Case Study: Digital DSD Smile Design + Anterior All-Ceramic Aesthetic Restoration
Published On: March 26, 2026
Case Background
The patient presented with misaligned anterior teeth, tooth defects, and an uncoordinated smile curve, seeking to improve facial aesthetics and occlusal function while preserving natural teeth. After a comprehensive oral examination and facial aesthetic evaluation, a digital DSD smile design combined with all-ceramic restoration plan was adopted to achieve precise aesthetic reconstruction and functional recovery.
Restoration Process
- Multi-dimensional Data Acquisition: Intraoral 3D scanning was used to capture dentition and gingival morphology data, while static and dynamic facial smile photos were taken to establish a digital correlation between the facial midline, lip line, and dentition, providing an accurate basis for aesthetic design.
- DSD Virtual Aesthetic Design: The post-restoration dentition shape, length, and alignment were simulated in professional software, matching the patient’s facial proportions and lip shape. The smile arc and tooth proportions were adjusted, and the final effect was previewed in real time. The final plan was confirmed with the patient to meet personalized needs.
- Minimally Invasive Tooth Preparation: Following minimally invasive principles, teeth were prepared precisely according to the design plan, removing only necessary tooth tissue to reserve appropriate space for the all-ceramic restoration, maximizing the preservation of natural tooth health and vitality.
- All-Ceramic Restoration Fabrication & Placement: The all-ceramic restoration was fabricated using CAD/CAM digital milling technology, featuring natural translucent color and high consistency with the design plan. During try-in, occlusion and marginal adaptation were finely adjusted, followed by final bonding to complete the dual restoration of aesthetics and function.
Restoration Outcome
After restoration, the anterior teeth were neatly aligned, with a smooth and natural smile curve that perfectly coordinated with facial proportions. The tooth color was uniform and translucent, and the patient’s smile aesthetics and occlusal function were significantly improved. The restoration was comfortable to wear with no foreign body sensation, achieving the ideal “data-driven, personalized” repair effect.
