Objectives To investigate the influence of micro-osteoperforation (MOP) on rate of orthodontic tooth movement and pain perception with fixed appliances. Design 2 arm parallel randomized controlled trial with an allocation ratio of 1:1. Setting The outpatient department of a dental college. Participants 105 patients were screened, out of which 60 met the inclusion criteria and consented to participate; consisting of 33 females and 27 males requiring en-masse retraction following first premolar extractions. Methods The experimental group consisted of patients bonded with a fixed appliance (Gemini 3M) who received MOP distal to canines throughout the period of retraction every 28 days. These were compared with a control group treated with identical brackets without MOP and were assessed for rate of tooth movement (canine retraction) and pain perception using a Visual Analogue Scale (VAS) of 10 mm. Results Prior to commencement, all baseline parameters were matched between the two groups (p>0.05). A statistically significant increase in rate of tooth movement in the MOP group (p<0.05). Conclusion MOP appears to enhance the rate of tooth movement with no differences in pain perception.
Objectives To examine the effect of micro-osteoperforation (MOP) on the space closure rate using passive self-ligating or conventional brackets. Materials and Methods This was a two-arm parallel randomized controlled trial undertaken at the outpatient department of a dental college. There were 60 participants (30 women and 30 men) who fulfilled the inclusion criteria. Both the study and control groups were subjected to MOPs throughout the period of space closure. MOPs were repeated every 28 days. The experimental group (mean age 19.5 ± 1.66 years) was bonded with passive self-ligating brackets while the control group (mean age 19.9 ± 1.13 years) was bonded with conventional brackets. Both groups were examined and compared for rate of space closure. An evaluation was conducted for both groups until the entire extraction space was closed and confirmed by evaluation of a tight contact between the canine and the second premolar using a piece of dental floss. Results Before the initiation of retraction, all initial criteria were similar between the two groups (P > .05). No difference was observed between the two groups in the rate of space closure (P > .05). Conclusions MOP in conjunction with passive self-ligation does not increase the rate of orthodontic space closure when compared with MOP used with conventional brackets.
Prevention of unwanted post-treatment changes remains one of the biggest challenges in orthodontics. Retention using removable appliance is important, which can alter the oral hygiene and oral microbial flora, overall increase in the Streptococcus mutans can lead to caries formation which can lead to a missing tooth that can spoil the overall appearance of the patient. 24 post orthodontic subjects were divided in to two groups and group I was given Essix retainer and Group II was given Hawleys Retainer, Supra gingival plaque collected and bacterial colony count done using digital colony counter OHI-S and PI are recorded at T0 (start of treatment) T1 (30 days) T2 (60 days). Essix group has a significant increase in the streptococcus mutans count OHI-S and PI scores are higher for hawleys retainer group. This study advocates the use of a better appliance which along with aesthetics can also ensure better oral hygiene Care should be taken to provide detailed hygiene instructions for both appliance and teeth.
: Online businesses that actively promote DIY (Do it yourself) aligners and DIY braces on social media have caused a significant shift in patient attitudes toward orthodontic treatment in particular. With the development of 3D printing and aligner technology, DIY orthodontics made the transition to home aligners/DIY aligners, in which patients were asked to send dental impressions on a preselected tray or have their homes scanned by non dental professionals, who then made the appropriate aligners without undergoing a clinical and radiographic evaluation by a qualified orthodontist To conduct a survey between general dental practitioner and orthodontists assessing the esthetic outcomes of pre and post orthodontic treatment photographs posted by DIY aligner companies in their website. 15 random pre and post treatment photographs posted by DIY aligner companies for their promotion in their websites were chosen. Also, 15 random pre and post treatment photographs were chosen from professionals. These photographs were jumbled and a comparative survey to assess the esthetic perception of 110 general practitioners and 110 orthodontists with the help of Likert’s scale was created and sent via Google form to them. Descriptive statistics was obtained from google form; the results obtained were statistically analysed with Chi-Square test. Likert’s scale favoured the photographs of treatment rendered by Professionals and were considered as best. Although, DIY aligners may sound attractive and cost effective, when compared to the therapy provided by orthodontists, it causes substantial and permanent damage to the tooth and gums, as well as being cosmetically unappealing.
Orthodontics in its century of existence have had a lot of landmarks in its evolution, but very few can match the clinical impact made by micro-implants and the recently introduced infra-zygomatic crest & buccal shelf orthodontic bone screws. Micro-implants and extra-radicular BS have brought about a renaissance to the field of orthodontics with its concept of absolute anchorage in the past decade. It is an added armamentarium in the hands of an experienced clinician to overcome new clinical challenges and convert even borderline surgical cases to nonsurgical without, compromising with the results achieved. Aim It is a FEM study in which buccal shelf screws are inserted in buccal bone lateral to the distal root of the 2nd molar and 4 mm buccal to the CEJ with different retraction forces and various angulation to study stress pattern in MBS area. Material and Method CBCT 3D image of the study mandible is made and the image transfer to the software. A FEM is created using a dedicated software. Orthodontic buccal shelf screws which is made of titanium alloy (diameter, 2 mm; length, 12 mm; thread ridge height, 0.2 mm; thread pitch, 0.6 mm). Miniscrew implant insertion is designated at 30°, 40°, 60°, 70°, and 90° angulations, and at each angulation a horizontal load of 150, 200, and 250 g is applied. Results BSS when inserted in buccal bone 60-70 degree angulation showed the least stress pattern in mandibular buccal shelf area and 40 – 50 degree angulation showed maximal stress distribution pattern.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
