Restore a full arch of fixed teeth with just four implants—designed for patients with bone loss, digitally planned by SmileLink-verified surgeons for stable, natural results.
A complete and transparent patient guide
All on 4 is a full arch dental implant solution designed for patients who have lost most or all teeth and want fixed teeth that feel stable and natural. The concept is to support a complete arch bridge using four strategically placed implants, often with angled posterior implants to maximize available bone support.
This guide explains what All on 4 is who it is suitable for how the process works and what patients should understand before choosing this type of full arch restoration.
All on 4 is a full arch restoration where four dental implants are placed in the jaw to support a fixed bridge. The implants act as artificial tooth roots and the bridge replaces a full row of teeth, restoring appearance and everyday function.
All on 4 is designed to provide fixed teeth without the movement or discomfort many patients associate with removable dentures.
All on 4 may be a good option for patients who
• Have lost most or all teeth in one or both jaws
• Want fixed teeth rather than removable dentures
• Have reduced bone volume and want a solution that may avoid extensive grafting
• Want a stable bite and improved chewing confidence
• Are looking for a predictable plan with clear steps and long term goals
All on 4 is often considered by patients who want a full smile restoration but have less bone than ideal for higher implant counts.
All on 4 may not be the first choice if a patient has
• Untreated gum disease or active infection
• Medical conditions that affect healing and implant integration
• Very severe bone loss that requires major reconstruction
• Poor oral hygiene habits or low willingness to maintain daily care
In these cases additional preparation or alternative treatment plans may be more appropriate.
All on 4 uses a strategic implant layout to support a full arch bridge. The posterior implants are often placed at an angle to increase stability and use available bone more effectively, especially in the back of the jaw where bone loss is common.
This approach can offer strong support for fixed teeth while reducing the need for bone grafting in selected cases.
Modern All on 4 treatment relies on 3D diagnostics and digital planning. The goal is to position implants based on bone anatomy, bite function, and the final bridge design.
Digital planning helps improve precision, predictability, and long term comfort by ensuring the restoration is built around proper function, not only aesthetics.
Although each case is individualized, All on 4 treatment typically includes
Consultation and full diagnostics
Digital planning and bite assessment
Implant placement surgery
Temporary fixed teeth when clinically appropriate
Final bridge after healing and stability are confirmed
The process is structured to restore function safely while aiming for a natural looking result.
Implants are typically made of biocompatible titanium. The final bridge may be made from materials such as zirconia or reinforced ceramic based systems, selected according to bite forces, aesthetics, and long term durability goals.
Material selection should be explained clearly so patients understand what they are receiving and why it fits their case.
All on 4 is a surgical and restorative treatment that requires careful planning. Important factors include
• Bone quality and implant stability
• Accurate positioning and prosthetic design
• Bite alignment and force distribution
• Daily hygiene access around the bridge
With proper diagnostics, an experienced team, and good patient maintenance, All on 4 can provide stable and long lasting results.
Depending on the clinical situation, alternatives may include
• All on 6 full arch implants
• Implant supported dentures
• Bone grafting with delayed implant placement
• Conventional removable dentures
Each option has different advantages, limitations, and maintenance needs.
All on 4 is designed as a long term solution. Long term success depends on
• Proper implant integration and bridge design
• Daily cleaning and hygiene habits
• Regular professional checkups and maintenance visits
• Managing bite forces and avoiding damaging habits
Patients should receive clear guidance on cleaning tools and follow up schedules.
Patients researching All on 4 typically focus on
• Stability and confidence when eating and speaking
• Reduced need for extensive bone grafting
• Clear planning and realistic expectations
• Durable materials and long term function
• A natural looking smile with fixed teeth
A good treatment plan addresses both function and long term maintenance, not only appearance.
All on 4 is a full arch restoration designed to rebuild stability, function, and confidence for patients who want fixed teeth and may have reduced bone. The best outcomes come from accurate diagnostics, professional planning, quality materials, and a strong maintenance routine.
Understanding the steps and choosing the right clinical plan helps patients make informed decisions and feel confident about their long term result.
In many cases a fixed provisional bridge is fitted the same or next day, so you leave with secure teeth while healing.
A full-arch bridge that doesn’t move—comfortable eating, clear speech, and a smile designed to look naturally yours.
Tilted back implants make the most of limited bone, so bone grafting is often not required—fewer surgeries, faster care.
