Practical experience of Dr. Miskolci Sándor when using the Bioplant BC system of BIONIKA

In some situations, the oro-vestibular diameter of the neutered jaw bone is insufficient for the usage of conventional 4-4.3 mm or even 3.3 to 3.5 mm thick implants. If the patient’s general condition, lack of consent, or local characteristics of the bone tissue do not allow an artificial increase in the vertical diameter of the alveolar process (lateral onlay plastics, spinal splitting, expansion osteomal use) may be a justification for using needle implants with thin diameter (2.3 to 2.8 mm) , which can be found in the product range of more manufacturers on the implantology market.

The applicational illustration of the BIONIKA BIOPLANT BC needle implant.

Bioplant bicortical (oral and vestibular) – supported screw implants with a cranial diameter of 2.3 mm or 2.8 mm manufactured by Bionika Medline Medical Technology have been used for six years during our clinical practice, in the case of a limited bone supply or oro- vestibular diameter if there is no possibility for broadening the spine edge due to some reasons. During the prosthetic usage of these implants, we always strive to splint or integrate with each other or with other implants, which can be done by means of molded bridge frameworks or piered meso structures.

It is known that the optimal implant artificial stub connection is within the implant body. In the case of this anchoring, the approximately 3 mm or below the diameter cervical thickness of the implant has the risk of fracture. The external hexagonal splicing required for positioning or connecting during surgery is therefore a compromise and at the same time- unlike other similar products, it has the possibility of variability. The hexagon-based 2 mm height artificial stub, for which different artificial stubs can be fixed with a through-bolt, continues after the widened, shoulder shaped implant neck with an intra- or super mucosal position depending on the insertion:

  • individually millable cyclinder
  • truncated cone
  • reverse truncated cone
  • ball head retention element

It is possible to model the crown which fits to the surface or the meso structure frame , whether it is screwed or glued fixations. In addition, it is also possible to fasten a longer hexagonal diameter through-bolt to the place of the mounting screw ( even glue), thus, making it single-phase, we are able to polish and adjust our extended artificial stub implant to the clinical situation. In addition to its prosthetic variety, the product has a great advantage that it is available in extreme lengths of up to 22 to 28 mm.

In the case of patients whose status enables the utilization of extreme length implants, before that a 3D CT recording should be created, and after carefully planning the surgery, for the pre-drilling and core drilling of the implant nest , the intensified external and internal cooling of the rotating devices are required in the process. The healing of peri-implant soft tissue is sub- or transgingival depending on the thickness of the mucoperiosteum. It is also possible to have immediate, early or late prosthetic load, we prefer the latter.

Shared mezostructure (pier), on the artificial stubs of 13, 23 only with dental support, implants with intermediate elements, support and anchoring with soluble screw fixation. Overdenture with 3 preci-horix anchorings
