It is fabricated in the U.S. from BPA- and phthalate-free orthodontic-grade material, and orders include a dental self-impression kit for a precise fit; over 98% of appliances fit on the first try and a 120-day guarantee applies. User reviews indicate the lower retainer is relatively easy to obtain and typically lasts about a year or more with normal wear.","url":"https://clearretain.com/products/upper-retainer-night-guard-for-heavy-grinding-copy","brand":"ClearRetain","condition":"new","product_category":"Uncategorized","material":"BPA and phthalate-free orthodontic grade material","weight":"4.5 oz","item_weight_unit":"oz","image_url":"https://cdn.shopify.com/s/files/1/0052/8046/4985/files/3_2.png?v=1776988958","additional_image_urls":["https://cdn.shopify.com/s/files/1/0052/8046/4985/files/4_1.png?v=1776988978"],"images":[{"id":"img-1788214083881-0","url":"https://cdn.shopify.com/s/files/1/0052/8046/4985/files/3_2.png?v=1776988958","width":1500,"height":1500,"alt_text":"Lower Retainer-Night Guard product image (primary)","position":1,"attributes":{"other":{"summary":"Studio-style product shot on a plain white background photographed from a slightly elevated front-right angle.","observations":[{"key":"Shot composition","kind":"feature","value":"Product is centered in the lower two-thirds of the frame with empty white space above; camera angle is slightly elevated and rotated to the right.","regions":[],"evidence_status":"direct"},{"key":"Lighting and shadows","kind":"feature","value":"Even diffuse lighting with soft shadows beneath the case and faint specular highlights on the guard.","regions":[],"evidence_status":"direct"},{"key":"Image quality","kind":"feature","value":"High-resolution, sharply focused on product with neutral white background and no visible text or props aside from the case and guard.","regions":[],"evidence_status":"direct"}]},"colors":[{"name":"clear (transparent)","part":"night guard body","regions":[{"x":0.18,"y":0.16,"width":0.66,"height":0.48,"confidence":"high"}],"subject":"product","description":"Transparent glossy thermoplastic with specular highlights and very low visible tint.","sampled_hex":"#ABC39B"},{"name":"pale mint green","part":"storage case exterior","regions":[{"x":0.2,"y":0.46,"width":0.6,"height":0.38,"confidence":"high"},{"x":0.54,"y":0.69,"width":0.2,"height":0.16,"confidence":"medium"}],"subject":"packaging","description":"Uniform pale muted green plastic with a matte to low-sheen finish.","sampled_hex":"#B3CC95","estimated_hex":"#A4D39A"}],"product":{"summary":"A clear thermoformed dental lower night guard is shown resting on top of a green rounded storage case.
