In iDental, 3D bio-replicas ensure the success of the treatments

iDental Asistencia Dental Social maintains a commitment to the evolution of technique and science within the dental sector. In its more than 100,000 m 2 of facilities spread throughout Spain, the United Kingdom and Mexico; iDental has dedicated R + D + i areas equipped with the highest technology. The 3D reproductions of body parts are a good example of the technological level of Social Dental Assistance centers. The bio-replica 3D printing system is a great help in planning the treatments of the hundreds of patients who visit iDental centers .

3D printers have revolutionized the medical sector with different applications. In Spain, today stand out its advantages in the manufacture of light prostheses such as the artificial arm of Unai Blanco, a 9-year-old boy, who with this prosthesis much more adaptable to his anatomy than the annoying orthopedic accessory that he refused to use , was able to partially regain the functionality of his limb.

At iDental they use 1: 1 scale physical reproduction of the patient’s bone anatomy to improve diagnosis and surgery planning. It allows dentists to work on a full-size model before doing it on the patient. In this way, through the information collected through a scanner, they have a physical model that will allow them to analyze the disease without disturbing the patient.

By means of bio-replicas of the different parts of the human body, an intuitive, direct study can be carried out and deepen the understanding of a case. Among its applications in maxillofacial surgery, the possibility of calculating the size and scope of tissues to be removed, the planning of grafts, the reproduction of tumors prior to surgery or the reproduction by symmetry stand out. The latter consists of the reconstruction of a damaged part of the face from its opposite symmetry.

If the patient requires the placement of a titanium mandibular chain or other prostheses for the synthesis of fractured skull bones , it is possible to apply them previously on a 3D model in order to reduce time in subsequent surgical intervention.

A real model is also very useful to increase the interaction with the patient in the explanation of the treatment, as teaching material or to adapt custom splints and prostheses before their placement. Unapproachable a priori cases can be planned to the millimeter to reduce time and complexity in surgery.

In the dental implantology area of iDental, bio-replicas that include realistic reproductions of bone and soft tissues are used to plan treatments that affect bone and gums.

In edentulous patients, iDental dentists sometimes perform a complex treatment to rehabilitate the lower jaw with implants known as lateralization of the dental nerve. This treatment requires manipulating a delicate nerve. Knowing its exact location is essential for the success of the treatment and thanks to a bio-replica of the mandible equipped with an exploratory window with simulation of the nerve, subsequent surgery can be planned.

Zygomatic implants also require a refined technique that can be projected onto a replica. These implants are anchored on the zygomatic bone, the cheek bone and involves the entire part of the patient’s posterior facial section. The iDental 3D printer also reproduces the upper jaw including the zygomatic bone in its entirety, so the work on bio-replicas is included in the iDental surgical protocols in the treatment with zygomatic implants.

iDental makes use of life-size bio-replicas to provide more information to the laboratory supplying prosthetic attachments, thus ensuring the reception of a prosthesis that perfectly fits the needs of the patient.

In the manufacture of bio-replicas, the quality of the scan shots plays a fundamental role. iDental has high-tech helical TAC scanners whose exploration yields enough data and high fidelity for export to the 3D printing system. No Gantry tilt, layer thickness 0.5-1.5mm, and no software post-reconstruction, with a file-sequenced output configuration, one for each axial tomographic slice. Some fundamental characteristics for the fidelity of the bio-replicas in relation to the original anatomical sections of the patient.

3D printing in the maxillofacial medical sector allows printing of the entire skull, from the posterior facial section to the ear canals, upper jaw, upper jaw including the entire zygomatic bone, lower jaw to the upper hole of the dental canal and maxilla inferior including condyles and apophysis. In this way, the variety of anatomical sections allows choosing the most appropriate for the study of each ailment depending on the number of affected areas.

Hundreds of patients have already benefited from iDental Social Dental Assistance with advanced oral surgery treatments previously studied and planned with 3D bio-replicates. High technology for a quality healthcare service in the dental health sector.
