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.
Adult orthodontics has gained widespread acceptance recently with the introduction of more esthetic options for the patient. The major deterrent that remains is the prolonged treatment time associated with comprehensive orthodontic treatment. The objective of this paper is to present a review of techniques, which could be employed by the orthodontist in conjunction with a periodontist to enhance the rate of orthodontic tooth movement. The biological rationale and clinical manipulation have been discussed with a brief review of the current literature about these techniques. The interdisciplinary approach involving the orthodontist and the periodontist can benefit the patient by affording them with reduced treatment time.
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.
