BACKGROUND The aim of this study is to investigate the pharyngeal airway space changes in patients treated with rapid palatal expansion (RPE) and Herbst appliance with or without skeletal anchorage. METHODS A 40-patient study group treated with the Herbst RME combination was included; moreover, a comparison between two subgroups based on whether miniscrews were used was evaluated. A subgroup ...

OBJECTIVE To evaluate the therapeutic effects of a preformed assembly of nickel-titanium (NiTi) and stainless steel (SS) archwires (preformed C-wire) combined with temporary skeletal anchorage devices (TSADs) as the sole source of anchorage and to compare these effects with those of a SS version of C-wire (conventional C-wire) for en-masse retraction. METHODS Thirty-one adult female patients ...

Objective: The purpose of this study was to evaluate the influence of the inter-radicular septum width in the insertion site of self-drilling mini-implants on the stability degree of these anchorage devices. Methods: The sample consisted of 40 mini-implants inserted in the inter-radicular septum between maxillary second premolars and first molars in 21 patients to provide skeletal anchorage for...

Downward and backward rotation of the mandible and/or excessive eruption of posterior teeth often cause anterior open bite. Depending on the severity of the case, orthognathic surgery is often the treatment of choice due to the difficulty of establishing absolute anchorage of molars by using a traditional orthodontic mechanics. This article reports the successful treatment of a severe skeletal ...

AIM Conventionally, noncompliance distal movement of molars relies exclusively on intraoral anchorage. The distal screw, a distal jet appliance supplemented by two paramedian mini-implants, is an innovative alternative. The aim of this study was to evaluate the suitability of this device to move molars bodily and distally. METHODS The effects of the distal screw were evaluated in a sample of ...

In severely protrusive patients, skeletal anchorage from miniscrew is often used to avoid anchorage loss with preferred miniscrew location near centre of resistance (Cres) of posterior teeth. Biomechanical requirement for directing retraction force towards Cres of posterior teeth demands the insertion of miniscrew in loose mucosa, where risk of infection and failure increases. In addition, unde...

Modinagar.U.P (M) 09910930544 [email protected] Abstract Class III malocclusion associated with skeletal anterior open bite pattern in adults can be a challenging orthodontic problem, especially if treated nonsurgically. Conventionally, several treatment alternatives are available such as tooth extraction, molar intrusion, and absolute anchorage system or orthognathic surgical corre...

mark of facial attractiveness.1,2 Skeletal asymmetries generally require surgical intervention to improve facial esthetics and correct any associated malocclusions. The classic approach in volves a presurgical phase of orthodontics, during which dental compensations are eliminated, and a postsurgical phase to refine the occlusion. The presurgical phase can be lengthy, involving tooth decompensa...

Active vertical control is critical in the treatment of hyperdivergent skeletal Class II malocclusion. The mechanics have been well shown as successful fixed appliance system with temporary anchorage devices (TADs); however, there are few relevant case reports clear aligner therapy (CAT). present report describes a severe using CAT extraction four premolars. was performed TADs, which facilitate...

Objectives: To find out success rate of mini-implants based on side insertion and type jaw. The aim orthodontic treatment is to maintain sufficient anchorage control create appropriate force systems that provide the desired effects. Implants have been used as skeletal devices for purposes. Material Methods: following study a systematic review mini-screws an intervention evaluate stability diffe...
