Clinical Trial Summary

In this case-control study a bioactive implant surface was compared with traditional surfaced implants. Primary objectives: Test the implant stability in post-extractive sites, comparing traditional surfaced implants (MultiNeO CS, control group) to bioactive surfaced implants (NINA- MultiNeO NH, treatment group). Primary outcome endpoints were Implant stability, assessed through Implant stability quotient (ISQ) values and Marginal bone loss (MBL)

Description:

In this post- market case control study, the tested CE-marked dental implants are MultiNeO CS 1930 and NINA MultiNeO NH 9330, both manufactured by Alpha-Bio Tec. . Alpha-Bio Tec. implants systems are made of Ti-6AI-4V ELI Titanium alloy which is a high-performance and highly biocompatible alloy for manufacturing bone implants. Alpha-Bio Tec developed the superior NanoTec&trade implant surface for optimized osseointegration process. Alpha-Bio Tec NanoTec™ implant surface is achieved by a complex process of large particle sandblasting and acid etching. Sandblasting with large particles allows the creation of macropores (20-40 microns), while the double etching allows the creation of micropores (1-5 microns). The micro - structure and roughness properties of NanoTec™ Implant Surface greatly influences the dynamic wettability of implant surfaces during the initial contact with the host. The overwritten implant surface enables greater absorption of blood and plasma proteins directly inside the micropores, immediately after the implant has been placed. It is the implant surface of MultiNeO. NeO or MultiNeO is defined as a system since it includes three types of connections: a conical narrow connection (CHC), a conical standard conical connection (CS) and an Internal Hex connection (IH). the fixture has a straight coronal part, a slightly tapered body and a conical apical part. We will use MultiNeO CS in control group. One of the MultiNeO biggest clinical advantages since it is as good at bone type 4 as it is at bone type 1, 2 or 3. Topography and surface roughness of MultiNeO lead to some clinical advantages: Increased early BIC; Increased primary and secondary stability; Shortened healing period; Accelerated and improved osseointegration process. MultiNeO CS has an implant surface similar to the aforementioned SLA surface manufactured by Straumann. In fact, SLA is a sub-micron scale roughness created by Aluminum oxide blasting and double acid etching. NINA- MultiNeO NH is used for treatment group, and it is being tested. NINA MultiNeO NH has got an innovative bioactive surface. NINA MultiNeO NH surface is a combination of the abovementioned roughening process and the creation of titanium oxide nano structure. Its hydrophilic part is created by resorbable salt thus maintaining its hydrophilicity. Although a variety of implant surface are available for implant rehabilitation, the first hypothesis is that NINA MultiNeO NH Alpha-Bio Tec ® will be positively adopted for rehabilitation of missing teeth with shorter healing time and less marginal bone loss. The idea behind these studies is to maximize the effect of the bioactive surface testing its behavior in a poor host environment with a reduced time
