Piezoelectric bone surgery for impacted lower third molar extraction compared with conventional rotary instruments: a...

Area of Science:

• Oral and Maxillofacial Surgery
• Surgical Technology

Background:

• Impacted lower third molar extraction is a common surgical procedure.
• Conventional rotary instruments are widely used but associated with potential complications.

Purpose of the Study:

• To compare piezoelectric bone surgery (PBS) with conventional rotary instruments for impacted lower third molar extraction.
• To evaluate the impact of PBS on surgical time and intra- and postoperative complications.

Main Methods:

• A meta-analysis adhering to PRISMA guidelines.
• Screening of PubMed, Embase, Scopus, and OpenGrey databases (1990-2018).
• Inclusion of randomized controlled trials (RCTs) comparing PBS and rotary instruments.

Main Results:

• Strong evidence indicates PBS prolongs surgical duration.
• Low evidence suggests PBS reduces postoperative morbidity (pain, trismus).
• Insufficient data on neurological complications and swelling.

Conclusions:

• PBS may offer benefits in reducing postoperative pain and trismus.
• PBS might increase surgical time compared to rotary instruments.
• Further research is required to clarify the efficacy of PBS for other complications.
