Reduction in Overall Time with Corticotomy Using Piezosurgery in Orthodontics: A Meta-Analysis of Randomized Clinical...

Area of Science:

• Orthodontics
• Periodontal Surgery
• Dental Technology

Background:

• Decortication of interdental alveolar cortical bone is a procedure aimed at accelerating orthodontic treatment.
• Piezosurgery offers a minimally invasive approach to bone decortication.

Purpose of the Study:

• To evaluate the efficacy of piezosurgery-assisted corticotomy in reducing orthodontic treatment duration compared to conventional methods.
• To assess the impact of patient age and tooth location on treatment time reduction.

Main Methods:

• A meta-analysis was conducted on eleven randomized clinical trials.
• Trials compared piezocision-assisted orthodontic treatment with conventional single-phase orthodontic treatment.
• Orthodontic treatment duration in months was the primary outcome measure.

Main Results:

• Piezosurgery-assisted corticotomy resulted in a significant weighted mean difference of -1.80 months in treatment duration compared to conventional orthodontics.
• No statistically significant differences in treatment time reduction were observed based on patient age or tooth location.
• The reduction in treatment time represents an average decrease of 30.72%.

Conclusions:

• Piezosurgery-assisted corticotomy is an effective method for accelerating orthodontic tooth movement.
• This technique offers a modest but clinically relevant reduction in overall orthodontic treatment time.
• Further research may explore long-term stability and patient-reported outcomes.
