Página: https://glossdent.com/en/all-on-x Your assessment ## A full arch calls for a complete treatment discussion All-on-X describes an arch restoration supported by several implants; All-on-4 and All-on-6 refer to four or six supports. The number is chosen within an individual surgical and restorative plan. Before considering extractions, discuss the options for teeth that remain. Your assessment should explain the proposed prosthesis, treatment sequence and cleaning and follow-up needs. It depends on your case ## All-on-4, All-on-6 or an overdenture? It depends on your bone and on what you can maintain For people who have already lost the teeth in one arch, or are going to lose them for valid reasons, implants greatly improve daily life compared with a denture. In studies, the difference between 4 and 6 implants is small. What matters most in the long run is the prosthesis: it needs maintenance and repairs over the years. It is not a treatment for removing teeth that can still be saved. | If your assessment shows… | Usually considered… | | --- | --- | | You still have teeth that can be kept | Keep them: a systematic review cautions against extracting teeth with a good prognosis to do a full arch. | | 4 or 6 implants? | At 5 years or more, 98.1% versus 97.5% survival: no meaningful difference. The number comes from your bone and the size of the arch. | | Little bone in the back | Tilted implants at the back (the All-on-4 concept), which performed as well as straight ones. | | Very little bone in the upper jaw | Extensive grafting or zygomatic implants (anchored in the cheekbone): less time until you have teeth, and more complications. It is a technique for experienced surgeons. | | You want temporary teeth within 24 to 48 hours | It is possible if the implants are firm once placed; if not, you wait a few months. | | No teeth in the lower jaw | An overdenture on 2 implants is the standard first choice; more than 2 implants did not improve what patients reported. | | A fixed or a removable prosthesis on implants? | Both improve function compared with a denture. It is decided by the bone, the space, lip support, ease of cleaning and your preference. | | Prosthesis material | All-acrylic prostheses fracture more; zirconia might reduce mechanical complications. | General criteria from the clinical literature (sources below). They do not replace an assessment: your plan comes from the diagnosis of your own case. Is it right for me? ## Who it is usually indicated for, and what is treated first ### It is usually considered for… - People with no teeth in one arch, or with teeth that truly cannot be kept. - People who want something fixed, or more stable than a conventional denture. - People who can commit to a special daily cleaning routine and lifelong checkups. ### Confirmed or addressed first… - That your current teeth truly cannot be saved. - Smoking, uncontrolled diabetes and periodontitis. - High-dose bone medications for cancer: they rule out implants. - That the prosthesis will need adjustments and repairs over the years: this is planned from the start. What to discuss ## A plan you can understand ### Preservation and alternatives Ask why a full arch is proposed and what options exist to retain teeth. ### Prosthesis and support Clarify whether the restoration would be fixed or removable, the materials and access for cleaning. ### Stages and continuity Request a timetable that distinguishes temporary teeth, healing and the final prosthesis. The process ## How a full arch on implants is done 1. **Assessment and CT scan** And a plan with alternatives: an overdenture or a fixed prosthesis, and how many implants. 2. **Extractions, if needed** Only of the teeth that cannot be kept. 3. **Implant surgery 1 appointment** With grafts or zygomatic implants if needed. 4. **Fixed temporary prosthesis 24 to 48 hours** When the implants are firm; if not, you wait. 5. **Integration several months** The implants fuse with the bone. 6. **Final prosthesis** In the material chosen in the plan. 7. **Maintenance for life** Cleaning under the prosthesis, checkups, and the adjustments or repairs that are to be expected. Common questions ## Before you decide ### How long does an All-on-4 last? At 3 years, studies report that 99% of implants and almost all prostheses were still in place; at 5 years or more, about 98%. There is little data at 10 years or more. “Still in place” is not “problem-free”: at 10 years, only 8.6% of full-arch fixed prostheses had not had a single complication. ### What complications are common? Those of the prosthesis: chipping or fracture of the outer veneering layer (a third at 5 years and two-thirds at 10 in one review), screws that loosen or break, and bone loss around an implant. That is why maintenance is part of the treatment. ### Do I leave with teeth the same day? Often a fixed temporary prosthesis is placed within the first 48 hours, if the implants are firm. The final one is made once they integrate, months later. ### Is it better than a denture? In studies, both the fixed prosthesis and the overdenture on implants greatly improve chewing and satisfaction compared with a conventional denture. ## Clinical sources The criteria and figures on this page come from these sources.
