How It Works

The Denovo Pediatric Chairside Space Maintainer System saves you time and money

Primary dentition plays an important role in pediatric dentistry. Premature loss or extraction of primary molars can have significant detrimental effects because of tooth drift. Maintaining space is critical, but it requires early and quick intervention. Traditional methods involve multiple appointments, impressions, and significantly time-consuming and expensive custom lab work.

The Denovo chairside space maintainer system streamlines the process of creating and installing a custom unilateral, band and loop space maintainer. You can complete this 3-step process chairside in just minutes with only one patient visit while the patient is still numb from extraction:

— first, trial fit a Space Maintainer band or crown.
— Second, insert a wire, size to the gap & crimp the tubes.
— And then finish by cementing the appliance in place.

No more dealing with the time-consuming hassle of multiple appointments and expensive lab devices! With the Denovo chairside space-maintainer system you can quickly guide the way for erupting permanent teeth, resulting in an efficient workflow, healthy smiles and happy patients.

Denovo’s Original Universal Chairside System

Based on the original system developed by Dr. Gerber for Unitek®, the Denovo system includes all of the components needed to fabricate a custom unilateral appliance completely chairside. The system consists of preformed molar bands with pre-welded tubing. Bands gradually increase in size and are formed in Maxillary and Mandibular anatomy to perfectly fit any tooth you might encounter. The system includes wires (or loops) of different types that slide into the pre-welded tubing at the required length. Once crimped into place, the fitted device is complete and ready to place.

The Denovo custom unilateral band and loop space maintainer device performs just as, if not more effectively than a tradition lab fabricated band and loop, but at a fraction of the cost with only one appointment! With this system, Dentists can effectively address unilateral primary space loss and minimize tooth drift in virtually every presented case.


Start by selecting 1 to 3 approximate band or crown sizes from the Denovo Space Maintainer kit and then trial fit them to the tooth neighboring the space. A properly fitted band will slide onto the tooth with a tight, snug fit. The stronger the fit, the more durable the device will be. If you trial size a band but do not fully place it, you should sterilize the band and put it back into the kit for future use.

Wires widths are narrow or wide to match the smaller and larger band or crown size ranges respectively. We color-code band sizes in the kit according to the matching wire. Select the wire type based on the clinical situation presented:
– Drop wires: curve upward to prevent drifting of the wire into the gingiva.
— Plain wires: are highly customizable, with the ability to adapt to most clinical situations.
— Occlusal rest wires: provide added stability and support by bending over the occlusal ridge.
— Distal Shoe: With proper placement and x-ray verification, you can seat distal shoe wires sub-gingivally if the first permanent molar has not fully erupted yet.

Trim the chosen wire (as necessary) and then insert into the tubes. Re-seat the appliance and slide the wire across the gap to save the space. Adding curvature to the loop to the natural contour of the gingiva helps prevent the wire from drifting into the gingiva. Apply a solid, circular crimp to both tubes to firmly lock the wires into place. Finally, cement the finished device into place using your preferred glass ionomer cement.

Kits come with everything you need to get started. 78 S/M band full and half sizes are separated by size into maxillary and mandibular trays. Trays are slotted for easy identification and picking of sizes. Each tray also has an assortment of narrow and wide wires. Kits come with the Denovo tube crimping plier, for securely crimping the tubes around the wires.

Get started with the introductory space maintainer kit, with 1 band of each size.

Or, you can find the professional space maintainer kit here, with 2 bands of each size.

Comparison to traditional methods and labs:

Maintaining space is critical for setting up a child’s mouth for successful development. But it requires early and quick intervention. Traditional methods involve impressions, time-consuming and costly custom lab work, and scheduling multiple appointments. But all the time between appointments, re-scheduling and no-shows can lead to substantial tooth drift and additional interventions.

Chairside space maintainers solve all of these issues, allowing Dental professionals to address the issue directly after extraction without the need for a follow up appointment. Studies and surveys show that the custom band and loop is equally as sturdy and effective at maintaining space as a lab fabricated device. In addition, the cost savings compared to lab-fabricated devices is significant, with each denovo space maintainer costing only $10-$13. This system can cut your costs by as much as 50% while providing your patient with the most effective treatment available.
