“…In Switzerland, a survey of members of the Swiss Dental Association revealed that a chair-side CAD/CAM system was present in 23% of the surveyed practices [ 26 ]. A recent study among the USA Navy dental clinics and laboratories demonstrated that, by June 2017, more than a third of the provided indirect restorations (38.1%) were fabricated by a CAD/CAM system [ 27 ]. Moreover, analysis of the records illustrated progressive increase in the number of CAD/CAM fabricated restorations over the last 5 years.…”

“…Moreover, analysis of the records illustrated progressive increase in the number of CAD/CAM fabricated restorations over the last 5 years. Due to various advantages, the authors speculated greater implementation of digital dentistry among Navy dentists in the coming future [ 27 ]. Few surveys targeted dental students and sought their attitudes towards integration of digital dentistry into dental education and clinical practice, including CAD/CAM technology.…”

The application of computer-aided design and computer-aided manufacturing (CAD/CAM) technology in dentistry has rapidly expanded. This survey aimed to investigate attitudes and current practice of dentists in Riyadh, Saudi Arabia regarding chair-side CAD/CAM technology. An online questionnaire was prepared and sent to a convenience sample of dentists in Riyadh. Questions related to practice aspects of chair-side CAD/CAM system, attitudes and training were presented. A total of 114 questionnaires were completed (77.6% response rate). Study population comprised dentists of a wide range of clinical experience who are working in the various regions of Riyadh city, Saudi Arabia. Of the participants, 27.2% indicated the presence of a chair-side CAD/CAM system at their current workplace and 57% used the chair-side CAD/CAM in the fabrication of dental crowns. The vast majority of participants (81%) believe that the overall quality of chair-side CAD/CAM restorations is at least as good as those fabricated by a lab technician or much better. Most responding dentists considered the chair-side CAD/CAM system as important in terms of time saving, boosting the number of visiting patients and income improvement. The willingness to dedicate the time and effort to learn the chair-side CAD/CAM technology was apparent amid a high proportion of dentists (75.4%). The findings of this pilot survey reflect broad satisfaction and positive attitude among the surveyed dentists towards use and outcome of chair-side CAD/CAM technology in the dental clinical practice. It seems that the CAD/CAM technology has infiltrated into the workflow of Saudi dental practices with speculations of growing implementation among the wider sector of dental practitioners in the future.

“…Interest in chairside computer-aided design and computer-aided manufacturing (CAD/CAM) has been growing since its introduction to dentistry in the 1980s [1][2][3]. Currently, chairside restorations are fabricated in a monolithic manner using glass ceramics [4], mainly lithium disilicate (LD).…”

“…This marks a strong diversion from the traditional metal‐ceramic construction, which was made primarily by hand. This digital change is echoed in findings from a study of United States Navy clinicians, who increased CAD/CAM units from 12% in 2012 to 38% in 2017 . This trend was supported in a survey of UK and Irish dental technicians, who reported that a majority of technicians use some sort of CAD/CAM technology in their workflow .…”

Purpose: In-laboratory assessment by laboratory technicians may offer insight to increase clinical success of dental crowns, and research in this area is lacking. Materials and Methods: Dentists in the National Dental Practice-Based Research Network enrolled patients in a study about single-unit crowns; laboratory technicians evaluated the quality of tooth preparations and impressions. The primary outcome for each crown was clinical acceptability (CAC), as judged by the treating dentist. A secondary outcome was "Goodness of Fit (GOF)," a composite score of several aspects of clinical fit, also judged by the study dentist. A mixed-effects logistic regression was used to analyze associations between laboratory technician ratings and the CAC and GOF. Results: Dentists (n = 205) evaluated 3731 crowns. Technicians ranked the marginal detail of impressions as good or excellent in 92% of cases; other aspects of the impression were ranked good or excellent 88% of the time. Regarding tooth preparation, about 90% of preparations were considered adequate (neither excessive nor inadequate reduction). Factors associated with higher CAC were more preparation taper, and use of optical imaging. Factors associated with better GOF were higher impression quality, greater occlusal reduction, more preparation taper, and optical imaging.Conclusions: Overall quality of preparations and impressions was very high, as evaluated by laboratory technicians. Several clinical parameters were associated with higher CAC and GOF. Clinicians who struggle with crown remakes might consider less conservative tooth preparation, as well as using digital impression technology.Despite careful attention to detail and the use of current techniques and materials, dentists still must remake crowns that do not fit clinically; the remake rate approaches 4%. 1 Such remakes require additional time and effort from the dentist, patient, and laboratory. It is often difficult to know why one particular crown must be remade, yet the next one-fabricated using the same laboratory and techniques-may fit nicely on the next patient. Possible sources of error which could cause a crown to be clinically unacceptable include (1) inadequate detail in the impression; (2) insufficient occlusal reduction; (3) insufficient axial reduction; (4) distorted impressions; (5) poor mounting in laboratory, or incorrect interocclusal record; (6) improper preparation design; (7) poor laboratory work; and (8) unknown factors.The quality of impressions submitted to dental laboratories has been criticized in the literature, with as many as 90% of impressions having an error. 2 One study of 1157 impressions found that 86% of impressions had at least one error, with over half having to do with the preparation finish line. 3 Errors were caused by tissue over the finish line, voids in the impression,
