简要总结

The objective of this study is to compare the canine retraction rate (in mm with a 100 mm marked scale) using Ni-Ti closed-coil springs versus elastomeric power chains during canine retraction in subjects with first premolar extractions over a period of three months.

After the extraction of all first premolars under local anesthesia. For canine retraction, Ni-Ti closed-coil springs and elastomeric power chains will be randomly allocated to the right and left quadrants of both arches.

Radiographic measurement (root resorption) and clinical measurements (canine retraction, plaque accumulation and gingival health) will be recorded at four points in time. First, at the start of the canine retraction (T0), after first month (T1), second month (T2) and third month follow-up (T3).

详细描述

RATIONALE:

Premolar extraction followed by canine retraction is one of the common practices in orthodontics to treat malocclusion such as severe crowding and proclination of anterior teeth. It is essential to know methods and techniques that result in minimum or no adverse effects on roots of teeth and periodontal health. This will help the clinicians to choose the best method that will result in a faster and more physiological closure of extraction spaces. Moreover, to the best of our knowledge, limited studies have compared the effects of Ni-Ti closed-coil springs and elastomeric power chains on canine root resorption, gingival health and plaque accumulation. It is necessary to establish a comparison between these methods, as it can help clinicians to provide better care and enhance the overall effectiveness of orthodontic treatment.

OBJECTIVE:

Primary Objective: The objective of this study is to compare the canine retraction rate (in mm with a 100 mm marked scale) using Ni-Ti closed-coil springs versus elastomeric power chains during canine retraction in subjects with first premolar extractions over a period of three months.

Secondary Objective: This study will also include an assessment of canine root resorption (in mm using periapical radiograph), dental plaque accumulation and gingival health (according to indices mentioned below with CPI-TN probe) using Ni-Ti closed-coil springs versus elastomeric power chains during canine retraction in subjects with first premolar extractions over a period of three months.

结局指标

主要结局

Canine retraction rate

时间窗: 3 months

The retraction rate of canine will be the distance travelled divided by the time interval needed for closure of spaces. It will be noted at four-time intervals i.e at the start of the canine retraction (T0), after first month (T1), second month (T2) and third month follow-up (T3).

次要结局

  • Root resorption(3 months)
  • Gingival health(3 months)
  • Plaque index(3 months)
