Descrizione dettagliata
According to the American Association of Orthodontists (AAO), the length of comprehensive orthodontic treatment ranges between 18-30 months, depending on treatment options and individual characteristics. In addition, orthodontic treatment time ranges between 25-35 months for extraction therapies, respectively. Reducing orthodontic treatment time is one of the main goals for orthodontists, due to problems such as root resorption, periodontal disease and caries that are associated with prolonged treatment time.
Many techniques have been introduced to accelerate orthodontic tooth movement; surgical and non-surgical. The surgical approach is the most clinically applied and most tested with known predictions and stable results. Surgical approaches usually vary from total block osteotomies to flapless partial corticotomies .In spite of corticotomy-assisted orthodontic treatment efficiency, the invasiveness of these procedures (i.e. requiring full mucoperiosteal flaps elevation) might have limited their widespread acceptance among orthodontists and patients. Therefore, more conservative flapless corticotomy techniques have recently been proposed. These procedures can be accomplished in a reasonably short periods that might produce less pain and discomfort, so we will gain better patient acceptance. Although various techniques of flapless corticotomy have been reported to be successful in practice, scientific evidence for their effectiveness so far has been limited to case series and a few clinical trials, generally with small groups. This study aims to provide some evidence about the efficacy of piezosurgery in a flapless technique to align crowded lower anterior teeth using a parallel-group randomized controlled trial study design.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: Piezosurgery
Piezosurgery will be performed on the anterior lower segment of the dental arch in order to accelerate the correction of mandibular anterior crowding.
|
The device tip will be used to to create small vertical incisions into the cortex of the dento-alveolar process of the lower anterior teeth.

Nessun intervento: Ordinary Alignment
Treatment will be provided to the patients without any surgical interventions.

Lasso di tempo |
|---|---|---|

Duration of tooth alignment
Lasso di tempo: This will be measured at the end of treatment by calculating the time required time (in days) to achieve complete alignment of lower anterior teeth from the first day of treatment and up to 120-150 days of observation
|
This outcome will be measured in 'days'.

|
Change in Tooth Alignment at one month
Lasso di tempo: Little Index of Irregularity will be measured at 30 days after the onset of treatment.
|
This index is measured on plaster study casts of patients' teeth.
The value obtained will be compared to the value obtained at the beginning of treatment.
|
Little Index of Irregularity will be measured at 30 days after the onset of treatment.
|
|
Change in Tooth Alignment at two months
Lasso di tempo: Little Index of Irregularity will be measured at 60 days after the onset of treatment.
|
This index is measured on plaster study casts of patients' teeth.
The value obtained will be compared to the value obtained at the beginning of treatment.
|
Little Index of Irregularity will be measured at 60 days after the onset of treatment.
|
|
Change in Tooth Alignment at last assessment time
Lasso di tempo: Little Index of Irregularity will be measured when a complete alignment is achieved; this is expected between 90 to 120 days after the onset of treatment.
