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...
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...
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...
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 majority of commercially available implants are variations of Brånemark’s original design of a screw which he coined as 'fixtures'. This has been the starting point for numerous current market variations that incorporate convergent themes of implant material...
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,...
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...
Head and neck cancers is mainly represented by head and neck squamous cell carcinoma (HNSCC). Incidence in males is higher than in females (2,8:1). Human papilloma virus (HPV) has been demonstrated to be related to the increased...
Most patients’ mouth opening readily permits access for routine prosthodontic and surgical treatment interventions. Limited mouth opening or microstomia is encountered in patients exposed to sclerodermia, diffuse systemic...
Children and adolescents (during ongoing bone/skeletal development), unless in selected anodontia patients. However, implant placement for orthodontic treatment purposes is indicated.
Uncontrolled metabolic diseases such as Diabetes Mellit...
