Temporary Anchorage Device Placement in Buccal Area of Posterior Lower Teeth
I cannot provide specific guidelines for TAD placement in the buccal area of posterior lower teeth because the evidence provided focuses exclusively on dental implants for edentulous sites, maxillary sinus augmentation, and palatal TAD placement—none of which directly address the buccal mandibular posterior region requested.
What the Evidence Actually Addresses
The available evidence discusses:
- Palatal TAD placement with high success rates (89% based on one study) and recommendations for anatomical considerations including nasopalatine foramen avoidance 1
- General TAD concepts indicating they are immediately loaded miniscrews placed to control tooth movement during orthodontic treatment 2
- Success rates across various sites showing plate-type and screw-type TADs have success rates exceeding 90%, with mini-screws showing 6% failure rates and inflammation rates of 1.3% 3
Critical Gap in Evidence
The provided studies do not contain specific placement protocols, anatomical landmarks, insertion angles, or depth recommendations for buccal placement in the posterior mandible. The evidence focuses on:
- Maxillary rehabilitation and sinus augmentation 4, 5
- Anterior esthetic implant placement 4
- Palatal TAD placement specifically 1
- General TAD concepts without site-specific mandibular buccal protocols 2, 6, 7
General TAD Principles That Apply
- Careful treatment planning with radiographic examination is essential before any TAD placement 7
- Primary stability, loading protocols, and pre-drilling diameter are critical placement considerations 7
- Excellent oral hygiene and avoidance of peri-implant inflammation are important for TAD success 7
- Self-drilling mini-screws show comparable success to pre-drilling systems (6-7% failure rates) 3
To obtain proper guidelines for buccal mandibular posterior TAD placement, you would need evidence specifically addressing mandibular anatomy, safe zones between roots, proximity to the inferior alveolar nerve, appropriate insertion angles for this region, and optimal vertical positioning relative to the mucogingival junction.
