The use of 3D additive manufacturing technology in autogenous dental transplantation

Abstract

Background In medicine and dentistry, 3D technology allows the virtual planning and printing of surgical replicas of anatomical structures that can facilitate certain transplant procedures. In dentistry, 3D technology is useful in autogenous tooth transplantation. Case presentation We present a clinical case of an ectopic mandibular second premolar, describing the preoperative planning with dental replicas and the autotransplantation surgery. 3D prints of the surgical replica of the tooth to be transplanted was made using an Objet30 Prime® Printer, PolyJet. Clinical controls performed at 3, 6 and 12 months indicated the satisfactory evolution of the transplanted tooth. Conclusion 3D additive manufacturing technology allows the preparation of a new recipient socket with the aid of a surgical replica of the tooth to be transplanted, thus minimizing handling and extraoral time.

Instant in-situ Tissue Repair by Biodegradable PLA/Gelatin Nanofibrous Membrane Using a 3D Printed Handheld Electrospinning Device

“…The shape and housing device manufactured, using 3D printing, conformed to the ergonomic design, and it was convenient for one-handed handheld operation. 3D printing new medical devices can be used in several departments, such as anesthesia, orthopedics, dental, and neurosurgery (Cahuana-Bartra et al, 2020 ; Faldini et al, 2020 ; Lan et al, 2020 ).…”

Three Dimensional Printing – From A Pediatric Dentist’s Perspective

“…Furthermore, wherever possible, the donor tooth's extraoral handling time should be kept to a minimum, as it has a negative impact on the tooth's viability. 10,11 To minimise damage to the donor tooth, helical CT/cone beam computed tomography is used in tandem with computer-aided rapid prototyping, which the printing of dental replicas for use as guides during surgery, thereby minimising extra-oral time and limiting possible damage to the donor tooth's periodontal tissue. All of this promotes the formation of a new recipient socket, so eliminating dangers to the donor tooth and, more broadly, aiding in the standardisation of the technique.…”

Infraocclusion level and root resorption of the primary molar in second premolar agenesis: A retrospective cross-sectional study in the Portuguese population

“…53 In cases with palatal clefts involving complex decisions, like osseous grafts or the need to preserve crucial anatomic structures, CBCT may be required. Combining low mAs (16) and kVp (70) with a small voxel size (180 μm) enables the association of a low effective dose with high image quality. 54 More recently, the possibility of using magnetic resonance imaging (MRI) as a feasible tool for orthodontic treatment planning without radiation exposure has been described, by transforming the acquired data into lateral cephalograms, allowing reliable measurements, similar to those applied in orthodontics routine or related disciplines, such as orthognathic surgery, despite the need for specific post-processing software and an experienced user.…”

“…Despite not being focused on M2P agenesis, a study by Cahuana-Bartra et al revealed that patients with hypodontia showed satisfaction with resinbonded bridges over a 7-year observation period, with an 88% success. 70 Regarding treatment options, data from 42 studies published in the years 1980-2015 presented a mean survival of 95.3%, 94.4%, 89.6%, and 60.2% for implants, autotransplants, retained primary teeth, and conventional prostheses, respectively. 64 Meanwhile, the mean satisfaction rates for the type of treatment, i.e., for implants, conventional prostheses, autotransplants, and orthodontic space closure, 93.4%, 76.6%, 72.0%, and 65.5%, respectively.…”
