A fixed full-arch restoration on 4 or 6 implants (All-on-4 / All-on-6) is the ideal solution for patients without teeth or with severely damaged dentition. Discover the stages, advantages, durability, and estimated costs at Mr Dent Clinic, Chișinău.
When do we need a complete smile solution?
When teeth are missing or affected by severe periodontal disease, every daily activity becomes difficult: chewing, speaking, even smiling. Traditional removable dentures only mask the problem — they don’t offer stability, and the jawbones continue to resorb. Many patients feel embarrassed or afraid that the denture might move while eating or talking. Modern All-on-4 and All-on-6 techniques restore a fixed, aesthetic, functional full-arch — sometimes even on the same day.
What is the All-on-4 / All-on-6 system?
All-on-4 and All-on-6 are implantology concepts that replace the entire dental arch using only 4 or 6 implants onto which a highly resistant and aesthetic bridge is fixed.
- All-on-4 – 4 optimally positioned implants where bone is sufficient
- All-on-6 – 6 implants for additional support and enhanced long-term stability
The choice depends on:
- bone volume and quality
- degree of bone resorption
- muscular force and patient habits
- general medical condition
Treatment steps
The process begins with a detailed consultation, 3D radiograph, and digital planning to position the implants with maximum precision.
If remaining teeth are hopeless, they are extracted in the same visit.
Implants are placed strategically, especially the posterior ones, at an angle that allows using the existing bone — often without bone grafting.
In most cases, the patient receives a fixed temporary bridge the same day — which is why the system is also known as “Teeth in a day”.
After 3–6 months, once the implants are fully integrated, the final prosthesis is made from premium, highly durable, aesthetic materials.
What are the advantages over removable dentures?
• Fixed teeth that never move
• Ability to bite and chew naturally
• Normal speech and no social embarrassment
• Beautiful smile and rejuvenated facial expression
• Preservation of bone and facial contour
• Fast results — sometimes in just one day
Who is the ideal candidate?
• patients without teeth on an arch
• patients with advanced periodontitis and hopeless teeth
• denture wearers unhappy with stability
• people who want a fast and long-lasting transformation
Before treatment, general health, bone availability, habits such as smoking or bruxism, and systemic conditions are evaluated.
How durable is the treatment?
With proper oral hygiene and regular visits, All-on-4 / All-on-6 implants can last 20+ years or even a lifetime. The final prosthesis can be adjusted or replaced after many years, while the implants remain the stable foundation. At Mr Dent Clinic, we use modern maintenance protocols, including HELBO laser therapy, essential for preventing peri-implantitis.
Are there limitations?
In some situations, patients may need:
• gum treatment before implant placement
• reducing or quitting smoking
• a night guard if they grind their teeth (bruxism)
The implantologist explains every detail clearly so the patient can make an informed decision.
