: the purpose of this study was to evaluate the dento-skeletal effects of the mini-implant supported Twin Block versus the incisal capped appliance in the treatment of skeletal class II patients with mandibular retrognathism. Methods: Twenty patients with skeletal class II mandibular retrusion were included in the study. They were recruited with a random and equal allocation into 2 groups. The first group was treated with incisal capped TB without skeletal anchorage. The second group were treated with mini-implant supported TB. The mini-implants were inserted in the inter-radicular region between the mandibular second premolar and first molar. Intra-oral elastics were attached from the mini-implant to the wire hook in the canine region of the lower part of the TB and they were changed every 24 hrs. 100 to 150 gm of force was applied. Cephalometric radiographs were acquired at the beginning (T1) and end of treatment (T2). The paired-samples and independent-samples t-tests were used to evaluate and compare the changes within groups and between groups, respectively.
this is a controlled clinical trial with 2 groups of patients of class II skeletal discrepancy due to mandibular retrusion one group is treated with twin block functional appliance and the other with twin block combined with low level laser therapy ,the study aims to detect the effect of low level laser on the skeletal outcomes , dentoalveolar outcomes, rate of correction and pain during treatment
60 patients will be treated by extraction of maxillary first premolars by applying mini-screws between the maxillary second premolar and first molar as temporary skeletal anchorage devices (TSADs). They will be divided randomly into three groups in this trial. The prolonged duration of the treatment period can cause many side effects such as white spots, caries, periodontal diseases, and pain and discomfort. So many efforts have been made to reduce the treatment time. Many procedures have been introduced to accelerate orthodontic tooth movement, which can category as surgical or non-surgical. Piezocision is a minimally invasive surgical method for accelerating orthodontic tooth movement and shortening treatment time. Low-level laser therapy (LLLT) is one of the physical acceleration methods that have contributed to decreasing treatment time.
Thirty-eight patients requiring extraction of maxillary first premolars will participate in the study. They will be divided randomly into two groups: an en-masse retraction group and a two-step group. In each group, anterior teeth retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side, Mini-implants will be used as an anchor unit in the en-masse retraction group, and TPA in the two-step's retraction group. The levels of pain, discomfort, and functional impairments will be self-reported using a validated questionnaire with a 4-points Likert scale.
There is a scarcity in literature regarding the influence of maxillary third molar on distalization . This study aimed to compare the influence of unerupted maxillary third molars and their extraction on the bilateral distalization of upper first molars using the infra-zygomatic gear distalizer
There is a scarcity in the current literature regarding such appliance and its effect on distalizing the first maxillary molar in absence of the second molar. Therefore, this study was made to evaluate the effect of bilateral distalization of upper first molars in a group of patients after extraction of maxillary second Molars using infra zygomatic mini implants.
Fixed Functional Appliances comparisons in treatment of orthodontic class II malocclusion cases
This study will be directed to evaluate The effect of two different types of fixed functional appliances on the temporomandibular joint. Study design: Prospective randomized clinical study. Study setting and population: This study will be conducted on twenty orthodontic patients. The number of patients was dependent on a power study. Sample size calculation was based on the observed average effect size derived from previous article addressing "the effect of skeletally anchored Forsus FRD using miniplates for the treatment of Class II malocclusion
the objective of the current study is to compare the dentofacial effects of the mini-plate anchored Herbst appliance Versus the dentally anchored Twin force bite corrector Appliance in Young Adult Class II Orthodontic Patients with retruded mandible.
