Filter by:The goal of this prospective, single-arm clinical trial is to evaluate the speech performance of children with anterior dental crossbite before and after correction. Also, to assess the impact of early interceptive orthodontic treatment in the mixed dentition stage to correct the anterior dental crossbite on the quality of life of children. Fifty children of both sexes aged from 8 to 10 years were enrolled and evaluated using the study's inclusion & exclusion criteria. before beginning interceptive orthodontic treatment, each child underwent full mouth treatment. then, using a removable anterior expansion screw along with posterior bite planes to treat the anterior crossbite. All children were subjected to the Protocol of speech evaluation before appliance insertion and after complete correction of anterior crossbite. Also, the Child Perceptions Questionnaire (CPQ 8-10) in the Brazilian version was used to gauge how the anterior crossbite affected the children's oral health-related quality of life.
The posterior crossbite is a common type of malocclusion that might affect the normal growth pattern. Early treatment is recommended by rapid maxillary expansion with different appliances. This line of treatment needs a sufficient retention period to decrease the rate of relapse. The low level laser therapy has been used to enhance tissue regeneration. This study aims to compare the effect of rapid maxillary expansion with low level laser versus rapid maxillary expansion in children with posterior cross bite malocclusions.
Teenage children and adults often undergo orthodontic treatment each year to improve their dental esthetics and chewing function. One common problem they present with is having a small maxilla compared to the mandible. The standard of treatment to correct this issue is to expand the maxilla using either a tooth-anchored expander, a bone-anchored expander, or braces. Unfortunately, these treatment options can sometimes result in a loss of gum tissue and supporting structures of the teeth. Certain patients, especially ones that have thin gum tissue, are at a higher risk of this gum tissue loss. Orthodontic treatment for these patients will expand their jaw, causing further pressure on already thin gums. An increasingly common treatment to prevent this is to proactively modify patient's thin tissue surgically prior to their orthodontic treatment so they can withstand the tooth movement. The gold standard of doing this surgical intervention consists of harvesting a connective tissue from the palate which is not well tolerated by the younger population. Our study will evaluate the use of a biomaterial substitute instead of harvesting the patient's own tissue to thicken the gingival tissues. Surgical healing, patient satisfaction, pain index, as well as tissue contour post orthodontic treatment will be assessed thoroughly. This study will help us understand: 1) if biomaterials can be a substitute for traditional autogenous gum grafts to help thicken the patient's gum tissue prior to orthodontic treatment, and 2) if they are able to withstand the pressure of orthodontic movement. This will be the first long-term study of this kind.
in this study i will use to different designs of t maxillary hybrid expanders that consists of HYREX supported with tow miniscrews to treat the collapsed maxilla in Yonge adolescents
The aim of this study is to evaluate the levels of pain, discomfort and acceptance between two treatment modalities of Class III correction of growing patients in the late mixed dentition period.
Evaluating and comparing the short term effects of different palatal expanders on the amount of palatal expansion and buccal tipping of posterior teeth. Hypothesis: H0: There is no difference in the short term effects between the different palatal expanders. H1: There is a significant difference in the short term effects between the different palatal expanders.
Many author have exposed the rapid and slow expansion, the diversity of activation and containment protocols and the follow-up time, justify the need for more studies to evaluate the effects to the ERM for the long-term.
