简要总结
The study aims to compare the anchorage control using arch wire stopper versus mini-screws in post-pubertal patients with maxillary dentoalveolar protrusion
详细描述
The study begins with patient selection according to inclusion and exclusion criteria, followed by treatment planning, and then bonding of orthodontic brackets of the upper and lower arches, including the second maxillary molars.
After leveling and alignment for all participants, the extraction of the maxillary first premolars will be performed.
• In the "Intervention Group" Canine retraction will be performed on 0.017×0.025 ss archwire with an archwire stopper mesial to the upper first molar.
Afterwards, anterior segment retraction will be done using T-loop on 0.017x0.025 TMA archwire
• In the "Comparator Group" Canine retraction on 0.017×0.025 ss archwire with the upper first molars indirectly anchored to inter-radicular mini screws Afterwards, anterior segment retraction will be done using T-loop on 0.017x0.025 TMA archwire

入选标准
- •Post-pubertal female patients.
- •Cases with bimaxillary protrusion or Class II Division 1 malocclusion that require maxillary first premolars extraction.
- •Full permanent dentition (not necessitating third molars).
- •Good oral hygiene.
排除标准
- •Medically compromised patients.
- •Active periodontal disease or obvious bone loss in the maxillary arch.
- •Patients with habits that are detrimental to dental occlusion (thumb sucking, tongue thrusting).
- •Smoking or any systemic diseases.
- •Chronic use of any medications including antibiotics, phenytoin, cyclosporine, anti-inflammatory drugs, systemic corticosteroids, and calcium channel blockers. All the above factors affect the rate of tooth movement
- •Previous orthodontic treatment.
- •Missing teeth.
研究组 & 干预措施
arch wire stopper mesial to the maxillary first molar group
In postpubertal female patients with maxillary dentoalveolar protrusion, canine retraction after the extraction of the maxillary first premolars with archwire stoppers mesial to the maxillary first molars followed by anterior segment retraction using T-loop on 0.017x0.025 TMA arch wire.
干预措施: archwire stopper mesial to the maxillary first molar group (Device)
maxillary first molar indirectly anchored to the inter-radicular mini-screw group
In postpubertal female patients with maxillary dentoalveolar protrusion, canine retraction after the extraction of the maxillary first premolars, with the maxillary first molars indirectly anchored to the inter-radicular mini-screw followed by anterior segment retraction using T-loop on 0.017x0.025 TMA arch wire.
干预措施: inter-radicular mini-screw (Device)
结局指标
主要结局
Amount of anchorage loss of the maxillary first molars
时间窗: 6 months from the start of the canine retraction and after anterior segment retraction (12 months)
After full canine retraction, the amount of anchorage loss (mesial movement) of the maxillary first molars of will be assessed on the digital models
次要结局
- Tipping of the maxillary first molar.(6 months from the start of the canine retraction and after anterior segment retraction (12 months))
- Maxillary incisors inclination(6 months from the start of the canine retraction and after anterior segment retraction (12 months))
- Maxillary incisors anteroposterior position(6 months from the start of the canine retraction and after anterior segment retraction (12 months))
