Quad-Tray XL Dual-Arch Impression Tray
The Quad-Tray XL features a full-quadrant design, extended length, and lateral support for precise occlusal detail with every impression.
New from Clinician's Choice, the Quad- Tray XL combines the inflexible aluminum construction, wide customizable arch, and thin distal bar of the original Quad-Tray with the added benefits of an extended-length, fullquadrant design.
By recording cuspid rise, full-quadrant design provides the detailed occlusal information needed to generate the most precise occlusion possible, whether impressing single or multiple teeth. The tray's extended length enables capture of larger cases while also providing more lateral support for increased rigidity and reduced impression flex.
The tray's extended length enables distortionfree capture in cases involving multiple preparations, including small (3-unit) bridges. On the buccal side, as the tray curves toward the anterior, the perforated walls encompass the height of anterior teeth. The enhanced lateral support holds in the impression material, reducing the risk of distortion.
The 13 dentists who evaluated the Quad-Tray XL rated its ability to pick up the entire quadrant (as compared to their current dual-arch trays)'7 as excellent and 6 as very good to good. Four evaluators cited the ability to take a full-quadrant impression as the feature they liked most. 'The length captures the entire quadrant,' said an evaluator who gave the tray an overall rating of very good.
Ease of Use (Adaptability and Patient Comfort)
The Quad-Tray XL's thin distal bar prevents retro-molar pad impingement. Adaptability and patient comfort are optimized by the customizable arch, which ensures an ideal fit, and the attached mesh, which prevents dripping.
Ease of use was rated as excellent by 2 evaluators, as very good by 4, as good by 5, and as fair by 2. 'My biggest concern is that the meshing isn't always secured well in the tray; it slides out when the tray is adapted and doesn't support the impression material,' said a New Hampshire dentist. Another evaluator said the tray was 'well engineered.'
When asked about adaptability, 2 evaluators rated it as excellent, 4 rated it as very good, and 7 rated it as good. Three evaluators found the posterior bar 'a little thick'; 1 said it 'restricts patients from closing into correct occlusion.' Another suggested 'making it a bit thinner so it's easier to place.' Two evaluators cited adaptability as the feature they liked most.
Rigidity and Lateral Support
Rigidity is ensured by inflexible aluminum construction. The Quad-Tray XL's lingual and buccal walls are enhanced to provide a solid lock of the impression material to the tray without impinging on the palate.
Rigidity, identified by 7 dentists as the feature they liked most, was rated as excellent by 10 evaluators, as very good by 2, and as good by 1. Comments included: 'It helps to eliminate distortions,' 'It's a solid tray,' and 'I loved the rigidity, which is usually difficult to find with triple trays'great product!'
When asked to compare the tray's ability to provide lateral support to their current dual-arch tray, 6 dentists rated the tray as excellent, 5 rated it as very good, and 2 rated it as good. One evaluator, who is 'used to sideless trays,' reported 'a little difficulty with placement in smaller mouths.' Another dentist said the sides 'keep the material firmly in place.'
When asked about the overall effectiveness of the Quad-Tray XL, evaluator comments ranged from 'a little too big and cumbersome'others are more comfortable and just as effective' to 'a bit wide for my taste but this is the goto tray for situations that call for it.'
'The tray is huge, which is absolutely great for very select cases,' said 1 evaluator. Another evaluator reported, 'My crowns came back needing little or no adjustments.'
Overall satisfaction was rated as excellent by 2 evaluators, as very good by 5, as good by 2, and as fair by 4. A dentist who called it much better than similar trays said, 'I'm extremely impressed. I think I've found my new impression tray. I have only praise for ease of use, comfort, and impressions and final results of crowns and bridges.'
