Architecture of the bone matrix
It is the scaffold form that allows the bone to withstand the
forces exerted by the implant during its function.

Osseointegration
The term osseointegration is often defined as an internaland stable relation between the anchoring of the implantand formation of bone tissue without the growth of fibroustissue on the bone-implant surface.
This implies that the osteoblast and the mineralized matrix are in contact with the surface, even when oclussal loads are applied.

Osseointegration
It is common in the bone repair process
Osteoconduction: refers to the growth of the bone on a
surface (bone implants).
A titanium oxide surface promotes the deposition of bilogical molecules that enable the existenceof bone near the implant surface.
How does this phenomenon come about?

How long does this process take? We can extrapolate from the bone healing process to
osseointegration with the implant.

that I placed in the most similar parameters possible
over a period of 12 - 18 months.

observe how cancelllous bone tissue is organaized
architecturally (bone matrix) around the implants and compare
this with bone matrix around a natural tooth.

Methodology
1) The study was carried out with more than 100 patients in the 2nd and
3rd stages of life (40 to 60 years) with good health.
2) The indications for each manufacturer were followed.
3) The specific surgical kit for each implant was used.
4) Flap technique was used in the implantation of all implants.
5) Surgery was performed in a sterile surgical environment, in an
operating room.
6) All patients were monitored during the first four weeks of
implantation.
7) Ultra High Definition X-Ray (Vatech iPax) equipment and densities
software (Corel Corporation 2010 – PPX15) was used for this study.
8) The resolution and chromatic filtration for the study were
constant throughout the study, as shown in the table.
9) The results were plotted according to qualitative observation.

Despite the success in current implantology there are
still several problems to be solved:
1. Understanding regeneration around the implant surface.
2. How the different surfaces of the implant help to
accelerate union with the bone.
3. The formation of the bone matrix must correctly
duplicate what is present in natural teeth, thus ensuring
proper support of the masticatory forces by the implant.

Our preliminary conclusions are that for the bone to form correctly and evenly all surfaces of the implant and the formation of the bone matrix must be created with a horizontal trabecular similar to a natural tooth:
1. Contact osteogenesis is the most important phase in the initiation of osseointegration on the implant surface.
2. The implant surface must be homogeneous, free of any impurities or scratches in the manufacturing process. Its architectural design must enable and facilitate the collagen-free hydroxyapatite deposition (cementum) which is the first contact of bone with the implant surface.
3.- During the clinical procedure the physician must work in an environment that is free from dust and micro organisms that can contaminate the implant surface.
4. The cleanliness, purity and homogeneity of the implant surface is critical.
5. The surface roughness (rugosity) has a definitive influence on the bone matrix formation.

It is critical to place dental implants
in a surgical environment, or as
clean as possible.

The most common bacteria in a dental clinic:
Streptococcus
The control of
infections in
the area where
dental implants
will be placed
is the
responsibility
of the
implantologist.
