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...
Implant supported overdentures are an evidence-based treatment option for edentulous patients leading to a significantly increased quality of life.
There are various retention elements available which connect the implants directly...
Implant overdentures are an excellent treatment option for edentulous patients and lead to significant improvement of quality of life. There are various options for their retention mechanism...
Less than 4-6 mm of vertical residual bone height in the posterior segment of the maxilla is an indication for a sinus augmentation procedure [Esposito]. The external access to the maxillary sinus is carried out at a lateral buccal alveolar...
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...
In the edentulous upper jaw implant insertion can be limited due to the adjacent anatomical structures (nasal floor, maxillary sinus). Less than 5-6 mm in height and 6 mm in width requires augmentation before implant placement....
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....
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...
The relative merits of different prosthodontic treatment objectives - resilient versus rigid attachments - are controversial and empirical. A resilient retention mechanism is recommended on the assumption that this will protect implants from overload; while in...
At post-placement visits, the same factors evaluated carefully at the placement appointment should be reviewed and adjusted where necessary. Overdenture base fit, extensions, occlusion, esthetics, function, comfort and overall patient...
Placement of a removable prosthesis requires attention to detail to cover all important clinical items such prosthesis fit, denture base extensions, esthetics, occlusion, patient comfort and post-insertion instructions. Implant overdentures may or may not...
