Implant-connected versus tooth-connected implant-supported partial dentures: 2-year clinical and radiographic comparative evaluation.

The purpose of this study was to clinically and radiographically compare implant-connected and tooth-connected implant-supported fixed-detachable mandibular partial dentures. Twenty partially edentulous patients (age range: 25 to 50 years) with mandibular Kennedy Class II configurations were equally divided into two groups receiving a three-unit, fixed-detachable, screw-retained partial denture. Group 1 comprised patients with unilateral missing mandibular molars and premolars.

Paraoxonase-1 and oxidative status in common Mediterranean β-thalassaemia mutations trait, and their relations to atherosclerosis.

Aims: Investigation of paraoxonase-1 (PON1) activity with oxidative status parameters and the increased susceptibility to atherogenesis in β-thalassaemia-trait (BTT) subjects.

Methods: Sixty BTT subjects and 20 age- and sex-matched healthy controls were enrolled in the study. Serum PON1, total antioxidant capacity (TAC), malondialdehyde (MDA) and carotid artery intima-media thickness (CIMT) were determined.

Evaluation of the precision of three implant transfer impression techniques using two elastomeric impression materials.

A master cast representing a completely edentulous mandible was fabricated in polyurethane resin and had four implants secured to the anterior interforaminal area. Impressions were made using six technique-material combinations. Ten definitive casts were fabricated for each technique.
