Implant-based prostheses can be cement-retained, screw-retained or a combination of both (Fig 1). By definition, an abutment is a component that is intermediate between the implant and the restoration and it is usually screw...
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...
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...
Traditional endosseous oral implant treatment protocols ad modum Brånemark required a variable healing period (usually 3-6 months) before prosthesis placement. The healing period was considered necessary to achieve osseointegration and establish a load-bearing interface...
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, ...
Whenever possible, provisional restorations should be fabricated to simulate the desired definitive prosthesis in form, albeit with different and less durable materials. The lessened durability and functional capacity of a provisional restoration...
The patient with a terminal dentition and who faces total teeth extractions can choose from a number of treatment options from immediate complete denture to one of the implant supported protocols.
Immediate dentures are chosen by patients who are unwilling...
Conceptually, a provisional prosthesis for an edentulous patient is a convenient tool that offers the patient a satisfactory level of function and esthetic appearance while definitive treatment is undertaken...
Parafunctional activities can apply high forces to both implant and prosthetic components. These forces can lead to fracture or loosening of screws and abutments, chipping of the veneering material or fracture of the prosthetic reconstruction...
Smoking and nicotine consumption have a constrictive effect on blood vessels thereby reducing blood supply. It increases the susceptibility to periodontal inflammatory diseases, dry extraction sockets and wound healing...
