GERBER SPACE REGAINER PDF

The forces applied by the two appliances were 3N tipping and 15N bodily , respectively. Displacement and von Mises stress on the compact and cancellous bone, periodontal ligament PDL , crowns of the mandibular first, second permanent molars, and deciduous canines were calculated. Stress distribution and displacement values were measured via linear static analysis. However, such displacement was less at the other tested points when compared with that delivered by sagittal distalizer. The stresses created by Gerber appliance were higher in the crown and PDL of the deciduous canine than the crown of the first permanent molar crown. On the other hand, stress concentrations produced by Gerber space regainer are found to be more on the crown and PDL of the deciduous canine.

Space Regainer

A year-old female patient reported to the Department of Prosthodontics with a chief complaint of a gap between her right upper teeth which got exposed every time she smiled. This had resulted in distal migration of the adjacent canine into the premolar space, thereby creating two millimetres measured by a digital vernier calliper of space between the canine and the lateral incisor. The patient did not want any prosthetic treatment with regard to other edentulous areas due to missing first molars mandibular right and maxillary left , since they were not exposed whenever she smiled. The treatment plan was to move the right maxillary canine forwards by two millimetres to achieve contact with the lateral incisor using a fixed open coil space regainer OCSR , followed by placement of a fixed partial denture thereafter to replace the missing maxillary first premolar.
