A commonly used option for fixed restorations is a metal or zirconia framework with ceramic or acrylic veneering. The amount of alveolar bone resorption determines whether teeth or teeth and soft tissue must be replaced...
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...
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...
The tradition to insert 6 implants, and eventually more, in an arch-wide pattern dates back to the early days of osseointegration when implants with a machined surface were used and risk for early...
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...
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....
A choice of occlusal schemes can be employed for the prosthodontic rehabilitation of the edentulous patient. Clinical outcomes with different schemes continue to be debated and no one scheme has emerged as clearly superior. However, although the...
In the rush to meet patient demands for functional rehabilitation, the importance of occlusion is often overlooked. A check of the occlusion should be performed at every visit from insertion onwards because many problems with fixed dental prostheses can...
