ABSTRACT
OBJECTIVES: The objectives of the study was to assess and compare the cranial base morphology in long face and short face. METHODOLOGY: The study comprises 64 individuals (32 in each group). Group I consists of individual's with long face and group II comprises individuals with short face. Individuals were classified into groups with the help of lateral cephalometric parameters like Gonial Angle, Anterior facial height, Posterior facial height, Jarabak's Ratio, and Y-axis. Linear and angular measurement in the cranial base was taken. RESULT: The results showed statistically significant difference in Sella-Nasion, Sella-Basion and Nasion-Sella-Basion between the two groups. Sella-Spinoethmoidal suture, Nasion-Spinoethmoidal suture, Spinoethmoidal suture-Sella-Basion, Frankfurt Horizontal-Sella-Nasion, Frankfurt horizontal-Sella-Basion, Frankfurt horizontal-Sella-Spinoethmoidal suture showed no statistically significant difference among the groups. CONCLUSION: The study concluded that individuals with long face have a greater Sella-Nasion, Sella-Basion, Nasion-Sella-Basion compared to individuals with short face.
ABSTRACT
Anterior open bite is defined as a condition in which upper incisor crowns fail to overlap the incisal third of the lower incisor crowns when the mandible is brought into full occlusion. The diagnosis, treatment, and successful retention of treated open-bite malocclusion continue to be a constant subject of discussion and study, contributing to the frustrations of clinicians. Various modalities have been used for the correction of open bite for the different age groups. In adult cases, an open bite can be corrected either by anterior extrusion or posterior intrusion, or a combination of both. Kim had described a method of using multiloop edgewise archwire for posterior intrusion. Here is a case report in which an innovative method is described which is a modification of Kim's method which is simpler, less time-consuming to place, hygienic, and they do not irritate the soft tissue. The bite closing mechanism and the treatment results are similar to Kim's method.
