  3. 3. RATIONALE Replacement / Restoration of lost teeth has post challenges since time immemorial. The needs are different: -Completely edentulous -Partial edentulous -Others www.indiandentalacademy.com
  4. 4. COMPLETE DENTURES Patient Education Common Problems with Dentures: •Inability to speak clearly. •Inability to eat certain foods (salad, steak, corn-on-the-cob). •Fear of social situations. •Use of adhesives. •Interference with taste. •Uncomfortable. © Centerpulse Dental Inc., 4937 rev 04/03 www.indiandentalacademy.com
  5. 5. FIXED PARTIAL DENTURES Patient Education A Traditional Bridge •Damages •Takes neighboring virgin teeth. the underlying bone out of function. •Susceptible to decay around prepared teeth. •Statistically, it needs replacement every 7 to 10 years.

  6. 6. OSSEO INTEGRATION … Is a histologic definition meaning “ a direct connection b/w living bone and load bearing Endo Osseous Implant at the light microscopic level” www.indiandentalacademy.com
  7. 7. Patient Education Dental Implants A dental implant is an artificial tooth root. Implant restorations look and feel more like your natural teeth than other therapies. For those who have removable restorations (full or partial dentures) dental implants increase stability, function, esthetics and preserve the structural integrity of bone. www.indiandentalacademy.com © Centerpulse Dental Inc., 4937 rev 04/03
  8. 8. Patient Education How does bone attach itself to the implant? Just like a rock climber secures his climb by driving his piton deep into rock, an implant attaches to bone. www.indiandentalacademy.com © Centerpulse Dental Inc., 4937 rev 04/03
  9. 9. OSSEO INTEGRATION Bio-compatable material.  An implant precisely adapted to the prepared bony site. A-traumatic surgery minimize tissue damage. Immobile,undisturbed healing phase. www.indiandentalacademy.com
  10. 10. CLINICAL IMPLANT COMPONENTS IMPLANT : -Titanium, Calcium-Phosphate Ceramics. -Threaded / Non threaded, with or without HA coating, Plasma spray. www.indiandentalacademy.com

  13. 13. ABUTMENT www.indiandentalacademy.com
  14. 14. IMPRESSION POST This facilitates the transfer of the intra oral location of the fixture or the abutment to a similar position in the laboratory cast. www.indiandentalacademy.com
  15. 15. LABORATORY ANALOUGE Is a component machined to exactly represent either the implant or the abutment in the laboratory cast. www.indiandentalacademy.com
  16. 16. TYPES OF IMPLANTS SUB-PERIOSTEAL IMPLANTS TRANS OSTEAL IMPLANTS END OSTEAL IMPLANTS BLADE IMPLANTS www.indiandentalacademy.com

  21. 21. SUCCESS CRITERIA Individual unattached Implant is immobile when tested clinically No evidence of Peri Implant radiolucency The mean vertical bone loss is < .02mm annually after the first year No persistent pain,discomfort or infection is attributable to the Implant The Implant design does not preclude placement of a crown or prosthesis with an appearence the is satisfatory to the patient and the dentist www.indiandentalacademy.com
  22. 22. OSSEO INTEGRATION SEM study showing intimate contact b/w bone(blue) & Ti interposed b/w bone and body of implant www.indiandentalacademy.com
  23. 23. SURFACE OF IMPLANT SEM study shows Implant surface characterized by presence of pores. www.indiandentalacademy.com
  24. 24. PORES ENLARGED Pores resemble VOLCANO. www.indiandentalacademy.com
  25. 25. HEALING Emanating from existing bone, new bone is formed by osseo conduction directly on the implant surface following the contour of the threads. The osteogenic cells differentiate into osteoblasts. By this,always new osteogenic cells, socalled pre osteoblasts,must be recruited from stem cells and have to migrate to the front part of bone formation. www.indiandentalacademy.com
  26. 26. Pre osteoblasts form cytoplasmic extentions,socalled pseudopodia, which are important for both cell attachment and migration on solid surfaces. By means of pseudopodia, pre osteoblasts make use of porous structures of implant surface to migrate and become attached. www.indiandentalacademy.com
  27. 27. Pre osteoblasts become differentiated into osteoblasts and start the secretion of bone matrix. Subsequently, the collagenous bone matrix becomes minerallized and deposites of woven bone are formed directly on the implant surface. There by, initially a small band of woven bone follows the contour of the threads.This small band broadens and matures to lamellar bone. www.indiandentalacademy.com
  28. 28. IMPLANT ATTACHMENT SEM micrograph showing a pre osteoblast attached by pseudopodia to the pores of implant surface www.indiandentalacademy.com
