Purpose: The aim of this study was to investigate the association of hypertension and antihypertensive drugs with the failure of osseointegrated dental implants.
Materials And Methods: This study conformed to STROBE Guidelines regarding retrospective studies. Data from 602 medical records of patients who received rehabilitation treatment with osseointegrated implants between 2000 and 2017, completed at least 6 months before the study, were analyzed. Data on age, sex, presence or absence of hypertension, use or not of antihypertensive drugs, number of placed and lost implants, and type of prosthetic rehabilitation were collected. Statistical chi-square tests and the Fisher exact test were used to analyze the variables with implant loss, using a significance level of P < .05.
Results: One thousand eight hundred eighty-seven implants were placed with a success rate of 97.51% (47 implants lost in 41 patients). Of the 602 patients, 71.43% (432) were normotensive and 28.36% (171) were hypertensive. The success rate of implants in the normotensive group was 93.28%, and in the hypertensive group, it was 92.99%, with no statistical difference between the groups (P = .958). Of these patients, the success rate among the hypertensive group was similar for medication users (92.5%) and for nonusers (94.1%), with no statistically significant difference (P = .939).
Conclusion: The presence of hypertension, as well as the use of antihypertensives, could not be associated with the failure of osseointegrated implants.

Background: Many patients with a lower limb socket-suspended prothesis experience socket-related problems, such as pain, chronic skin conditions, and mechanical problems, and as a result, health-related quality of life (HRQoL) is often negatively affected. A bone-anchored prosthesis can overcome these problems and improve HRQoL, but these prostheses have potential downsides as well. A valid and reliable tool to assess potential candidates for surgery concerning a favorable risk-benefit ratio between potential complications related to bone-anchored prostheses and improvements in HRQoL is not available yet.

Introduction/objectives: Failures of osseointegrated implants pose a significant challenge in the medical field, often attributed to prolonged osseointegration periods and bacterial infections. Functionalization of Titanium Dioxide Nanotubes (TNTs) has emerged as a promising strategy to improve osseointegration and mitigate infections. This study aims to conduct a bibliometric analysis and systematic review to identify trends, gaps, and advancements in research on the functionalization of TNTs for osseointegration improvement.

This study numerically investigates the impact of different loading modes on the biomechanical response of an osseointegrated dental implant. While finite element modeling is commonly employed to investigate the mechanical behavior of dental implants, several models lack physiological accuracy in their loading conditions, omitting occlusal contact points that influence stress distribution in periimplant bone. Using 3D finite element modeling and analysis, stress distributions at the bone-implant interface are evaluated under both physiological loading, incorporating natural occlusal contact points, and non-physiological loading conditions, with a focus on load transmission mechanisms and the potential risk of bone overloading.

Background: The alignment of a bone-anchored prosthesis has consequences for the external moments around the residual joints and implant, and these external moments can lead to serious negative long-term effects. A clear understanding of the relationship between transtibial prosthetic alignment and external joint and implant moment for bone-anchored prosthetic users is still lacking.
Research Question: What is the effect of systematic frontal plane prosthetic alignment changes on lower limb external joint moments in people with a transtibial bone-anchored prosthesis?
Methods: Participants underwent gait analysis on an instrumented dual belt treadmill.

Osseointegrated dental implants represent a successful treatment modality for partial and complete edentulism. However, concerns persist regarding their impact on adjacent natural teeth. Conflicting literature exists regarding complications such as caries, mobility, and fractures in neighboring teeth, with few studies comparing these effects with those observed in contralateral natural teeth.
