Aqueous-only, pH-induced nanoassembly of dual pKa-driven contraphilic block copolymers.

pH-Responsive block copolymers, having two segments with functionalities of differing pK(a), were prepared by NMP, providing a "green" route to the assembly of core-shell functionalizable nanostructures.

Fractures of the condylar process: surgical versus nonsurgical treatment.

Purpose: The purpose of this study was to compare outcomes from surgical and nonsurgical treatment of condylar process fractures.

Patients And Methods: Two hundred thirty-four patients with fractures of the mandibular condylar process were treated by open or closed methods. In the follow-up study, 150 patients with a mean follow-up time of 2.

A study of replanted permanent teeth in different age groups.

The purpose of this study was to evaluate the benefits of replanting avulsed permanent teeth in different age groups. Of the 112 replanted teeth, 103 could be examined after 2.5 years on average.

Indications and limitations of three-dimensional models in cranio-maxillofacial surgery.

Anatomical, life-like, three-dimensional (3D) models have a definite place in cranio-maxillofacial surgery. Our experience with 541 computer tomography (CT)-based 3D models employed in aiding corrective surgery of tumours, dysgnathia, traumatology, alveolar atrophy, congenital malformation and asymmetrical malformations in our department is discussed. From July 1988 to February 1997, 3D models of 346 patients were used.

[Replantation of avulsed immature permanent teeth. Results in 39 cases after an average of 2.5 years].

The aim of this investigation was a critical assessment of the short- and medium-term results of replantation of immature, avulsed permanent teeth. Thirty-nine teeth were investigated after 2.5 years on average.
