The 3M ESPE Stainless Steel Crown Primary Molar Crown-D is a dental product designed for the restoration of primary molars, specifically the first molars (1st molars). These crowns are intended to provide long-term coverage for primary molar teeth, particularly the first molars, serving as a restorative solution in cases where these teeth require protection and functional restoration. They are meticulously designed to replicate the natural anatomy of primary molars, coming in various sizes to accommodate different tooth dimensions and featuring a lifelike height, contour, and occlusal surface, closely mimicking the natural tooth structure. Pre-crimped at the cervical margin, these crowns offer good retention and a secure "snap" fit, ensuring they stay securely in place during normal dental function. The smooth stainless steel alloy surface promotes patient comfort and helps maintain gingival health while harmonizing with the patient's occlusion for a more natural feel. These crowns are indicated for a range of dental scenarios, including replacing amalgam restorations in primary molars with extensive Class II cavities that extend beyond the anatomic line angles, addressing extensive caries damage affecting multiple surfaces of the tooth, managing cases with decalcification and a high risk of recurrent caries, providing space maintenance, restoring primary molars after pulp therapy or endodontic procedures, and offering a solution for developmental defects like amelogenesis imperfecta, dentinogenesis imperfecta, or hypocalcified teeth. They can serve as an interim measure in these cases to reduce tooth sensitivity and enable effective oral hygiene.
