“…Researches have challenged several aspects of this specific protocol, and their investigations found the relative importance of helix design on osseointegration. Therefore, the identification of guidelines for the long-term success (i.e., total implants still in place at the end of the follow-up, good clinical, radiologic, and aesthetic outcome) has been to achieve good clinical outcome (17)(18)(19)(20). Many variables may influence the clinical outcome of SDI: surgery protocol, bone quality and quantity, helix design, and occlusion (21)(22)(23)(24)(25).…”

SUMMARYSpiral dental implant (SDI) is an implant with a conical internal helix that confers the characteristic of self-drilling, self-tapping, and self-bone condensing. These proprieties offer better control during insertion of SDI giving a high primary stabilization, even in poor quality bone. A shorter diameter of SDI results in reduced drilling during insertion and consequently less trauma and minimal bone loss. To address the research purpose, the investigators designed a retrospective cohort study. The study population was composed of 25 patients, 11 males and 14 females that have been treated by Dr. Balan with 187 SDI positioned in mandible and into maxilla bone. The implants were placed during the years 2013 to 2014 in Dr. Balan clinic. All patients underwent the same surgical protocol. Several variables are investigated: demographic (age and gender), anatomic (upper/lower jaws and tooth site), implant (length and diameter and type) variables, edentulism (partial or total), and comorbid status of health (i.e.: hypothyroidism, parodontitis, hypertension, diabetes, presence of cancer, heart disease, hepatitis and rheumatologic disease). Pearson Chi-Square test was used to investigate variables and p < 0.05 was considered statistically significant. Statistically it has been shown that females have a higher possibility of unsuccessful respect of male, with a "p value" of 0.014. Another important impact factor for success of implant insertion has been represented by concomitants pathologies: cancer represents the most negative high factor risk with a percentage of unsuccessful of 50%, followed by heart disease (15%), and diabetes (3.7%). SDIs are reliable tools for difficult cases of oral rehabilitation. They have a higher success and survival rate, which means stable results over time. No differences were detected among SDI lengths, implant/crown ratio. In addition, the insertion of SDIs in banked bone can be performed without adverse effects. Finally, flapless and computer tomography-planned surgery does not significantly increase the clinical outcome of SDIs in complex rehabilitation. Cancer represents the most important variable to consider when a patient wants to do oral rehabilitation because of its high risk of unsuccessful.

“…This type of implant produces increased residual crestal bone volume and carries several advantages like reduced stress and repositioning of gingival papillae. 2 Ericsson et al indicated that the bone is always encircled by approximately 1 mm of healthy connective tissue, so it can be assumed that crestal bone remodeling takes place to create space between the bone and inflammatory cell tissue (ICT) to establish a biologic seal. PLS refers to the use of a smaller diameter abutment on a larger diameter implant collar.…”

New implant designs have appeared in the literature which claim that certain modifications may be helpful for maintaining crestal bone levels and consequently preserving normal soft tissue contours. Maintenance of soft tissue has been shown to depend on preservation of bone surrounding the implant. In order to achieve this goal, each step of the treatment must be managed carefully. This requires knowledge of pre-surgical treatment planning, site development, implant positioning, soft tissue management, provisionalization and prosthetic management.Placement of a smaller diameter abutment on a large diameter implant platform (platform switching) has been proposed as an effective way to control circumferential bone loss around dental implants. The purpose of this paper is to evaluate the literature from an evidence based point of view regarding implant design modifications for preserving soft and hard tissue around implants.

“…This type of connection moves the perimeter of implant abutment junction (IAJ) to the center of implant axis. It is possible that moving the (IAJ) inward brings out bacteria more internally and, therefore, away from the bone crest; this would explain the limitation in bone resorption 9,10 . According to Carinci et al 11 platform switching can be achieved by using abutments with a diameter smaller than the implant neck or body width, by increasing the implant neck diameter with respect to the implant body width, using platform-switched implants and conical emergence abutments and finally using implants with a reverse conical neck referred to as Bone Platform Switching. This embraces an inward bone ring in the coronal part of the implant that is in continuity with the alveolar bone crest.…”

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.
