Abstract
BackgroundThree-dimensional (3D) printing technology is used widely in dentistry for applications including implant surgery, oral and maxillofacial surgery, orthognathic surgery, endodontics and prosthodontics. Using a 3D-printed template makes performing the repair procedure faster and more convenient. The aesthetic restoration of anterior teeth can recover facial beauty, enhance speaking and chewing functions and improve the quality of life of the patient.Case presentationThis article describes two kinds of clinical cases including fractured teeth and dental caries. In both, a 3D-printed template was used for direct resin composite restoration of maxillary central incisors. A 3D-printed template was built using the following 3-step process: data acquisition was conducted via intra-oral scanning, virtual modeling was performed using an imaging process, and manufacturing was performed using a 3D printer. Aesthetically restoring the maxillary incisors with the assistance of the 3D-printed template achieved the anticipated results, and the patients were very satisfied with the effect.ConclusionsThe direct resin composite restoration of maxillary central incisors using a 3D-printed template represents a rapid, convenient, aesthetic and functional option for treating maxillary central incisors. A 3D-printed template is therefore an acceptable and reliable alternative to traditional direct composite restoration of maxillary central incisors including fractured teeth and dental caries.

The anterior teeth play an important role in facial beauty, and fully recovering a fractured anterior tooth requires restoration of the color, dental anatomy, and translucency of the tooth in addition to the curvature of the smile line and harmony with the other teeth in the arc [1]
Weinlander et al [17] introduced a new method for aesthetically evaluating the peri-implant mucogingival complex in which they used a collection of standardized oral photographs and computer-assisted measurements
Summary
Three-dimensional (3D) printing technology is used widely in dentistry for applications including implant surgery, oral and maxillofacial surgery, orthognathic surgery, endodontics and prosthodontics. The aesthetic restoration of anterior teeth can recover facial beauty, enhance speaking and chewing functions and improve the quality of life of the patient. A 3D-printed template was used for direct resin composite restoration of maxillary central incisors. Restoring the maxillary incisors with the assistance of the 3D-printed template achieved the anticipated results, and the patients were very satisfied with the effect. The restored maxillary central incisors must be well adapted, aesthetic, functional, and accepted by the patient. To the best of our knowledge, no previous report has described the use of 3D printing technology for the aesthetic restoration of maxillary central incisors. We hypothesized that it would be possible to use 3D printing
