Computer-aided design and computer-aided manufacturing (CAD/CAM) systems have historically proven to produce high-quality single-tooth restorations. In recent years, advancements in the scope of scanning technologies in the dental profession have provided a potential platform for complex digital workflows involving complete mouth rehabilitation. This article details the use of both analog and digital methods for reestablishing occlusal function and esthetics in a clinical case involving extreme tooth wear and loss of vertical dimension. The use of both methods was necessary in this case to achieve optimal occlusion, an esthetic result, and a harmonious dentition.

The initial onset of the novel coronavirus, COVID-19, in humans was first reported in Wuhan, China, in December 2019. Due to rapidly spreading the COVID-19 outbreak worldwide, the World Health Organization declared a pandemic on March 11th, 2020 that has globally increased to 62,844,837 cases worldwide with a total of 1,465,144 confirmed deaths, as of December 1st, 2020. With the ever-evolving nature of COVID-19, it is imperative that healthcare professionals, especially those in the dental profession, remain educated and prepared with the best inclusive practices to ensure the safety of their patients, staff, and themselves. A review of guidelines from organizations around the world has been conducted to evaluate the most comprehensive strategies dental practices can take to minimize the risk of disease transmission during the pandemic and the post-pandemic future.

Substance use disorder (SUD) is a relapsing brain disorder characterized by compulsion and chronicity. SUD has detrimental effects on oral health. Drugs and alcohol negatively impact oral health by inducing a myriad of orofacial conditions including xerostomia, dental caries, periodontal disease, bruxism, pre-cancer and cancer, to name a few. Limited recommendations are available for dental professionals on how best to manage patients afflicted with SUD. The aim of this article is to review the oral health consequences of alcohol and commonly abused drugs to provide guidelines for the public health community and dental professionals. The United Nations estimates that a quarter billion people, representing five per cent of the global adult population, used drugs at least once in 2015. Developing public health interventions that include the participation of dental professionals and access to dental services for persons afflicted with SUD could play a critical role in improving their quality of life, their recovery, and their reintroduction into society.

Use of diode lasers in dentistry has grown in popularity over the years. When used by a properly trained and licensed dental professional and proper protocols are observed, efficacy of diode laser use for many procedures is possible. It is important that specific protocols be followed when using the diode laser to ensure safety of both patients and providers.

The purpose of this article is to illustrate the accuracy of a digitally planned 3D-printed guide for an apicoectomy procedure. A three-dimensional image was acquired of the patient’s teeth using cone beam computed tomography (CBCT). In utilizing open source software, an intraoral scan of the patient is combined with the CBCT image to design a surgical guide for an apicoectomy procedure. The surgical guide was 3D-printed and utilized for surgical apicoectomy accuracy.

Predictable all ceramic restorations utilizing computer-aided design/computer-aided milling have been made possible by following carefully outlined directions. A combined understanding of the capabilities of software, the milling unit, ceramic properties and the bonding process allows a dentist to create indirect restorations that exhibit desirable qualities.

Computer-aided design/computer-aided milling (CAD/CAM) has grown in popularity over the last decade and is here to stay! The technology as a whole and the materials of choice are continuously evolving, allowing us to fabricate predictable restorations. Perhaps even more importantly, CAD/CAM assists us in becoming better dentists. When proper technique and attention to detail are observed in treatment planning, preparing teeth, and scanning and bonding restorations, we as dentists can predictably fabricate an esthetic and functional restoration for the patient. This chapter is written based on our experiences with Sirona’s CEREC and Planmeca’s E4D systems. The authors bring to light some basic principles that are applicable to any milled restoration as we expect more systems to emerge in the years to come.

The following chapter will focus on implantology as it pertains to the general practitioner. The general practitioner is responsible for developing the restorative plan that will dictate treatment from start to finish. Oftentimes with implants, it is a team-based approach that will involve multiple specialties. For a general dentist, the standard of care is to have the ability to develop a treatment plan for a patient and discuss the option of having implants as alternatives to other dental treatments. A basic understanding of implant diagnosis and treatment planning, pre-prosthetic and surgical planning, restorative guidelines, and complications will be presented.

Urban forestry programs that recognize the importance of expanding professional skills of managers and arborists while simultaneously establishing an on-going flow of information to the public can more effectively preserve and expand an urban forest.
