Introduction to Extraction Space

What is/are Extraction Space?

Extraction Space - Inter canine width and extraction spaces at three time intervals during the observation period. ^[1] Periodontally accelerated osteogenic orthodontics, a newly evolved technique, involves a combination of corticotomy followed by placement of bone graft and orthodontic force application for the closure of extraction space. ^[2] To systematically evaluate scientific data on the effectiveness and side effects of surgical and non-surgical methods in accelerating orthodontic treatment in situations with the removal of premolars and subsequent closure of the post-extraction spaces. ^[3] The mandibular left third molar was moved to the second molar extraction space by using orthodontic mini-implant anchorage. ^[4] Closed NiTi coil springs were used to retract canines into the extraction spaces. ^[5] CONCLUSIONS Daily 5-minute application of LED did not result in clinically meaningful differences during extraction space closure compared with no LED application. ^[6] Objectives: On a long-standing extraction space, resorption results in a decrease in the vertical height of the bone, but more importantly, remodelling produces a buccolingual narrowing of the alveolar process as well. ^[7] Maintaining torque with sliding mechanics in maxillary anterior teeth especially in presence of large extraction spaces has become a major concern among orthodontist. ^[8] Results and Conclusion: All the set objectives were accomplished at the end of the study which included complete closure of extraction space by retraction and intrusion in the models. ^[9] The stress distribution of PDL on both sides of the extraction space was broad which consistent with the trend of tooth movement. ^[10] Multiple logistic regression analysis was used to estimate the influence of the aforementioned independent variables on the frequency of extraction space reopening. ^[11] Measurement was done till closure of the extraction space (when both canines touch the mesial surface of the upper second premolars) Conclusion 1. ^[12] The treatment × time interaction showed no statistically or clinically significant differences in maxillary extraction space closure (b = -0. ^[13] Background Extraction of the first premolar followed by canine retraction into the extraction space is a common treatment in orthodontics. ^[14] MATERIALS AND METHODS The canines in 64 quadrants were randomly retracted into the first premolar extraction spaces using NiTi closed coil springs or elastomeric chains, in the maxilla and mandible. ^[15] The relationship between ipsilesional CST FA and UE FM was significant for all approaches and similar regardless of extraction space. ^[16] The purpose of this study was to increase the scale of the extraction space through hydrodistillation made from microwaves to produce citronella oil with high yield. ^[17] 3rd molars spontaneously erupted in the extraction space of 2nd molar. ^[18] Using double loop springs incorporated into an archwire made of gum metal (GUM) and titanium molybdenum alloy (TMA), the maxillary anterior teeth were moved distally to close an extraction space. ^[19] Frictionless mechanics for extraction space closure is one of the commonly used method in orthodontic practice. ^[20] After mini-screw implants were inserted into the buccal region between the second premolar and first molar, 150 g of force was applied to retract the upper and lower anterior teeth to close the extraction space on each side. ^[21] METHODS Twenty-one patients who needed bilateral maxillary canine retraction to close extraction space as part of their treatment plan were selected for this study. ^[22] Due to the extraction of thick coal seam, there will be three main zones formed above the extraction space: caved zone, fractured zone and continuous deformation zone, as the fractured zone is full of vertical and horizontal fractures, and these fractures consist of the gas channel for gas flow, and it can be used for gas drainage to eliminate gas disaster, so the objective of this paper is to find the effect of different gob behavior to the height and scope of the fractured zone. ^[23] Extraction spaces (7. ^[24] The extraction space quickly disappeared during extraction site preparation. ^[25] Objectives: This study aims to compare the measurements of the extraction spaces in the plaster models and digital dental models and to investigate the usability of the digital models in preventive and interceptive appliances in pediatric dentistry clinics. ^[26] Preorthodontic socket preservation after tooth extraction is intended to enhance favorable dentoalveolar ridge morphology and architecture, and facilitate orthodontic tooth movement (OTM) and extraction space closure. ^[27] BackgroundSliding mechanics with miniscrews is recently used for extraction space closure. ^[28] All the examined teeth had tipped and moved towards the extraction space, leading to space decreases. ^[29] We conclude that when the structure and characteristics of the classifier are limited, a reasonable selection of the feature extraction space can help improve the characteristics of the classifier and better achieve the downstream tasks in the security field. ^[30] At the same time, we should be careful of root resorption of the teeth on both sides of the extraction space. ^[31] The camouflage treatment plan included bilateral extraction of the maxillary first premolars combined with the use of temporary anchorage devices (TADs) and tension coil springs to retract canines into the extraction spaces and then the 4 incisors. ^[32] MATERIALS AND METHODS: ASIST measurements of maxillary canines that were actively retracted into an extraction space were collected approximately once per month for 12 adolescent female patients. ^[33] The lower third molars were uprighted and the extraction spaces closed. ^[34] OBJECTIVES To compare the time to close extraction spaces between en masse (ER) and two-step retraction (TSR). ^[35] Post-extraction spaces were measured and compared with post-retraction spaces of upper cuspids. ^[36] A miniscrew-assisted straight wire technique was used to close the extraction space and reduce the overjet. ^[37] Objective Sliding mechanics using orthodontic miniscrews is widely used to stabilize the anchorage during extraction space closure. ^[38] A computed tomography (CT) scan was performed after alignment of teeth, and a second CT scan was performed at the end of extraction space closure in both groups. ^[39]
