Objective:
For a long time orthodontic treatment was doing according to the basic and unchangeable rules that leaded to extraction or orthognathic surgery in most patients. In recent decade new technologies and techniques have came to orthodontic science and have made treatment easier and more alternatives for treatment.
Methods and Materials:
There are four cases with severe dental and skeletal problems that treated without surgery and without extraction by using a passive self-ligating system and in one of them in combination with miniscrews in upper arch.
1- A 24 years old girl with maxillary constriction, mandibular deviation, maxillay crowding about 13 mm, mandibular crowding about 5 mm, mandibular dental deviation (2mm), posterior bilateral crossbite and lateral openbite. She was treated without surgery, extraction, using of any expander appliance and any auxiliary appliance in 20 months and 13 visits.
2- A 18 years old boy with severe anterior openbite , crowding  in upper and lower arches, maxillary constriction ,  posterior crossbite and high angle mandibular plane. He did not accept surgical procedure. He was treated in 20 months and 12 visits non surgical, nonextracted, without using of expander appliance.
3-A 16 years old girl with skeletal cl III, Maxillary crowding was about 10mm. The patient did not accept surgery so camouflage treatment was done. She was treated in 15 months and 10 visits nonsurgical and non extracted without using any auxiliary appliances.
4-A 14 years old girl with lower midline deviation, severe malpositioned upper left cuspid and posterior cross bite. She was treated in 15 months and 8 visits.
Results:
 All of the cases have a fine occlusion at a final of treatment.
Conclusion:
Nowadays we can treat complex problems by new techniques and technologies easier in a fewer time and fewer visits.
