Inflammation Caused by the Placement of a Temporary Anchorage Device

Brief summary
To determine if coating miniscrews with K21 would increase the success rate of orthodontic miniscrews by reducing adjacent tissue inflammation.
Detailed description
The study design is a split mouth study where 2 miniscrews, one pretreated with K21 the other pretreated (experimental) with ethanol (placebo) are placed in the mouth for orthodontic therapy. All participants will receive 2 or more orthodontic miniscrews with equal numbers of experimental and control pretreatment solutions. Mobility will be assessed at the 4 and 8 week follow up appointments by gentle manipulation with cotton pliers. Clinical success will be defined as maintenance of stability for a period of 8 weeks. Peri-implant inflammation will be assessed at follow up appointments by looking for signs of soft-tissue inflammation (redness, swelling) where possible.
Interventions
K21 Cavity cleanser is rinsed over the TAD and allowed to dry. The TAD is placed where needed for orthodontic therapy following the Department of Orthodontics protocols.
Ethanol is rinsed over the TAD and allowed to dry. The TAD is placed where needed for orthodontic therapy following the Department of Orthodontics protocols.

Study design
Masking description
There will be random allocation established, such that as a study participant is enrolled the clinician will receive a numbered envelope that contains the information for which TAD placement site will receive a TAD coated with solution A or B. The identification of Solution A or B is kept secret in an envelope stored in the office of the Chair of the Orthodontic Department (U Colo, Sch Dent Med). The patient, clinical operator, Investigator and Outcomes assessor is not aware which solution (A or B) is the experimental or placebo.

Eligibility
Inclusion criteria
1. Good general health, with no significant medical findings 2. Requiring at least two miniscrews in their treatment plans (i.e., most participants will have two miniscrews, but some may receive four or six as indicated by their individual treatment plan) 3. Miniscrew pairs indicated with comparable anatomical positions and comparable mechanics (direct vs. indirect anchorage).
Exclusion criteria
1. Recent or ongoing use of antiresorptive pharmacological agents contraindicating the use of orthodontic miniscrews 2. Less than 12 years of age 3. Heavy tobacco use (\>10 cigarettes/day) 4. Peri-implant tissues must be observable at follow-up appointments 5. Being unable or unwilling to consent to the study
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| TAD motility | 8 weeks | The motility of a TAD is evaluated by gentle manipulation with cotton pliers. Clinical failures will be defined as a mobility greater than or equal to 1mm. Clinical success will be defined as maintenance of stability for a period of 8 weeks. |
| Peri-implant inflammation | 8 weeks | Inspection for signs of soft-tissue inflammation (redness, swelling) immediately around the TAD. The Loe-Silness Index scale will be used to assess any inflammation. The Loe-Silness Index scale is between 0 and 3 where a 0 is normal soft tissue, 1 is mild inflammation where the tissue color is slightly red and the tissue does not bleed upon probing, 2 is moderate inflammation where the tissue color is red with edema and bleeds upon probing, and 3 is severe inflammation where the tissue bleeds with little or no probing has edema and has ulcers. |
