ImplantFormer: Vision Transformer based Implant Position Regression Using Dental CBCT Data [PDF]
Neural Computing and Applications 2024, 2022 Implant prosthesis is the most appropriate treatment for dentition defect or dentition loss, which usually involves a surgical guide design process to decide the implant position. However, such design heavily relies on the subjective experiences of dentists.

Local tissue effects and peri-implant bone healing induced by implant surface treatment: an in vivo study in the sheep [PDF]
, 2021 Objective: The aim of this study was to assess, through biological analysis, the local effects and osseointegration of dental implants incorporating surface micro/nanofeatures compared to implants of identical design without surface treatment. Background: Known to impact bone cell behavior, surface chemical and topography modifications target improved ...

Modeling the debonding process of osseointegrated implants due to coupled adhesion and friction [PDF]
, 2021 Cementless implants have become widely used for total hip replacement surgery. The long-term stability of these implants is achieved by bone growing around and into the porous surface of the implant, a process called osseointegration. However, debonding of the bone-implant interface can still occur due to aseptic implant loosening and insufficient ...

Design and Implementation of a Hybrid Wireless Power and Communication System for Medical Implants [PDF]
2023 IEEE MTT-S International Microwave Biomedical Conference
(IMBioC), 2023 Data collection and analysis from multiple implant nodes in humans can provide targeted medicine and treatment strategies that can prevent many chronic diseases. This data can be collected for a long time and processed using artificial intelligence (AI) techniques in a medical network for early detection and prevention of diseases.

Point Cloud Diffusion Models for Automatic Implant Generation [PDF]
, 2023 Advances in 3D printing of biocompatible materials make patient-specific implants increasingly popular. The design of these implants is, however, still a tedious and largely manual process. Existing approaches to automate implant generation are mainly based on 3D U-Net architectures on downsampled or patch-wise data, which can result in a loss of ...

TCSloT: Text Guided 3D Context and Slope Aware Triple Network for Dental Implant Position Prediction [PDF]
arXiv, 2023 In implant prosthesis treatment, the surgical guide of implant is used to ensure accurate implantation. However, such design heavily relies on the manual location of the implant position. When deep neural network has been proposed to assist the dentist in locating the implant position, most of them take a single slice as input, which do not fully ...

Computer-aided implant design for the restoration of cranial defects [PDF]
Scientific Reports 7, Article number: 4199 (2017), 2017 Patient-specific cranial implants are important and necessary in the surgery of cranial defect restoration. However, traditional methods of manual design of cranial implants are complicated and time-consuming. Our purpose is to develop a novel software named EasyCrania to design the cranial implants conveniently and efficiently.

Towards Deterministic Creation of Single Photon Sources in Diamond using In-Situ Ion Counting [PDF]
arXiv, 2021 We present an in-situ counted ion implantation experiment reducing the error on the ion number to 5 % enabling the fabrication of high-yield single photon emitter devices in wide bandgap semiconductors for quantum applications. Typical focused ion beam implantation relies on knowing the beam current and setting a pulse length of the ion pulse to define

Stress shielding at the bone-implant interface: influence of surface roughness and of the bone-implant contact ratio [PDF]
, 2020 Short and long-term stabilities of cementless implants are strongly determined by the interfacial load transfer between implants and bone tissue. Stress-shielding effects arise from shear stresses due to the difference of material properties between bone and the implant.

Approximate Expressions to the Reactive Near-Field Losses of Body-Implanted Antennas [PDF]
arXiv, 2022 Implantable bioelectronics often relies on an RF-wireless link for communication and/or remote powering. Propagation through biological media is very lossy, and previous work has shown that these losses can be separated into three parts: the losses incurred by the propagating fields, the reflections at media interfaces, and the coupling of the reactive
