An 8-year-old female patient presented at our clinic complaining of pain due to food impaction in the upper left maxillary primary molar area. A medical history was taken, followed by a clinical and radiographic examination which revealed deep dentinal caries on the tooth in question tooth without any interradicular lesion ( and ). Furthermore, on the other quadrant, the complementary molar had been previously extracted as a result of pathologic bone resorption accompanied by corresponding external root resorption due to caries (). Likewise, due to patient's age and the extensive, multisurface restoration needed on the upper left maxillary primary molar, the treatment plan suggested a crown for that tooth. Moreover, patient's parents refused the SSC treatment option due to aesthetic reasons, while they request to avoid the extraction of the tooth due to negative experience from the extraction of the upper right maxillary primary molar. Topical infiltrative anesthesia was administered (2% lidocaine with 1:100,000 adrenaline), the tooth was isolated with a rubber dam, and the caries were removed with a high-speed handpiece and a carbide bur (no. 330). Selective decay removal was performed with low-speed round burs until the remaining dentin was rigid and free of decay, after the decay removal, the gingival wall was 1.0 mm under the cementoenamel junction. For this reason, a proximal box elevation was performed so that the margin in the gingival wall was at the gingival level (). The resin used for core buildup was Tetric Evoceream (Ivoclar Vivadent, Schaan, Liechtenstein). The tooth was then prepared with the diamond bur round end taper no. 8881-314-014 for an axial reduction of 0.8–1.0 mm, followed by a chamfer margin circumferentially and occlusal reduction of 1.0–1.5 mm with a round wheel no. 909—(Κomet, Brasseler, Lemgo, Germany) according to the recommended preparation guidelines of the manufacture of the hybrid ceramic block (). To allow a more effective scan with the relative isolation of the treatment field, Optragate (Ivoclar, Vivadent, Liechtenstein) was applied to ensure the lips and cheeks were evenly retracted. Quarters arch scans were made using a powder-free intraoral scanning device (Cerec AC, Omnicam, Sirona Dental Systems GmbH, Bensheim, Germany) (Video 1). The design mode of the restoration was completed using the Biogeneric Copy (Cerec SW 4.6) and enabling the program to copy a primary tooth no. 64 from a study children's model (Kavo Dental, Charlotte, USA). The software optical images included, as stated: the “upper jaw,” the “lower jaw,” the “buccal,” and the “biocopy upper.” In the next step, the software automatically aligns the upper and lower jaws and articulates the models in the maximum intercuspal position. The gingival margins were defined automatically and manually designed using the “draw margin” tool (). Cerec SW 4.6 automatically calculates the insertion axis and also provides tools to adjust the restoration design, including the occlusal and interproximal occlusal contact points. In the milling preview, the restoration was placed in a hybrid ceramic block (Vita Enamic, Vita Zahnfabrik, H. Rauter GmbH & Co. KG, Germany) with a shade of 2M2-HT and EM-10 size (LOT 56802, REF20170404), that was automatically determined by the software with the shade analysis tool. The milling of the block was completed in the “Standard” mode and milled with the CEREC MC X milling unit and diamond burs (step bur 12S, cylinder pointed bur 10) (). After the completion of the milling procedure, the crown was hand polished according to the specifications from the manufacturer. The restoration was cleaned with alcohol and dried with oil- and water-free air. The inner surface of the crown was sandblasted with Al2O3 at two bar pressure followed by etching with 5% hydrofluoric acid for 60 seconds and then placed in an ultrasonic bath for 5 minutes. The crown was then cemented with the self-adhesive resin cement (Solocem, Coltene, Whaledent, Altstatten, Switzerland) according to the instructions from the manufacturer and polymerized with a Bluephase LED device at 1.200 mW/cm2 (Ivoclar Vivadent, Schaan, Liechtenstein). The resin cement was set and excesses were removed from the interproximal space with dental floss, the occlusion was checked, and instructions for oral hygiene were given. The editing time of the restoration had a duration of 2 minutes, the milling time took 9 minutes, while the total chairside time was 50 minutes. Initial and final intraoral pictures are presented in and.
