Safe Filler Injection Techniques

From Dentistry Made Simple Dentistry Made Simple

An instructional manual focusing on safe and effective injection techniques for hyaluronic acid (HA) fillers in various facial areas, including the forehead, temples, nose, midface, glabellar region, and nasolabial folds. A central theme is the critical importance of anatomical knowledge and the use of Doppler ultrasound to detect arteries and avoid dangerous vascular complications, such as skin necrosis and blindness. The guide discusses specific considerations for each facial area, including the appropriate injection layer (e.g., subgaleal plane, supraperiosteal layer) and the necessary filler properties (e.g., cohesiveness, G' strength) for achieving optimal aesthetic results while minimizing risks. The excerpts also address filler properties, the role of hyaluronidase in managing complications, and techniques like the "ABC" methods for prevention, which emphasize aspiration, the use of big cannulas, and gentle injection.
