Corticotomy-facilitated orthodontics using piezosurgery versus rotary instruments: an experimental study.

Area of Science:

• Orthodontics
• Periodontal Surgery

Background:

• Corticotomy-facilitated orthodontics (CFO) is a technique to accelerate tooth movement.
• Piezosurgery and conventional rotary instruments are used for corticotomy procedures.

Purpose of the Study:

• To compare the efficacy of piezosurgery versus conventional rotary instruments in corticotomy-facilitated orthodontics.

Main Methods:

• A split-mouth study was conducted on ten dogs comparing piezosurgery and conventional rotary instruments for mandibular premolar retraction.
• Tooth movement was measured monthly for six months using a sliding caliper.
• Histological evaluation was performed post-sacrifice to assess tooth movement.

Main Results:

• Conventional rotary instruments showed a statistically significant higher mean amount of tooth movement compared to piezosurgery at all measured intervals.
• The rate of tooth movement was consistently greater with the conventional rotary technique.

Conclusions:

• Corticotomy-facilitated orthodontics using conventional rotary instruments is more effective in accelerating tooth movement than using piezosurgery.
• Tooth movement was observed to be 1.6 times faster with conventional rotary instruments.
