerland.
- Focus on mechanics and characteristics of temporary anchorage device (TAD) application.
- Utilized a single borderline orthodontic case for evaluation.
Purpose of the Study:
- To gather information on treatment plan preferences for a complex orthodontic case.
- To understand the preferred mechanics and characteristics of temporary anchorage device (TAD) application.
- To analyze orthodontists' choices regarding TAD usage and surgical interventions.
Main Methods:
- Structured questionnaire distributed to Swiss orthodontists.
- Case presentation: adult female with Class II/2 malocclusion, deep bite, and maxillary crowding.
- Inclusion of general and case-specific questions on fixed appliance and TAD usage.
Main Results:
- High response rate (24.4%) with 96.3% opting for comprehensive treatment.
- Distalization using TADs was favored by 75.1% for maxillary arch.
- Palatal implants were the most popular TAD choice (70.6%), followed by mini-screws (22.4%).
- TAD insertion site variation was greater in the sagittal than transversal dimension.
Conclusions:
- Distalization using palatal implants or mini-screws emerged as the most popular treatment strategies.
- Orthodontists' preferred TAD insertion sites demonstrated significant variability, particularly in the sagittal plane.
- The study highlights diverse approaches to managing complex malocclusions with TADs.
