Influence of Prosthetic Emergence Profile on Peri-Implant Marginal Bone Stability: A Comprehensive Review

Medicina, Journal Year: 2025, Volume and Issue: 61(3), P. 517 - 517

Published: March 17, 2025

The prosthetic emergence profile is a factor potentially affecting marginal bone level around dental implants. aim of this review to provide comprehensive analysis the influence on peri-implant bone-level stability. an important parameter in implant dentistry, reflecting stability implants, and it critical indicator long-term success. Minimizing loss implants key for maintaining function, supporting soft tissues, achieving predictable aesthetic outcomes. scientific literature presents various examples evidence angle designs loss. Several studies suggest that angles exceeding 30° convex may increase risk peri-implantitis resorption, while others find no significant correlation. Moreover, several demonstrated positive taper joint connections Although current remains diverse, essential prioritize cleanability minimize plaque accumulation successful implant-prosthetic restoration. Proper maintenance continuous follow-up monitor are beneficial obtaining stable optimal results.

Influencing factors and survival rates in immediate vs. delayed dental implant placement: a six-year retrospective analysis

Frontiers in Dental Medicine, Journal Year: 2025, Volume and Issue: 6

Published: April 29, 2025

This retrospective cohort study aimed to compare survival rates between immediate (≤24 h post-extraction) and delayed (3-4 months dental implants identify patient- site-specific risk factors for implant failure, with emphasis on anatomical site, sex, osteoporosis. We analyzed 1,500 (300 immediate, 1,200 delayed) from patients treated at the Guangdong Provincial Hospital of Traditional Chinese Medicine (2005-2023). Kaplan-Meier analysis evaluated cumulative over 72 months, Cox regression modeling assess predictors failure. Propensity score matching (PSM) addressed baseline covariate imbalances. Delayed exhibited significantly higher than (81.1% vs. 53.2%, p < 0.0001). Survival divergence intensified after 24 retaining 979 202 implants. Mandibular sites consistently outperformed maxillary in both strategies (delayed: 88.5% 72.2%; immediate: 70.5% 40.7%, Male sex (HR: 1.64, 95% CI: 1.28-1.88; 0.001) osteoporosis 2.50, 1.17-4.52; = 0.024) emerged as independent factors, while tobacco use, diabetes, hypertension showed no significant associations. PSM resolved most imbalances, post-matching standardized mean differences (SMD) <0.1 key covariates. implantation 3-4 post-extraction provides superior intermediate-term survival, particularly mandibular sites. individuals face elevated failure risks, warranting tailored clinical protocols. While remain viable, placement is recommended high-risk populations optimize long-term outcomes.

Resective surgical treatment of peri-implantitis: an integrative review

Oral & Implantology, Journal Year: 2025, Volume and Issue: 17(1), P. 50 - 59

Published: Feb. 12, 2025

Objectives: This review aimed to analyze the resective surgical treatment of peri-implantitis (PI), evaluating whether it is an effective approach. Methods: An electronic search was done through PubMed/MedLine and Online Knowledge Library (B-On) databases from 2011 2022. The section studies guided by reading title, abstract, full-text article. It included randomized controlled trials (RCTs), only clinical studies, articles in English language addressing PI, taking into account respective parameters: probing depth (PD), bleeding on (BoP), marginal bone loss (MBL), microbiological data. Results: According bibliographic research, we found 325 articles; therefore, seven were for integrated this review. Over 401 implants studied 221 patients diagnosed with PI treated different approaches. Two had a 24-month follow-up; one 12 months; two duration 36 3 study 6-month follow-up. Regarding mean age patients, average 59.3 years found. All both smoking non-smoking but these did not show any negative effects treatments PI. There large heterogeneity methods treating PI: (1) surgery osteoplasty surface debridement (implantoplasty, IP); (2) use medications/antiseptic (0.12% chlorhexidine + 0.05% cetylpyridinium chlorine) or acids (phosphoric acid 35%); (3) adjunctive laser. best PD reduction result obtained Bianchini et al.’s study, 75% decrease. %BoP present Papadopoulos al., 73% 67%, respectively, approaching isolated “open flap” adding MBL Englezos difference 4.9 mm. Conclusion: effectively reduced parameters (PD, BoP, MBl, inflammation) tissues affected More scientific evidence limited regarding success PI; however, additional more significant number longer follow-ups are necessary.

Examination of Various Abutment Designs Behavior Depending on Load Using Finite Element Analysis

Biomimetics, Journal Year: 2024, Volume and Issue: 9(8), P. 498 - 498

Published: Aug. 16, 2024

Studies on dental implant abutments’ geometric design and material selection offer significant innovations results. These studies aim to improve the functionality aesthetic performance, minimize microcavities’ formation, ensure implant-supported prostheses’ longevity. For example, CAD-CAM fabricated custom abutments have been found produce a better marginal fit fewer microgaps than standard abutments. In an in vitro study, transepithelial offered lower microgap values titanium-based provided at implant–abutment interface. It is known that mechanical biological performance with Polyether Ether Ketone (PEEK) addressed. New materials such as PEEK zirconia advantages biocompatibility aesthetics. Along those studies, different abutment designs are also important. Abutment geometry optimized stress distribution peri-implant bone loss. connections angles, life performances may vary depending static dynamic load. emphasize importance of research types implants’ durability, homogeneous load distribution, reliability.

Internal adaptation assessment of implant infrastructures manufactured through five different techniques (heat-press, milling, lost wax, calcinable cylinder, and CAD/Waxx®): an in vitro pilot study

Frontiers in Dental Medicine, Journal Year: 2024, Volume and Issue: 5

Published: Nov. 6, 2024

The aim of this study was to evaluate the fit performance implant infrastructures manufactured by five different techniques: heat-press (IPS), milling (ZIR), lost wax (CER), calcinable cylinder (CAL), and CAD/Waxx® (CAD). methodology based on Replica Technique, which can simulate infrastructure component. Thus, each internally filled with low-viscosity silicone addition seated component until its final setting, obtaining replica cementation space. After removing coping containing film, light-density inserted in place components, surroundings, condensation applied, establishing support for assembly. joint sectioned mesiodistally, photographed, analyzed image processing software order measure thickness interface infrastructure/implant at areas: marginal opening (M), gingival-axial angle (G-A), axial region (A), axial-occlusal (A-O) occlusal surface (O). lowest highest average between groups was, respectively, IPS: 187.5 μm CAD: 221.6 μm, statistically significant differences (p < 0.01) among all groups; point A: 99.86 O: 279.78 μm. IPS group exhibited value internal space implant. demonstrated a correlation findings literature, except CAL group; otherwise, angles A-O G-A values beyond that expected. It possible conclude presented adaptations, suggesting interference spaces due manufacturing processes.
