This review found moderate evidence that dental roots contacting intermaxillary screws (IMS) show no clinical changes, but damage depends on the contact level. More research is needed for definitive conclusions on IMS root damage.

Area of Science:

Dentistry
Orthodontics
Oral Surgery

Background:

Intermaxillary screws (IMS) are used in orthodontic and orthopedic treatments.
Potential for iatrogenic damage to dental roots exists with IMS placement.

Purpose of the Study:

To systematically review existing literature on dental root damage associated with intermaxillary screws (IMS).

Main Methods:

Comprehensive literature search of electronic databases (1980-2011).
Inclusion of prospective and retrospective studies assessing root damage and IMS contact.
Independent data extraction and methodological quality assessment of selected studies.

Main Results:

Six studies met the inclusion criteria, with 2 low-evidence and 4 moderate-evidence.

Moderate evidence suggests no clinical root changes upon contact with IMS, contingent on damage severity.

No iatrogenic root injuries were noted in two excluded studies.

Conclusions:

Current moderate evidence indicates minimal clinical impact on dental roots from IMS contact, but severity is a factor.
Further high-quality studies with robust methodologies and adequate sample sizes are necessary to confirm these findings.
Reliable scientific evidence on the effects of IMS on dental roots requires more rigorous investigation.
