“…Similar results have been suggested by Li et al [ 69 ] with intermittent parathyroid hormone administration, by Duliamy et al [ 70 ] with local injection with strodium, by Al-Fakhry et al [ 71 ] with injectable platelet rich fibrin (i-PRF) administration and by Zhao et al [ 40 ] with local OPG (osteoprotegerin) gene transfer to periodontal tissues. Ozturk et al [ 72 ] investigated the effect of photobiomodulation and high frequency mechanical vibration three-dimensionally and molecularly and found that both can support post-treatment retention. The supportive effects of vibration for orthodontic retention were also highlighted in the study of Yadav et al [ 73 ].…”

Direct 3D-Printed Orthodontic Retainers. A Systematic Review

Three-dimensional (3D) printing technology has shed light on many fields in medicine and dentistry, including orthodontics. Direct 3D-printed prosthetics, implants or surgical devices are well-documented. The fabrication of orthodontic retainers using CAD technology and additive manufacturing is an emerging trend but the available data are scarce. The research approach of the present review included keywords in Medline, Scopus, Cochrane Library and Google Scholar up to December 2022. The searching process concluded with five studies eligible for our project. Three of them investigated directly 3D-printed clear retainers in vitro. The other two studies investigated directly 3D-printed fixed retainers. Among them, one study was in vitro and the second was a prospective clinical trial. Directly 3D-printed retainers can be evolved over time as a good alternative to all the conventional materials for retention. Devices that are 3D-printed are more time and cost efficient, offer more comfortable procedures for both practitioners and patients and the materials used in additive manufacturing can solve aesthetic problems, periodontal issues or problems with the interference of these materials with magnetic resonance imaging (MRI). More well-designed prospective clinical trials are necessary for more evaluable results.

“…The orthodontic appliances were removed, and a retainer was fitted using a prestretched ligature wire (Ortho Technology) extended from the first molar to the incisors, keeping the level of force as low as possible to avoid continuous mesial movement or avulsion of the tooth. The retainer was left for 7 days (Li et al, 2016 ; Öztürk & Gül Amuk, 2021 ) (Figure 2c ).…”

ObjectivesThis study aims to evaluate the effect of vitamin D deficiency (VDD) on orthodontic tooth movement (OTM), retention, and relapse and to assess the effect of systemic administration of vitamin D (VD) in a rat model.Materials and MethodsA total of 32 male Wistar rats were divided into two groups, a control group of 11 rats and an experimental group of 21 rats with VDD, after enhancement using a custom diet. Of the VDD group, 11 rats were supplemented with systemic vitamin D3 and categorized as vitamin (VD supplement [VDS]) groups. The VDS group received 40,000 IU/kg via intramuscular injection on Days 1 and 15 of the orthodontic treatment period. A modified orthodontic appliance was fitted to apply 0.5 N of force to move the maxillary right first molars mesially for 14 days, followed by retention and relapse periods for 7 days. Space created during OTM was measured and reassessed after the retention and relapse periods. The relapse ratio was estimated, and histomorphometric analysis was performed to assess the number of osteoblasts, osteoclast bone cells, and bone area.ResultsA significant increase in the relapse ratio and a reduction in osteoblast cells and bone area were observed in the VDD group. By contrast, the amount of tooth movement was significantly higher together with osteoblast cells and bone marrow in VDS with a significant reduction in relapse ratio.ConclusionVDD was associated with a significant reduction in osteoblast cell count and total bone area in addition to a significant increase in relapse ratio. Routine screening of VD may be beneficial before commencing orthodontic treatment.

“…Eight articles were included in which the effect of vibrations on alveolar bone was evaluated; one study used a white rabbit [23], and six studies were performed in Sprague Dawley rats [3,6,9,13,24,25] and one study in mice [26].…”

confidence: 99%

“…All the included studies used mechanical vibrations; four applied LFVs (≤45 Hz) [6,9,23,26], and four involved HFVs (≥90 Hz) [3,13,24,25] in their protocols; nevertheless, one article combined high and low frequency [24]. Regardless of the study, all of them had as their main objective to evaluate the effect of mechanical vibrations on alveolar bone formation, measuring for this purpose craniofacial length [23], osteogenic effect, trabecular thickness, bone density, bone volume, and osteogenic markers using different techniques [3,6,9,13,[24][25][26]. The number of animals used in the study experiments ranged from 13 to 206.…”

“…However, for use in dentistry, vibrations have, in the first instance, been classified into low frequency vibrations (LFV), which are ≤45 Hz, and high frequency vibrations (HFV) which represent frequencies ≥90 Hz [6] but, independently, the frequency used and its use in orthodontics has focused on taking advantage of catabolism to accelerate tooth movement [3,7,8]. Although they have also been used to reduce post-treatment pain, in this work, we have concentrated on analyzing the possible use of their anabolic effect to prevent post-treatment relapse [9,10]. To this end, it is important to mention that the literature describes its anabolic effect because of the presence of Ruffini type I receptors that convert the bone tissue into a mechanosensitive medium, easily adaptable to this type of stimuli [11,12].…”

Mechanical vibrations have a biphasic effect depending on the context in which they are applied; their anabolic action has been used in medicine to increase bone density. In dental specialties such as orthodontics, their catabolic effect during mechanical compression has been widely studied, but the anabolic effect of vibrations is less investigated, so it is important to carry out research to clarify the effect of vibrations on the alveolar bone, explore a new approach to its use in orthodontics, and the increase of post-treatment bone density to prevent relapse. Hence, this work aims to systematically review the literature to evaluate the evidence regarding vibratory stimulation and its anabolic effects on alveolar bone in animal models. Methodology: A systematic review followed the PRISMA guidelines in PubMed, Scopus, and Web of Science databases. With the PICO strategy, we formulate the subsequent research question: Does the application of vibrational force induce an anabolic effect in the alveolar bone of animal models? Due to the lack of human studies, the population of interest was animal models; only articles where mechanical vibrations were the intervention method and the alveolar bone density or osteogenesis were evaluated and included. The selected studies underwent quality and risk of bias assessment through ARRIVE and SYCRLE instruments, respectively. This protocol was registered in INPLASY, under ID number: 202280103. Results: All eight articles included in this work demonstrate that applying low and high frequency vibrations increases the osteogenic effect by increasing the density and volume of bone tissue and increasing the expression of osteogenic markers. The included studies present a medium quality and risk of bias. Conclusion: It is important to highlight that, regardless of the protocol used, low or high frequency vibrations increase bone density, particularly in the alveolar bone, since this is the bone of interest in orthodontics. These promising results set an important precedent for the design of experimental protocols but now in the context of post-orthodontic treatment in humans.
