Evidence indicates minimal short-term space loss after premature loss of primary first molars
Greg Huang DMD, MSD, MPH; Jacob DaBell DDS
Systematic Review Conclusion
The reported magnitude of space loss after premature loss of primary first molars—1.5 millimeters per arch side in the mandible and 1.0 mm per arch side in the maxilla—is not likely to be of clinical significance in most cases.
Critical Summary Assessment
The reviewers’ conclusion was made on the basis of the results of only three studies, which included a total of 70 patients who were followed by investigators for up to eight months.
