Intraoral Scanning

After tooth preparation and soft-tissue management, an intraoral scanner (Helios 500) captures accurate digital impressions of the prepared tooth and opposing arches

CAD Design and 3D Printing

The STL file is sent to the lab, where it is processed for CAD modeling and optional 3D printing (SprintRay Pro 2) to verify fit and adaptation.

Zirconia Crown Milling

Using CAD software (e.g., exocad), the crown is designed and milled from a zirconia disk, ensuring precise margins, proper anatomy, and accurate fit.

Internal Surface Treatment

After milling and sintering, the crown’s internal surface receives a glass-ceramic coating (Biomic LiSi Connect) enabling acid etching; glazing and staining optimize final esthetics.

Implant and Provisional Restoration

Tooth 11 was extracted, and direct implantation was decided. After four months, a healing abutment was placed, and a digital scan was performed using a scan body. The provisional restoration was adapted and bonded to adjacent teeth.

Zirconia Abutment and Preparation

A zirconia abutment (Aidite 3D Pro Zir, Qinhuangdao, China) was placed over the implant. At this point, all old restorations were removed, and caries were cleaned to prepare for the restoration of the adjacent teeth.

PMMA Provisional and Restoration

A new PMMA provisional was prepared on the zirconia abutment. The mesial gingival part of tooth 21 was restored with composite, following the cervical convexity of the 11, to minimize the black triangle between the central incisors as much as possible.

Zirconia Crown

The zirconia crown (Aidite 3D Pro Zir) was cemented on the abutment, and you can see the perfect match with adjacent teeth. Note the closure of the black triangle between the 11 and 21.

Surgical Plan

Upon examination, we noticed she had a lateral gummy smile, which we informed her would benefit from a bilateral surgical treatment. In the picture, you can see the surgical plan.

Post-Surgical Situation

This image shows the situation after the surgery. it is a part of a carefully planned approach that involved both surgical and prosthetic procedures to deliver a satisfying final result.

BOPT Preparation and Scanning

Once the soft tissues had perfectly healed, we performed BOPT (Biologically Oriented Preparation Technique) preparations, and an intra-oral scan was taken.

Final Restoration

Here’s the final result with monolithic 3D Pro Zir (AIDITE), slightly layered at the incisal third. Minor adjustments were made to the premolars with direct composite to enhance aesthetics and reduce dark buccal corridors.
