Dental implants are materials placed in the jawbone to support dental prosthetics like crowns and bridges. There are two main parts: the fixture embedded in bone, and the abutment that supports the crown. Implants can be one-piece or two-piece designs. Common materials include metals like titanium alloys, ceramics like hydroxyapatite, and polymers. Implants osseointegrate with bone through a process called biointegration, forming a direct connection without soft tissue. Zirconia implants are also used for their aesthetic and biocompatible properties. Dental implants can replace missing teeth and their advantages include immediate function and bone preservation.

2. A Dental implant is a material or device
placed in/on oral tissues to support an oral
prosthesis

Also defined as “ A substance that is placed into the
jaw to support a crown or fixed or removable
denture”

 Basic implant design based on
endosseous design.
 Fixture embedded in bone
 Abutment supports the crown
 The implant may be
 One piece implant and abutment are joined together
 Two piece implant and abutment are separate. The abutment is
secured to the implant by means of an abutment screw.

6. Implant fixture
• Over the years various implant designs have been developed and used. Currently, the
most favoured form is the cylindrical screw or the tapered screw.
• The implant is inserted through a surgical procedure.
• The abutment is usually screwed on to the implant on a later date
• The crown is then constructed and either screwed or cemented on to he abutment
thus completing the restoration

7. Implant abutment
• Is that portion of a dental implant the serves to support and / or retain any fixed or
removable dental prosthesis
Classification
• A. according to fabrication procedure
1. stock abutment 2. Custom 3. CAD/CAM
b. According to material used
1. Titanium 2. zirconia 3. gold 4. steel
C. according to angulation
1.angled 2. non angled

8. Implant abutment connection
• It is one of the factor which helps in proper functioning, stability and longevity of
implant.
• During occlusal function considerable stress may b transferred to the screw and can
lead to its early loosening or even fracture.
• Function. The implant or abutment interface determines joint strength, stability. It
also reduces stress on the abutment screw
• Types of IAC
• External
• internal

10. BIOINTERGRATION AND
OSSEOINTIGRATIONDefined as an apparent direct connection of an implant surface and host bone
without intervening connective tissues
Factors
1. Proper treatment planning
2. Atraumatic drilling of bone
3. selection of proper implant material
4. Implant design
5. Bone quality
6. Good oral hygiene
7. No contraindicating local or systemic factor
8. favourable Occlusal forces

11. Zirconia implants
• Its high strength facture toughness and white colour makes zirconia an
interesting material for the dental implants abutment and superstructure
in anterior zone
• Indications for
• Aesthetic considerations
• Allergy to titanium

12. Advantages
 Aesthetic
 Biocompatible
 Immediate placement
 No additional drilling or surgery required
 No complications of implant surgery
 Shorter waiting period
 Fits into original socket
 Immediate placement for bone and tissues
 Sinus lift not required
 Little or no swelling or pain
 Bone grafting not required
 Faster recovery time.

significant dental innovation of our generation…!!
