Le Fort I osteotomy and maxillary interdental osteotomy showed minimal marginal bone loss in patients with good oral hygiene. Clinical relevance was not observed, but results may differ in patients with pre-existing bone loss.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthodontics
  • Periodontology

Background:

  • Dentofacial deformities often require surgical correction.
  • Le Fort I osteotomy and interdental osteotomy are common procedures.
  • Assessing impact on marginal bone level is crucial for long-term stability.

Purpose of the Study:

  • To evaluate the effect of Le Fort I osteotomy and maxillary interdental osteotomy on marginal bone levels.
  • To determine if these surgical interventions lead to clinically significant bone loss.

Main Methods:

  • Retrospective radiographic analysis of 40 patients (mean age 24) undergoing Le Fort I osteotomy with or without interdental osteotomy.
  • Marginal bone levels were measured pre-operatively and 1 year post-operatively.

  • Patients maintained good oral hygiene throughout the study period.

    • Main Results:

    • Overall mean marginal bone loss of 0.2 mm was observed at surfaces without interdental osteotomy (P=0.001).
    • Significant bone loss was noted for central incisors (0.5 mm) and canines (0.4 mm).
    • Interdental osteotomy resulted in 0.4 mm mean bone loss, not significantly different from no interdental osteotomy (P=0.07).
    • Premolars showed significant bone loss (0.3 mm, P=0.04) after interdental osteotomy.
    • Despite statistical significance, bone loss was not clinically relevant.

    Conclusions:

    • Le Fort I osteotomy and interdental osteotomy generally result in minimal marginal bone loss.
    • Clinical relevance of bone loss is unlikely in patients with good oral hygiene.
    • Findings may not apply to patients with pre-existing compromised marginal bone levels.
