A 3D printed ultra-short dental implant based on lattice structures and ZIRCONIA/CaSiO combination.

Additive Manufacturing (AM) enables the generation of complex geometries and controlled internal cavities that are so interesting for the biomedical industry due to the benefits they provide in terms of osseointegration and bone growth. These technologies enable the manufacturing of the so-called lattice structures that are cells with different geometries and internal pores joint together for the formation of scaffold-type structures. In this context, the present paper analyses the feasibility of using diamond-type lattice structures and topology optimisation for the re-design of a dental implant.

Familiarity and implementation of academicians of dental schools regarding the application of photodynamic therapy in dentistry: A need to incorporate in the dental curriculum.

Background: The present cross-sectional study aimed to evaluate the knowledge, behavior, and attitudes of academicians from dental schools in Riyadh, Saudi Arabia towards the use of photodynamic therapy (PDT) in dentistry.

Methods: A self-administered questionnaire to a total of 289 academicians from the dental training faculty (DTF) was distributed to six dental schools in Riyadh, Saudi Arabia during 3 months of the study period. The questionnaire consisted of four main sections with 17 items that dealt with: demographic data, awareness, and knowledge of dental academician regarding PDT technique, and the interest of the dental academician in implementation the PDT technique, detailed knowledge, and background about PDT use followed by the role and integration of PDT technique and its theoretical knowledge in the curriculum and clinical practice.
