Red color-coding on the shank ring identifies this bur as fine grit per the ISO diamond bur color-coding standard, allowing clinicians to select the correct grit from a multi-grit diamond bur tray setup at the chairside without reading individual bur markings during the preparation or finishing sequence.\u003cbr\u003e\u003cbr\u003eRestorative dentists and prosthodontists who use FG flame diamond burs for crown preparation margin work, veneer preparations, and finishing procedures find Mydent Defend Diamond Bur #863 Fine Grit Red the correctly specified friction grip flame finishing bur for their active restorative and crown preparation workflow.\n?\nEach pack contains 10 individual FG Long Flame Fine Grit Diamond Burs at 1.6mm head diameter, providing a practical per-operatory supply for active crown preparation and finishing use across multiple patient appointments. At 1.6mm head diameter the #863-016 provides the standard flame tip width for interproximal access during crown preparation and veneer preparation, with the long flame body length delivering the extended working surface area along the lateral surface of the bur that allows smooth, continuous margin feathering strokes from the gingival margin upward along the axial wall of the preparation without the stepped transitions that shorter bur geometries produce when the preparation must be completed in multiple adjacent passes. Fine grit diamond particle size is suited for the finishing steps of crown preparation where residual roughness from coarser bur passes is smoothed to the surface quality that impression material captures accurately.\n?\nMydent Defend Diamond Bur #863 Fine Grit works through its electroplated diamond particle matrix on the long flame stainless steel mandrel body, where the fine grit diamond particles remove enamel, dentin, and ceramic material by abrasion at the points of contact between the rotating bur surface and the tooth or restoration material during active use.\u003cbr\u003e\u003cbr\u003eFine grit designation means the diamond particles are sized within the ISO fine grit range that produces lower surface roughness per cutting stroke than medium or coarse grit burs at the cost of reduced cutting speed, making fine grit the appropriate selection for finishing, margin refinement, and surface smoothing steps where cutting efficiency is secondary to surface quality at the preparation surface. Long flame geometry positions the taper of the bur body to allow the clinician to approach the gingival margin from above with the tip angling slightly toward the preparation margin, facilitating feathering and chamfer refinement at the cervical preparation area without the shank obscuring vision of the margin during the finishing stroke.\n?\nRestorative dentists completing porcelain-fused-to-metal and all-ceramic crown preparations find fine grit flame burs at the finishing stage produce the smooth axial wall and chamfer margin surfaces that accurate impression taking and precise laboratory crown fabrication require. Dental assistants managing diamond bur tray setups for crown preparation appointments find the red ring color coding allows rapid grit identification during instrument selection without removing the bur from its cassette position for marking inspection.\n?\nMydent Defend Diamond Bur, FG, Long Flame, Fine Grit, Red, 1.6mm gives dental practices a red-ring ISO-coded fine grit FG friction grip long flame diamond bur at 1.6mm for crown preparation margin finishing, interproximal reduction, chamfer refinement, and subgingival access finishing in a 10-count pack suited for active daily restorative and prosthodontic preparation workflows.\u003cbr\u003e\u003cbr\u003eFor dental offices ordering diamond bur supplies for crown preparation and finishing programs, Defend #863 Fine Grit Red delivers the geometry, grit precision, and finishing performance that consistent crown preparation margin quality requires.\u003c\/p\u003e","brand":"Mydent International (Defend)","offers":[{"title":"FG \/ Flame \/ 1.6 mm","offer_id":51368134377793,"sku":"DEF-863-016F","price":13.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/2525\/5233\/files\/129594_main.webp?v=1770258436","url":"https:\/\/carolinadental.com\/products\/defend-diamonds-flame-863-016f-10-pack","provider":"CAROLINA DENTAL SUPPLY INC","version":"1.0","type":"link"}
