Dental 3D printing technology has developed rapidly in recent years. With its advantages of high precision, customization and rapid prototyping, it is changing the traditional dental diagnosis and treatment model, covering multiple fields such as restoration, orthodontics, implantation, and surgery. The following are the main application scenarios and technical details of dental 3D printing:
1. Restoration field: denture and restoration production
- Crown/bridge:
Through oral scanning or CBCT data, 3D print resin or ceramic temporary crowns, or make casting models of metal (cobalt-chromium alloy, titanium) crowns and bridges, and finally restore with porcelain or all-zirconium.
Advantages: high precision (error <50μm), reducing the distortion of traditional mold turning.
- Removable denture:
Directly print resin base and artificial teeth (such as light-curing resin), shortening the traditional wax model and boxing process.
Materials: biocompatible resin (such as Dental SG), nylon, etc.
2. Orthodontic treatment: invisible braces and auxiliary tools
- Invisible braces (such as Invisalign, Angelalign):
3D print the patient's dentition model and produce transparent braces through hot pressing film technology.
Technology: DLP (digital light processing) or SLA (stereolithography) printing, layer thickness 25-100μm.
- Personalized brackets/lingual braces:
Directly print metal or ceramic brackets to achieve precise bonding position.
3. Dental implants: surgical guides and personalized abutments
- Implant guides:
Based on CBCT and oral scan data, 3D printed resin guides accurately guide the implant angle and depth to avoid nerve or maxillary sinus damage.
Advantages: Improve surgical safety, especially for complex bone conditions (such as insufficient bone volume).
- Personalized abutment/temporary crown:
Print titanium alloy or zirconia abutments to match the patient's gum morphology.
4.Surgery and maxillofacial restoration
- Jaw model:
Print the patient's jaw anatomical structure (such as preoperative planning for fracture reduction), the material is mostly photosensitive resin or plaster.
5.Dental education and patient communication
- Teaching models:
Printing models of dental caries, periodontal disease and other pathological conditions for medical student training.
