A Histomorphometric Study in Rabbits

Merav Folkman, Alina Becker, Isabelle Meinster, Mahmoud Masri, Zeev Ormianer

USING Cortex MAGIX® Drill-Less implant is successful as any other heavy drilling implants.
The dentist and the patients win!! Less chair time, Less risk, Less Side Effects, Less dental implant pain!!
Various factors influence the long-term prognosis of dental implants and can affect osseointegration, such as
surgical technique, host bed, implant surface, implant design, material biocompatibility, and loading conditions.
The objective of this in vivo animal model study was to measure and compare BIC and BV values of a new implant
using 2 different preparation protocols (no site preparation and prior limited cortical perforation), and the values of a
conventional implant using a control protocol (conventional drilling technique).
A test implant with a new thread design- Magix®, Cortex, Israel was inserted using no bone preparation (NP)
and cortical perforation (CP) into 13 New Zealand rabbits.
The study proved that the Magix® implant which enables a prepress insertion provides better primary stability, ridge expansion, and bone preservation, achieving the required osteointegration in terms of BIC and BV.

Immediate post extraction Implant Placement with Immediate PMMA Provisionalization in Sjogren Syndrome Adult Female

By Dr. Ayman K. Zaghal

Sjogren’s Syndrome (SS) is a chronic autoimmune disease that affects salivation and consequently the health of oral tissues at incidence of 0.2 % of the population, a systemic review gave an average of 93.7% survival of implants in such patient’s group and they are good candidate for implants as they can’t wear dentures owning to the lack of saliva and sensitive mucosa.

A New Implant Design for Enhanced Stability In Extraction Site

Dr. Mahesh Chauhan

As patients identify the dentist as the one who extracts teeth, its time to identify ourselves as the ones who replace teeth immediately or at least who fill the socket immediately. The answer comes to us in the form of a winged/ringed Dental Implant called Saturn by Cortex.

J. W. Goethe-University Frankfurt am Main

Director: Prof. Dr. H.-Ch. Lauer

According to this thorough test and its outstanding results, it is well proven that Cortex Implants featuring Conical Connection interface, shows no relevant Micro-Gap nor Micro-Pump-Effect in the Implant-Abutment interface comparing to other leading dental implant brands.

Effect of temperature on the dental implant osseointegration development in low-density bone: an in vivo histological evaluation

Trisi P1, Berardini M, Falco A, Vulpiani MP.

OBJECTIVES:

To make an in vivo evaluation of the effects of 2 different bone temperatures, on the development of implant osseointegration, in low-density bone.

MATERIALS AND METHODS:

Fifteen implant osteotomic sites were prepared in the iliac crests of sheep. Before the implant insertion, 5 sites were heated to 50°C for 1 minute, 5 sites to 60°C for 1 minute, and 5 sites were not overheated. Fifteen titanium dental implants (Cortex) were inserted. After a healing period of 2 months, the histomorphometric parameters calculated for each implant were the Bone-Implant Contact percentage (%BIC) and the infrabony pocket depth. Unpaired t test was applied to find statistical differences between groups.

Influence of minimally invasive implant-retained overdenture on patients’ quality of life: a randomized clinical trial

Jorge Jofre, Ximena Castiglioni, Claudia Asenjo Lobos

Objectives: The aim of this prospective, randomized clinical trial was to evaluate the effect of aminimally invasive implant procedure for denture stabilization on patients’ quality of life (QoL).Materials and methods: Thirty totally edentulous patients were selected for this study. Allprostheses were adjusted and relined before randomization and allocation to treatment eitherwith two small diameter implants (SDI) – retained overdenture (study group) or non-interventiongroup (control group). Quality of life was assessed using the Oral Health Impact Profile-EDENT(OHIP-EDENT) questionnaire before intervention and at one-year follow-up. Between-groupcomparisons were carried out using the non-parametric Mann-Whitney test.Results: Magnitude of change in the OHIP-EDENT total score at one-year follow-up was25.4 ± 10.7 for the study group, revealing a statistically significant difference with the controlgroup, that showed a change of 9.5 ± 8.3 (P = < 0.001).Conclusions: After one-year follow-up, patients wearing mandibular overdentures with twominimally invasive splinted SDI, experienced more improvements in perceived oral health-relatedquality of life, than patients having conventional treatment.

New-Design Dental Implants: A 1-Year Retrospective Clinical Study of 344 Consecutively Placed Implants Comparing Immediate Loading Vs. Delayed Loading and Flapless Vs. Full -Thickness Flap

Replacement of missing teeth with affordable dental implants has become widely accepted.In the last 25 years, typical dental treatment involving dental implants is carried out in two stages. The implant is inserted into the bone during the first stage, and then left for 3-6 months without loading, for the healing process to take place. The second stage involves exposing the implant, and loading prosthesis. The load-free healing period was considered to be important to provide time for formation of a direct interface between the dental implant and bone, without intervening soft tissue. This term is often referred to as osseointegration and is thought to minimize the risk of implant failure.

Effect of 50 to 60°C Heating on Osseointegration of Dental Implants in Dense Bone: An In Vivo Histological Study

Trisi, Paolo DDS, PhD | Berardini, Marco DDS | Falco, Antonello DDS, PhD | Vulpiani, Michele Podaliri VMD | Masciotra, Loredana MD

Objectives:

To evaluate, in vivo, the effects of bone temperatures increased up to 60°C introduced before implant insertion on titanium implant osseointegration.

Aesthetic rehabilitation using a special implant design

Dr. Franck Lasry, DDS

Immediate implant placement in fresh extraction sockets and immediate loading is now considered to have the same prognosis as the conventional two-step technique. Most issues encountered are due to recession of the alveolar ridge following bone resorption during the first postoperative months. With the exception of problems related to surgical error or infection, the incidence of problems can be reduced by providing good initial stability for the implant within the socket. Aesthetic rehabilita

"SATURN" The Ideal implant for D5 Bone Type

Dr. Zvi Laster D.M.D

Surface roughness is an important factor in early osseointegration (Alberktsson et al).However, it is the macro-architectural design of the implant that establishes initial mechanical stability, which is crucial in minimizing implant mobility in the first 3-4 weeks of function.The Ideal implant for D5 Bone Type

Biomechanics Analysis of a "Wing" Thread SATURN Dental Implant

Prof. Haim Abromovich | Ilan Weissberg

The purpose of this study is to examine the biomechanical advantages of a new implant line development by Cortex Dental called SATURN. The SATURN implant features a specially designed expanded diameter mid-crestal “ring” thread, which provides added bone contact for greater insertion torque achieving primary stability.
The examination was done by using three-dimensional (3D) Finite Element Model (FEM) to evaluate the influence of SATURN implant versus classical cylindrical implant on the stress

The SATURN immediate load post extraction dental implant: a one year pilot study of 140 consecutive implants

Dr. Zvi Laster D.M.D | Sharif Araide, DMD | Aaron Gonshor, DDS | Daniel Baruch, Eng

Dental implants have become a widely accepted treatment option for both partly and fully edentulous patients (1,2). The physiological basis for the success of dental implants lies in the unique bone reaction to titanium and Ti-6A1-4V alloy (3). The term "Osseointegration" relates to the fact that unlike other materials, titanium and titanium alloy allow a direct bone deposition upon the implant surface. This phenomenon allows dental implants to anchor firmly in the alveolar bone;
