Advanced Veterinary Services

Pre-operative planning uses the individual patient’s CT-derived anatomy to analyse the surgical situation digitally before the procedure. Depending on the case, this may include anatomical and mechanical measurements, deformity analysis, osteotomy planning, implant positioning, drilling or screw trajectories, and simulation of the intended correction.

Patient-specific surgical guides are designed in CAD to fit defined anatomical surfaces of the individual patient. Depending on the procedure, they can support osteotomy positioning, drilling, K-wire placement, reduction, alignment or spinal stabilisation. Bio3Dtech offers guide solutions for applications including corrective osteotomies, spinal stabilisation, arthrodesis and transcondylar screw procedures.

Our surgical guides are 3D-printed from high-precision biocompatible resin. The guide material is suitable for steam sterilisation in an autoclave. Bio3Dtech specifies sterilisation at 121 °C / 250 °F or 134 °C / 273 °F for its guide systems. For selected product workflows, NextDent SG photopolymer is used.

Yes. The CT-derived 3D anatomy can be used to analyse the deformity and calculate the intended correction. Patient-specific osteotomy, stabilisation or reduction guides can then be designed to help transfer the approved digital plan to surgery. Where appropriate, Bio3Dtech can also provide a customised titanium plate and matching screws as part of the solution.

Yes. Bio3Dtech can provide CT-based deformity analysis, pre-operative planning, patient-specific osteotomy guides and, where required, a customised plate for femoral deformity correction. The individual anatomical and mechanical angles can be analysed before the final correction is planned with the surgeon.

Yes. Bio3Dtech offers a broad range of anatomical 3D models. They can be used for pre-operative visualisation and planning, education and training, practising fracture-treatment techniques and, depending on the model, pre-operative plate contouring. The Bio3Dtech shop currently includes individual bones, coloured bone models and movable joint models.

Yes. In addition to standard anatomical models, patient-specific models can be produced from CT/DICOM data. These can reproduce the patient’s anatomy for pre-operative planning, visualisation, implant preparation or comparison with a planned corrected anatomy.

Standard anatomical models are generally produced from PLA and are not steam-autoclavable. Bio3Dtech states that these models can be disinfected with suitable alcohol-based products, but steam sterilisation can damage the material. Surgical guides are produced separately from biocompatible, steam-sterilisable resin.

Patient-specific implants are designed around the individual CT-derived anatomy and the surgical plan. Bio3Dtech manufactures customised implants using medical-grade titanium alloy and high-precision 3D printing. Depending on the solution, locking screws can be incorporated into the implant concept and supplied with the case.

For current patient-specific implant products described in the Bio3Dtech shop, final implants are manufactured by 3D printing from Ti6Al4V Grade 23 ELI titanium alloy. This material combines high strength, corrosion resistance and biocompatibility for implant applications.

Yes. Bio3Dtech offers patient-specific planning and drill-guide solutions for spinal stabilisation. These can also be combined with the Bio3Dtech spinal stabilisation set, which includes screws in several diameters, rods, connectors, a torque-controlled screwdriver and the required instrumentation. The set can be purchased or rented.

A Patellar Groove Replacement (PGR) is a specialised partial knee replacement used in veterinary orthopaedics for selected cases of patellar luxation and severe pathology of the femoral trochlear groove. Bio3Dtech designs patient-specific PGR implants from CT data, taking the individual anatomy and biomechanical requirements of the patient into account. The final implant is manufactured in titanium alloy, with a polished groove surface designed to provide an appropriate tracking surface for the patella.

Many patients referred to Bio3Dtech for a patient-specific PGR are complex patellar luxation cases in which conventional surgical options have already been exhausted, have failed previously, or are no longer considered suitable by the treating veterinary surgeon. The decision to use a PGR and the final treatment strategy remain the responsibility of the veterinary surgeon.

No. A patient-specific PGR is a standalone implant solution and does not routinely require a femoral deformity correction. In selected patients, however, patellar luxation may coexist with a clinically relevant femoral deformity. If correction is part of the surgeon’s treatment plan, Bio3Dtech can combine the patient-specific PGR with deformity analysis, corrective planning, surgical guides and, where required, an additional customised implant.

Depending on the case, the workflow can include CT segmentation and anatomical analysis, CAD-based PGR design, patient-specific surgical guides, anatomical models and polymer prototypes for verification, followed by final manufacture of the patient-specific titanium PGR. Additional deformity-correction planning is included only where clinically required.

Bio3Dtech’s portfolio also includes customised solutions for bone deformity correction, joint reconstruction and other complex orthopaedic applications. The exact implant concept is developed case by case according to the patient’s anatomy and the surgical objective.

An ITAP is an Intraosseous Transcutaneous Amputation Prosthesis: a patient-specific implant concept that creates a transcutaneous connection between the skeletal system and an external prosthetic component. Bio3Dtech offers ITAP solutions for dogs and cats, designed around the individual patient’s anatomy.

As with other patient-specific Bio3Dtech implants, planning starts from CT/DICOM data. The anatomy is segmented and reconstructed digitally, and the implant is designed in professional CAD software in collaboration with the treating veterinary surgeon. The final implant geometry, interface and fixation are developed according to the individual case.

Yes. Hydroxyapatite (HAp) coating can be incorporated into selected patient-specific implant solutions where it forms part of the agreed implant specification. Its use is assessed case by case within the overall implant and surgical planning strategy.

No. Bio3Dtech solutions are modular and defined according to the individual procedure. A case may involve pre-operative planning, surgical guides, an anatomical model, a patient-specific implant, or a combination of these elements. The required scope is agreed with the treating surgeon.

Bio3Dtech’s interactive 3D dog skeleton is intended to organise clinical examples by anatomical region. By selecting a highlighted area, veterinary professionals can explore examples of pre-operative planning, surgical guides, patient-specific implants and other case-specific solutions.
