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...
Accurate implant planning is the first step to achieve an optimum prosthetic result. Well-fitting, well-designed dentures can directly be used for planning and pre-surgical analysis or a new tooth arrangement and mock-up have to be considered...
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, ...
The open tray technique for making a definitive impression is one of two choices (the other being a closed tray impression) in the fabrication of a fixed complete denture. The open tray technique is specifically indicated, when the implants are not...
At this appointment, the prosthesis framework is evaluated for accuracy of fit, appropriate contour to faciltate oral hygiene access and the necessary balance of structural morphology for rigidity/strength and sufficient space to...
Placement of a provisional prosthesis takes place by attaching the conversion denture (either patient's exisiting prosthesis or a new conversion denture) to the implants or to implant abutments. The provisional prosthesis can be...
The trial placement appointment is a significant one for successful edentulous patient care. It will be the first time that dentist and patient can see what has been created in the laboratory; and a decision will then be one...
One goal in the treatment of the fully edentulous patient is to re-establish the maxillo-mandibular relation in the transversal and sagittal dimensions comprising adequate facial height. The occlusal contact situation be...
It is important to evaluate whether the implants are parallel to each other. If the implants are fairly parallel to each other (Fig 1) a closed tray impression technique can be employed. Since the implants are parallel to each other, the polymerized...
In vitro research studies have compared splinted versus unsplinted impression techniques and have, in general, shown that the splinted impression technique yields more accurate master casts when compared to a reference...
The goals of an impression are to accurately capture tissue contours necessary and relevant for fabrication of a prosthesis that adapts well to mucosa or a prosthesis that fits well and passively on implants...
A fixed implant prosthesis is completely anchored and supported by dental implants. There are different terms used to describe a fixed implant prosthesis, such as fixed complete denture, fixed detachable prosthesis, the hybrid prosthesis, or the...
The relative merits of different prosthodontic treatment objectives - resilient versus rigid attachments - are controversial and empirical. A resilient retention mechanism is recommended on the assumption that this will protect implants from overload; while in...
At post-placement visits, the same factors evaluated carefully at the placement appointment should be reviewed and adjusted where necessary. Overdenture base fit, extensions, occlusion, esthetics, function, comfort and overall patient...
