Background: Primary stability is crucial to implants used for orthodontic anchorage. Bone condensing to enhance primary stability is controversial.
Material And Methods: Fourteen Frialit-2-stepped screw and cylinder implants were placed in the median palatine sutures of 22 cadaveric human heads.
Introduction: During the early development, numerous histological and morphometric changes occur in the cranial sutures the exact knowledge of which is of fundamental significance for understanding clinically relevant cranial anomalies. In this paper a histological and histomorphometric longitudinal study of the coronal, sagittal and lambdoid sutures in the rat is reported in relation to age.
Material And Methods: Forty-eight male Wistar rats (Rattus norvegicus Berkenhout) were raised under standard conditions.

Introduction: Patients with clefts of lip, alveolus and palate show a high incidence of maxillary sinusitis. In order to evaluate sinus size as a factor in sinusitis, this study investigates maxillary sinus morphology in an adult skull with an untreated bilateral cleft.
Material And Methods: The maxillary sinus volume (MSV) of a mixed-sex sample of 140 adult skulls from three different populations was assessed and compared with the MSV of a skull of a 25 year old man showing an untreated complete bilateral cleft.
Orthognathic surgery has become a standard procedure in cranio-maxillo-facial surgery during the past five decades. Based upon the elementary works by Obwegeser who introduced sagittal split ramus osteotomy in the early 1950s, this procedure has become the worldwide gold standard in mandibular orthognathic procedures by now. When devices for ensuring the centric condylar position throughout the entire surgery were introduced by Luhr in the early 1980s, modern understanding of complete functional rehabilitation in orthognathic surgery was further enhanced.

Patients with clefts of lip, alveolus and palate or some facial syndromes need complex and long-lasting orthodontic therapy. The possibility of orthodontic anchorage is often limited by congenital absence of teeth, disturbed skeletal growth or failing compliance with extraoral sources of force. Correct positioning and insertion provided, miniscrews can serve as anchorages and shorten the period of active treatment in patients with clefts.
