Dental implants

  1. 1. Presentation by : Huma Javeriya Guided by Dr Tanveer mam. Dental Implants
  2. 2. 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”
  3. 3. Types
  4. 4. Others gold tantalumandcarbon MATERIALS USED POLYMERS AND COMPOSITES CERAMICS METALS Metals Stainless steel Cobalt Chromium molybdenum based Titanium and its alloys Surface coated titanium Tantanlum Ceramics Hydroxyapatite Aluminium oxide Polymers andcomposites
  5. 5. 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. FIXTUR E ABUTMEN T
  6. 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. 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. 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
  9. 9. 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
  10. 10. 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
  11. 11. 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.
