Teeth loss in the maxilla initiates residual ridge/alveolar resorption, especially in the anterior region, which is flared labially. The consequences of this resorption is a gradual medial or palatal shift of the crest of the maxilla. This...

The peri-implant mucosa consists of an externally located keratinized oral epithelium, which is connected to the peri-implant junctional epithelium facing the abutment. The latter extends approximately 2 mm apical to the...

Missing single teeth imply a variety of bone sites for implant placement. Incisor regions are frequently impeded by inadequate mesio-distal and/or bucco-lingual bone dimensions, whereas second bicuspid/molar regions are generally affected by inadequate...

The process of informed consent requires a thorough communication between healthcare professional and patient. The communication should minimally comprise...

There are several treatment options for a single missing tooth; the most common are an implant-supported crown, a 3-unit fixed partial denture supported by two natural teeth, a fixed resin-bonded fixed partial denture, a removable partial denture...

The application of implants for single-tooth replacements has evolved into a viable surgical and prosthodontic treatment option with reporting of excellent implant survival rates and satisfied patients. Psychological benefits of restoring the dental...

It is helpful if a clinician is situated so that his/her eyes are at the level of the patient's eyes. For example, if the patient is seated, the clinician should also be seated. It is beneficial if the interview between clinician and...

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...

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...

Patients wearing complete dentures often suffer from esthetic and functional discomfort and compromised denture retention and chewing function. Denture adhesives are often applied. Many patients perceive this...

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... 

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...
