A successful dental prosthesis or a restoration is mainly dependent on the accuracy of impressions. An impression an imprint produced by „the pressure one thing upon into surface another‟ negative likeness. It not technically possible desirable to fabricate prostheses restorations directly in patient‟s mouth. Therefore it essential obtain cast model which must be accurate replicas denture beari...

Figure 1.Maxillary PVS impression demonstrating defect in palatal region. A maxillary complete denture (CD) impression often demonstrates a defect in the palatal region of the edentulous arch. This problem commonly relates to air trapped in the impression material or mishandling of the tray seating; the bubble formed in the impression can compromise the fit of the CD or impair tissue health. On...

The accurate duplicate cast obtained from a single impression reduces the profession clinical time, patient inconvenience, and extra material cost. The stainless steel working cast model assembly consisting of two abutments and one pontic area was fabricated. Two sets of six each custom aluminum trays were fabricated, with five mm spacer and two mm spacer. The impression methods evaluated durin...

BACKGROUND Accurate impression making is an essential prerequisite for achieving a passive fit between the implant and the superstructure. The aim of this in vitro study was to compare the three-dimensional accuracy of open-tray and three closed-tray impression techniques. MATERIALS AND METHODS Three acrylic resin mandibular master models with four parallel implants were used: Biohorizons (BI...

OBJECTIVE To compare the diagnostic performance of six different approaches for assessing myometrial infiltration using ultrasound in women with carcinoma of the corpus uteri. METHODS Myometrial infiltration was assessed by two-dimensional (2D) transvaginal or transrectal ultrasound in 169 consecutive women with well (G1) or moderately (G2) differentiated endometrioid type endometrial carcino...

OBJECTIVE To investigate the agreement between conventional colposcopic impression, dynamic spectral imaging (DSI) colposcopy and histology, for human papillomavirus type 16-positive (HPV16(+)) and non-16 high-risk (hr) HPV(+) women. DESIGN Prospective, comparative, multicentre clinical trial. SETTING Three colposcopy clinics in the Netherlands. POPULATION Women (n = 177) aged 18 years or...

Making an impression of the anophthalmic socket to facilitate the design of a custom made ocular prosthesis is a common practice. Different impression techniques can be used for its fabrication. The modified impression technique described here requires minimum laboratory procedures as the preliminary impression, secondary impression and wax trial can be done as a single stage procedure.

BACKGROUND The objective of this study was to evaluate the topographic relationship between the morphology of the greater tubercle and the insertion of the tendon of the infraspinatus. MATERIALS AND METHODS First, we defined an impression of the greater tubercle, which has not been recognized in classic textbooks, as the "lateral impression" and then measured the dimensions of the "lateral im...
