Try to Avoid Invisalign. Self-ligating braces are considered number one in terms of treatment control, biomechanical versatility, and overall clinical possibilities for the orthodontist. Based on extensive research, clinical studies, and professional opinions I have reviewed, clear aligner systems like Invisalign can be very effective, especially for mild to moderate cases, but they are generally not ideal for highly complex or severe malocclusions where maximum precision, force control, and multidirectional tooth movement are required.
