Introduction: With the rise of digital workflow, the production of implant guides is becoming increasingly easy and reproducible. The objective is to obtain an optimal correlation between the prosthetic and implant axis to ensuring the "X jaw - one day" concept in the short term and a sustainable technique in a long term TECHNIQUE: This approach requires a strict and rigorous preoperative evaluation. The data recording steps allow a complete visualization of the case and are used to custom the guide. The bone support is surmounted by several stages (positioning guide, drilling guide and the future temporary prosthesis).
Conclusion: Despite the time-consuming nature, this technique provides a reliable and reproducible protocol for immediate loading without compromising the prosthetic axis.

Background: In recent years, advancements in digital dentistry have provided new opportunities for more predictable and efficient treatment options, particularly in patients with failing dentition. This study aimed to evaluate the effectiveness and accuracy of a fully digital workflow using stackable surgical templates for complete dental arch rehabilitation with implant-supported fixed restorations.
Methods: Four patients, comprising two males and two females with a mean age of 66 years, were included in this case series.

Background: The cortical shell technique is frequently associated with technical drawbacks, such as the lack of anatomical guidance during shell harvest and graft. This study aims to assess the horizontal bone gain and accuracy of a digitalized protocol that incorporates two interlocking patient-specific stackable guides (PSSGs) to control the shell harvest, positioning, and fixation.
Patients And Methods: Twenty patients with deficient anterior mandibles were randomly allocated; 10 patients received freehand symphyseal shell harvest and fixation (the control group), whereas the other 10 received fully guided harvest and graft (study group) using (PSSGs), the first aided an accurate shell harvest, whereas the second conveyed shell fixation.

Background/aim: With new therapies for metastatic prostate cancer, patients are living longer, increasing the need for better understanding of the impact of comorbid disease. Prescription medications may risk-stratify patients independent of established methods, such as the Charlson Comorbidity Index (CCI) and guide treatment selection.
Patients And Methods: In a nationwide retrospective study of US Veterans, we used multivariable logistic regression and Cox proportional hazard modeling to evaluate the association between number and class of prescription medications and overall survival (OS) with age, race, body-mass index, prostate specific antigen (PSA), and Charlson comorbidities as covariates in veterans treated for de novo metastatic hormone sensitive prostate cancer (mHSPC) between 2010-2021.

Purpose: As the population gets older, the prevalence of complete or partial tooth loss is increasing, significantly impacting people's quality of life. Scientific research demonstrates that implant-fixed complete dentures offer high levels of satisfaction. In certain cases, tooth loss can lead to significant bone atrophy, necessitating pre-implant bone reconstruction.

Objective: The aim of this report is to present the complete workflow of 3D virtual patient for planning and performing implant surgery with magnetically retained 3D-printed stackable guides.
Clinical Considerations: A 3D-printed stackable system was proposed based on bone, dental, and facial references. Initially, a 66-year-old male patient was digitalized through photographs, cone beam computed tomography, and intraoral scans (Virtuo Vivo, Straumann).
