A commonly used option for fixed restorations is a metal or zirconia framework with ceramic or acrylic veneering. The amount of alveolar bone resorption determines whether teeth or teeth and soft tissue must be replaced...
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...
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, ...
Impression making in implant overdenture therapy simultaneously records healthy available denture-bearing tissue surfaces and implants’ positions in edentulous arches. The objective is a shared retention and...
Impression taking for a complete denture records available denture-bearing tissue surfaces. An ideal force distribution pattern based upon the load bearing capacity of supporting tissues is desirable while avoiding dislodging by the oro-facial...
Treatment planning for the edentulous patient requires a diagnostic tooth arrangement which provides valuable information for pre-surgical planning (surgical guide fabrication), facilitates discussion regarding...
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...
