Definition:
• An oral or dental implant is a biologic or
alloplastic biomaterial surgically inserted
into soft or hard tissues of the mouth for
functional or esthetic purposes.

Historical perspective:
• The earliest implants - Stone and Ivory
• 16th and 17th centuries- Gold and Ivory
• Early 20th century-
Gold,Lead,Iridium,Tantalum,S.S and
Cobalt
• 1940-Cobalt chromium Molybdenum
• 1960-Titanium blade and sub-periosteal
• 1982- Osseo-integrated Implantswww.indiandentalacademy.com

Types of implants:
• Sub-periosteal implants
• One stage-endosteal pins ,screws and
cylinders
• Blade implants
• Transosteal implants
• Endosteal root form implants

Resorption pattern-
Residual ridges
• MECHANICAL
• BIOLOGIC
• ANATOMICAL

Patterns of resorption:
• GENERAL CHANGES
• MAXILLARY CHANGES
• INTER-MAXILLARY RELATIONSHIP
CHANGES
• SOFT TISSUE CHANGES

Anatomic considerations:
• MANDIBLE-
> Body region
> inferior alveolar nerve location
> Symphysis region
• MAXILLA-
> Alveolar arch morphology
> Maxillary sinus
> Mucosal tissues.www.indiandentalacademy.com

Healing of Endosseous Implants:
• Inflammation
• Proliferation
• Maturation
• Bone healing

Factors affeting healing:
• Surgical technique
• Treatment protocol
• Patient selection
• Oral hygiene
• Loading pattern
• Site selection
• Surgical fit
• Bone qualitywww.indiandentalacademy.com

Biocompatibility,Biofunctionality
and Biomechanics of implants:
• Implant material should have suitable mech
anical strengh,biocompatablity and
structural biostability in physiologic
environments.
• Biologic classification: Biotolerant ,
• Bioinert&Bioactive

Tissue response to implant
materials
• Titanium&titanium based alloy
• Surface active ceramics
• Cobalt chrome molybdenum

Implant fixation methods:
• Direct bone growth into the implant surface.
• Bone growth into porous surfaced implants.
• Chemical bonding between bone & surface
active chemical implant coatings.

IMPLANTS IN
ORTHODONTICS:
• Anchorage control.
• Guide to orthopedic development
• Onplant:it is not embedded in to bone but
becomes biointegrated onto the surface of
the bone.Developed by BLOC
&HOFFMAN to act as a sub periosteal
orthodontic anchor.

Osseointegrated Implants for
orthodontic anchorage.
• Titanium endosseous implants used.
• ETA Exacta is a dental root form implant
made of pure titanium.It has an acrylic
abutment that can be adapted to an
orthodontic band or temporary crown.
• Disadvantages: Cost of surgical procedure.
• The implant healing time.

Implant as an anchorage for
molar uprighting and intrusion.
• An intrusive force on the molar can only
occur when an extrusive force is placed else
where.Ankylosed teeth &dental implants
provide ideal anchorage because they are
incapable of moving with in the bone.

Mesial transalation of mandibular
molars:
• Retro molar dental implants served as
anchorage to close first molar extraction
sites.
• Orthodontic transalation is a physiological
manifestation of bone modeling &
remodeling through out the adjascent
alveolar process &rate of molar transalation
is inversly related to the radiographic
density of the resisting alveolar bone.www.indiandentalacademy.com

Implants as skeletal anchorage:
• With screw, pins or some other readily
removable implant anchored to the jaws
forces might be applied to produce tooth
movement in any direction with out
detrimental reciprocal forces.
• Orthopaedic forces might be applied
directly to the jaws through skeletal
anchorage.

Implant used as anchorage to
protract molars and close an
atrophic extraction site:
• A two stage endosseous implant,placed in
the retromolar areas of the mandible was
used as anchorage.
• Micro radiographic &polarised light
analyses reveled that about 80% of the
endosseous portion of the implant was in
direct contact with mature lamellar bone.

Implants: Periodontic
&Prosthodontic consideration of
Niti-SE steel uprighting springs.
• This uprighting spring is an effective
method to upright molars with out
periodontal &gnathological problems
provided adequate anchorage is available.
• Pseudo elastic areas transfers constant
moment&forces to the molars.Intrusive
forces can be applied by bending&
adjusting the steel part.

ORTHOSYSTEM - implants for
Orthodontics
• Orthosystem Implants measuring 4 mm and
6 mm in height with a diameter of 3.3mm
were placed in the median palatal suture
• Transpalatal bar was bonded on the
posterior teeth and fixed to the implant
• orthosystem implant is a easy procedure
that can be performed by an orthodontist
when maximal anchorage is required

TIMING OF ORTHODONTIC
AND IMPLANT TREATMENT
• In growing patient`s orthodontic treatment
was done first while the implant was placed
at the end of the pubertal growth and
development
• In border line cases a slight modification of
the implant position relative to the
surrounding tooth was performed
• Orthodontic treatment was performed after
the evaluation of bone spacewww.indiandentalacademy.com

CONCLUSION
• Eventhough implants has a wide array of
usage in orthodontic practice, small set
backs like economy, technique
sensitivity,operator skill,and patient`s
co-operation do pose a problem in routine
practices.
