The document discusses dental implants, which are root devices made of titanium or zirconium used to replace missing teeth. They fuse directly to surrounding bone through osseointegration. Key parts include the implant body, healing screw, healing caps, and abutments. Implants are classified by placement site (endosteal, subperiosteal, transosteal), materials used, and design. Factors like bone width/height, soft tissues, and smile line must be considered. Precise flap designs are selected based on bone atrophy levels to ensure blood supply. Implant sites are prepared carefully using specialized burs and temperature controls to prevent bone cell death before implant insertion and staged healing
Dental implant in esthetic zone
- 3. NOWADAYS osseointegrated implants are used, which have been proven to be totally biocompatible.
- 4. Dental implant: is a "root" device, usually made of titanium (or may use zirconium), used in dentistry to support restorations that resemble a tooth or group of teeth to replace missing teeth. Osseointegration: is a process refers to the direct fusion between mental implant surface and the healthy surrounding bone.

- 8. Dental implants will fuse with bone; however they lack the periodontal ligament , so they will feel slightly different than natural teeth during chewing.

- 17. SMILE LINE smile line is defined as the relationship between the upper lip and the visibility of the gingival tissue and teeth. Its imaginary line following the lower margin of the upper lip and usually has a convex appearance ; it could be classified in to: high average low
- 18. • The other line is formed by the bottom edge of the upper teeth. Ideally this line should follow the curvature of the lower lip. • A straight flat line is less pleasing. • A reverse curve where the front teeth appear to be shorter than the canines gives a look of aging and wear and can be quite unattractive.

- 22. 3 sided flap
- 23. For single tooth replacement, and If there is sufficient bone available also for esthetic reasons the mucoperiosteal flap should leave a 1mm margin of sound interdental papilla tissue to insure that it maintain fine . length of mucoperiosteal must not exceed two times its width in order not to compromise the blood supply.
- 24. Dr. PAUL A. FUGAZZOTTO (1998) noted the precise flap design should be governed according each individual situation, and not by an overall generic flap design. He categorized implant sites for single-tooth maxillary anterior placement as follows: Class I: Minimal or no ridge atrophy buccolingually or apicocoronally. Class II: Minor buccolingual atrophy with no apicocoronally . Class IIA: Both minor buccolingual and apicocoronally atrophy.
- 25. Class III: Moderate buccolingual ridge atrophy with no apicocoronal deficiency dehiscence and/or fenestration. Class IIIA: The same as Class III, accompanied by moderate apicocoronal ridge atrophy. Class IV: Moderate-to-severe buccolingual ridge atrophy with or without an apicocoronal component; as a result, the hard tissue atrophy precludes ideal implant positioning and necessitates hard tissue augmentation prior to implant placement.
