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...

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...

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...

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...

The choice of anesthesia depends on many variables including the complexity of treatment, duration of treatment, need for patient awareness and the response during treatment, only to name a few. In general, the clinician and patient should discuss the...

The aims of peri-implant soft tissue management in the edentulous mandible are the eventual reconstruction of attached gingiva or immobilizing the soft tissue at the implant-soft tissue interface. Vestibuloplasty means deepening of the...

Teeth extractions are followed by a reduction of the bucco-lingual as well as the vertical dimension of the residual alveolar ridge. The ensuing resorption is progressive and even the basal jaw may become involved. In the lower jaw, the....

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 the beginning of the recall control it is necessary to define the intention of a radiograhical control and if it is needed. Radiological controls are only justified in the presence of certain symptoms, anamnesis and/or clinical examination...

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,...

As described in Patient Assessment, a thorough evaluation of patient factors influencing whether to proceed with surgical therapy is relevant.
Depending on the tpe of surgery prescribe pre-operative medication (for example antibiotic coverage), if...

Physiological salivary output is 0.75 to 1.5 liters per day, with most originating from the submandibular glands. Saliva is a lubricant and has a complex set of protective and healing functions for the oral cavity. It adheres instantly to...

Epithelial desquamation in the oropharynx limits bacterial accumulation, except on the tongue dorsum and in the tonsillar crypts. Loss of teeth dramatically reduces the load of periodontal pathogens except for Aggregatibacter actinomycetemcomitans and to a...

Radiographical check-ups to evaluate bone levels cannot be repeated too often to avoid unnecessary radiation. Monitoring the overlying soft tissues may help to identify eventual problems of the underlying bone, although the correlation...
