A new era in the world of implantation: Prama implants from Sweden & Martina

Implantology is an area where new concepts and technologies regarding dental implants are constantly being developed. Despite the fact that dental implants began their development back in the 70s, there are still many aspects that can be improved. In particular, this relates to the development of new designs and methods for implant placement. This is exactly what the Italian doctors decided to do. In collaboration with Sweden & Martina, a top manufacturer of implant manufacturers, they developed new Prama dental implants, which significantly improved implant parameters and changed the concept of implantation.

It used to be that the most important component in dental implants is bone. Since it is bone tissue that holds the implant and creates a strong connection, which contributes to the engraftment of the implant. Based on this parameter, the principles of implantation were built, operations to build bone tissue were prescribed, and appropriate structures were created.

As it turned out later, not only bone tissue but the gum itself is important. It protects the implant from the penetration of microbes along the crown and to the bone where the implant is located.

Implantation development

The very first dental implants were flat and had screw fixation. Such implants were called plate form implants. To install them, it was required to make long furrows in the bone. Part of the implant went through the gum and protruded above it, thereby creating support for the prosthesis or crown. The main disadvantage of these dental implants was that the implant could break during operation, which required its replacement. And it is much more difficult to remove such implants than to install.
Then appeared cylindrical implants with a polished neck at the gums, which were called soft tissue. Thanks to this design, the implant already had some contact with the gum, which favorably influenced its engraftment. However, there was no strong connection at the gingival level, since only the epithelium appeared there, which did not have such properties as bone tissue. And this was fraught with the fact that various microbes could penetrate the bone.

Soft tissue implants also had low aesthetic performance, especially when installed on the front teeth. Over time, gum shrinkage occurred, due to which part of the implant was exposed and was visible to others.

This technology was further improved, as a result of which implants were created that were placed at the bone level, from which they were called bone level implants. They made it possible to improve aesthetics by hiding implant joints under the gum. With this design, the implants were in contact only with the bone tissue and did not reach the gums, therefore, additional details had to be screwed onto such implants to support the crowns, which was their weak point. These details also did not have a strong connection with the gum, due to which various microbes could penetrate under the gum and reach the bone itself, which would lead to its destruction around the implant.

New generation of implant

At the moment, a third generation of implant development has appeared, which eliminates the aforementioned drawback. These are intramucosal implants.

The procedure for their installation is similar to that for bone level implants, but the intramucosal dental implants have a special polished part for contact with the gums. Unlike other polished neck implants, Sweden & Martina's Prama implants are convergent, which allows for greater gum growth. In addition, their surface has micro-grooves with a depth of 60 microns and is additionally processed so that it makes the tissue cells (fibroblasts) more firmly attach to this surface with grooves. Fibroblasts are responsible for the production of collagen fibers, which not only create a strong connection but also multiply. And this, in turn, means that the gums will fit more tightly to the implant and bone tissue, without letting germs and infections inside.

Advantage of intramucosal implants

implants pramaDue to its design and capabilities, intramucosal implants practically negate part of bone augmentations or reduce them to the category of less invasive (atraumatic) ones.

Due to this, the patient who selects this type of implant receives a number of advantages:

  • The healing time of the implant in the bone is reduced from 6 months to 3-4. Therefore, the installation of dental implants will be performed in a shorter period;
  • Less traumatic and invasive installation. In most cases, there is no need to perform bone grafting and make numerous incisions, which makes the installation of implants more comfortable;
  • Excellent aesthetic appearance. Due to the stability of the gum and its larger volume, the aesthetic appearance of the jaw will be much better;
  • Safety. By installing such an implant, the gum is firmly soldered to the surface (UTM) of the neck, and everything that happens inside the gum no longer affects the implant.

Contraindications:

  • Lack of bone tissue;
  • Immunodeficiency and changes in the thyroid gland;
  • Uncontrolled diabetes mellitus with an indicator of more than 12 mmol/l;
  • Oncological diseases.
