Cement-retained restorations are a traditional design to attach a restoration (crown, bridge) to an implant-retained abutment, similar to cementing a crown or bridge restoration on a natural tooth. With the traditional, relatively...
Frameworks are veneered with veneering materials, to design the esthetics and shape of the definitive restoration. Framework material options for acrylic veneering include titanium, (CrCo) Cobalt - Chrome and precious alloys...
Frameworks can be made from titanium, zirconia, precious alloys and Co-Cr base alloys and can be cement-retained or screw-retained. With minimal bone resorption, a ceramo-metal restoration is preferable to accommodate interarch...
Implant-based prostheses can be cement-retained, screw-retained or a combination of both (Fig 1). By definition, an abutment is a component that is intermediate between the implant and the restoration and it is usually screw...
Advantages of abutment-supported prostheses are 1) When implants are not parallel to each other, the use of angulated abutments can "correct" for the non-parallelism 2) Angulated abutments are available for a screw-retained prosthesis and 3) Custom abutments can be...
With appropriate pre-drilling based on their shape upon insertion into the bone, tapered implants will achieve a gradually increasing contact pressure with the surrounding bone and thus provide a high primary stability. This primary...
The treatment of the edentulous jaw can be a mixture of placing implants in healed and fresh extraction sockets. Unequal hard and soft tissue levels around the implants (Fig. 1&2), especially in the interforaminal region, can be adjusted by leveling the bone...
Removable prostheses should always be removed over night. Since the acrylic denture base is tightly covering the keratinised mucosa, it often leads to fungal/candida infections of the ginigiva under the prosthesis....
This is the reversible inflammatory process in the soft tissues around functioning implants. Peri-implant mucositis occurs in almost 60% of subjects (± 30% of sites), restored with implants. Diagnosis is stated by clinical examination: redness, ...
At this appointment, a careful evaluation of the patient's oral hygiene and soft tissue response is performed and adjustments made as needed. A daily home-care program must be customized to the individual's ability to clean the...
Placement of a provisional prosthesis takes place by attaching the conversion denture (either patient's exisiting prosthesis or a new conversion denture) to the implants or to implant abutments. The provisional prosthesis can be...
Inflammation can be limited to the soft tissue around the implant (mucositis) or involve the underlying bone tissue as well (peri-implantitis). Infection can be caused by various risk factors, such as inadequate hygiene and patient compliance...
Presence/number of implants influences aerobe and anaerobe species in saliva and on tongue in edentulism. Subgingival microbiota in periimplantitis vary according to studies. Less periodontal pathogens than in partial edentulism. Prevotella nigrescens,...
All tissue surfaces, prosthesis surfaces and implant surfaces should be accessible by oral hygiene aids like toothbrushes, interdental brushes and dental floss or dental tape. It is paramount that, during treatment planning...
The regular recall control appointment, at least every 6 months, should comprise a hygiene check by the dental/oral hygienist or other auxiliary, and include professional cleaning of the restoration, prosthetic components, sulcus and any...
