All on 4 Implant Concept

The treatment of patients with highly atrophic jaws is one of the most difficult aspects of implant dentistry. Atrophy may be horizontal, vertical, or both; even if enough vertical bone is present, a lack of ridge width may prevent care with implants 4 mm in diameter or larger. Many methods, protocols, and materials have been developed over the years to resolve the challenging issues associated with the treatment of atrophic jaws. In the posterior maxilla, one early solution was to augment the sinus when inserting implants at the same time. Where the mandibular bone height is less than 12.0 mm, tissue augmentation techniques such as bone ridge expansion and bone grafts are usually required to enable conventional dental implants to be placed. Despite their widespread use, these approaches are clinically difficult and result in higher tissue and implant morbidity.

Modern oral rehabilitation strategies focused on the use of dental implants and immediate loading techniques have been shown to allow for the rapid and efficient restoration of patients with superior esthetic and masticatory properties while reducing morbidity and tissue damage. Implant assisted prosthesis care is virtually impossible in some cases of fully edentulous patients without complicated procedures such as nerve transposition and grafting in the posterior maxilla and mandible. The All-on-4 Implants is a solution for such cases. Because of the proximity of essential anatomical structures such as the mandibular canal and maxillary sinus, implant assisted prosthesis may not be possible in many cases. Many methods, procedures, and materials have been developed over the years to solve the complex problems associated with treating atrophic jaws while avoiding the proximity of critical anatomical structures, such as short implants, alveolar distraction osteogenesis, directed bone generation, intraoral and extraoral autogenous bone grafts, nerve repositioning, and so on. Such methods have been limited in their usage due to the high cost, time, and morbidity associated with them.

Distally tilted implants were proposed at the turn of the millennium, allowing for the use of denser bone in the anterior mandible for better bone anchorage, as well as the replacement of posterior teeth without extended cantilevers and without the need for bone grafting. The “all-on-four” treatment concept was created to optimize the use of usable remnant bone in atrophic jaws, allowing immediate function while avoiding regenerative procedures that increase treatment costs, patient morbidity, and complications.

All on 4 Implants Cleaning

Implanted teeth, like natural teeth, are vulnerable to bacterial damage and infections. You may have heard the expression “clean your teeth after every meal” as a child. Well, this is also one of the most basic ways to maintain good oral hygiene. Cleaning the dental implants after each meal ensures that the debris from the implants is dislodged until it sticks to the dentures and becomes a bacterial breeding ground. Cleaning dental implants can be done in a variety of ways.

  • After each meal, floss your bridge to remove any food debris that might have become trapped underneath it.
  • Use water and an antibacterial mouth rinse to rinse your mouth. Alcohol-based mouthwashes should be avoided.
  • Use an electric toothbrush to clean the dentures. Cleaning with an electric toothbrush is both easy and thorough.
  • To make sure there are no bacteria left in your mouth, clean the top of your tongue and the insides of your cheeks. Clean off the dirt that gets caught on your tongue when eating with a toothbrush.
  • Make it a routine to visit your dentist every 2 to 3 months for a professional cleaning.

Denture Material Comparison

The materials used to produce quality dentures differ from lower-quality dentures. Better quality dentures are often made with high-grade acrylics and porcelain to mimic or complement natural teeth. As a result, these dentures will serve you well for many years. The color of your gums can also influence how natural your dentures appear. High-quality dentures have unique coloring and tinting to match your skin tone and established gum tissue characteristics. Since we use an acrylic injection mold, we can guarantee that your new dentures can shrink by no more than 0.1 percent.

Conclusion

In patients who do not want to undergo regenerative treatments, which raise morbidity and care costs, the all-on-four treatment concept provides a predictable way to treat the atrophic jaw. The findings show a 99.8% survival rate after 24 months. However, existing evidence is limited due to a lack of data related to methodological consistency, insufficient follow-up, and sample attrition. After an average follow-up of two years, biological complications (e.g., peri-implantitis) are recorded in just a few patients. Due to the high prevalence of peri-implant diseases, an appropriate description of the success/survival criteria is needed.
