Number of implants maxilla and mandible

The tradition to insert 6 implants, and eventually more, in an arch-wide pattern dates back to the early days of osseointegration when implants with a machined surface were used and risk for early...

2345-thumb-Implant-supported-vs-abutment-supported.png

Direct to implant vs. abutment

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...

Guided vs non-guided

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...

Closed versus open tray technique

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...

Framework trial placement

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...

Impression - parallel vs non-parallel implants

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...

Attachment selection

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...
