Slide 1-

BASIC CONCEPT OF DENTAL IMPLANT “An artificial dental root that is surgically inserted into the jaw bone &that can be used by the dentist as platform for prosthesis”
Slide 2-

HISTORY OF DENTAL IMPLANT 1950s P.I.Branemark & associates 1965 first patient 1976 Schroder et al. 1978 Schulte(German) 1981 Albrektsson
Slide 3-

OSSEOINTEGRATION “A direct structural&functional connection between bone and the surface of a load-carrying implant”(Branemark 1960) Fibro-osseous integration -soft tissue(fibres)interposed between the implant surface & bone Biointegration -implant is covered with bioactive material like hydroxyapatite
Slide 4-

RATIONALE FOR IMPLANT THERAPY Tooth loss related to age Anatomic consequences Poor performance of RPD Predictable long term results of implant-supported prosthesis Eliminating the need to grind healthy tooth
Slide 5-

CLASSIFICATION OF DENTAL IMPLANT Based on type of Anchorage -submucosal -subperiosteal -transosteal -endoosteal
Slide 6-

CLASSIFICATION OF DENTAL IMPLANT Contd.. Based on shape&form Root form-solid cylinderical/tapered -pin type -screw type -basket type -hollow cylinder
Slide 7-

CLASSIFICATION OF DENTAL IMPLANT Contd… Blade form-conventional blade design -vented blade design Based on the surface texture -surface with pure titanium -acid-etched surface -porous beaded surface -hydroxyapatite coated
Slide 8-

PERI-IMPLANT MUCOSA Dense lamina propria covered by stratified squamous keartinized epithelium Implant-epithelium junction is analogous to the JE Epithelial cells attach to the titanium implant by means of hemidesmosomes&basal lamina Sulcus arround implant lined by sulcular epithelium
Slide 9-

PERI-IMPLANT MUCOSA Contd.. Depth of sulcus 1.5-2.0mm Collagen fibers are nonattached¶llel due lack of cementum Marginal periimplant mucosa contains significantly more collagen&fewer fibroblasts Periodontal ligament absent Biologic width(3-4mm)=epithelial attachment(2mm)+supracrestal CT(1-2mm)
Slide 10-

VASCULAR SUPPLY&INFLAMMATION Limited due to lack of Pdl Capillary loops below JE&SE similar to normal periodontium Inflammatory response similar to periodontal tissue
Slide 11-

TEETH vs. IMPLANTS Lack of Pdl Implant can not intrude/migrate Proprioception -ce C/I in growing individuals Overload/parafunctional habits cause microstrain/microfracture in bone bone loss
Slide 12-

TEETH vs. IMPLANTS Contd..
Slide 13-

MCQ-1 Which of the following shows the difference between peri-implant and periodontal mucosa (a)Stratified squamous keratinized epithelium (b)Sulcus lined with sulcular epithelium (c)Viable bioloigic seal between implant and epithelial cells (d)Attachment of collagen fibers
Slide 14-

MCQ-2 The term which describes the ultrastructural contact between bone and implant is (a)Fibrous integration (b)Osseointegration (c)Ankylosis (d)Bonyintegration
Slide 15-

MCQ-3 The less frequently used dental implant biomaterial is Alloys of titanium aluminum Vanadium Platinum
Slide 16-

MCQ-4 The most widely used dental biomaterial in implantology is (a)Gold (b)Chromium (c)Nickel (d)Titanium
Slide 17-

MCQ-5 Which of the following is responsible to prevent the attachment of collagen fibers to the implant surface (a)Plasma sprayed implant surface (b)Biocompatibility of implant surface (c)Absence of cementum on implant surface (d)Acid etched/ blast implant surface
