A randomized clinical trial to assess the sagittal effects of Transforce transverse appliance (TTA) and NiTi palatal expander (NPE) on skeletal class II malocclusion in growing patients during retention phase - A cephalometric study using a historical control group.

Objectives: To evaluate and compare the skeletal changes during the retention period after expansion with "Transforce Transverse lingual or palatal Appliance®" (TTA) and "NiTi Palatal Expander®" (NPE) in growing subjects with class II division 1 malocclusion and to compare these changes with a matched historical control.

Subjects And Methods: A unicentric two arm, parallel randomized clinical trial with additional historical control group was conducted over a period of six years. The subjects in the age group of 9-13 years were screened and recruited as they reported.

Effectiveness of reverse twin block with lip pads-RME and face mask with RME in the early treatment of class III malocclusion.

Background: The use of face mask for early treatment of class III malocclusion has proven to be successful, but its compliance and related dental side effects have always been a problem. To overcome this, a new approach has been suggested. The purpose of the present study was to compare the effectiveness of reverse twin block with lip pads and fixed rapid maxillary expansion (RTBLP-RME) appliance and face mask with RME (FM-RME) appliance for early treatment of class III malocclusion.

Early correction of unilateral scissor bite using transforce appliance and modified twin block appliance.

Early treatment of scissor bite has been advocated mainly to prevent function jaw shift that can eventually lead to permanent skeletal asymmetry and temporomandibular joint pathosis. Although unilateral scissor bite is more common, most of the times, bilateral mandibular expansion is indicated. Lingual transforce appliance can be useful in such cases.

Comparison of temporomandibular joint changes in Twin Block and Bionator appliance therapy: a magnetic resonance imaging study.

Background: The objective of the present study was to evaluate and compare temporomandibular joint changes especially disk-condyle-fossa relationship following functional treatment of skeletal class II division 1 malocclusion using Twin Block and Bionator appliances.

Methods: The total sample consisted of 30 subjects (13 males and 17 females) with class II division 1 malocclusion having mandibular retrognathism, in the age group of 9 to 14 years. Two treatment groups, i.

The relationship between salivary insulin-like growth factor I and quantitative cervical maturational stages of skeletal maturity.

Objective: Insulin-like growth factor (IGF-I) has been used as an indicator of growth hormone levels and hence can also be used as a marker of growth. The main objective of the study was to quantify salivary IGF-I levels and its secretion rate at different quantitative cervical maturation (QCVM) stages and evaluate a possible role for salivary IGF-I in evaluating skeletal growth.

Methods: Forty-five subjects (24 female, 21 male) between the ages of 7 and 23 years were included in the study.

Comparison of sagittal anchorage conservation of mini-implants and modified Nance palatal buttons.

Objective: To compare the anchorage potential of mini-implants with modified Nance palatal buttons during simultaneous first and second maxillary molar distalization.

Methods: Mini-implants (1.4 x 10 mm) placed to obtain indirect anchorage for maxillary molar distalization using a superelastic Ni-Ti open coil spring were compared with anchorage derived from a modified Nance palatal button incorporated in a distal jet appliance.

Speech defect and orthodontics: a contemporary review.

In conjunction with the lips, tongue, and oropharynx, the teeth play an important role in the articulation of consonants via airflow obstruction and modification. Therefore, along with these articulators, any orthodontic therapy that changes their position may play a role in speech disorders. This paper examines the relevant studies and discusses the difficulties of scientific investigation in this area.

Spring-loaded bite-blocks for early correction of skeletal open bite associated with thumb sucking.

Skeletal open-bite malocclusion is frequently discussed in orthodontics. Diagnosis, treatment, and retention can be difficult because this malocclusion has numerous correlated etiologic factors. The earlier this malocclusion is corrected, the better the prognosis will be, especially when the problem is skeletal.

Distalization of molars using two stage mini-implants -- a case report.

This article describes a two stage mini-implant approach to distalize the maxillary molars and then retract the anterior teeth into class I, providing a non-compliant, non-extraction treatment.

A new approach of assessing sagittal dysplasia: the W angle.

In orthodontic diagnosis and treatment planning, an accurate antero-posterior measurement of jaw relationships is critically important. Previously described angular and linear measurements can be inaccurate because of their dependency on various factors. The purpose of this study was to introduce a new cephalometric measurement, named the W angle, to assess the sagittal relationship between maxilla and mandible with accuracy and reproducibility.

Static frictional force and surface roughness of various bracket and wire combinations.

Introduction: During sliding mechanics, frictional resistance is an important counterforce to orthodontic tooth movement, which must be controlled to allow application of light, continuous forces. We investigated the static frictional resistance between 3 modern orthodontic brackets-ceramic with gold-palladium slot, ceramic, and stainless steel-and 4 archwires (0.019 × 0.

Early management of skeletal open bite with spring-loaded and magnetic bite blocks.

The purpose of this study was to evaluate the effects of spring-loaded and magnetic bite blocks in growing individuals with skeletal open bites. The sample consisted of patients between 8 and 13 years of age randomly divided into two groups. One group was treated with spring-loaded bite blocks while the other received treatment with magnetic bite blocks.
