Reproducing the accurate intraoral relationship of an implant through impression making is first step in achieving fit prosthesis. Traditionally techniques used dentistry can be classified into closed tray and open techniques. Open impressions are considered to more as compared cases with multiple implants. It requires long copings which picked up during procedure thereby reproducing exact impl...

STATEMENT OF PROBLEM Various implant impression techniques, such as the splint, pick-up, and transfer techniques, have been introduced, and some techniques may be more accurate than others. Also, clinically, some factors, including the angulation or depth of implants, may affect the accuracy of the implant impressions. PURPOSE The purposes of this review were to: (1) investigate the accuracy ...

The treatment of patients with oral cancer is complex: a multidisciplinary approach needs to be taken and maxillofacial and oral surgeons, an oncologist, a prosthodontist should be included, and a psychologist is often needed. This case report describes the prosthetic rehabilitation of a patient after surgical removal of oral cancer with obturator prosthesis. Resection cavity was located in cen...

PATIENT A 77-year-old male who had been treated with an upper left maxilla resection for a malignant carcinoma was having difficulty eating with the unstable denture due to a defective jaw. Since dentures made by the ordinary method cannot be fixed firmly to the upper jaw, the functional impression technique was used to produce dentures for the defected jaw. DISCUSSION The patient was satisfi...

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...

the use of multiple implants in the same jaw requires a detailed knowledge of abutment angulation. the position and angulation of the abutments play an important role in treatment planning and fabrication of the custom tray. therefore diagnostic casts that contain cover screws may cause problems during implant therapy. the current article describes a technique for making a preliminary cast with...
