The cement can be mixed according to the manufacturers instructions. However, if you mix the cement so that it is sufficiently viscous, it will adhere to the inside of the band during placement and cementation and not cause difficulty by "running all over." Some clinicians stick a small section of masking tape over the band to prevent escape (i.e., "running") of the cement. This technique is fine if it works well for you. However, a slightly thicker mix of cement will prevent escape of the material in the first place.

Once the appliance is cemented in place, remove the excess cement. One other advantage of the newer generation cements is that they are much handier when it comes to cement removal than the older generation cements.

Have the patient bite together one last time to insure that the appliance is not interfering with the occlusion.

It also is a good idea to show the appliance to the parent. Emphasize the importance of keeping the area clean. At this time, you can mention any potential issues about the space maintainer that you choose, in addition to re-emphasizing the importance of hygiene. For example, soreness for approximately twenty-four hours can occur. The child should avoid "playing" with the appliance with the tongue, which also can cause soreness (of the tongue). Temporary speech changes can occur with some appliances (especially Nance Appliances), but it is important to emphasize that the changes are temporary. In very unusual cases, short-lived sleep changes can occur, but once again these problems are transitional (and indeed very rare).

Many clinicians appoint patients who have had space maintainers placed for a quick check-up visit after approximately two-four weeks.
