The main difference is the number of implants: four in All-on-4 and six in All-on-6. All-on-6 distributes the forces better when there is enough bone, while All-on-4 makes it possible to treat cases with less available bone and, often, to avoid grafts.<\/strong><\/p>\n<h2>What they are and what they share<\/h2>\n<p>Both techniques are designed for people who have lost all the teeth of an arch, or are about to lose them, and want a fixed solution that does not have to be taken in and out. In both, the full prosthesis is anchored on implants, and in many cases a provisional prosthesis can be fitted the very same day thanks to <a href=\"https:\/\/www.implantarex.com\/carga-inmediata\/\">immediate loading<\/a>. Both avoid the uncomfortable removable denture and restore a stable bite and a natural smile.<\/p>\n<h2>Key differences<\/h2>\n<ul>\n<li><strong>Number of implants:<\/strong> four in All-on-4 versus six in All-on-6.<\/li>\n<li><strong>Force distribution:<\/strong> with six implants the chewing load is spread more evenly, which can be an advantage in arches with high chewing demand.<\/li>\n<li><strong>Bone required:<\/strong> All-on-4 is designed precisely to make the most of the available bone, placing the rear implants at an angle, which makes it possible to avoid grafts in many cases.<\/li>\n<\/ul>\n<h2>Advantages of each technique<\/h2>\n<p>All-on-4 stands out for its versatility: by needing less bone, it opens the door to a fixed solution for people who would otherwise need longer preliminary treatments. All-on-6 offers, when there is enough bone, extra support that some specialists prefer for full arches with a strong bite. Neither is better than the other in absolute terms: the best technique is the one that fits your case.<\/p>\n<h2>The role of available bone<\/h2>\n<p>The quantity and quality of the bone are the factors that weigh most in the choice. When bone is scarce, All-on-4 is usually the natural option. If the specialist considers that the base needs reinforcing, a <a href=\"https:\/\/www.implantarex.com\/regeneracion-osea-dental-zaragoza\/\">bone regeneration<\/a> can be considered before the treatment. That is why the first step is always a study with imaging tests that shows precisely how much bone you have.<\/p>\n<h2>What the process is like<\/h2>\n<p>The treatment starts with a complete study and digital planning. On the day of surgery the implants are placed and, where possible, a fixed provisional prosthesis with immediate loading. After a few months of integration with the bone, the final prosthesis is fitted. If you want to understand one of these solutions better, you can read our article on <a href=\"https:\/\/www.implantarex.com\/blog\/implante-dental-all-on-four\/\">All-on-4<\/a>.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Which one is more expensive?<\/h3>\n<p>All-on-6 usually costs somewhat more because it involves two more implants, but the indication is set by the clinical case, not just the price.<\/p>\n<h3>Will I have teeth the same day?<\/h3>\n<p>In many cases yes, with a provisional immediate-loading prosthesis while waiting for the final one. The specialist will confirm whether your case allows it.<\/p>\n<h3>Which one lasts longer?<\/h3>\n<p>Both are very stable, long-lasting solutions. What matters is not the number of implants itself, but good planning and proper maintenance.<\/p>\n<h3>Is the prosthesis removed for cleaning?<\/h3>\n<p>The prosthesis is fixed and you do not take it out yourself. It does need careful daily hygiene and check-ups, where it is sometimes removed in the clinic for a thorough cleaning.<\/p>\n<p>Want to know which technique fits your case best?
