Oral implants are usually placed in the mandibular and maxillary bone and sometimes in additional bone structures such as the zygomatic, pterygoid or vomer bone. In order to identify relevant anatomical structures, diagnostic evaluation of the anatomy...
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...
The primary goal is a proper oral function. This implies not only chewing but also speaking, smiling. Patients’ adaptability varies enormously. Some are satisfied with removable dentures, others object to the esthetics of...
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...
Digital treatment planning protocols, introduction
Spiral or Cone Beam CT (CBCT) data sets of the patient jaw bones and of the scan template are transcoded by a specific software to produce three-dimensional (3-D) images of the jaw bones and thickness of the mucosa. Software planning...
Implant placement with open flap procedure - mandible
The surgeon should be standing or be seated behind the supine patient. Bilateral truncular anesthesia is needed. The incision can be crestal or at a distance in the labial fold. Presence of keratinized tissue both labially and palatally should...
Incision can be made either on top of the crest or at some distance in the labial fold. The outcome for both approaches seems comparable. A sagittal release incision at the midline eases the reflection of the labial mucoperiosteum. It is logical to try to achieve...
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...
Insertion torque represents the resistance of bone during implant placement. Since too low a torque corresponds to low initial mechanical implant stability and too high torque levels lead to avascular periimplant bone...
