Purpose:
The purpose of this retrospective study was to demonstrate differences in choices in space maintenance when performing extractions utilizing different behavior guidance techniques. We hypothesize that advanced behavior guidance techniques influence different space maintenance choices than basic techniques.

Methods:
Data were collected from axiUm electronic patient records. Patients ages 4-8 whose records included extraction were included in the study and assigned to one of two groups: 1) extraction under general anesthesia or 2) extraction with nitrous oxide. Records were reviewed to determine type of space maintainer and date of placement.

Results:
Preliminary analysis considered single tooth extractions. Of 100 patients with extraction under general anesthesia, 88 (88%) had space maintainers delivered the same day and 12 (12%) on a different date. Of 128 patients with extractions with nitrous oxide, 55 (43%) had space maintainers delivered the same day and 73 (57%) on a different date. Pearson's chi-squared test demonstrated statistically significant differences between the two groups (P <0.01). Further quantitative and qualitative analysis is to be performed with an expanded dataset.

Conclusions:
Patients undergoing extractions under general anesthesia are much more likely to have a space maintainer placed the same day compared to those treated with nitrous oxide. Pre-fabricated space maintainers make same day placement more feasible than their lab-fabricated counterparts when utilizing advanced behavior guidance techniques.
