Use of transforming growth factor-β loaded onto β-tricalcium phosphate scaffold in a bone regeneration rat calvaria model.

Background: Transforming growth factor-β (TGF-β ) enhances mesenchymal stem cell (MSC) differentiation into osteoblasts.

Purpose: The aim of the study was to assess whether TGF-β loaded onto β-tricalcium phosphate (β-TCP) synthetic scaffold enhances bone regeneration in a rat calvaria model. The release kinetics of TGF-β from β-TCP scaffold was evaluated in vitro.

Soft and Hard Tissue Changes around Tissue-Oriented Tulip-Design Implant Abutments: A 1-Year Randomized Prospective Clinical Trial.

Background: The advantages of platform switching using narrower abutments remain controversial. Many researchers suggest that platform switching can yield enhanced clinical results, while others remain skeptical. We hypothesize that the effectiveness of platform switching might be associated with the degree of reduction in size of the abutment.

Dynamic high-resolution sonography compared to magnetic resonance imaging for diagnosis of temporomandibular joint disk displacement.

Objectives: The purpose of this study was to determine the value of dynamic high-resolution sonography for evaluation of temporomandibular joint (TMJ) disk displacement compared to magnetic resonance imaging (MRI) with the mouth closed and during the maximal mandibular range of motion.

Methods: Dynamic high-resolution sonography with the mouth closed and during the maximal mandibular range of motion was performed on 39 consecutive patients (78 joints; 13 male and 26 female; age range, 18-77 years; mean age ± SD, 37.23 ± 16.

Oral and dental restoration of wide alveolar cleft using distraction osteogenesis and temporary anchorage devices.

Closure of large alveolar clefts and restoration by a fixed bridge supported by implants is a challenge in cleft alveolus treatment. A major aesthetic concern with distraction osteogenesis is obtaining a predictable position of the implant in relation to the newly generated bony alveolar ridge. We describe the treatment of a large cleft alveolus and palate reconstruction by distraction osteogenesis utilizing temporary anchorage devices (TADs) followed by a fixed implant-supported bridge.
