Positional Trueness with Different Titanium Base Bonding Techniques for Single Implant Crowns: In Vitro Evaluation of Model-Free Workflow Versus Additively Manufactured Models.

Objectives: To compare the positional trueness of implant-crown bonding to titanium bases (Ti-bases) using different bonding protocols.

Materials And Methods: A nonprecious alloy model with a single implant at the mandibular right first molar site was digitized, then a single implant crown was designed. The crown was milled, adhesively cemented on a Ti-base, and screw-retained on the implant in the master model to obtain a reference scan.

This second and final part of the publication on the topic of sustainability in dental practices deals with the so-called workplace management, which describes the work processes and the consumption of energy and materials in the practice itself. Waste management is also addressed, which discusses the path of resources from the practice to disposal and recycling. Finally, an example from materials research is presented using implants.

[Sustainable dentistry - Part I: Sustainability and pre-workplace management].

Sustainability in dental practices is playing an increasingly important role. External and internal factors have an influence on the emissions of a practice. The external factors include the domains of politics, science, and education.
