An Innovative Keyhole Trephine Technique for Deep-Seated Impacted Mandibular Molars: A Technical Note

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Regenerative Dentistry

Background:

• Surgical removal of deeply impacted mandibular third molars presents challenges.
• Conventional techniques may lead to significant bone loss.
• Need for minimally invasive and bone-preserving extraction methods.

Purpose of the Study:

• To present an innovative surgical methodology for impacted mandibular third molar extraction.
• To highlight the advantages of using a trephine bur in this procedure.
• To demonstrate the use of osteotomized bone as an autologous graft with biomaterials.

Main Methods:

• Surgical removal of impacted mandibular third molars using a trephine bur.
• Preservation of osseous structures during osteotomy.
• Utilization of the osteotomized bone segment as an autologous graft.
• Supplementation of the graft with beta-tricalcium phosphate and hydroxyapatite.

Main Results:

• The trephine bur technique allows for precise bone sectioning.
• Preservation of surrounding bone architecture is achieved.
• The osteotomized bone segment serves as a viable autologous graft.
• Integration of biomaterials enhances graft composition.

Conclusions:

• The trephine bur methodology offers an innovative approach to impacted mandibular third molar surgery.
• This technique facilitates bone preservation and effective graft utilization.
• The described method holds potential for improved patient outcomes in third molar extraction.
