The reverse impression technique consists of the extraoral digitalization of an implant-supported interim prosthesis by placing scan analogs in an interim implant-supported prosthesis. The technique facilitates the recording of implant and tooth positions and allows the digitalization of the volumetric dimensions of the interim restoration. However, it is not able to register soft tissue changes during the healing process. A modified reverse impression technique is described to facilitate capturing the current dimensions and soft tissue information at the time of the definitive implant scan. Additionally, the modified technique includes the use of a verification device. The extraoral digitalization of the verification device minimizes complications caused by the lack of passive fit of the milled interim polymethyl methacrylate prosthesis.

Introduction/objective: Schizophrenia with substance use disorder is a complex clinical condition that may increase treatment resistance. Cannabis use disorder is frequently associated with psychosis and the causal link has still to be defined. Partial D2/3 agonists may ensure limbic dopamine release normalization while avoiding reduced frontocortical dopamine release, which would contribute to negative symptoms.

Objectives: Buprenorphine has recently emerged as a prehospital treatment for opioid use disorder. Limited data exist regarding the implementation of prehospital buprenorphine programs. Our objective was to describe the development, deployment, lessons learned, and ongoing evolution of the Wake County EMS buprenorphine program using data from the first year following implementation.

The reverse scan technique offers several advantages, such as improvements of accuracy and visibility of critical anatomical structures, minimizing chair time, and providing better patient comfort. This was a case report successfully employing the reverse scan technique. A 72-year-old male patient desired to restore his teeth in both jaws, as he experienced difficulty eating and had never worn dentures.

Article Synopsis
- Electroconvulsive therapy (ECT) is an effective treatment for persistent psychiatric disorders, though post-ECT fever is rare and not widely reported.
- A case study of a 27-year-old woman with bipolar disorder showed she experienced multiple fever episodes after ECT, with diagnostic tests indicating inflammation but no signs of infection or serious syndromes.
- The findings suggest that the fever may be a benign inflammatory response to ECT, allowing for the continued use of ECT to achieve therapeutic benefits.
Effect of Abutment Tooth Geometry On The Accuracy of Fixed Prosthodontics Casts Obtained by Digital and Analog Workflows-In Vitro Study.

Article Synopsis
- The study aimed to compare the accuracy of dental casts for fixed dental prostheses (FDPs) made through digital versus traditional (analog) methods, specifically looking at how the shape of the abutment teeth influences this accuracy.
- Researchers used intraoral scanning and various additive manufacturing techniques to create both digital and plaster casts, assessing their accuracy through measurement deviations compared to a reference model.
- Results showed that both the manufacturing technique and the geometry of the abutment teeth significantly impacted the accuracy of the casts, indicating that not all methods yield equally precise outcomes depending on these variables.
