In recent times, the use of miniscrew implants to obtain absolute anchorage has gained momentum in clinical orthodontics as rigid anchorage modality. Miniscrew implants offers many advantages when used as temporary anchorage devices like, easy placement and removal, immediate loading, can be used in a variety of locations, provide absolute anchorage, economic and requires less patient cooperati...
A 17 years old male patient presented with impacted mandibular right canine and partially erupted left canine, overjet of 0.5mm 100% overbite. He was treated fixed orthodontic treatment disimpaction using skeletal anchorage in maxillary arch to avoid undesirable effects on dentition. Pre-treatment post records were taken evaluate the changes.
Background: Severe forms of scissor bite or Brodie syndrome is rare orthodontic malocclusion that occurs with a frequency of 0.01% in general population. Several methods have been described to obtain a correction from a dental, skeletal and soft tissutal points of view. In literature it was described: jaws osteotomies, surgery first approach, as the use of orthopedic-functional devices and extr...
351 P of mandibular molars is challenging because of the high density of mandibular bone. Anterior dental anchorage is often inadequate to protract even a single first molar without reciprocal retraction of the incisors or movement of the dental midline. Furthermore, if the buccal and lingual cortical plates in the edentulous region have collapsed, safe and effective protraction may be impossib...
Anchorage conservation has always been a challenge in orthodontics especially in cases requiring group movement of teeth. The drawbacks of conventional anchorage conservation methods like headgears and intermaxillary elastics have been overcome with the advent of skeletal anchorage. Mini-implants which have been proved successful in several intraoral locations for anchorage, can also be success...
AIM To assess if mandibular incisor proclination and protrusion during treatment with the Herbst/multibracket appliance can be prevented through simple screws (MIs) anchorage. MATERIAL AND METHODS After a statistical power analysis, 12 Herbst patients with MIs (100% MIs survival) ligated to the Herbst/multibracket appliance to reinforce anchorage were investigated. A control group matched for...
The aim of this case report is to describe the treatment of a patient with skeletal Class III malocclusion with maxillary retrognathia using skeletal anchorage devices and intermaxillary elastics. Miniplates were inserted between the mandibular lateral incisor and canine teeth on both sides in a male patient aged 14 years 5 months. Self-drilling mini-implants (1.6 mm diameter, 10 mm length) wer...
The aims of the present study were to assess the effectiveness of skeletal anchorage for intrusion of maxillary posterior teeth, to correct open bite malocclusion, and to evaluate the usage of titanium miniplates for orthodontic anchorage. Anterior open bite is one of the most difficult malocclusions to treat orthodontically. Currently, surgical impaction of the maxillary posterior segment is c...
ment can be particularly challenging in adult patients. Although many appliances have been proposed for maxillary molar distalization in such cases,1,2 they generally require some degree of patient compliance, and their de sign causes anchorage loss due to the incorporation of occlusal rests or bands on the premolars. The introduction of skeletal anchorage has radically changed orthodontists’ a...
