Calcium phosphate-based materials are widely used in dental applications due to their bioactivity and compositional similarity to mineralized tissues. This narrative review synthesizes the peer-reviewed literature published between 2014 and 2024 identified using Scopus, Web of Science, and PubMed, with a specific focus on digitally manufactured calcium phosphate-based dental materials. This review integrates evidence on calcium phosphate phase chemistry and advanced material systems, material configurations compatible with digital workflows and digital manufacturing routes. Emphasis is placed on how fabrication parameters and post-processing—particularly thermal treatment and densification—affect phase composition, microstructure/porosity, mechanical performance, and biological behavior. The current limitations reported in the literature are addressed, including material brittleness, dimensional instability during sintering, heterogeneity of fabrication protocols, and the lack of standardized evaluation methods. The restricted availability of long-term and clinically relevant evidence is also discussed in relation to translational applications. Future research should prioritize well-designed clinical studies to validate the use of digitally manufactured calcium phosphate-based materials in guided bone regeneration, socket preservation, and implant-related procedures.

Background/Objectives: The rapid evolution of digital technologies has significantly transformed prosthodontic workflows, improving clinical precision, communication, and patient satisfaction. However, the extent to which dental professionals perceive, integrate, and evaluate these technologies remains insufficiently standardized. This study aimed to develop and validate a questionnaire for assessing perceptions, attitudes, perceived advantages, barriers, and future intentions regarding the use of digital technologies in prosthodontic practice. Methods: A cross-sectional survey was conducted among 420 dental professionals (305 dentists and 115 dental technicians) from Northeastern Romania. The 27-item questionnaire, structured on five theoretical dimensions, was distributed online via the Survio platform. Internal consistency was assessed using Cronbach’s Alpha, and construct validity was analyzed through Exploratory Factor Analysis (Principal Component Analysis with Varimax rotation). Conclusions: Cronbach’s Alpha coefficients ranged from 0.700 to 0.799 across the five dimensions, indicating acceptable to very good internal reliability. The Kaiser–Meyer–Olkin value (0.646) and Bartlett’s Test of Sphericity (p < 0.001) confirmed data suitability for factor analysis. The validated questionnaire represents a reliable and conceptually coherent tool for evaluating professional perspectives on digitalization in prosthodontics. Its application can inform educational strategies, guide institutional investments, and support a balanced transition toward integrated digital workflows in clinical and laboratory settings.
