ÖZET A hyperplastic pulpitis (pulp polyp) case was reported at the centre of a bridge abutment tooth associated with extensive caries and periapical radiolucency in a middle-aged female patient contrary to the fact that it usually develops in a large open cavity. A 31-year-old-female patient had a bridge from 35 to 37 on her mandibular left side. She had discomfort in her mandibular left second...

Abstract The masonry bridges on the Kalka Shimla Mountain Railway line, which have multiple arch galleries in form of Roman aqueducts, are spectacular. line is situated severe seismic zones (Indian Standard 1893:2016). This research assesses vulnerability Bridge No. 541 line. bridge tallest route. In particular, it using finite element (FE) analysis. For this purpose, an FE model for developed ...

The guardrail is an indispensable part of ballasted track structures on bridges. In order to reveal its influence the track–bridge interaction continuous welded rail (CWR), longitudinal resistance model fastener and influential factors are established through tests. By taking a girder bridge (CGB) for railways as example, stock rail-guardrail-sleeper-bridge-pier integrated simulation developed....

OBJECTIVE The aim of this study was to evaluate the influence of removable partial dentures (RPD) on the periodontal health of abutment and non-abutment teeth. MATERIALS AND METHODS A total 107 patients with RPD participated in this study. It was examined 138 RPD, they were 87 with clasp-retained and 51 were RPD with attachments. The following periodontal parameters were evaluated for abutmen...

PURPOSE This study evaluated the influence of abutment materials on the stability of the implant-abutment joint in internal conical connection type implant systems. MATERIALS AND METHODS Internal conical connection type implants, cement-retained abutments, and tungsten carbide-coated abutment screws were used. The abutments were fabricated with commercially pure grade 3 titanium (group T3), c...

Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...

PURPOSE This study examined the effects of the abutment types and dynamic loading on the stability of implant prostheses with three types of implant abutments prepared using different fabrication methods by measuring removal torque both before and after dynamic loading. MATERIALS AND METHODS Three groups of abutments were produced using different types of fabrication methods; stock abutment, ...
