Fixed Implant-Supported Teeth

The fixed implant supported bridge or teeth option relies on implants to secure a full complement of replacement teeth to the jawbone.This approach allows the teeth to be fixed to the implants and can only be removed by the dentist. These teeth feel, look, and function like natural teeth and eliminate all the problems associated with regular removable dentures. They are designed to allow easy cleaning and maintenance. They typically requires a larger number of implants (anywhere from 4 to 8 implants). The different options of fixed implant supported teeth are

Fixed Hybrid Prosthesis

A full set of teeth which are fixed and completely supported by dental implants. This design utilizes 4 to 8 dental implants depending on patient’s jaw anatomy and span of the bite.

Fixed Implant-Supported Bridge

A conventional bridge supported by 6 to 8 dental implants. This option is possible when the bone has normal architecture and patient desires closest look and feel of natural teeth.


All-on-4 concept is a fully fixed set of teeth on 4 dental implants. Variations of this design may be all-on-5 or all-on-6 resembling the design of a fixed hybrid prosthesis. This is a minimal design for a fixed set of teeth and may be appropriate for those with less available bone.


‘Same-Day-Teeth’ or ‘Teeth-in-a-Day’ refer to a treatment approach where a patient can have remaining teeth extracted with immediate placement of dental implants and delivery of an implant-supported fixed temporary prosthesis. Patient literally leaves the office with a new set of teeth on the same day.

Fixed-Hybrid Teeth

For patients who don’t want dentures that come out, there is the fixed option. This approach allows the prosthesis to be fixed to the implants and can only be removed by the dentist. They are designed to allow easy cleaning and maintenance.

  • All-on-4: With this options, a fixed prosthesis is supported by four implants. This can be used in patients with significant bone loss in the back of their jaws. Implants are positioned in a way that does not require bone grafting.
  • Five-Six Implants:This is ideal for a fixed-hybrid prosthesis. This is an overdenture that has a metal sub-structure and is fixated to the implants. The prosthesis can be removed only by your dentist, if necessary. This eliminates denture extensions or flanges and feels more natural.
  • Eight Implants:This is indicated for a fixed bridge. This prosthesis is made of porcelain or other ceramics and is supported by implants via screws or cement.
  • Advantages of fixed prosthesis:

  • More closely resembles the feeling of natural teeth.
  • Because it is completely supported by implants, no denture flanges are necessary therefore making it more comfortable.
  • Extremely stable so any type of food can be chewed easily.
  • Easily cleaned.
  • Disadvantages of fixed prosthesis:

  • More costly than a removable prosthesis.

Fixed Implant-Supported Bridge

Complete loss of teeth and use of simple dentures is a crippling disease impacting the livelihood and quality of life. Patients can not eat well and stop smiling. With loss of teeth, the jaw bone also deteriorates rapidly. As the jaw bone melts away and gum shrinks your muscles migrate, or pull back, from their natural position. Your lips lose the support, and wrinkles increase dramatically as your facial structures & bite collapse. The results are inability or difficulty to eat, loss of confidence, embarrassment, and accelerated feeling and appearance of aging.

You don’t have to live your life with such a crippling problem. Millions of people now days have benefited from dental implants supporting new teeth that they can use to chew better, smile more, and improve their overall quality of life. Lifetime Dental Implants at 3D Dental implant clinic, Kolkata india is ready to help you.

ALL-ON-4 Treatment

The ‘All-on-4′ is a dental implant treatment option for those with completely missing teeth. The implants can be placed either in an immediate fashion on the same day as extractions (Teeth-in-a-Day) or in delayed fashion once the extractions sites have healed (Delayed implant placement). The ‘All-on-4′ refers to placement of the entire prosthesis (i.e. teeth) on 4 dental implants. The prosthesis can be either removable or fixed.

The ‘All-on-4′ treatment is a great solution for patients who have lost significant bone in the back of their jaw and where bone grafting is not desired. The dental Implants are positioned in a way that does not require bone grafting while providing great support for the prosthesis. The ‘All-on-4′ technique can be done in both upper and lower jaws.

Patients with teeth that require Extraction:

A common scenario is a patient who needs all of their teeth extracted due to severe decay or gum disease. Here is how it works:

  • Teeth are extracted.
  • Four immediate dental implants are placed on the same day. This is known as immediate implants.
  • An immediate full denture is then placed and supported by the four implants on the same day. This is known as immediate restoration.
  • The implants are allowed to heal for 2-3 months before fabrication of the final implant-supported prosthesis.
  • The implant-supported prosthesis is fixed to the implants with retaining screws and can not be removed by the patient.

‘ALL-ON-5′ OR ‘ALL-ON-6′:

Four implants are the minimum number of implants for this approach. However, it may be recommended to place 5 or 6 dental implants for additional support. More implants may be recommended for those with a large biting surface or strong chewing habits. The additional implants provide greater stability, strength, and support for the prosthesis. If you love eating harder food, the additional implants will be of great benefit to you



Teeth-in-a-Day refers to the process where a patient can have necessary extractions done, dental implants placed and have an implant-supported prosthesis, all in the same day. It combines immediate implants and immediate restorations principles, so that a patient can come to the office in the morning, have all necessary surgery and prosthetic work completed, and leave home in the afternoon with fixed new teeth in place.

To achieve success, a number of factors must be considered:

  • Health of the extraction sites
  • ntegrity of the surrounding bone
  • Location of implants
  • Type of prosthesis
  • Patient bite and forces of chewing

Immediate implant placement shortens the overall treatment time and consolidates your procedures into one. We offer Teeth-in-a-Day treatments but only to patients who meet strict criteria. Violation of such criteria significantly increases complications and failure rate.


Advertised widely by chain implant centers, the Teeth-in-a-Day concept has become largely a marketing fad. Teeth-in-A-Day, while promising and successful in selected group of patients, lacks sufficiency in its science, knowledge, literature, research, and expertise that is required to achieve predictable results. The approach may be successful, but only in very few candidates with no infection around their teeth, have great amount of bone, and all conditions are ideal. If conditions were this perfect, why would they need to have their teeth extracted to begin with? Many commercial “implant centers” do a hard sell to fit a patient into a treatment plan. Healthy natural teeth end up being extracted in order to place multiple implants and connect them with an immediate prosthesis on the same day! There are some evidence-based studies on this approach, but there are too many variables not yet thoroughly understood. Use of this approach in poor candidates results in high rates of failure and implant loss.

Many experts advise patients to be cautious of such hard advertisements and made promises that are often impossible to deliver.
