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...
Conventional dentures are a common treatment option, but, when bone is missing, they may not meet functional, psychological and social needs of the individual. Classical surgical approaches include different...
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...
In the edentulous upper jaw the placement of implants can be challenging due to limited bone quantity and the presence of the maxillary sinus. Pterygoid implants have high success rates, similar bone loss levels to those 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...
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...
In the edentulous upper jaw the placement of implants can be challenging due to limited bone quantity and the presence of the maxillary sinus. Pterygoid implants present an alternative option to use residual bone for implant anchorage and to overcome the need for...
Zygomatic implants have been documented as a an alternative for the rehabilitation of the atrophic posterior maxilla with both the classical two stage and immediate loading protocols. Zygomatic implants avoid grafting and sinus lift procedures and therefore contribut
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...
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, ...
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,...
The primary goal of angulated implant placement concepts is the implant-based prosthodontic rehabilitation of the edentulous maxilla and mandible and avoiding grafting procedures and thereby offering a more simple and less invasive treatment...
In the atrophic mandible soft tissues become prominent and the inferior alveolar nerve is located more superficially.
Fractures of the atrophic edentulous mandible can occur during implant insertion. Especially in hard bone...
