Asymmetric outcomes in bilateral maxillary impacted tooth extractions: A case report

Area of Science:

• Oral Surgery
• Dental Imaging
• Anatomical Analysis

Background:

• Maxillary impacted tooth extraction is common but poses risks, including oroantral communications.
• Assessing extraction difficulty and risks for maxillary third molars is challenging for less-experienced surgeons.

Observation:

• A unique case of bilateral maxillary third molar extraction with disparate outcomes was analyzed.
• Cone-beam computed tomography and 3D software were used for digital assessment of anatomical factors.
• Key variables included bone volume/quality, root angulation, sinus mucosal thickness, and a novel 'tegmen bone' metric.

Findings:

• Local anatomical factors significantly influence extraction difficulty and outcomes.
• Digital analysis allowed for precise evaluation of risk factors in a controlled, single-patient scenario.
• The 'tegmen bone' concept offers a new quantitative measure for assessing risk.

Implications:

• Predictive analysis using detailed anatomical assessment can improve surgical planning for complex extractions.
• This approach can help mitigate complications such as oroantral communications.
• Enhanced understanding of local anatomy aids in managing maxillary third molar extraction risks.
