Chin, mandibular angles and contour, cheekbones, paranasal region and orbit. The shape is designed from the CT and agreed before surgery.
Patient-specific geometry from CT for different facial regions. The region, volume and approach are chosen by the surgeon.
The implant volume and position are designed from the CT, keeping intraoperative adjustment to a minimum.
Paired regions are designed in a single coordinate system — the implant restores the bone contour rather than masking it.
3D visualisation of the implant and soft tissues, an anatomical model and the device itself — arguments you can show and put in the patient's hands.
Patient-specific implants are indicated when standard methods (lipofilling, osteotomies, off-the-shelf plates) do not deliver a predictable aesthetic and functional result.
Midface and lower third of the face after trauma.
Developmental anomalies of the facial skeleton.
After failed surgeries.
Volume restoration after resections.
Requiring precise volumetric correction.
When it matters that the patient sees the result before surgery.
Contouring can be addressed in different ways, from soft tissue procedures to patient-specific implants. The surgeon chooses the method and material according to the clinical situation.
| Method | Summary | Key features |
|---|---|---|
| Fillers | Soft tissue treatment, without surgery | A temporary effect requiring repeat procedures; they do not restore bone contour |
| Bone grafting | Volume restoration with the patient's own tissue | More invasive; partial graft resorption is possible |
| Medpor (porous polyethylene) | Porous implant, tissue ingrowth | Off-the-shelf shapes, adjusted intraoperatively; removal is difficult |
| Silicone | Preformed implant | A capsule forms; it does not integrate with tissue |
| PEEK (patient-specific) | High-strength, produced from the CT and 3D plan | Patient-specific geometry, radiolucency, shape approved before surgery |
This summary is general in nature; data on risks and complications can be found in the literature at the end of the page. The applicability of each method depends on the anatomy, the soft tissues and the surgical plan.
No scattered instructions in chats — your case is assigned a dedicated support engineer and a step-by-step workflow.
Send us the task and an engineer will advise on applicability and a possible solution.
3D visualisation and a model for approval — the patient sees the result in advance.
Following the protocol, an engineer builds an accurate implant model.
Revisions before manufacturing, then printing and delivery of the kit to the clinic.
A correct CT scan speeds up planning and reduces rework. Download the protocol for this speciality and include a link to the DICOM when you send it.
The construct is manufactured to the agreed plan: the physician approves the 3D fit, volume and position before manufacturing, and revisions are made at the model stage. Prior 3D planning makes the shape and fit of the device more predictable; the final result depends on the clinical situation and the course of surgery.
With a correct CT protocol and the design agreed before manufacturing, the amount of intraoperative adaptation can be reduced — the shape and fit are calculated in advance from the CT. Decisions during surgery remain with the surgeon.
A 3D model of the implant and the soft tissues is built from the CT; if required, an anatomical model and a mock-up of the implant are produced. This helps the physician discuss the planned solution with the patient. Bonabyte does not replace an in-person consultation and does not guarantee a clinical outcome.
Patient-specific PEEK is designed from the CT for the individual anatomy: the shape and position are agreed in advance, without reshaping off-the-shelf forms during surgery; PEEK is radiolucent and compatible with CT/MRI. PEEK may be preferable for patient-specific bone contouring where precise geometry, fixation to the CT plan and prior approval of the shape matter. The choice of material and method rests with the physician.
Your case is assigned a dedicated support engineer: a step-by-step route “physician → patient → CT → order”, help with the first case and with BonaPlanner onboarding — without scattered instructions in chats.
When restoring the bone contour, symmetry and stable volume to an individual plan matters, this is a different task from soft tissue techniques. The physician chooses the approach and method according to the clinical situation.
Bonabyte designs and manufactures the device according to the treating physician's plan. Medical decisions are made by the surgeon.
These publications are provided as a reference for professionals. They relate to the topic of this section and are not a guarantee of the outcome in any particular case; applicability is determined by the treating physician. The list should be reviewed and expanded by a clinical specialist.
The information on this website is intended for healthcare professionals and does not constitute medical advice, a public offer or a guarantee of clinical outcome. Bonabyte devices are custom-made medical devices designed for a specific clinical task; their applicability depends on the CT data, the anatomy, the condition of the soft tissues, the surgical access and the operative plan. The final decision on the use of a device is made by the treating physician. Contraindications exist and an individual assessment of the clinical situation is required.
