“…With regard to the included articles that analyzed vertical bone resorption with periapical radiographs, the analysis shows that in two studies out of three (Sesma, 2016 andCassetta, 2016), which analyze the platform switching connection, there is a reduction in peri-implant bone resorption. Sesma et al, recorded a vertical bone change equal to 0.40 ± 0.19 one year after functional loading, while in the study by Cassetta et al, the mean marginal bone remodeling was −0.56 mm.…”

“…Clinicians must keep in mind that peri-implant bone resorption is a multifactorial problem and other factors should be always analyzed: implant collar design, apico-coronal implant location, and soft tissue thickness. Special attention to the soft tissue thickness indicated a potentially key role in preventing peri-implant bone resorption: it was found that thin soft tissues (<2 mm) may prove peri-implant problems, despite the advised use of platform switching [10,11,[36][37][38].…”

The Impact of Implant–Abutment Connection on Clinical Outcomes and Microbial Colonization: A Narrative Review

Introduction: Osseointegration are often suffering from oral conditions, especially, the micro gap at the implant–abutment connection represents a site for bacterial plaque aggregation, leading to increased inflammatory cells and causing peri-implantitis. Aim: The aim of this narrative review was to describe the different kinds of implant–abutment connections and their ability to reduce bacterial leakage and thus prevent peri-implantitis. Materials and methods: The following databases were consulted: Pubmed, Scopus, Cochrane Library, and Research gate and a total of 528 articles were found. After reading the abstract and titles, 473 items were excluded. The remaining articles (n = 55) were assessed for full-text eligibility. Thirty-three studies were included in the review. Results and Conclusions: We selected 22 clinical trials and 11 reviews, examining a total sample of 2110 implants. From the review, it was clear that there exists a relationship between the implant–abutment interface and bacterial leakage. All the connections presented an amount of micro-gap and bacterial micro-leakage, though conical and mixed connection systems seemed to behave better. Moreover, both connections seemed to have a better load distribution and the mixed system also had anti-rotational properties which are very useful during the positioning of the prosthesis.

Immunological and inflammatory mechanisms perform a key role in the development and progression of type 2 diabetes mellitus. The objective of this study was to evaluate immunologically the effect of different implant abutment interface, the platform switched (PS) and platform matched (PM) implants for implant assisted complete mandibular overdenture in controlled type II diabetic patients. Methodology: Ten edentulous controlled type II diabetic male patients were selected in a split-mouth study design, where group I represented the right side of the patient and restored with platform-switched implant while group II represented the left side of the patient and restored with platform matched implants. The patients received complete mandibular implant assisted overdenture with O-ring attachment. Saliva samples were collected to measure the level of salivary cytokines (TNF-α & IL-6) using ELISA technique. The recall visits for every patient was at the time of insertion, 3 and 6 months. The data of this study were collected, tabulated and statistically analyzed by IBM-SPSS statistics software. Results: Comparing from denture insertion for group 1, both cytokines (TNF-α & IL-6) were significantly increased after 3 months and significantly decreased after six months, but there were insignificant differences in both cytokines from denture insertion up to 6 months. While for group 2, there a was significant increase from 0 to 3 months and from 0 to 6 months and significant decrease from 3 to 6 months. When comparing the two studied groups regarding the mean level of both pro inflammatory salivary cytokines (TNF-α& IL-6) after 3 and six months of the new denture delivery, group II levels were significantly higher than group I levels. There were significant differences between both groups. Group I implants represented less mean of TNF-α & IL-6 levels. Conclusion: TNF-α and IL-6 can be used as a site specific marker in monitoring early inflammatory changes in peri-implant sulcular fluid. Platform-Switched dental implant is the implant of choice particularly in controlled type II diabetic patients to control inflammatory changes around implant and avoid progression of type 2 diabetes mellitus.

“…Studies have shown that bacterial contamination of the microcracks between the implant and the abutment adversely affects the stability of the peri-implant tissues. (7)(8)(9) In an attempt to improve long-term bone maintenance around implants, implant-to abutment connection referred to as "platform switching" has been proposed. It refers to the use of an abutment of smaller diameter connected to implant neck of larger diameter.…”

Twenty completely edentulous patients with age ranged between 50 and 60 years were selected for this study. Complete dentures were constructed for all patients. The patients were divided into two groups; ten patients each. The first group was received two platform switched implants (3.6 × 11.5 mm) in the canine regions of the mandible. The second group was received two platform matched implants (3.6 × 11.5 mm) in the canine regions of the mandible according to two stage surgical protocol. Radiographic and clinical evaluations were performed throughout the twelve months follow up. The result of the study revealed that there were no statistically significant differences in marginal bone loss between mandibular overdentures retained by two platform switched implants and that retained by two platform matched implants. Also, there were no statistically significant differences in pocket depth or implant mobility between two studied groups. This study concluded that platform switching didn't influence marginal bone loss around implants or soft tissue supporting mandibular overdenture dentures.
