Dento-skeletal effects of the Pendulum Hygienic Distalizer.

Objectives: To evaluate dento-skeletal effects of the Pendulum Hygienic Distalizer (P.H.D), utilized on expansion of the maxillary arch and distalizing of maxillary first molars.

Evaluating the effect of Sabbagh Universal Spring during treatment of growing class II malocclusions.

Angle Class II division 1 malocclusion has been one of the most encountered problems in the orthodontic practice. In growing patients, mandibular repositioning appliances are the method of choice to induce mandibular growth and are termed functional appliances. This study was carried out to investigate the possible effect of the Sabbagh Universal Spring2 (SUS2) on the dental and skeletal cephalometric measurements in the permanent dentition of ten growing patients with Class II division 1 malocclusion and to compare its effect with the similar available data of similar fixed functional appliances.
