Technical Specifications of BTI implants.

Versatility

BTI offers a complete range of products that adapt to many clinical situations thanks to a wide variety of titanium implants of several diameters and lengths, specially designed to be surgically implanted in the maxillary or mandibular bone.

The system also includes prosthetic elements to be coupled to the implants, and auxiliary elements for surgical and prosthetic procedures. This versatility facilitates the planning of the surgical procedures and reduces the appearance of unforeseen events during the same.

The Apex

Ápice

The BTI implant has an apex with exceptional advance/drive capacity and a small apical surface. These features prevent compressions at this level facilitating directional control and its placement in very narrow crest bones.

In anatomically compromised situations, it allows the implant to advance slightly beyond the drilling and therefore avoids undesired risks in the surgery.

Ápice

  • Less apical surface – Less compression.
  • Larger osseointegration surface – Better capacity for bone integration.

BTI Surface

BTI implants have a specific multi-scale surface treatment for its bioactivation with PRGF®-Endoret®, overall favouring the deposition of high biological quality bone.

Design

The surface of BTI implants is multi-scale, with domains that range from tens of microns to a few nanometres. This design is primordial for the interaction with proteins, platelets and cells that, for their part, have different sizes and are sensitive to topographical stimuli at the micro and nanometric ranges.

The micro and nanotopography of the BTI surface is fundamental for the adsorption and organisation of the proteins, platelet adhesion and activation and the osteoblastic anchorage and differentiation. These processes are in turn primordial for a correct osseointegration

Composition

The individualised treatment processes for surface treatment and surface cleaning of BTI implants allow easy wetting and increase the interaction area with the biological tissue

This hydrophilic surface finish allows the activation through contact of the clotting process around the implant, unlike what happens with hydrophobic surfaces, where interaction with the surface is blocked by other majority proteins in the serum with scarce regenerative potential.

Bioactivation

The micro and nanotopography of BTI implants guarantees the retention of the provisional matrix on the surface, acting as a cell-anchorage mesh and as an emitter/receiver of the cell signals present in PRGF®-Endoret®

The formation of many anchorage points of the fibrin on the surface of BTI implants prevents the provisional matrix from detaching from the surface during the retraction processes or due to the contractile forces exerted by the osteoblastic cells adhered to it by means of their cytoplasmatic extensions.

Cellular Affinity

The topography of BTI implants has spaces of specific dimensions for the cells in charge of bone reconstruction, the osteoblasts. These cells take care of secreting the new extracellular matrix around the implant and of the final osseointegration.

Osteoblasts are known to be sensitive to micro and nanometric topographical modifications. In addition, the surface chemistry of BTI implants causes a viability of these types of cells that allows their correct adhesion, proliferation and differentiation, with the resulting improvement over time and the quality of the peri-implant bone regeneration.

The surface of the implant in the areas that are sensitive to exposure is designed to avoid bacterial colonisation, settle the soft tissues and, in supra-crestal positions, encourage vertical growth.

Osseointegration

The biological function of the surface of BTI implants es continuously evaluated by means of in vivo models of osseointegration and clinical follow-ups.

The surface of BTI implants allows growth of the bone through contact as well as distance osteogenesis. The physical/chemical properties of the surface are optimal for the development of the provisional matrix and its progressive replacement by the mature extracellular matrix.

Conexiones

La gama de implantes BTI está compuesta de dos conexiones: Interna® y Externa®, y diversas dimensiones de implantes en función del sustrato óseo que tengamos. De tal forma, que dicha versatilidad nos permite disponer de soluciones para cualquier problema quirúrgico-protésico de un modo muy sencillo.

Interna®

Interna

La conexión interna® tetralobulada destaca por la ausencia de aristas, que evita los puntos de fatiga. Esta geometría permite una buena distribución de cargas: axiales, laterales y de torsión, disminuyendo el riesgo de la deformación plástica durante la inserción y/o des-inserción del implante y facilitando la inserción de los componentes prostodóncicos.

Otra característica peculiar es que las dimensiones de dicha conexión son siempre las mismas, con independencia de las medidas de la plataforma.

Externa®

Externa

La conexión Externa® es un hexágono que tiene unas medidas de lado y de alto diferentes según la plataforma, con lo que están en concordancia con el requerimiento biomecánico de cada una de las mismas.

Comparativa de resistencia a la plasticidad en ambas conexiones.

Sobrepasando los 150 N/cm, el hexágono de la conexión Externa® se deteriora, en cambio para obtener una deformación plástica en la conexión Interna® de BTI, el par debe de ser mayor a 320 N/cm.

Transportador

Transportador con marcas de profundidad y con la reproducción de la conexión en el mismo, para el control de su posicionamiento.
