Abstract:

Dental implants are a proven therapeutic option for replacing missing teeth, with positive long-term health outcomes. Dental implant performance is largely determined by the implant’s primary durability, which is affected by surgical procedure, bone quality and quantity, implant surface characteristics, implant geometry, and implant surface characteristics. The implant’s geometry and surface can be modified. The implant geometry and surface can be changed if needed to achieve good primary stability and long-term implant therapy effectiveness. Implant architecture refers to the implant’s three-

Abstract:

Titanium dental implants are one of the modalities to replace missing teeth. The release of titanium particles from the implant’s surface may modulate the immune cells, resulting in implant failure. However, little is known about the immune microenvironment that plays a role in peri-implant inflammation as a consequence of titanium particles. In this study, the peri-implant gingival tissues were collected from patients with failed implants, successful implants and no implants, and then a whole transcriptome analysis was performed.

Abstract:

Despite significant advances in neurosurgery, stable spinal reconstruction after total en bloc spondylectomy (TES) remains a challenge. This procedure standardly consists of replacing the vertebra with an implant and performing transpedicular fixation. However, standard serial implants do not always provide sufficient support and adequate load distribution, increasing the risks of instability, deformations and subsidence of the implant. It is therefore crucial to develop customized implants based on additive technologies. Three different implants were examined in this study: two polymeric impl

Abstract Objective. Intrafascicular peripheral nerve implants are key components in the development of bidirectional neuroprostheses such as touch-enabled bionic limbs for amputees.

Contraceptive Implants have been proven to be very effective hormonal birth control devices. This study aimed to evaluate the prevalence and pattern of uptake of implants among women of reproductive age in Bingham University Teaching Hospital (BHUTH), Jos Nigeria. It was a retrospective analysis of BHUTH family planning unit records between January 2022 and July 2024 totaling a period of 31 months. Out of the 1498 women who subscribed to family planning services during the study period, 485 clients accessed implants, which accounted for 30% prevalence. Levoplant (13%) was the highest followed

Background: Stress concentrated at an implant’s neck may affect bone-to-implant contact (BIC). The objective of this study was to evaluate four different implant neck designs using two different drilling protocols on the BIC. Methods: Ninety-six implants were inserted in 12 minipigs calvarium. Implants neck designs evaluated were: type 1–6 coronal flutes (CFs), 8 shallow microthreads (SMs); type 2–6 CFs,4 deep microthreads (DMs); type 3–4 DMs; type 4–2 CFs, 8 SMs. Two groups of forty-eight implants were inserted with a final drill diameter of 2.8 mm (DP1) or 3.2 mm (DP2).

Background: Polymethyl methacrylate (PMMA) cranioplasty, while widely prevalent, has limitations associated with freehand manual intraoperative molding. PMMA has been superseded by titanium or Polyetheretherketone implants, prefabricated commercially from preoperative CT scans, and boasting superior clinical and cosmetic outcomes. However, such services are extremely inaccessible and unaffordable in the lower-middle-income country (LMIC) settings.

There were statistically significant differences between Groups A (control) and B (rough surface) (P = .03). Implants with a rough surface seem to add resistance to the bone-implant interface compared with smooth titanium implants or implants treated with LLLT.

<strong>Abstract</strong> Clinicians who practice implant dentistry are still concerned about the life and longevity of dental implants in patients who have used anti-resorptive drugs. The alveolar bone must undergo significant remodelling to prepare the bone and surrounding tissues for surgery. Furthermore, throughout and after the dental implant's osseointegration phase, the bone around the implant fixture continuously remodels. Anti-resorptive drugs can hinder osseointegration and even cause medication-related osteonecrosis of the jaw (MRONJ). These drugs are used to decrease bone remodelli

Abstract:

Implants that show indications of problems but are not quite at the point of failure are referred to as failing implants. The long-term prognosis of the implant may be impacted by these problems, which can include mild to moderate peri-implant illnesses including peri-implant mucositis or modest bone loss. Moderate bone loss (usually less than 2 mm) and minor inflammation, such as peri-implant mucositis, are common symptoms of failing implants. One reversible stage of implant problems is represented by failing implants. Severe bone loss, peri-implantitis, or implant mobility are some of the wo
