Extraction of teeth with persistent periapical lesions requires a specific drilling protocol to remove infected bone, to reach healthy trabecular bone and start up a bleeding. Residual dens sclerotic bone may harbor latent pathogenic microorganisms for a...
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...
In the edentulous lower jaw implant insertion can be limited due to bone resorption processes and the resulting superficial alveolar nerve topography. In the anterior region less than 5-6 mm in height and 6 mm in width requires bone grafting before implant placement...
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 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...
The scientific literature shows that short implants with a length of ≥ 6 mm are able to support prosthetics in the edentulous mandible. After tooth removal the mandible displays different degrees of atrophy (Fig 1&2). Regarding hard tissue management...
3-D imaging seems the best option unless clinical examination reveals an ample bone volume. The bone quality can be derived from density measurements if CT scan images are available or approximately from the trabecular pattern of 2-D images. Pano....
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....
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,...
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...
