“…Previous studies have investigated orthodontic treatment with and without piezocision, 6,7,14,15,34 but none has quantified tooth movement three-dimensionally, considering detailed IOS crowns and root canal segmentations from CBCTs simultaneously to determine changes in tooth long axis and 3D linear displacements.…”

“…In this study, we innovatively evaluated the influence of piezocision surgery on orthodontic biomechanics, magnitude and direction of tooth movement using AI-based automated tools. Previous studies have investigated orthodontic treatment with and without piezocision, 6 , 7 , 14 , 15 , 34 but none has quantified tooth movement three-dimensionally, considering detailed IOS crowns and root canal segmentations from CBCTs simultaneously to determine changes in tooth long axis and 3D linear displacements. The influence of the piezocision in the teeth responses to orthodontic forces, changes in the amount and direction of orthodontic three-dimensional tooth displacement remains unclear.…”

“…Due to the lack of studies and significant differences in methods, sample size, arches and groups of teeth studied, it was challenging to establish a comparison with previous reports. In this study, we evaluated the tooth movement of all lower teeth after correcting mild to moderate malocclusion, while the literature mainly reports different evaluations and methodologies, such as the levelling of only mandibular anterior teeth, 27 assessment of severe maxillary malocclusion, 6 evaluation of maxillary canine distalization, 14 en-masse retraction utilizing miniscrews, 35 transversal tooth movement of mandibular lateral segments, 15 second molar protraction and upper canine retraction. 36 …”

“…[8][9][10][11] Even though studies have reported that piezocision shortens orthodontics treatment time, 6,12,13 the literature still shows controversial results. 14,15 In addition, the influence of this procedure in the teeth responses to orthodontic forces (biomechanics), as well as changes in the amount and direction of orthodontic three-dimensional tooth displacement remains unknown.…”

Objective(s)This study aims to evaluate the influence of the piezocision surgery in the orthodontic biomechanics, as well as in the magnitude and direction of tooth movement in the mandibular arch using novel artificial intelligence (AI)‐automated tools.Materials and MethodsNineteen patients, who had piezocision performed in the lower arch at the beginning of treatment with the goal of accelerating tooth movement, were compared to 19 patients who did not receive piezocision. Cone beam computed tomography (CBCT) and intraoral scans (IOS) were acquired before and after orthodontic treatment. AI‐automated dental tools were used to segment and locate landmarks in dental crowns from IOS and root canals from CBCT scans to quantify 3D tooth movement. Differences in mesial‐distal, buccolingual, intrusion and extrusion linear movements, as well as tooth long axis angulation and rotation were compared.ResultsThe treatment time for the control and experimental groups were 13.2 ± 5.06 and 13 ± 5.52 months respectively (P = .176). Overall, anterior and posterior tooth movement presented similar 3D linear and angular changes in the groups. The piezocision group demonstrated greater (P = .01) mesial long axis angulation of lower right first premolar (4.4 ± 6°) compared with control group (0.02 ± 4.9°), while the mesial rotation was significantly smaller (P = .008) in the experimental group (0.5 ± 7.8°) than in the control (8.5 ± 9.8°) considering the same tooth.ConclusionThe open source‐automated dental tools facilitated the clinicians' assessment of piezocision treatment outcomes. The piezocision surgery prior to the orthodontic treatment did not decrease the treatment time and did not influence in the orthodontic biomechanics, leading to similar tooth movements compared to conventional treatment.

“…The present study had similar findings to a study conducted by Tuncer 14 wherein no significant results were noted between the piezocision-assisted and conventional canine retraction approaches. A recent split-mouth study conducted by Hawkins et al 15 in 2022 demonstrated no statistically significant results when comparing the orthodontic tooth movement on the piezocision and control side, furthermore patients experienced the pain related to the procedure.…”

Aim: To assess and compare the efficiency of tooth movement in patients subjected to piezocision and photobiomodulation as part of a split-mouth clinical experiment, and to combine their effects in order to derive a synergetic effect if any. Methods: 24 subjects requiring bilateral first premolar extractions were selected for the study. The study had a split mouth design with patients subjected to either piezocision, photobiomodulation or a combination of the two techniques in one quadrant and the opposite quadrant served as the control. Piezocision was carried out by placing vertical interproximal incisions on the mesiobuccal and distobuccal aspect of the maxillary canine, whereas photobiomodulation was carried out at ten sites, five on the buccal aspect and five on the palatal aspect with a total energy of 10J in the period between the three weeks. Results: There was no statistically significant difference observed in terms of accelerated tooth movement between piezocision, photobiomodulation or combination of the two techniques and the conventional technique. Conclusion: Although no statistically significant findings were derived, a synergistic effect was observed with the combined effect of piezocision and photobiomodulation showing an enhanced effect. Increased rate of tooth movements were observed in both piezocision and photobiomodulation group with lowest effect seen in the photobiomodulation group.
