Implant Location Ideally, occlusal forces should be directed along the long axis of the implants. After a surgeon drills a small hole where your missing tooth’s roots once were, the fixture is surgically placed in the jawbone, acting as your implant’s “roots.” During the healing process, the fixture fuses with the jawbone in a process known as osseointegration, which allows the implant to reside in your mouth permanently.

Implant design (root-form) Cylindrical Implant Some investigators explain the lack of bone steady state by overload due to micromovement of the cylindrical design, whereas others incriminates an inflammation/infection caused particularly by the very rough surfaces typical for these types of implant. The distance between the two lines can then be measured. A suggested maximum cantilever would be 1.5 times this distance. Some are screw-shaped, others are cylindrical, or even cone-shaped or any combination thereof. Views: 678, By: medhelp What treatment will result in the best cosmetic outcome? Dental Implants Of The Future - PowerPoint PPT Presentation. The plate long screw posts The two attachments Transosseous implant. Bruxism is a significant component of failed implants. POLYCARBOXYLATE CEMENT • Uses : – Cementing medium – Intermediate base – Temporary restorative material • Composition – Powder. The insertion torque should be of a moderate level because strong insertion torques may result in stress concentrations around the implant, with subsequent bone resorption. The primary ingredients of zinc phosphate cement powder are zinc oxide and magnesium oxide. 1-Implant body . Biomechanical load management is dependent on two factors: the character of the applied … – Liquid. Medicine and dentistry have made tremendous progress in the last two or three decades. Indications for Dental Implants Increasing the support, stability, and patient satisfaction for a full lower denture Increasing the patient's comfort in chewing Increasing the patient's confidence in smiling and speaking Increasing the patient's overall psychological health Replacing one or more teeth as single units with crowns Aesthetics Providing support for a partial denture, Biocompatibility of Dental Material Desired Mechanical Properties • High yield strength • Modulus close to that of bone’s • Changes in environment around implant Surfaces • Composition • Ion release • Surface modifications, Dental Metallic Implant Surface • Problem: – Dental implant surface change with time due to oxidation, precipitation… • Possible solutions: – Oxide layers ( minimize ion release) – Prosthetic component from noble alloys – Phase stabilizers other than Al & V (eg. Cool new PPT theme with dental - dentist checking and selecting color backdrop and a coral colored foreground. You can also use our Free Templates as Google Slides Themes. Implant design (root-form) Cylindrical Implant Some investigators explain the lack of bone steady state by overload due to micromovement of the cylindrical design, whereas others incriminates an inflammation/infection caused particularly by the very rough surfaces typical for these types of implant. Surgical technique Minimal tissue violence at surgery is essential for proper osseointegration. Presentation design consisting of patient and female dentist in dental office, equipment, chair, oral hygiene. One method is to draw a line through the most anterior implant, and another through the two most posterior implants. Osseointegration Definition: A time-dependant healing process where by clinically symptomatic rigid fixation of alloplastic materials is achieved, and maintained, in bone during functional loading. There is a risk of infection and other complications. A suggested maximum cantilever would be 1.5 times this distance. Diese PowerPoint-Vorlage bietet mehrfarbige Farbbänder, die Ihrer Präsentation … After treatment planning, the buccal and lingual full-thickness flaps are elevated to extend beyond the sulcular depth and an accurate impression of the bony ridge is made, using a hydrophilic impression material (e.g. Microscopic design includes implant materials, surface morphology, and surface coatings. One study had a design that involved implant placements in 6 mongrel dogs; 2 implants were placed in each side of the mandible by either FT or FL procedures. To enhance initial stability and increase surface contact, most implant forms have been developed as a serrated thread. INDIAN DENTAL ACADEMY Dental Implant Treatment Planning and Types of Dental Implants How many teeth are missing?

Here you are at dental implant powerpoint templates page! FEA has become an increasingly useful tool in the past few decades. The latest techniques have been invented to cure a toothache or make the teeth white and flashing. Preliminary Evaluations for Implants (Cont’d) Medical evaluation The dentist assesses any existing medical conditions that could worsen as a result of the stress of implant surgery. Advantages & disadvantages of implant over conventional treatment Implants do not involve preparation of the adjacent teeth, they preserve the residual bone, and excellent aesthetics can be achieved. Careful cooling while surgical drilling is performed at low rotatory rates Use of sharp drills Use of graded series of drills Proper drill geometry is important, as intermittent drilling. – Not inherently radiopaque though addition of radiodense additives such as barium can alter radiodensity, Composite Fillings • Mixture of glass or quartz filler in a resin medium that produces a tooth-colored filling • Provide good durability and resistance to fracture in small-to- mid size restorations that need to withstand moderate chewing pressure • Less tooth structure is removed when the dentist prepares the tooth, and this may result in a smaller filling than that of an amalgam • The cost is moderate and depends on the size of the filling and the technique used by the dentist • It generally takes longer to place a composite filling than what is required for an amalgam filling • The cavity must be kept clean and dry during filling, Composite Resin Fillings (FDA) • The most common alternative to dental amalgam • Sometimes called “tooth-colored” or “white” fillings because of their color • Made of a type of plastic (an acrylic resin) reinforced with powdered glass • Advantages: – Require minimal removal of healthy tooth structure for Placement • Disadvantages: – May be less durable than dental amalgam and may need to be replaced more frequently -- Discoloration over time, Indirect Restorative Dental Materials • Porcelain-fused-to-metal – Provides strength to a crown or bridge – Very strong and durable – More of the existing tooth must be removed to accommodate the restoration – Highly resistant to wear – Allergic reaction may appear with by the using metals, Dental Implantation • Dental extraction: The most frequent surgical procedure performed upon humans • Traumatic, congenital, or metabolic causes So • Denture: the most frequently employed prosthesis – Complete or partial – Fixed • Most desirable – Removable • Most often, because of ease of production as well as economy Complete, removable dentures are the prosthetic replacement used by most edentulous people, Alternative Solutions Partial and Full Dentures Crowns Bridges, Dental Crowns • In a dental crown the tooth is restored with the help of some material (porcelain) which is lined over the top of a tooth • Are used mostly to repair the look of the teeth, Dental Bridges • Multiple crowns fused together, Types of dental implant Subperiosteal implants – Typically lie on top of the jawbone, but under gum tissues – Do not penetrate into the jawbone – Cobalt based • Endosseous implants – Surgically inserted into the jawbone – Titanium and titanium alloy, aluminum oxide, and surface coatings of hydroxyapatite • Transosseous implants – Surgically inserted into the jawbone – Penetrate the entire jaw – Secured with a device similar to a nut and a pressure plate, Sub-periosteal implant Severely resorbed, toothless lower jaw bone, which does not offer enough bone height to accommodate Rootform Implants as anchoring devices, Bone Grafting • Bone grafting to rebuild reduced jawbone • Fill in jawbone defects allowing the placement of dental implants • Autografts usually the hip • Allografts are taken from human donors • Xenografts are harvested from animals most commonly bovine (cow) • Alloplastic grafts are inert, man made synthetic materials, Endosteal or Endosseous implant Plate-form implant : Made of pure titanium • With one or two metal on one long side like fork • Placed in the jaw to support crowns or bridges, Endosteal or Endosseous implant B. Ramus-frame implant Designed for the toothless lower jaw only • Surgically inserted into the jaw bone in three different areas – The left and right back area of the jaw – The chin area in the front of the mouth.
