The goal of this study was to provide data relative to the use of a new implant system (Mac System, Cabon, Milan, Italy) with a Morse taper implant-abutment connection for single implant restorations. The implant system is composed of an endosseous screw made of commercially pure titanium grade 2, while the abutment is titanium alloy (Ti-6Al-4V). A total of 80 single implants were placed in 69 ...

Distal extension removable partial denture (RPD) can cause stress on supporting hard tissues, which may lead to harmful effects. The purpose of this study is to investigate the pattern of these stresses over the residual alveolar ridge and alveolar bone around the abutment teeth by distal extension conical crown retained te lescop ic dentures (CCRTDs) with different taper angles using three dim...

objectives : this finite element method study aimed to compare the amount of stress on an isolated mandibular second premolar in two conventional reciprocal parallel interface designs of removable partial dentures (rpds) and the same rpd abutment tooth (not isolated). materials and methods: a kennedy class 1, modification 1 rpd framework was simulated on a 3d model of mandible with three differ...

Purpose: The abutment teeth of removable partial dentures are susceptible to root surface caries and secondary caries, and such caries sometimes result in crown destruction. In particular, in aged patients, this risk increases due to age-associated gingival recession, periodontal disease, decreased amount of saliva, and inadequate brushing caused by decreased finger motor function. Fluoride-rel...

For patients who require removal of anterior teeth due to periodontal problems there are a multitude of treatment considerations. Using the natural tooth as a pontic offers the benefits of being the right size, shape and color. This paper describes the immediate replacement of an anterior tooth using a preimpregnated fiber-reinforced composite with the natural tooth as the pontic. The abutment ...

provisional cements are commonly used to facilitate retrievability of cement-retained fixed implant restorations; but compromised abutment preparation may affect the retention of implant-retained crowns.the purpose of this study was to investigate the effect of abutment design and type of luting agent on the retentive strength of cement-retained implant restorations.two prefabricated abutments ...

Introduction: Diabetes is the most common medical complication in pregnancy. Various risk factors have been mentioned for gestational diabetes, but just a few studies have assessed a relationship between periodontal disease and gestational diabetes. This study was conducted to determine the relationship between periodontal disease and gestational diabetes in clients of selected health- care cen...

context the aim of this review was to examine evidences for the association between smoking and periodontal disease, to discuss possible biological mechanisms whereby smoking may adversely affect the periodontium, and to consider the effect of smoking on periodontal treatment. evidence acquisition a web-based search in pubmed and google scholar was performed to identify publications regarding t...
