The level of bone crest surrounding the implant is of utmost significance to determine osseointegrated implant success, as preservation of marginal bone height is highly important for long-term dental implant survival. Various approaches have been described in the literature to prevent the crestal bone loss, including platform switching, non-submerged(More)
AIMS The application of a paint-on die spacer onto the dies prior to the fabrication of cast crowns is an acceptable procedure to improve the fit of the restoration. The primary purpose of this study was to evaluate the variation in thickness of different brands of die spacer based on the effect of storage time and application of additional layers. (More)
Maxillofacial trauma refers to any injury to the face or jaw caused by physical force, trauma, the presence of foreign objects, animal or human bites, and burns. Facial defects can be devastating in their impact on physical structure and function of the affected individual, leading to potential compromises in quality of life. Restoration of facial defects,(More)
Prosthodontic management of occlusal wear problems is a demanding task on the part of the prosthodontist. Various factors such as vertical dimension of occlusion, centric relation, occlusal contact pattern, esthetics and phonetics need to be considered simultaneously for both anterior and posterior teeth during occlusal rehabilitation. This may be further(More)
This in vitro study assessed the marginal gap and marginal microleakage in zirconia copings fabricated using two computer aided techniques- CAD milling and Copy milling and cemented to respective tooth preparations using two resin bonding systems, light cure and self-cure resin bonding systems. 32 extracted premolars were prepared to receive zirconia(More)
INTRODUCTION It has been reported that protein containing solutions can accelerate the release of elements from the base metal alloys. AIM This study aims to determine whether the solution in which an alloy is submerged and the exposure time have any effect on the amount of release of elements from the Ni-Cr and Co-Cr alloys. MATERIAL AND METHODS A(More)
This study compared levels of the 2 crevicular enzymes-myeloperoxidase (MPO) and alkaline phosphatase (ALP)-in peri-implant sulcus fluid (PISF) around platform-switched implants (implant group) vs the 2 enzymes' levels in gingival crevicular fluid around contralateral natural teeth (control group). Twenty subjects were selected from a population who were(More)
The use of paint-on die spacer to improve the seating of casting has become quite popular in the recent years. The generally accepted range of paint-on die spacer is approximately 20-40 μm, which suggests a range of tolerance. The painting of the retentive grooves with die spacer has always been a subject of debate. The primary purpose of this study was to(More)
Immediate placement and restoration of the implant is a widely used protocol, but loading of implants in the site which is periapically infected is still not very popular. Very few studies have been conducted and its still in debate. The conventional protocol of placing implant and waiting for it to osseointegrate is time consuming and compromises patients(More)
BACKGROUND The design of the tooth preparation and the cementing medium are important consid-erations in the retention of crowns and fixed partial dentures. The purpose of this invitro study was to determine the effect of axial groove on the retention of complete cast metal crowns using two resin luting cements. METHODS Forty freshly extracted intact(More)
