Cutting Guide
Cutting guides are essential for enhancing accuracy and reducing surgical duration in procedures such as genioplasty, Lefort osteotomy, lower jaw angle shaving, mandibular border shaving, and similar surgeries. These guides incorporate pathways for incisions and screw placements based on specific characteristics, enabling surgeons to confidently perform bone segment cuts. Additionally, in chin surgeries, the screw placements on the guides are designed so that the same holes can be used for both bone fixation and plate placement.
Cutting guides are also used for implanting prostheses that require bone sectioning. In these cases, the cutting path on the guide is designed to ensure that the prosthesis surface perfectly contacts the remaining bone surface during implantation. This guarantees a smooth fit between the bone and the prosthesis, leaving no gaps.
Advantages of using cutting guides
What Is a Maxillofacial Surgical Guide?
A maxillofacial surgical guide, also known as a cutting guide, is a patient-specific surgical instrument designed and manufactured before surgery. It precisely defines the planned bone-cutting path, screw placement points, and intended jaw repositioning during the procedure.
In maxillofacial procedures such as orthognathic surgery, the surgeon must perform osteotomies and reposition the jaws with a high degree of accuracy. Even a small deviation from the planned surgical pathway may affect the final outcome. A patient-specific surgical guide helps minimize such deviations by transferring the digital surgical plan directly to the operating room.
Why Are Maxillofacial Surgical Guides Important?
In conventional surgical workflows, the location and orientation of bone cuts may depend more heavily on intraoperative assessment and the surgeon’s experience. Although surgical expertise remains essential, digital surgical guides provide an additional level of precision and predictability.
With a digitally designed surgical guide:
The exact osteotomy pathway is simulated before surgery.
The surgeon can perform the planned cuts without relying solely on intraoperative estimation.
Surgical time may be reduced.
The risk of positioning and cutting errors can be minimized.
Surgical outcomes become more predictable.
How Are Cutting Guides Manufactured at Farin Roshaan Teb?
Farin Roshaan Teb designs and manufactures patient-specific cutting guides through a fully digital workflow. The process includes the following stages:
Step 1: Scanning and Imaging
An intraoral scan and CBCT imaging of the patient’s maxillofacial anatomy are obtained. These datasets provide the anatomical foundation for digital planning and guide design.
Step 2: Digital Surgical Planning
The imaging and scan data are imported into specialized digital surgical planning software. At this stage, the Farin Roshaan team works in collaboration with the surgeon to determine the precise location, angle, and depth of the planned osteotomies.
Step 3: Patient-Specific Guide Design
Based on the approved surgical plan, a patient-specific cutting guide is digitally designed. The guide is tailored to fit the individual anatomy of the patient’s jaw, allowing the planned osteotomy to be transferred accurately to the surgical field.
Step 4: Three-Dimensional Printing
The surgical guide is manufactured using high-precision 3D-printing technology and biocompatible materials suitable for the intended clinical application.
Step 5: Quality Control and Delivery
Before delivery to the surgeon, the guide undergoes quality-control procedures to verify dimensional accuracy, anatomical fit, and compliance with the required sterilization protocol.
Applications of Farin Roshaan Teb Cutting Guides in Maxillofacial Surgery
Orthognathic Surgery
Patient-specific cutting guides can be used in a range of orthognathic procedures, including:
Le Fort osteotomies for repositioning the maxilla
Bilateral Sagittal Split Osteotomy (BSSO) for mandibular repositioning
Genioplasty for correction and repositioning of the chin
More broadly, cutting guides may also be used in procedures involving Le Fort osteotomies, mandibular contouring or shaving, fixation planning, and complex bimaxillary movements.
In these procedures, the cutting guide defines the planned osteotomy pathway so that the surgeon can reproduce the preoperative digital plan with greater precision.
Implant and Prosthetic Reconstruction Surgery
In reconstructive procedures involving patient-specific prostheses or implants, surgical guides can help determine the exact location of bone resection and implant placement. This allows the prosthesis to achieve the intended contact with the remaining bone and helps reproduce the digitally planned reconstruction as accurately as possible.
Complex Maxillofacial Reconstruction
In patients with defects caused by trauma, tumor resection, or congenital deformities, patient-specific cutting guides can play an important role in complex reconstructive procedures.
They can help the surgical team accurately reproduce the planned bone resections and facilitate the placement of patient-specific implants, grafts, or other reconstructive components according to the preoperative digital plan.

Opinions of users of this service
For about a year now, I have been collaborating with this company and utilizing their services in the field of surgical guide manufacturing, particularly for patients with complex anatomy or movements. The use of 3D analysis and surgical predictions, orthogonal splints, surgical cutting guides for procedures like mandibuloplasty, and custom plates for complex movements have been invaluable.
The Farinroshaan company provides a comprehensive solution for maxillofacial surgeries. They offer a full range of services, including the fabrication of custom prosthetics, various devices, and surgical splints using intraoral scanning technology. They also create jaw molds and a navigation system that is particularly useful for complex tumors in the temporomandibular joint area.
Fortunately, Farinroshaan has the capability to produce patient-specific maxillofacial prosthetics using 3D titanium printing technology. This technique allows for the manufacture of highly precise and robust prosthetics and implants tailored to the specific requirements of the maxillofacial surgical field. With this technology, we can create highly accurate orthognathic surgical guides, custom plates, and facial aesthetic implants.
One of the excellent, knowledge-based, and active companies is the respected Farinroshaan Teb Company. I have had the privilege of working with this company and its highly scientific and academic team.
In orthognathic patients, the complete design and fabrication of splints was carried out in a very short time frame with excellent quality, and the surgical outcome was very good. The total cost incurred was also reasonable. Furthermore, our patients were completely satisfied.
The achievements of the Farinroshaan Teb Company have greatly impressed me. Their use of specialized materials, highly advanced and robust scientific and practical technologies, minimizes the surgeon's work in the operating room, reduces errors to near zero, and ultimately eliminates the need for surgery, whether for patients who have undergone trauma and lost parts of their limbs, or those who require radical surgical procedures, or those suffering from other conditions. The materials and technologies offered by Farinroshaan are fascinating, scientific, and practical, and I highly recommend them to my colleagues.
