Article Synopsis
- * A case study details the orthodontic treatment of a 21-year-old woman with maxillomandibular protrusion and impacted mandibular second molars, using the innovative Physiologic Anchorage Spee-wire System (PASS) for effective alignment and resolution of impaction.
- * The PASS technique proved to be a simple and efficient method for correcting dental issues, showing superiority over traditional wire appliances and minimizing discomfort during treatment while achieving a well-aligned dentition.

Objective: To investigate changes in the circum-maxillary sutures during alternate maxillary expansions and constrictions in a rat model.
Methods: Twenty-two male Sprague-Dawley rats (6 weeks old) were used and divided into three groups. In maxillary expansion (ME) group (n=9), an expander was activated for 5 d, and then sacrificed.

The purpose of this study was to evaluate whether the cranial and circumaxillary sutures react differently to maxillary expansion (ME) and alternate maxillary expansions and constrictions (Alt-MEC) in a rat model. Twenty-two male Sprague-Dawley rats (6 weeks old) were used and divided into three groups. In ME group (n=9), an expander was activated for 5 days.

Objective: To compare the angular changes in the developing mandibular third molars in the mandibular second premolar extraction and non-extraction cases and to determine whether the mandibular second premolar extraction causes favorable rotational changes in the angulations of the developing mandibular third molars and benefits its later eruption.
Methods: Pretreatment and posttreatment panoramic radiographs were taken from 45 subjects who had been treated by the extraction of the mandibular second premolars and 48 subjects who had been treated without extraction. The horizontal reference plane was used to measure and compare the changes in the angulations of the developing mandibular third molars.
