Clinical Trial Summary

In this controlled clinical study, a maxillary sinus lift (crestal approach) with OSSIX® Bone will be performed, and then implants MultiNeO CS (control group) and NINA MultiNeO NH (test group) will be inserted in edentulous posterior maxillae of study subjects. .+the clinical and radiographic results of the rehabilitation of posterior edentulous maxillary areas, obtained with traditional surface implants (MultiNeO CS, control group), are compared with those obtained with bioactive surface implants (NINA - MultiNeO NH, test group ).

Description:

In this post- market controlled clinical study, the tested CE-marked dental implants are MultiNeO CS 1930 and NINA MultiNeO NH 9330, both manufactured by Alpha-Bio Tec. 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 to treat control group. One of the MultiNeO CS biggest clinical advantages since it is as good at bone type 4 as it is at bone type 1, 2 or 3.

MultiNeO CS has an implant surface with a sub-micron scale roughness created by Aluminum oxide blasting and double acid etching.

NINA MultiNeO NH is used for tret group, it 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 Patient requiring sinus floor elevation with native bone crest height > 4 mm will be enrolled.Although a variety of implant surface are available for implant supported rehabilitation, the first hypothesis is that NINA MultiNeO NH Alpha-Bio Tec will be present faster osteointegration time compared to MultiNeO CS when adopted to rehabilitate of missing teeth in case of critical areas such as in the posterior mandible with critical bone defects. The second hypothesis is that NINA MultiNeO NH will promote a better apical bone regeneration in patients treated with sinus lift compared to MultiNeO CS due to its bioactive surface.

Primary	Implant stability	check implant stability using resonant frequency analysis (RFA) Resonance frequency analysis (RFA) provides objective measurements of implant stability in a non-invasive way on the bone-implant interface. The results of the resonance frequency analysis are transformed into implant stability quotient (ISQ) values. ISQ, implant stability quotient, depends on the transducer used and is recorded as a number between 1 and 100, 100 representing the highest degree of stability. Transducers are designed for specific implant types and calibrated by the manufacturer.	immediately after implant placement
