Plain English Summary
Background and study aims
Orthodontic mini-implants are very small (1.5 – 2 mm wide) customised titanium alloy screws which acts as an anchor point in the jaw. Mini-implants are frequently placed between the roots of teeth, but may also be sited in the roof of the mouth. They are then connected to a fixed brace to help move the teeth.
Orthodontic Mini implants is a procedure which is currently popular and commonly used to reinforce anchorage need in an orthodontic treatment. Despite it resulting in absolute anchorage, there are issues (of varying percentages) related to its usage such as pain due to insertion and impingement of the MI head to the buccal mucosa and ulceration, implantitis and failure of the MI to name a few.
Thus the aim of this study is to look further into this matter by means of RCT. The main aim of this study is to evaluate the pain score of patients who are treated with different methods.
Who can participate?
Adult orthodontic patients aged 18 - 30 years, requiring MI placement as part of anchorage reinforcement of their orthodontic treatment, and in good health.
What does the study involve?
Participants will be randomly allocated to receive orthodontic mini implants using three different methods and will be followed up for 30 days.
What are the possible benefits and risks of participating?
The use of the MI covers have shown to help reduce the pain levels in the subjects. The MI covers can be used as a method to help reduce pain and discomfort for patients, by protecting the tongue, cheek and lips from mucosal injury and trauma which could lead to ulceration.
Where is the study run from?
University Teknologi MARA (UiTM), Jalan Hospital Postgraduate Orthodontic Clinic (Malaysia)
When is the study starting and how long is it expected to run for?
Who is funding the study?

Clinical assessment of orthodontic mini-implant covers and their effect on oral health quality of life: a randomised controlled trial
1. There will be a difference in the pain level and discomfort in all the three groups (Control, Soft Flow and Composite resin)
2. There will be a difference in the occurrence of ulceration in all the three groups (Control, Soft Flow and Composite resin)
3. There will be a difference between the subject’s Oral health-related quality of life (OHRQoL) in all the three groups with or without the MI covers (Control, Soft Flow and Composite resin)
4. There will be a difference in the cost-effectiveness between the mini implant covers used (Soft Flow and Composite resin groups)

Oral health (orthodontic)
The patients will be allocated randomly by stratified block randomisation. Recruited patients will be active orthodontic patients that require orthodontic mini implants (MIs) as part of their orthodontic treatment plan.
Three groups involved will be:
1. Control group
2. Soft flow group (SF)
3. Composite resin (CR) group
Only the SF and CR groups receive interventions in which the Soft flow material or the Composite resin material will be placed on the MI head after the MI insertion. The parameters observed will be the Pain score, oral health impact profile and cost-effectiveness of the MI covers as well as the MI failure. The nine different time points are: B0 (baseline- before MI insertion for Control group) and T0 (immediately after MI insertion fr SF and CR groups); T1 (1 hour after MI insertion); T12 (12 Hours after MI insertion); T24 (24 hours after MI insertion); TD2 (2 days after MI insertion); TD3 (3 days after MI insertion); TD7 (7 days after MI insertion); TD14 (14days after MI insertion) and TD30 (30 days after MI insertion).
Primary outcome measure
Pain score (Numeric Rating Scale) at T0-TD30 at B0 (baseline- before MI insertion for Control group) and T0 (immediately after MI insertion fr SF and CR groups); T1 (1 hour after MI insertion); T12 (12 Hours after MI insertion); T24 (24 hours after MI insertion); TD2 (2 days after MI insertion); TD3 (3 days after MI insertion); TD7 (7 days after MI insertion); TD14 (14days after MI insertion) and TD30 (30 days after MI insertion)
Secondary outcome measures
1. Oral health-related quality of life using the Modified Short Oral Health Impact profile -14 (at T0 and TD30)
2. Cost-Effectiveness of the MI covers calculated by comparing the current the cost of each material (per syringe) and the amount of MI covers that are produced by a single syringe

Results and Publications
Publication and dissemination plan
The publication plan is to divide the trial in 2 parts (two publications). The first part is to report the primary findings on the pain scores and the occurrence of ulceration as well as the dislodgement of the MI covers and cost effectiveness. The second part is to report on the secondary findings which is the oral health impact profile.
