“…This observation was in agreement with data from recent published studies on the clinical short/medium‐term performance of zirconia‐based ceramic single crowns . Besides the ceramic system selected, the choice of the luting agent is important because the ceramic fracture strength decreases as the restoration ages and the bond strength degrades in the oral cavity . Because of its high flexural strength, zirconia can be conventionally cemented just like metal ceramic crowns, without the need for any pretreatment, or bonded with adhesive resin cements .…”

“…For this young patient with vital teeth and retentive preparations, resin‐modified GIC was chosen due to its lower technique sensitivity, its good long‐term results, and its potential for fluoride release. Although this luting agent provides inferior bond strength compared with resin cements, in vitro studies have demonstrated an improved retention strength for zirconia crowns compared to zinc phosphate and GIC cements …”

This manuscript describes an interdisciplinary approach over a period of 8 years combining surgical and prosthodontic treatment of a young patient diagnosed with hypocalcified-type amelogenesis imperfecta and anterior open bite. The treatment procedures included transitional restorations, orthodontic treatment, and maxillofacial surgery with a one-piece Le Fort I osteotomy, bilateral mandibular osteotomy, and genioplasty. The definitive prosthetic rehabilitation consisted of 28 zirconia-based ceramic single crowns restoring both esthetics and function. Photographs and radiographs associated with clinical evaluation were used in the maintenance period. Two-year follow-up revealed satisfactory results and no deterioration in the restorations.

“…Setting patient expectations is presented as a factor in clinical success, as are the esthetic demands of the patient . Various articles document the potential success and clinical longevity of crowns, including crowns of various materials, from gold to zirconia, and differing manufacturing techniques, from handcrafted stacked porcelain to in‐office milling …”

Purpose Some crowns returned from the laboratory are clinically unacceptable, and dentists must remake them. The objectives of this study were to: (1) quantify the remake rate of single‐unit crowns; and (2) identify factors significantly associated with crown remakes and intraoral fit. Materials and Methods Dentists participating in the National Dental Practice‐Based Research Network recruited patients needing crowns and documented fabrication techniques, patient characteristics, and outcomes. Crowns were considered clinically acceptable or rejected. Also, various aspects of the clinical fit of the crown were graded and categorized as ‘Goodness of Fit (GOF).’ Dentist and patient characteristics were tested statistically for associations with crown acceptability and GOF. Results More than 200 dentists participated in this study (N = 205) and evaluated 3750 single‐unit crowns. The mean age (years) of patients receiving a crown was 55. The remake rate for crowns was 3.8%. The range of rejection rates among individual practitioners was 0% to 42%. Most clinicians (118, or 58%) did not reject any crowns; all rejections came from 42% of the clinicians (n = 87). The most common reasons for rejections were proximal misfit, marginal errors, and esthetic failures. Fewer years in practice was significantly associated with lower crown success rates and lower fit scores. GOF was also associated with practice busyness and patient insurance status, patient gender (dentists reported better fit for female patients), and patient ethnicity. Conclusions The crown remake rate in this study was about 4%. Remakes and crown GOF were associated with certain dentist and practice characteristics.

“…The combination of an intraoral camera, design software, and a milling unit makes it possible to avoid imprints and models and to finish the restoration in a single treatment session. Numerous in vitro [28][29][30][31][32][33] and in vivo 14,23,25,34,35 studies have determined that restorations made with the Cerec system or other CAD/CAM techniques fit accurately and have sufficient fracture strength. With the Cerec system, a variety of ceramic materials can be processed, and CAD/CAM fabrication of either veneered or monolithic restorations can be achieved.…”
