It is fabricated in a dental lab from a self-taken impression by a full-time technician with over 15 years of experience under the supervision of a dentist and orthodontist with over 30 years of practice; the material is BPA- and phthalate-free and listed at 1.02 mm thick (about 49% thinner than the brand's standard hard night guard, though a separate product section cites 1.2 mm laminate). Each order includes two sets of impression putty, three impression tray sizes (small, medium, large), a return shipping box with a prepaid return label, and an order information sheet, and the product carries a 6-month guarantee plus free replacement of defective units within 60 days of receipt (120 days for premium retainers) per the brand's FAQ; it holds a 4.7/5 rating across 47 reviews. Note: orders for two or more people must be placed separately.","url":"https://clearretain.com/products/premium-hard-night-guard","brand":"ClearRetain","condition":"new","product_category":"Uncategorized","material":"Clear hard laminate","weight":"4.5 oz","item_weight_unit":"oz","age_group":"adult","image_url":"https://cdn.shopify.com/s/files/1/0052/8046/4985/files/PremiumHardNightGuardUpper0.png?v=1695864850","additional_image_urls":["https://cdn.shopify.com/s/files/1/0052/8046/4985/files/PremiumHardNightGuardLower.png?v=1695864855","https://cdn.shopify.com/s/files/1/0052/8046/4985/files/PremiumHardNightGuardUpper.png?v=1695864855","https://cdn.shopify.com/s/files/1/0052/8046/4985/files/Lowerx2.jpg?v=1730247148","https://cdn.shopify.com/s/files/1/0052/8046/4985/files/Upperx2.jpg?v=1730247279"],"images":[{"id":"img-1788213718214-0","url":"https://cdn.shopify.com/s/files/1/0052/8046/4985/files/PremiumHardNightGuardUpper0.png?v=1695864850","width":1500,"height":1500,"alt_text":"Premium Hard Night Guard product image (primary)","position":1,"attributes":{"other":{"summary":"Studio-style product shot on a white background with a purple gradient 'Best Seller' badge in the top-left and soft shadows beneath the case.","observations":[{"key":"Promotional badge text","kind":"text","value":"A purple rounded rectangular badge in the top-left contains the text 'Best Seller'.","regions":[{"x":0.02,"y":0.06,"width":0.42,"height":0.2,"confidence":"high"}],"evidence_status":"direct"},{"key":"Background and lighting","kind":"feature","value":"Even white background with soft diffuse lighting and subtle shadow under the case toward the bottom-right.","regions":[],"evidence_status":"direct"},{"key":"Shot composition","kind":"feature","value":"Product is centered slightly to the right and shown from an angled top-front perspective, cropping the lower-right of the case.","regions":[],"evidence_status":"direct"}]},"colors":[{"name":"translucent clear","part":"night guard (translucent body)","regions":[{"x":0.36,"y":0.15,"width":0.52,"height":0.41,"confidence":"high"}],"subject":"product","description":"Clear translucent glossy thermoplastic allowing highlights and background to show through.","sampled_hex":"#F5DC8C","estimated_hex":"#F8F8F8"},{"name":"bright yellow","part":"case exterior","regions":[{"x":0.19,"y":0.3,"width":0.66,"height":0.5,"confidence":"high"}],"subject":"packaging","description":"Bright glossy solid yellow finish on a rounded plastic clamshell.","sampled_hex":"#F8D024","estimated_hex":"#FFD200"}],"product":{"summary":"A clear U-shaped dental night guard sits on top of a yellow rounded plastic clamshell case.
