Purpose: Scientific evidence is limited regarding the long-term (>10 years) outcomes of large enough numbers of implants (>500) to allow for reliable comparison of subgroups. The purpose of this study was to analyze the outcomes of dental implants placed in an active University Clinic setting and followed for up to 20 years.
Materials And Methods: Data documenting the implant placement, prosthetic reconstruction, and annual follow-up of patients treated at Frankfurt University were extracted from a Structured Query Language database and patients' written records and evaluated statistically.
Results: Between April of 1991 and May of 2011, 12,737 ANKYLOS® (DENTSPLY Implants Manufacturing GmbH, Mannheim, Germany) implants were placed in 4,206 patients for a variety of clinical indications. The Kaplan-Meier cumulative survival rate (CSR) was 93.3% after 204 months. Most of the failures (198/1.6%) occurred during the first year after implant placement and before prosthesis delivery. A significantly higher (p < .001) number of implants placed in the mandible and in hard quality bone failed than those placed in the maxilla or in weak and normal quality bone. Female patients had significantly higher CSRs (93.7% 204 months) than male patients (92.8% 204 months/p = .029). The implants showed low rates of peri-implant bone loss after 204 months (horizontal: ≤1 mm: 85.7%, vertical: ≤1 mm: 85.2%).
Conclusion: ANKYLOS dental implants followed for up to 20 years have high CSRs and low rates of peri-implant bone loss.

Objectives: To identify changes in immunological, microbiological, and histological biomarkers that may indicate resistance during the induction phase and resilience during the resolution phase of experimental peri-implant mucositis (PiM).
Materials And Methods: The search was performed in MEDLINE, EMBASE, Web of Science, SCOPUS, Cochrane Library, and LILACS databases. Prospective interventional studies assessing biomarkers during experimental PiM were included.

Crestal placement of short plateau implants in compromised jaws may cause implant failure due to bone overstress. The aim was to evaluate the impact of different sized implants on adjacent bone overload and the implant load-bearing ability in terms of the proposed index-ultimate functional load (UFL). Three-dimensional models of osseointegrated implants placed in types III and IV bone were analysed by the FEM for the case of patient-specific variations in cortical bone elasticity modulus.

Periodontal and peri-implant diseases are a significant public health problem worldwide, resulting in the destruction of the supporting bone. These bone defects can cause esthetic problems, increased relapse rate, and eventually tooth loss. The etiology of periodontal disease involves an influx of innate immune cells (neutrophils and monocytes) and upregulation of local inflammatory cytokines in the gingiva.

Background/objectives: Peri-implantitis often necessitates surgical intervention, with implantoplasty being proposed as a decontamination method in resective surgeries. This mechanical cleaning technique aims to halt disease progression by removing bacterial colonies. However, implantoplasty may compromise mechanical properties, reduce corrosion resistance, and lead to cytotoxic effects due to titanium particle release.

Advancements in implant design, surface characteristics, and surgical protocols have made implant restorations safe and highly predictable procedures. Bone metabolism plays a central role in the success of implant therapy. Diabetes mellitus is a significant disease impacting bone metabolism, particularly during the initial stages of osseointegration and in long-term survival.
