Does Implant-Abutment Interface affect Marginal Bone Levels around Implants?

Abstract

Objective The use of dental implants with different types of surface roughness and implant-abutment interface has brought about a situation of marginal bone loss. Therefore, the aim of this study was to analyze and compare marginal bone levels of different types of osseointegrated dental implants with platform switch (Group A: Ankylos, Mannheim, Germany) and platform match (Group B: Dentsply Xive, Mannheim, Germany, and Group C: MIS Implant Technologies, Karmiel, Israel). Materials and Methods One hundred and seven patients (52 men and 55 women) with a mean age of 54.79 (standard deviation ± 12.35) years and a total of 321 dental implants (Group A, n = 198; Group B, n = 58; and Group C, n = 65) placed in a private practice between April 2006 and May 2015 were retrospectively analyzed. In addition to demographic information and implant characteristics, marginal bone levels were evaluated by Image J (Wayne Rasband, National Institute of Health, Maryland) program. Results The mean age of all patients was 54.79 ± 12.35 years, and 51.5% of them were women. Implants supporting fixed bridge were most commonly used in all groups (65%), whereas only 20% were restored with a single crown and 15% with overdentures. In total, 47.5% of all implants showed no marginal bone loss. Mean bone loss in Group A was significantly lower (0.81 ± 1.60 mm) as compared to Group B (1.58 ± 1.59 mm) and Group C (1.18 ± 1.36) (p < 0.005). Conclusion Among different types of dental implants, platform switch seems to preserve marginal bone levels and increase the long-term success of dental implants.

Bone remodeling around dental implants after 1–1.5 years of functional loading: A retrospective analysis of two‐stage implants

“…In the present study, bone‐level implants were used with a platform switching design. Platform switching helps minimize crestal bone remodeling and preserves the marginal bone level around the implants (Elemek et al, 2019 ; Hürzeler et al, 2007 ; Lazzara & Porter, 2006 ; Messias et al, 2019 ). However, platform switching on implants can lead to a higher emergence angle, increasing the chance of bone level alterations (Dixon & London, 2019 ).…”

High-Flux Direct-Contact Pervaporation Membranes for Desalination

“…In a typical process, the shadow of the perforated part could be obtained by adjusting the image to grayscale. The software could calculate the percentage of the shadow area in the overall effective area of the image (that is, the porosity) and estimated the average pore sizes of the shadow parts. − …”

Micro Computed Tomography and Immunohistochemistry Analysis of Dental Implant Osseointegration in Animal Experimental Model: A Scoping Review

“…1,2 Osseointegration aims to maximize the implant-tobone contact while lowering failures. 3,4 To further understand the mechanism, in vivo studies have been used to conduct preclinical testing, but there are debatable subjects such as which animal models (large animal or rodent) could strongly correlate with clinical outcomes, particularly relevant to human maxillofacial intramembranous ossification and accommodating the biomechanical properties (size, design, topography, and drilling site) of the implant. 5 Micro-CT allows comprehensive examination of threedimensional microstructures of a bone in tiny samples.…”
