Dental Implants

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

Definition

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

Types

Endoosseous

Transosteal

Subperiosteal

parts 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.

FIXTURE

ABUTMENT

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

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 procedure1. stock abutment 2. Custom 3. CAD/CAMb. According to material used1. Titanium 2. zirconia 3. gold 4. steel C. according to angulation1.angled 2. non angled

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

BIOINTERGRATION AND OSSEOINTIGRATION

Defined as an apparent direct connection of an implant surface and host bone without intervening connective tissues

Factors1. Proper treatment planning2. Atraumatic drilling of bone3. selection of proper implant material4. Implant design5. Bone quality6. Good oral hygiene7. No contraindicating local or systemic factor8. favourable Occlusal forces

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

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.

Comparison between Normal tooth and Implant

Dental implants are considered as the most

significant dental innovation of our generation…!!
