Comparing Implant Macrodesigns and Their Impact on Stability: A Year-Long Clinical Study.
Medicina (Kaunas)
September 2024
Department of Dentistry, Faculty of Medical Sciences, University of Kragujevac, 34000 Kragujevac, Serbia.
: The aim of this study was to clinically evaluate the primary and secondary stability of dental implants with different macrodesigns using resonance frequency analysis and to determine whether implant design and length influence implant stability. : This study included 48 healthy patients receiving dental implants, and a pre-implant planning protocol was used, which involved detailed bone analysis, clinical examinations, and Cone beam computed tomography (CBCT) analysis. The implants were of various types and dimensions (Alpha-Bio Tec (Israel), DFI, SPI, and NEO), and the surgical procedures were performed using standard methods.

September 2024
Biomaterials Department, Faculty of Dentistry, University of Alexandria, Alexandria, Egypt.
Background: Implant-retained obturators for maxillectomy cases have several advantages over traditional obturators but prosthetic design for specific conditions after maxillary resection has several challenges and the appropriate implant placement configuration is essential for improving retention and the stability of the implant-retained obturator.
Objectives: The present study aimed to assess the retention force of using linear and nonlinear implant placement configurations using ball and socket attachment in implant-retained obturators at the initial retention and after simulation of six months of use.
Materials And Methods: Two identical epoxy resin maxillary models of a completely edentulous unilateral maxillary defect (Brown's class IIb) were used for implant placement, in the first model three implants were arranged with linear placement configuration, and in the second model three implants were arranged in nonlinear placement configuration.
Mandibular Fixed Prosthesis With a 3D-Printed Subperiosteal Implant: A Case Report.
J Oral Implantol
August 2024
Department of Plastic,Reconstructive and Aesthetic Surgery, Faculty of Medicine, Firat University, Turkey.
This case report aims to present the successful restoration of the atrophic partially edentulous posterior mandible using custom-made subperiosteal implants. The fixed prosthesis restoration was achieved using computer-aided design and computer-aided manufacturing technologies and 3D metal printing methods. The partially edentulous 58-year-old patient expressed a preference not to undergo bone augmentation procedures.

Int J Implant Dent
October 2023
Shanghai University of Medicine and Health Sciences, Shanghai, 201318, People's Republic of China.
Purpose: This review aimed to reveal the influence of implant guides on surgical accuracy with regard to supporting types, manufacturing methods and design (including fixation screws and sleeves).
Methods: A literature search related to accuracy of surgical guides for dental implantation was performed in Web of Science and PubMed. Studies with in vivo or in vitro deviation data published in recent 5 years (2018-2022) were included and assessed by Newcastle-Ottawa Scale with regard to risk of bias and reliability degree of clinical studies.
Achieving optimal implant esthetics using a team approach Part 1 a review of evidence-based criteria in implant treatment.

As dental implants have evolved into a universally accepted treatment option, it is essential to identify nuances of the peri-implant complex and their impact on treatment given the increasing evidence of peri-implantitis and implant loss. A thorough knowledge of anatomy and biology, careful treatment planning, correct placement, prosthetic and occlusal design, and proper long-term maintenance all play a role in dental implant therapy. The goal of this part 1 presentation is to review evidence-based criteria in implant treatment including the surgical and restorative parameters, and the desired implant features, with the objective of achieving predictable results that improve the longevity of the implant and restoration, maintain peri-implant health, and optimize the esthetic outcome.
