Facial clefting is one of the most common birth defects and having a child born with this defect can be a devastating experience for parents and family members. Until recently, repair of cleft lip and palate deformities was deferred until the infant had reached 10 weeks of age, 10 pounds in weight, and a hemoglobin level of 10 gm per 100 mL. This criteria eliminated neonates 28 days of age or younger from the possibility of early repair. Waiting until these criteria were achieved often caused problems with parent-infant bonding and infant growth and development. Advances in neonatology and pediatric anesthesia now have made it possible to perform cleft surgery during the neonatal period. This article discusses the anatomy and embryology of cleft deformities and how cleft repair surgery now can be performed on the neonate.
The purpose of this multicentre randomized clinical trial was to analyse surgical and prosthetic aftercare and clinical implant performance of edentulous patients with implant-retained mandibular overdentures and of patients with conventional dentures, either or not after pre-prosthetic vestibuloplasty and deepening of the floor of the mouth. The evaluation period was 5 years. The implant systems evaluated were the IMZ implant system, the Brånemark implant system and the Transmandibular Implant system. The centre in Groningen had five groups (n=149) and the centre in Nijmegen had three groups (n=86). The evaluation comprised of surgical and prosthetic aftercare, together with clinical implant performance (CIP). The highest implant loss (29%) is found in the Transmandibular Implant group. All groups had prosthetic revisions and complications according to the CIP-scale. The majority of the patients in the endosseous implant groups were subject to minor complications. The CIP-score of the Transmandibular Implant group is significantly higher than the scores of the other groups, because of the high number of lost posts. In 26;1% of the patients in this group score 4 is given, which means failure of the implant system. From this study it can be concluded that the endosseous implant systems used in this study have less surgical aftercare and a better clinical implant performance than the Transmandibular Implant system and are therefore the systems of choice for the edentulous mandible.
