Single tooth

TG2_1210_thumb_Anterior,-Posterior.png

Anterior and posterior location considerations

Missing single teeth imply a variety of bone sites for implant placement. Incisor regions are frequently impeded by inadequate mesio-distal and/or bucco-lingual bone dimensions, whereas second bicuspid/molar regions are generally affected by inadequate...

Cement-retained restorations, overview

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...

Digital treatment planning protocols, introduction

Spiral or Cone Beam CT (CBCT) data sets of the patient jaw bones and of the scan template are transcoded by a specific software to produce three-dimensional (3-D) images of the jaw bones and thickness of the mucosa. Software planning...

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...

Hard tissue management - mandible

The scientific literature shows that short implants with a length of ≥ 6 mm are able to support prosthetics in the edentulous mandible. After tooth removal the mandible displays different degrees of atrophy (Fig 1&2). Regarding hard tissue management...

Hard tissue management - maxilla

3-D imaging seems the best option unless clinical examination reveals an ample bone volume. The bone quality can be derived from density measurements if CT scan images are available or approximately from the trabecular pattern of 2-D images. Pano....

Alveolar atrophy and insufficiency

Teeth extractions are followed by a reduction of the bucco-lingual as well as the vertical dimension of the residual alveolar ridge. The ensuing resorption is progressive and even the basal jaw may become involved. In the lower jaw, the....

Soft tissue and hard tissue

Removable prostheses should always be removed over night. Since the acrylic denture base is tightly covering the keratinised mucosa, it often leads to fungal/candida infections of the ginigiva under the prosthesis....
