Craniectomy and noggin application in an infant model.

Introduction: Noggin is an antagonist of bone morphogenetic proteins (BMP)-2, -4 and -7. Little data are available regarding its clinical utility. Two hypotheses were put forward: firstly, that spontaneous regeneration of calvarial defects with noggin protein would result in diminished bone volume when compared with calvarial defects not so treated.

Determination of facial symmetry in unilateral cleft lip and palate patients from three-dimensional data: technical report and assessment of measurement errors.

Objective: To assess measurement errors of a novel technique for the three-dimensional determination of the degree of facial symmetry in patients suffering from unilateral cleft lip and palate malformations.

Design: Technical report, reliability study.

Setting: Cleft Lip and Palate Center of the University of Erlangen-Nuremberg, Erlangen, Germany.

Immediate versus delayed loading of dental implants in the maxillae of minipigs. Part II: histomorphometric analysis.

Purpose: To assess histomorphometric parameters of dental implants placed in partially edentulous maxillae of minipigs.

Materials And Methods: In 9 minipigs, 6 XiVE implants were placed on each side of the maxilla, either after implant site preparation by an osteotome technique or by spiral drills. The implants were restored with fixed provisional restorations and loaded either immediately or after healing periods of up to 5 months.

Untreated 'blow-in' fracture of the orbital floor causing a mucocele: report of an unusual late complication.

Background: Several severe complications have been described with blow-in fractures. Therefore, immediate surgical treatment of these fractures has been recommended. To date, there is only minimal knowledge on long-term complications of blow-in fractures that have remained untreated.
