Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Techniques

Background:

  • Impacted mandibular third molars are common, often requiring surgical extraction.
  • Various flap designs are used for this procedure, each with potential advantages and disadvantages.

Purpose of the Study:

  • To evaluate the distal-triangular flap as a practical surgical approach for mandibular third molar extraction.
  • To compare its efficacy and patient outcomes against traditional Szmyd and envelope flaps.

Main Methods:

  • A prospective study involving 60 participants with impacted mandibular third molars.
  • Random assignment to three groups: distal-triangular flap, Szmyd flap, or envelope flap.
  • Postoperative assessment of pain, swelling, mouth opening, and periodontal status over three months.

Main Results:

  • All 60 participants underwent successful extraction with no postoperative infections or neurological complications.
  • No statistically significant differences were observed in pain, swelling, mouth opening, or periodontal status among the three flap groups (P>0.05).

Conclusions:

  • The distal-triangular flap is a safe and reliable alternative for mandibular third molar extraction.
  • It offers advantages in operative field exposure and requires less patient mouth opening.
  • This flap design is a viable option for oral surgeons.
