- 20. 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.
- 21. 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 • Possible to measure accurately the dimension of the site and distances from critical structures and accurately plan which implant dimension would be appropriate
- 22. THREE-DIMENSIONAL IMAGING DATA IS USED TO PLAN THE SURGICAL GUIDE
- 23. 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
- 24. CORRECT 3-DIMENSIONAL POSITION FOR AN IMPLANT • The available space should be evaluated in three dimensions • Evaluating 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
- 25. 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
- 26. • 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

BARD BARKER BLADES Blade No.10- similar to No.15 oLarge 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.

- 30. 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.

- 32. 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
- 33. An area with a single missing tooth An incision is made across the gingiva, and the flap of tissue is reflected to show the bone of the jaw. Once the bone is exposed, a series of drills create and gradually enlarge a site (called an osteotomy) for the implant to be placed. The implant fixture is turned into the osteotomy. Ideally, it is completely covered by bone and has no movement within the bone. A healing abutment is attached to the implant fixture, and the flap of gingiva is sutured around the healing abutment.
