Sperimentale: Insertion with self-drilling technique
Each patient received two microimplants both using self- drilling method.
In accordance with the principles of a randomized controlled trial, the choice between the self-drilling and self-tapping techniques was alternated between patients by a flip of a coin performed by a dental assistant.
|
Patients received 2 miniscrews using self-drilling method. The same orthodontist (M.S.) performed all the insertion procedures. Miniscrews were always placed at the junction of the attached mucosa and alveolar gingiva, between teeth 15 and 16, and between teeth 25 and 26, in accordance with the Wrocław protocol guidelines. The investigated complications were:

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Assessing the presence of peri-implantitis
Lasso di tempo: The occurrence of inflammation was recorded during subsequent follow-up visits (first 2 weeks after implantation and then every 6 weeks, until the distalization was completed, assessed up to 12 months).
|
Hypertrophy of the gingiva and/or redness and/or tendency to bleed was noted as the inflammation presence.
|
The occurrence of inflammation was recorded during subsequent follow-up visits (first 2 weeks after implantation and then every 6 weeks, until the distalization was completed, assessed up to 12 months).
|
|
Assessing the presence of pain lasting longer than 48 hours after implantation.
Lasso di tempo: 2 weeks after implantation
|
Two weeks after the miniscrew implantation patients were surveyed upon pain incidence lasting longer than 48 hours.
|
2 weeks after implantation
|
|
Assessing the presence of root perforation
Lasso di tempo: Immediately after implantation
|
Root perforation was diagnosed in CBCT performed after the procedure.
|
Immediately after implantation
|
|
Assesing the presence of microimplant fracture
Lasso di tempo: During implantation
|
Microimplant fracture was diagnosed during implantation, reported by the clinician.
|
During implantation
|
|
Assessing the stability of miniscrews
Lasso di tempo: During subsequent follow-up visits, until the distalization was completed, assessed up to 12 months.
|
The mobility of the miniscrews was checked clinically with cotton tweezers at each visit.
Miniscrews that could not sustain orthodontic force and required replacement because of mobility were considered failures.
|
During subsequent follow-up visits, until the distalization was completed, assessed up to 12 months.
