All-on-4 Dental Implants
A Permanent Solution for Complete Tooth Loss
All-on-4 is a revolutionary dental procedure that replaces an entire arch of teeth with just four strategically placed implants. Unlike traditional dentures, All-on-4 gives you fixed, permanent teeth that look, feel, and function like natural teeth.
What is All-on-4?
Understanding the procedure that's transformed millions of smiles
All-on-4 is an advanced dental implant technique developed by Dr. Paulo Maló that uses four titanium implants to support a full arch of replacement teeth. The name comes from the concept: 'all teeth on four implants.'
What makes All-on-4 revolutionary is the strategic placement of the implants. The two back implants are placed at a 45-degree angle, which maximizes contact with available bone and provides exceptional stability—even in patients who have experienced bone loss.
Unlike traditional implant methods that may require 6-8 implants per arch and bone grafting procedures, All-on-4 typically requires no bone grafts and can be completed in a single day. You walk in with failing teeth and walk out with a beautiful, functional smile.
The prosthetic teeth attached to All-on-4 implants are fixed in place—they don't come out for cleaning like dentures. You brush them like natural teeth and care for them with normal oral hygiene practices.
Key Facts About All-on-4
Problems All-on-4 Solves
If you're experiencing any of these issues, All-on-4 may be the solution you've been looking for
Complete or Near-Complete Tooth Loss
Whether due to decay, trauma, or gum disease, losing most or all of your teeth affects every aspect of daily life—from eating to speaking to smiling with confidence.
Loose or Uncomfortable Dentures
Traditional dentures can slip, cause sore spots, and require messy adhesives. Many denture wearers avoid social situations and restrict their diet due to denture problems.
Severe Tooth Decay Beyond Repair
When multiple teeth are severely decayed or infected, extraction and full arch replacement is often the best path to restore oral health and prevent further complications.
Advanced Bone Loss in the Jaw
Traditional implants require adequate bone. All-on-4's angled implant placement maximizes existing bone, often eliminating the need for bone grafting procedures.
Chronic Gum Disease (Periodontitis)
Advanced periodontal disease destroys the bone and tissue supporting your teeth. All-on-4 removes diseased teeth and provides a fresh start with healthy, maintainable prosthetics.
Ongoing Dental Pain and Infections
Living with constant tooth pain and recurring infections takes a toll on your quality of life. All-on-4 eliminates problematic teeth and replaces them with a pain-free solution.
Why Timing Matters
Delaying treatment for severe dental problems leads to progressive, irreversible consequences
Progressive Bone Loss
Begins immediately, accelerates over yearsWithout tooth roots to stimulate the jawbone, bone resorption begins immediately after tooth loss. You lose up to 25% of bone width in the first year alone, and this continues throughout life.
Facial Structure Changes
Noticeable within 1-2 yearsAs bone deteriorates, your face loses its structural support. This causes the lower third of your face to collapse inward, creating a prematurely aged appearance with sunken cheeks and thinning lips.
Nutritional Deficiencies
Develops gradually, compounds over timeDifficulty chewing leads to avoiding healthy foods like raw vegetables, fruits, and proteins. Studies show people with tooth loss have significantly lower intake of essential nutrients.
Speech Difficulties
Immediate and ongoingMissing teeth and ill-fitting dentures affect pronunciation of certain sounds. This can impact professional communication and social confidence.
Systemic Health Risks
Risk increases with durationChronic oral infections are linked to heart disease, diabetes complications, and respiratory infections. Untreated dental disease affects your whole body.
The Longer You Wait, The More Complex Treatment Becomes
Early intervention means more bone to work with, simpler procedures, and better long-term outcomes. Patients who act quickly often avoid bone grafting and achieve more predictable results.

The All-on-4 Procedure
What to expect from consultation to your new smile
Comprehensive Evaluation
1-2 hoursYour journey begins with a thorough examination including 3D CT scans to assess bone density and structure. We'll review your medical history, discuss your goals, and create a detailed treatment plan.
Treatment Planning & Design
1 week before surgeryUsing advanced digital planning software, we map the precise position of each implant for optimal support. You'll see a preview of your new smile and approve the design before proceeding.
Surgery Day
2-4 hours per archUnder sedation or general anesthesia, remaining teeth are extracted if needed, and four implants are placed in each arch. A temporary prosthetic is attached the same day—you leave with teeth.
Healing Period
3-6 monthsOver the next 3-6 months, the implants fuse with your jawbone through a process called osseointegration. You'll wear comfortable temporary teeth during this time and follow a soft food diet initially.
Final Prosthetic
2-3 appointmentsOnce fully healed, we take new impressions and create your permanent prosthetic teeth. These are custom-crafted from high-quality materials for natural appearance and long-term durability.
