Patient evaluation

Every successful All-on-4 treatment begins with a detailed and personalised patient evaluation. This stage is much more than just “taking X-rays.” It’s a comprehensive diagnostic process that allows the dentist to create a treatment plan tailored to each individual’s anatomy, health, and goals.

• Digital X-rays & CBCT scans – provide detailed 3D images of the jawbone and sinus anatomy.
• Bone density analysis – determines whether bone grafting is necessary (often avoided with All-on-4).
• Oral health review – assessment of gums, remaining teeth, and bite.
• Medical history & lifestyle – conditions like diabetes or smoking habits are considered in planning.

This stage gives patients clarity and confidence. By the end of the evaluation, most patients already know whether they are candidates for All-on-4 and what to expect during the subsequent phases of treatment.

Implant placement surgery

Once planning is complete, the procedure moves into the surgical stage — the placement of the four implants. For many patients, this is the part they worry about most. Still, in reality, it is usually a comfortable process performed under local anaesthesia, often combined with sedation to help patients relax.

The procedure usually takes only a few hours per arch. Patients often report that they feel pressure during the placement but not pain. Afterwards, some swelling and mild discomfort are normal, but these symptoms are usually manageable with prescribed medication and subside within a few days.

For patients who have had teeth extracted during the same appointment, the implants are often placed immediately into the extraction sites, further reducing treatment time. This combination of efficiency and precision is what makes the surgical phase of All-on-4 such a breakthrough in modern implantology.

Immediate loading – same-day teeth

Perhaps the most exciting aspect of the All-on-4 method is the concept of immediate loading, also known as “Teeth in a Day.” Traditionally, implants required months of healing before any teeth could be attached. With All-on-4, patients leave the practice on the same day of surgery with a fixed temporary bridge securely attached to their implants.

Benefits for patients:

• Walk out of the clinic with a new set of fixed teeth.
• Immediate ability to smile and speak with confidence.
• No long waiting period with removable dentures.

Patients often describe this stage as life-changing. Instead of waiting months with removable dentures, they wake up from surgery already enjoying the benefits of fixed teeth.

Provisional prosthesis

The temporary bridge, known as the provisional prosthesis, plays a critical role in the overall success of the treatment. While it is not as durable as the final prosthesis, it is carefully designed to:

• Protect the implants during the healing phase
• Restore function so patients can chew and speak normally
• Provide a natural-looking smile during recovery

Dentists typically recommend a soft food diet during this period — foods like mashed potatoes, scrambled eggs, fish, smoothies, and pasta are ideal. Hard, crunchy, or sticky foods should be avoided, as they can put unnecessary stress on the new implants.

The provisional phase also gives patients a chance to “test drive” their new teeth. They can provide feedback on comfort, bite alignment, and aesthetics, which helps the dental team fine-tune the design of the final prosthesis.

Healing and osseointegration

The healing phase is when the fundamental biology of implant dentistry takes place. Over the course of several months, the titanium implants undergo a process called osseointegration, during which they fuse directly with the jawbone. This creates a stable and permanent foundation for the final prosthesis.

The healing period typically lasts 3 to 6 months, though it can vary depending on the patient’s health, bone density, and adherence to post-operative care instructions. During this time, patients may experience minor gum tenderness or changes in bite as the tissues adapt, but these are temporary and closely monitored during follow-up visits.

Key recovery guidelines include:

• Maintaining excellent oral hygiene with a soft-bristled toothbrush and antibacterial rinses
• Avoiding smoking and alcohol (both delay healing and increase the risk of implant failure)
• Sticking to a soft-food diet for at least the first few weeks
• Attending scheduled check-ups so the dentist can monitor progress

By the end of this stage, most patients have become fully adapted to their provisional prosthesis and are ready to proceed to the next and final step: the placement of their permanent teeth.

Final prosthesis placement

After healing, the temporary bridge is replaced with a permanent custom-made prosthesis.

Types of final prosthesis:

• Acrylic over a titanium frame – durable and cost-effective.
• Porcelain or zirconia bridge – highly aesthetic, long-lasting.

Ongoing follow-up care

Regular maintenance is crucial for ensuring long-term success.
