Summary
Surgically assisted rapid maxillary expansion is safer than orthopedic expansion for preventing gingival recession. This orthodontic treatment effectively expands the upper arch with fewer mucogingival problems.
Area of Science:
- Dentistry
- Orthodontics
- Periodontology
Background:
- Maxillary transverse diameter expansion is a common orthodontic treatment.
- Concerns exist regarding its association with gingival recession.
Purpose of the Study:
- To compare the incidence of gingival recession between surgically assisted rapid maxillary expansion (SARME) and orthopedic expansion (OE).
Main Methods:
- Two patient groups underwent either SARME or OE.
- Maxillary transverse dimensions were measured.
- Incidence of gingival recession on upper premolar/molar teeth was assessed and compared using a chi-squared test.
Main Results:
- Both SARME and OE successfully expanded the maxillary transverse dimension (5.3 mm and 4.4 mm, respectively).
- Gingival recession occurred more than twice as frequently in the OE group compared to the SARME group.
- The difference in recession incidence between the two groups was statistically significant (chi-squared test).
Conclusions:
- Surgically assisted rapid maxillary expansion is an effective orthodontic procedure for increasing maxillary transverse diameter.
- SARME appears to be a safer alternative to orthopedic expansion concerning the risk of developing mucogingival problems, specifically gingival recession.
