Answer.

Optimal Orthodontic Force in Orthodontics

“Factors affecting force magnitude in orthodontics”

• Oppenheim and Schwarz had discovered optimum orthodontic force.
• Optimal orthodontic force is one which moves teeth most rapidly in the desired direction, with the least possible damage to tissue and with minimum patient discomfort.”
• It is also known as ideal orthodontic force.
• Optimal orthodontic force should be less than capillary blood pressure.
• Range of optimal orthodontic force is 20–26 gm/cm² of root surface.
• According to Schwarz value of optimum orthodontic force for tooth movement is 15 to 20 mm Hg of capillary pressure.
• Clinically, optimal orthodontic force produces rapid tooth movement with minimum patient discomfort and minimum lag phase and there is no marked mobility of teeth being moved.
• Histologically, vitality of tooth and supporting periodontal ligament is maintained and this produces direct frontal resorption.

Advantages of Optimum Orthodontic Force

• Tooth movement is efficient.
• Resorption is of frontal type.
• There is elimination of lag phase and hyalinized zone.
• There is less pain and no damage to supporting structures.
• Chances for the root resorption are very less.
