Case report

The case study conducted at the Faculty of Dentistry at Damascus University from August 1, 2020, to January 2, 2022, focused on utilizing digital technology to improve the cosmetic appearance of a 23-year-old female patient’s smile. The patient expressed dissatisfaction with the gap between her upper incisors and sought a non-invasive solution. Upon examination, orthodontic treatment was initially recommended but the patient opted for a more immediate and aesthetic solution. It was proposed to create four porcelain veneers using e.max^® CAD/CAM technology to close the gap and enhance the overall appearance of her smile. The Medit i700 scanner was used to capture a detailed 3D model of the patient’s upper jaw through an orofacial scan. This innovative approach allowed for the precise design of the veneers, ensuring a custom fit and natural look. The methodology employed in this case study involved a systematic approach to utilizing digital technology to address the cosmetic concerns of the patient. Various stages were followed to ensure a comprehensive assessment, treatment planning, and execution of the treatment. Initially, extraoral and intraoral photographs were taken to assess the patient’s condition and plan the treatment. Subsequently, intraoral scans of the upper and lower jaws were performed using the Medit i700 scanner to capture detailed 3D models. Digital smile design was carried out to visualize the desired outcome and plan the treatment accordingly. Tooth preparation was then performed, followed by another intraoral scan to ensure accuracy and precision. The color of the veneers was digitally selected using the software’s color selection feature to achieve an accurate color match. The porcelain veneers were then cemented to the teeth using a bonding protocol, ensuring proper alignment and fit. Throughout the treatment process, attention was paid to detail and accuracy, with regular checks and tests conducted to ensure the success of the treatment. Pre- and post-treatment photographs were taken to document the results and showcase the transformation achieved through digital technology. Overall, the method employed in this case study emphasizes the importance of thorough assessment, precise planning, and detailed execution when utilizing digital technology in cosmetic dentistry. By following a systematic approach and incorporating innovative digital tools, personalized and effective solutions can be provided to address patients’ aesthetic concerns. The digital transformation of the treatment plan not only met the patient’s cosmetic goals but also highlighted the advancements in digital dentistry. The study demonstrated the potential of digital technology in creating personalized and effective solutions for aesthetic dental concerns.

The following stages were involved in the study:

• 1.

  Various extraoral and intraoral photographs were taken in different positions (Figure 1), including frontal views with and without a smile, lateral view of the facial profile, and intraoral views with retractors. These images helped in assessing the patient’s condition.

• 2.

  Before starting the treatment, an intraoral scan of both the upper and lower jaw was performed in a lateral occlusal position (Figure 2) using the Medit i700 device.

• 3.

  Digital smile design (Figure 3) was carried out to plan the desired outcome.

• 4.

  Tooth preparation began by using an appropriate bur sequence, with the finishing line placed above the gingival level.

• 5.

  After the tooth preparation was completed, an intraoral scan was performed again. The color of the veneers was chosen digitally using a color selection feature in the software (Figure 4), ensuring accurate color matching for each tooth area.

• 6.

  The porcelain veneers were then cemented to the teeth after thorough testing and ensuring no issues. Adjacent teeth were isolated, and the bonding process followed the usual protocol for porcelain veneers.

Treating the veneer involves using 10% hydrofluoric acid to etch the inner surface for 20 seconds, followed by washing with water. Silane is then applied for a minute, followed by a layer of bond and cement, specifically a light-cured resin cement. Treating the abutments involves applying 37% phosphorous acid to the entire labial surface of the teeth for 30 seconds, followed by washing with water. A bonding material is then applied before carefully placing the veneers on the teeth, ensuring proper alignment. After light curing for two seconds, any excess material is removed before allowing sufficient time for curing. Each surface is cured for 40 seconds. Finally, it is recommended to take pre- and post-treatment photographs, both intraoral and extraoral, to document the results (Figure 5).
