All-on-4® Dental Implants in Bangkok: Immediate Fixed Teeth for Expats at HeySmile Dental Clinic
If you’re an expat in Bangkok experiencing full jaw tooth loss (edentulous jaw) or struggling with uncomfortable traditional full dentures and bone resorption in the posterior area, the All-on-4® (or ProArch) treatment concept offers a revolutionary, minimally invasive solution. At HeySmile Dental Clinic, we specialize in providing immediate fixed full-arch restoration, allowing you to regain a beautiful, functional smile rapidly.
What is All-on-4® / ProArch Dental Implants?
The All-on-4® / ProArch concept is designed to provide you with a provisional fixed full-arch prosthesis on the same day as your surgery. This means you can walk out with new, functional temporary fixed teeth shortly after your dental implant placement!
- How it Works: This innovative technique strategically places four dental implants into your jawbone – two straight implants at the front and two implants tilted at a 45º angle in the posterior area.
- Maximizing Bone: By tilting the posterior implants, we maximize the use of your existing front jawbone, often avoiding the need for complex bone grafting procedures in the back.
- Immediate Function: This is followed by a custom-designed implant-retained hybrid denture or full prosthesis securely attached to the implant posts.
The All-on-4® / ProArch treatment concept can be successfully applied to both the upper and lower jaws, offering a stable and reliable solution for total tooth replacement. While typically involving four implants, our implantologists may recommend more based on your unique bone and oral conditions for optimal long-term success.

Key Benefits of All-on-4® Implants at HeySmile Dental Clinic
Choosing All-on-4® at HeySmile Dental Clinic offers distinct advantages compared to other full jaw implant options:
- Immediate Teeth: You receive new, fixed teeth almost immediately after your dental implant surgery, ensuring a smooth transition and instant aesthetic and functional improvement.
- Shortened Treatment Duration: The overall treatment time is often significantly reduced compared to traditional full mouth implant procedures.
- Avoids Bone Grafts (in selected cases): The tilted implant placement technique maximizes existing bone, frequently eliminating the need for extensive bone grafting in the posterior areas.
- Fixed & Stable Solution: Enjoy the comfort and confidence of permanent teeth that won’t slip or move.
- Improved Quality of Life: Eat, speak, and smile with renewed confidence and comfort.
Your All-on-4® Dental Implants Procedure at HeySmile Dental Clinic
At HeySmile Dental Clinic, we follow a meticulous multi-step process, combining cutting-edge technology with the expertise of our implant specialists for your All-on-4® treatment.
Step 1
FREE Diagnosis & Personalized Treatment Planning
Your journey begins with a FREE comprehensive consultation at HeySmile Dental Clinic. Our dental specialists will:
- Thoroughly evaluate your oral health and bone condition to determine your suitability for immediate function full-arch implant treatment.
- Address any existing infections in gums or jawbone, which must be treated first. If significant bone loss is present, alternative options or a modified approach may be discussed.
- Perform digital panoramic X-rays and a CT scan. These images are crucial for our oral surgeons to pre-plan the optimal angle and depth for your implant posts.
- Digital surgical template guides may also be created upon request for enhanced precision.
Step 2
Preliminary Checks & Preparations for Comfort
Before your All-on-4® surgery, any necessary preliminary dental treatments will be completed.
- The actual implant post surgery can be performed under local anesthesia as an outpatient procedure in our day clinic.
- For patients desiring a higher level of comfort, we offer options for moderate sedation or even general anesthesia (additional health checks and preparation timings will be required for these options).
- If you opt for sedation and will be returning home the same day, we recommend having someone accompany you after your visit.
Step 3
Precise Dental Implant Surgery
On the day of your surgery, our implant oral surgeon will provide any specific instructions based on your chosen sedation option.
- The placement of your dental implant posts is typically completed within 1 to 3 hours by our highly experienced implant oral surgeons.
HeySmile’s team of implantologists comprises top-tier specialists ensuring the highest standards of care.
Step 4
Immediate Fixed Hybrid Dentures / Provisional Prosthesis
Shortly after surgery, our prosthodontist will take an impression of your implants to begin building your provisional fixed hybrid dentures.
- The All-on-4® / ProArch concept is specifically designed to maximize the opportunity for immediate function. Your HeySmile dentist will often be able to place a temporary restoration on, or very shortly after, the day of surgery.
- Based on your actual bone condition and the initial surgical placement, your implant dentist will inform you whether your prosthesis is ready for immediate or delayed loading.
