smart moves® exceed® is a patented suite of precision computer-aided
bracket placement solutions. This exclusive technology determines the
exact digital placement coordinates for each bracket. Then, through the
use of cutting-edge 3D model printing technology, bonding trays are
manufactured with unrivaled fit and bracket position accuracy.
exceed Provides Unprecedented Accuracy -
Powerful software scientifically calculates the ideal position of the brackets on the teeth:
Outcomes are more predictable and consistent
Adjustments to brackets and archwires are minimized or eliminated
Patient satisfaction is increased
exceed Offers Two Different Methods to Calculate Ideal Bracket Positioning
exceed Rx: Position of appliances is individualized using the pre-treatment occlusion
exceed
Tx: Position of the appliances is optimized to fit a
virtual post-treatment setup
exceed is Fast and Efficient -
exceed significantly reduces time spent placing
brackets
exceed minimizes chair time and increases patient comfort
exceed Gives You Ultimate Control -
Prior
to tray fabrication, a virtual model will be available for your review
and approval. The user-friendly software will allow you to adjust the
bracket placement, giving you ultimate control.
We can use your brackets or you can select ours. exceed is compatible with most popular straight-wire bracket systems.
Note: Bonding tray is fabricated with clear/soft and clear biocryl materials only.
Accurate impressions with any type of impression material are acceptable
Impressions must adequately reflect all relevant anatomy
Impression material must not be separating from the impression tray
Consider pouring your models right away if your impressions are moisture, temperature, or time sensitive
Impressions sensitive to moisture content should be wrapped in a damp paper towel and placed in a sealed plastic bag if models are not poured immediately
Only metal impression trays and those with VPS impression material will be returned
The nature of impression materials currently on the market may contribute to common model problems encountered in the laboratory. Have you encountered porosity (bubbles, voids) or poor surface quality? Plaster or stone mixes are water based and they interact with impression surfaces in a water-like manner. Liquids placed on solid surfaces will be either attracted to, or repelled from that surface in varying degrees. Please be aware when selecting impression material if it is hydrophilic or hydrophobic.
Hydrophilic: is attracted to, or can be wetted by water. Hydrophobic: is when liquid is repelled or fails to bond with liquids. Vinyl poly siloxane (VPS) options can be hydrophilic or hydrophobic. Alginate is hydrophilic.
There are advantages and disadvantages to these impression options but there are products on the market to help reduce the disadvantages. Surfactants and debubblizer sprays can be used to lower surface tension between surfaces making the impression material more hydrophilic and assure a better impression result.
Great Lakes carries ACU-flow™ a VPS impression material which is hydrophilic and requires NO surfactant spray for surface tension reduction, eliminating bubble formation. Surfactants must be used properly and excess surfactant should not be allowed to pool in the cusp tips. This can cause loose, sandy-like cusp tips. Excess surfactant needs to be blown out leaving a wet look only before pouring.

Models:
Plaster or stone models are acceptable. Generally, the durability of stone is preferred.
Models should be reasonably trimmed, yet sufficiently thick for strength considerations.
No horseshoe-shaped models; Models should have a base of at least 7mm in the thinnest area.
Bases will be added as necessary (for an additional fee) to models without bases or those lacking adequate base thickness or strength.
Please indicate if your model must be duplicated as work models may get damaged during the appliance fabrication process.
Bite Records:
Please package bite registrations carefully.
Bite records must not be left between models for shipment to the lab.
Dedicated packaging should be considered for brittle materials such as Delar wax.
Please identify the nature and the intent of each bite record, if more than one is being supplied.
Please consider mounting the maxillary model, before sending it to the lab, for those cases requiring mounting. Sending items such as facebows, bite forks, and mounting jigs through the mail often results in unreliable mountings.
