“…The results of the current study showed that average miniscrews' head displacement was more than average miniscrews' tail displacement (0.6mm and 0.2mm respectively). This comes in agreement with El-Beialy et al 6 and Pongsamart P et al 25 Moreover, In the current study, miniscrew head was always displaced in the same direction of force, however, the tail displacement was either in the direction of the force (this was seen in 14 miniscrews) or in the opposite direction (which was seen in 8 miniscrew). This comes in accordance with the results of Drescher D et al 9 in their systmatic review where miniscrews' head displacement ranged from 1.0 to 4.1 mm compared to 1.0 to 1.92 mm displacement of the miniscrews' tail.…”

“…The optimal force for canine retraction was reported to be 150 to 200g 31 . Pongsamart et al concluded that the lighter the force applied to a miniscrew, the more stable the miniscrew will be 25 . Therefore, the minimum optimal force for canine retraction was used in the current study (150g).…”

“…El-Beialy et al 6 found displacement of 40 miniscrews inserted between 2nd premolar and 1st molar used in upper and lower canines' retraction for 6 months with 150 and 250g force of retraction. Pongsamart P et al 25 concluded that even 50gm of forces applied for 3 months resulted in miniscrew displacement.…”

“…The data from the CBCT scans (T1 and T2) was exported in Digital Imaging and Communications in Medicine (DICOM) format and processed using the 3D module in OnDemand3D™ software. A xed anatomical bony reference point (anterior nasal spine) was chosen, and the linear distance between the head and the tail of each miniscrew was recorded in relation to anterior nasal spine before and after retraction 25 .…”

Background: Evaluating the effect of low level laser therapy (LLLT) on miniscrew displacement and gingival inflammation around miniscrew. Methods: Twenty-four buccal intra-alveolar miniscrews were inserted on right and left sides for maxillary canine retraction after 1st premolar extraction. The sides were randomly allocated into experimental side; which received low level laser (LLL) application after miniscrew insertion and a control side which received no Laser application. Miniscrews on both sides were loaded with 150gm of force, 14 days after their insertion. Gingival inflammation around miniscrew was assessed using gingival index throughout the study period and miniscrew displacement was evaluated using CBCT after six months of active canine retraction.Results: All miniscrews showed displacement with no significant difference between control and experimental sides. LLLT successfully reduced gingival inflammation at miniscrew site, as evidenced by gingival index.Conclusions: LLLT can be proposed as clinical procedures to add in success of miniscrews , however LLLT does not decrease miniscrew displacement .Trial registration: NCT05092633 ClinicalTrials.gov.

“…To effectively use implant anchors, many researchers have made preoperative assessments of micro-screw implant sites by using cone beam computed tomography (CBCT). Their results have shown that based on CBCT, cortical bone thickness and sclerotin conditions could be effectively assessed, and the percentage of successfully implanted micro-screws could be effectively increased (Prasanpong et al, 2014;Qiu et al, 2016).…”

Background: To determine the optimal implantation site of orthodontic micro-screws based on cone beam computed tomography (CBCT) analysis in the mandibular anterior tooth region, provide a theoretical basis for orthodontic implant placement and improve post-implantation stability.Methods: Forty patients who underwent CBCT scanning were selected for this study. CBCT scanning was applied to measure the interradicular distance, buccolingual dimension, labial cortical bone thickness and lingual cortical bone thickness between mandibular anterior teeth at planes 2, 4, 6, and 8 mm below the alveolar ridge crest. The data were measured and collected to obtain a comprehensive evaluation of the specific site conditions of the alveolar bone.Results: The interradicular distance, buccolingual dimension and labial cortical bone thickness between the mandibular anterior teeth were positively correlated with the distance below the alveolar ridge crest (below 8 mm). The interradicular distance, buccolingual dimension, labial cortical bone thickness, and lingual cortical bone thickness were all greater than those in other areas between the lateral incisor root and canine incisor root 4, 6, and 8 mm below the alveolar ridge crest.Conclusion: The area between the lateral incisor root and the canine incisor root in planes 4, 6, and 8 mm from the alveolar ridge crest can be used as safe sites for implantation, while 8 mm below the alveolar ridge crest can be the optimal implantation site. An optimal implantation site can be 8 mm below the alveolar ridge crest between the lateral incisor root and the canine incisor root.
