Transcript of Surgical Placement of Dental Implants

Surgical Placement of Dental Implants What Are Dental Implants? A dental implant is a titanium "root" used in dentistry to support restorations that resemble a tooth or group of teeth to replace missing teeth. Introduction Dental Implants are a form of prosthetic (artificial replacement) dentistry, but also is considered a form of cosmetic dentistry. The technical term for the procedure is called a root-form endosseous implant As the implant is set where the extracted tooth was, the bone of the jaw accepts the titanium post. The end result looks and feels like a natural tooth! The use of dental implants permits the unidirectional tooth movement without reciprocal action. How does this relate to class? Oral health contributes to the overall health of people Harmful bacteria grow in the mouth, making it a lot easier to get into other parts of the body The mouth is the largest segway to other major parts of the body.
Failure to replace missing teeth can result in bone loss and shifting of bite What are some reasons for Dental Implants? Tooth Decay
Root Canal Failure
Gum Disease/Periodontitis
Trauma to the Mouth
Congenital Effects BUT!!! The procedure had to start somewhere....... Evolution of Dental Implants The bone of the jaw accepts and osseointegrates with the titanium post. So it looks and Feels like a real tooth! How the procedure is done Composition of Post Titanium Screw, grades 1-4, contains Carbon and Iron Etching or sandblasting is done prior to placement to increase the surface area and the integration potential of the implant. Screw strongly resembles the root of a real tooth Sometimes the Screw has to be altered a little to cater to each individual mouth Preparation for implant Crown Placement Healing Placement of Screw Dead tooth must be extracted first The inferior alveolar nerve or the sinus must be examined, as well as the shape and dimensions of the bone, before to ensure proper insertion A surgical stent is put down first where the missing tooth is Hand osteotomes or precision drills with highly regulated speeds are used to drill a pilot hole where the screw will go The hole is progressively widened with successively larger drills one after another 2-3 weeks after extraction Caution must be taken when drilling because overheating will damage osteoblasts The Implant is inserted using a special screwdriver The screw is driven down into the bone about a half an inch Time to allow the bone to grow on to the surface of the implant is essential (osseointegration) Failure to integrate with the bone, as well as infection and death of surrounding bone tissue if caution is not taken A crown is then fitted and cemented to the top of the screw Each step depends on the quality of bone, size of implant, difficulty of insertion If there is not enough bone available for insertion, a bone augmentation must be performed Sometimes the top surface of the screw must be shaped to cater to a specific tooth The crown is made up of a porcelain blend that is very hard and dense No hard foods for first week Brushing and proper flossing are essential during first month to prevent bacteria from infecting open incisions Research Involved Health Results In 1931, a Mayan body was dug up with fragments of shells inserted into the skeletons mandible dated back to 600 AD
Blade endosseous implants, resembled a flat blade, or subperiosteal implants, was attached with screws to the exposed bone of the jaws
In 1952, the first Dental implant was inserted by Dr. Leonard Linkow
He is known as the father of modern Dental implants
Various metals were attempted but titanium seemed to be the most reliable and sturdy 95% success rate Insurance will not cover this procedure Bone is very difficult to work with and is so variable with each person, that the procedure is assumed different each and every case Failures are more prevalent in smokers, and those with bone disorders Implants are much more efficient than bridges and last longer Increases peoples confidence and likleyhood of a job offer Alternatives References Implants can produce sinus lifting, which improves oxygen intake, and less effects from allergies Taking out a dead tooth can prevent infection Without a proper implant, a missing tooth can cause an irregular bite After an extracted tooth, something must go in its place otherwise loss of bone may occur Implants rather than bridges saves healthy teeth Research showes that people with permanent implants eat better balanced meals Just pull the tooth? Bridges involving two other healthy teeth Requires drilling into enamel of other two teeth If bridge falls out, metal bridges can be swallowed=lawsuit Very tough to clean, leading to infection and decay Never guaranteed, lasts about 2 years The crown is permanently cemented onto the articulating surface of the screw Healing typically takes 2-6 months "Dental Implants | AAOMS.org."
