<p>Simple space maintainers can prevent adverse mesial movement of molars. The molar position can also be retained to allow use of the leeway space in cases of insufficient arch length. Modifications to the basic space maintainer can allow for minor Simple space maintainers can prevent adverse mesial corrections for molar distilization, or anterior advancement. Retainers can be constructed with lingual removable arch wires for ease of adjustment or for periodic removal and cleaning.</p>

space maintainer with a crib wire is effective on cases where the first and/or second deciduous molars have been lost. It anchors on the tooth mesial or distal of the space, and the horizontal sections of the wire are adjustable to assure&nbsp;<br />
a snug fit.</p>

This appliance affords superior retention without the possibility of loss of anchorage due to exfoliation of deciduous detention. Wire stops can be included to contact the distal of cuspids or laterals thus increasing the anchorage unit.</p>

The lingual wire is contoured to the deepest portion of the vault and an acrylic button is processed to provide stability without compromising hygiene. The appliance illustrated, uses the 3D Modular fixed/removable attachment for cleaning.</p>

Opening the loops individually can provide slight distal pressure on the molars. Simultaneous activation of both loops can slightly advance the anterior segment. The lingual wire can be constructed to allow the doctor to remove the arch for adjustments without removing the anchor bands. The Mershon attachments shown, incorporated a single post-sleeve arrangement for maximum stability and ease of placement.</p>
