All-on-6 vs All-on-4 Dental Implants

Improving your smile with All-on-4 or All-on-6 dental implants can transform your self-confidence, promote better oral health, and have a positive impact on your overall well-being. The dental implant procedure is a tooth restoration technique where a complete upper or lower arch of replacement teeth is permanently placed into your mouth, supported by four or six titanium posts surgically embedded into your jawbone.

For either or both arches in your mouth, dentists recommend All-on-4 or All-on-6 implants for patients who have lost most of their natural teeth through decay, damage, or gum disease.

So which is better for you, All-on-4 or All-on-6? Your dentist will work with you to develop a personalized treatment plan to meet your specific needs and goals for your dental implant procedure. The number of implants—or posts—to be surgically embedded into your jawbone depends on several key factors, including your oral health, jawbone structure and density, and overall anatomy:

  1. The upper jaw (called the maxilla) can sometimes require more posts because of softer bone density and the need for greater support to securely anchor your replacement teeth.
  2. The lower jaw (called the mandible) generally has denser bone, which can sometimes allow for fewer posts while still providing stability and proper function for your prosthetic teeth.
  3. The arch shape of each jaw determines post placement and distribution.

First Step: Initial Consultation

During an initial consultation, your dentist will determine the number of posts you need for each arch. Your dentist will conduct a comprehensive examination that will include X-rays and other imaging scans to assess your overall oral health and the density of your jawbone structure.

For the All-on-4 or All-on-6 dental implants process to be successful, bone density, bone volume, and gum health help your dentist decide on the approach that is best for you. Adequate bone density and volume will help your implants remain stable for everyday functions like chewing and speaking. If you have insufficient bone volume, you may require bone grafting to build up your jawbone and create a more stable foundation for your implants.

Similarly, healthy gums are essential for forming a protective seal around your implant posts, which will reduce your risk of infection and other complications. Gum health and bone health are also linked because severe gum disease can cause bone loss and necessitate bone grafting.

Second Step: Surgery

Dental implant surgery requires two to four hours to complete, depending on the number of posts to be implanted and any preparatory procedures your dentist will need to complete. Surgery typically includes the following steps:

  1. Extraction of your existing, damaged teeth will make room in your mouth for the full upper and lower arches of replacement teeth.
  2. Additional preparatory procedures can include removal of damaged gum tissue and infected bone.
  3. Titanium posts are surgically implanted into your jawbone to function like your natural tooth roots. The four or six posts per arch serve as anchors for your new replacement teeth to be permanently attached to your jaw.
  4. Bone grafting, if needed, will be completed prior to your dentist placing your full-mouth implants.

Your dentist will provide you with post-operative care instructions and medications to manage pain and promote smooth recovery.

Third Step: Placement and Recovery

After surgery, you will have temporary acrylic teeth in your mouth for about six months, possibly longer, depending on the time needed for your gums and jawbone to fully heal. Your dentist will then place your customized All-on-4 or All-on-6 implants onto your dental arches.

Your final dental implants will be built around a frame made from titanium or another durable metal or metal alloy. Your arches will consist of either an acrylic denture or replacement teeth made from composite materials. An upgrade option is dental implants made with porcelain for better durability than acrylic and a more natural appearance.

Full recovery can span several months, but once your mouth is fully healed, you will have limited disruption to your everyday life and minimal food restrictions. With proper oral hygiene and regular dental check-ups, your All-on-4 or All-on-6 dental implants can last at least 20, if not 40 years.
