Abstract

Background: Infrazygomatic crest (IZC) miniscrews are widely used as extra-alveolar temporary anchorage devices in orthodontics due to their biomechanical advantages and minimal dependence on patient compliance. Their success depends on multiple clinical and operator-related factors. Materials and methods: A crosssectional survey was conducted among 100 orthodontists using a validated 20-item questionnaire. The questionnaire assessed implant selection, insertion techniques, loading protocols, complications, and perceived success factors. Data were analysed using descriptive statistics. Results: Titanium miniscrews were preferred by 74.4% of respondents. Most clinicians selected 10–12 mm length (82.1%) and 2.0 mm diameter (82.1%). Selfdrilling technique (89.7%) and insertion angulation of 65–70° (76.9%) were commonly used. Immediate loading was preferred by 61.5% with forces of 150–250 g (68.4%). A success rate greater than 90% was reported by 72% of practitioners. Bone thickness, angulation, and oral hygiene were identified as key determinants of success. Conclusion: IZC miniscrews demonstrate high clinical success with consistent trends in clinical practice. Standardisation of placement and loading protocols may further enhance treatment predictability.
