1. dental IMPLANTs

2. WHY IMPLANTS??

3. IMPLANTATION : INSERTION OF ANY OBJECT OR A MATERIAL, WHICH IS ALLOPLASTIC IN NATURE EITHER PARTIALLY OR COMPLETELY INTO THE BODY FOR THERAPEUTIC, EXPERIMENTAL , DIAGNOSTIC OR PROSTHETIC PURPOSE

4. Knowledge ? HOW TO START PRACTICE ? POINTS TO BE KNOWN ? WHAT NEEDS TO BE CONSIDERED? BASIC ARMAMENTARIUM NEEDED ? WHEN TO TAKE HELP ?

5. Types of implants

6. (B) SHAPE: Screw type implants Cylindrical, apically tapered, and fully tapered Platform-switch implants Bone level vs. tissue level implants (C) IMPLANT SURFACE Machined ( Brånemark surface) Textured/rough surfaces Hydrophobic/Hydrophilic surfaces (D) IMPLANT LENGTH (E) IMPLANT DIAMETER (A) IMPLANT MATERIAL Titanium and titanium alloys Zirconia IMPLANTS CAN BE CLASSIFIED AS FOLLOWS

7. Parts of implant

8. SUCCESS CRITERIA BASIC GUIDE TO OSTEOINTEGRATION BIOCOMPATIBILITY AND IMPLANT DESIGN BONE FACTORS LOADING CONDITIONS PROSTHETICS CONSIDERATION

9. OSSEOINTEGRATION : THE APPARENT DIRECT ATTACHMENT OR CONNECTION OF OSSEOUS TISSUE TO AN INERT, ALLOPLASTIC MATERIAL WITHOUT INTERVENING CONNECTIVE TISSUE

10. IMPLANT ABUTMENT : COMPONENT ATTACHES TO IMPLANT AND SUPPORTS THE PROSTHESIS TMA OR TRANSMUCOSAL ABUTMENT :- PASSES THROUGH MUCOSA OVERLYING IMPLANT TEMPORARY OR HEALING ABUTMENT :- USED DURING HEALING PHASE BEFORE DEFINITIVE TREATMENT

11. COVER SCREW / HEALING CAP : USED IN TWO STAGE IMPLANT GINGIVAL FORMER:

12. SINGLE Stage IMPLANT SURGICAL PLACEMENT OF IMPLANT WHICH IS LEFT EXPOSED TO THE ORAL CAVITY FOLLOWING INSERTION USED IN NON-SUBMERGED IMPLANT SYSTEMS

13. TWO STAGE IMPLANT INITIAL SURGICAL PLACEMENT OF A DENTAL IMPLANT WHICH IS BURIED BENEATH THE MUCOSA AND THEN SUBSEQUENTLY EXPOSED WITH A SECOND SURGICAL PROCEDURE MONTHS LATER USED IN SUBMERGED IMPLANT SYSTEM

17. planning Techniques used to plan implants To help the surgeon position the implants a guide is made (usually out of acrylic) to show the desired position and angulation of the implants.

18. Radiographic Examination Evaluation phase to determine the status and anatomy of the underlying bone The radiograph of choice is the Cone Beam Computerized Tomography (CBCT) as it provides a detailed three-dimensional analysis P ossible to measure accurately the dimension of the site and distances from critical structures and accurately plan which implant dimension would be appropriate

19. Three-dimensional imaging data is used to plan the surgical guide

20. A 2-dimensional radiograph of the area is desired ; though it is insufficient to provide 3 dimensional details -Measure accurately the dimension of the site and distances from critical structures and accurately plan which implant dimension would be appropriate

21. Correct 3-Dimensional Position for an Implant T he available space should be evaluated in three dimensions E valuating factors such as proximity to adjacent anatomical structures such as maxillary sinus, mandibular nerve, nasal floor, adjacent tooth roots, etc. should be considered A 2mm safe distance should be maintained from all vital structures

22. The ideal mesiodistal distance between a natural tooth and the shoulder of an implant is 1.5 mm The zone up to 1–1.5 mm from the adjacent teeth on either side was the danger zone Between the danger zone was the comfort zone that is safe for implant placement

23. Ridge maping caliper . • Used as measuring instruments in preparationfor an implant procedure • Designed to find the depth, width and space between teeth which may be required for various dental procedures CALIPERS

24. BARD BARKER BLADES Blade No.10- similar to No.15 Large skin incisions Blade no. 11 is used for small incisions , such as those used for incising abscesses (stab incision) Blade no. 12 is indicated for incisions in inaccessible areas such as the maxillary tuberosity & retromolar areas. Blade is no. 15 The most common type used for flaps and incisions on edentulous alveolar ridges.

25. Mouth props: Rubber bite blocks used to hold the mouth open. Use: retraction of flaps or cheek RETRACTOR

27. Concept of Timing for Implant Placement Type 1 : When placed immediately after tooth extraction, it is called immediate implant placement. Type 2 : When placed 4–8 weeks after tooth extraction, it is an early implant placement with only soft tissue healing Type 3 : When placed 12–16 weeks after tooth extraction, it is an early implant healing with partial bone healing Type 4 : When placed after 6 months after tooth extraction, there is complete bone healing, and this is called delayed implant placement.

28. INDICATIONS SINGLE UNIT TOOTHLESS GAP WITH HEALTY ADJACENT TEETH PARTIAL EDENTULISM WITH POSTERIOR TOOTH MISSING COMPLETE EDENTULISM SITUATIONS WHERE : PATIENTS CANNOT TOLERATE REMOVABLE RESTORATION , PATIENTS WITH HIGH AESTHETICS DEMAND

29. CONTRAINDICATIONS UNCONTROLLED DIABETES ANGINA PECTORIS CERTAIN AUTO IMMUNE DISEASES DRUG AND ALCOHOL DEPENDENCY PREGNANCY CHRONIC SMOKERS ABNORMAL POSITION OF VITAL STRUCTURES HYPERSENSITIVITY OR ALLERGIC REACTIONS
