Positioning handles and occlusal locks have evolved as improvements to the Teeth-in-a-Day protocol. These improvements have enabled a more accurate alignment of the removable dental prosthesis during the conversion prosthesis technique. These improvements can be easily incorporated through computer-aided design and computer-aided manufacturing digital denture fabrication process.

BACKGROUND Acceptable short-term survival rates (>90 %) of mini-implants (diameter < 3.0 mm) are only documented for mandibular overdentures. Sound data for mini-implants as strategic abutments for a better retention of partial removable dental prosthesis (PRDP) are not available. METHODS/DESIGN The purpose of this study is to test the hypothesis that immediately loaded mini-implants show mor...

Orbital defects with total loss of eyelids and the eyeball cannot be satisfactorily repaired by reconstructive surgery. Therefore, a prosthetic placement is treatment choice to return individual’s confidence producing an acceptable lifelike appearance. Male patient, 31 years old, came history exenteration surgery four months ago on right eye because infection few before. Patient wanted orbital ...

Fixed implant-supported prosthesis for the edentulous maxilla has gained tremendous popularity over the years. Multiple prosthetic designs have been introduced in order to accommodate a gamut of clinical situations. Irrespective of the design, it is paramount that the esthetics imparted by the prosthesis be uncompromised. Though esthetics is subjective, a common ground exists where all its fund...

aSenior Lecturer, Department of Oral Rehabilitation. bStudent, Master Dental Technology program, Department of Oral Rehabilitation. (J Prosthet Dent 2009;101:73-74) The treatment of choice for a partially edentulous patient is placement of a fixed partial denture supported by either teeth or implants.1 However, when implants are contraindicated or when the remaining abutment teeth cannot suppor...

The abutment(s) of a partial fixed dental prosthesis (PFDP) should have a minimal total occlusal convergence (TOC), also called a taper, in order to ensure adequate retention of a PFDP that will be made for the abutment(s), given the height of the abutment(s). This article reviews the concept of PFDP abutment TOC and presents an alternative definition of what TOC is, defining it as the extent t...

Introduction: Retention of provisionallycemented implant-supported restorations plays an important role in success of the treatment. Uncemented restorations may cause several problems such as restoration swallowing, increased bone loss and prosthesis failure. Therefore, suitable cement compromising between retention and retrievability as well as extra-means of abutment retention might be prefer...

Fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. This is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). If the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among the resto...

Full arch implant-supported prostheses following Branemark protocol are widely used for oral rehabilitation of people with edentulous jaws and associated to the full upper conventional prosthesis. Their indication requires that the dental surgeon be prepared for prosthetic-surgical approach and planning. Therefore, this work aims to present the planning and execution of a lower arch implant-sup...
