1/52. Prosthetic reconstruction in the cleft lip and palate patient with an extracoronal resilient attachment retained removable partial overdenture: case report.There are still some difficulties in prosthetic reconstruction of cleft lip and palate patients with conventional prostheses or implant retained prostheses. The most common difficulties are insufficient alveolar bone quality and quantity, inadequate soft tissue, and abutment teeth. The patient we report on was a 23-year-old man with a clinical diagnosis of right incomplete cleft lip and palate combined with midface dysplasia. The maxillary six anterior teeth were reconstructed. The maxillary right central incisor and canine were used as abutments for an extracoronal resilient attachment (ERA) retained removable partial overdenture. The STERN ERA SYSTEM is a hinged resilient attachment with an ideal stress breaking characteristic, a good retentive function, and easy chairside replacement. The 2-year follow-up examination revealed an adequate esthetic appearance with good retention and stability of the prosthesis. A removable partial overdenture using the teeth adjacent to the cleft area as abutments with an adequate attachment design is an alternative method for prosthetic reconstruction of cleft lip and palate deformity.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
2/52. Biomechanical considerations in distraction of the osteotomized dentomaxillary complex.The completely osteotomized dentomaxillary complex is essentially a free body constrained only by its soft tissue attachments. Therefore the line of action and point of application of any protractive force(s) used during distraction osteogenesis must be considered relative to its center of mass. This is in contrast to the nonsurgically separated dentomaxillary complex, which is a constrained body, and therefore the application of protractive force(s) must be considered relative to its center of resistance. These two centers are not coincident. With knowledge of the location of the center of mass, predictable protraction of the dentomaxillary complex can be achieved. In this study, the center of mass of an adult maxillary specimen osteotomized to emulate a Le Fort I osteotomy was determined. Protractive force(s) through the center of mass will produce linear advancement along its line of action. Protractive movement of the dentomaxillary complex can be adjusted downward and forward or upward and forward by locating the protractive force(s) line of action superior or inferior to the center of mass. A cleft patient is described wherein the surgically separated dentomaxillary complex is protracted downward and forward with a force vector superior to its approximate center of mass. This results in a predictable increase in overbite and overjet with negligible mandibular rotation.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
3/52. Midface distraction osteogenesis in cleft patients: a case report.We present a case of midface distraction in a bilateral cleft lip and palate patient. The patient was a 10-year-old who underwent a high LeFort I osteotomy followed by placement of the Rigid External Distraction halo. Distraction was commenced on the fifth postoperative day at a rate of 1 to 1.5 mm per day until a total of 17 mm of maxillary advancement had been achieved. There were no complications and follow up was at 9 months post distraction. Results show that the patient had improved facial aesthetics and dental occlusion which was overcorrected to a Class III relationship. Velopharyngeal function was unaffected. Distraction osteogenesis of the midfacial skeleton in cleft patients offers the possibility to remodel not only the underlying bony skeleton but also all the soft tissues of the face and palate.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
4/52. Popliteal pterygium syndrome in a Swedish family--clinical findings and genetic analysis with the van der Woude syndrome locus at 1q32-q41.The present study describes a Swedish family in which the mother and her son were affected with signs of popliteal pterygium syndrome (PPS, OMIM 119500). Both individuals had bilateral complete cleft lip and palate, oral synechiae, paramedian pits on the lower lip, toe syndactyly and a piece of triangular skin overgrowth on the great toes. The son also presented with soft tissue syndactyly of the 2nd and 3rd fingers. Although popliteal pterygium was not found, the above clinical features were diagnostic for PPS. Chromosomal abnormalities were not revealed in either case by cytogenetic analyses. A test for microdeletion in the VWS region at 1q32-q41 was performed in the family using 5 polymorphic microsatellite markers from the region. The affected son was found to be heterozygous for all 5 markers, suggesting that microdeletion at the VWS region was unlikely. The VWS locus, however, was not excluded by haplotype analysis of the family.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
5/52. 4p- syndrome and 9p tetrasomy mosaicism with cleft lip and palate.Chromosome 4p- syndrome is a multiple malformation syndrome associated with partial deletion of the short arm of chromosome 4 (4p-). It is characterized by dysmorphic features and retarded development. cleft lip and/or palate are the major clinical manifestations. Cases of tetrasomy 9p are extremely rare; the principal clinical manifestations of this condition are characteristic craniofacial abnormalities, generalized hypotonia and severe mental retardation. We present the first case of a female infant with 4p deletion and tetrasomy 9p mosaicism, exhibiting a left-sided cleft lip, alveolus and soft palate. karyotype analysis of lymphocytes cultured from the patient revealed that she was mosaic: 86% of the cells were 46, XX, add (4) (p15.32) and 14% were 47, XX, add (4) (p15.32), idic (9)(q12). The G-banding pattern appeared consistent with either translocation or partial proximal deletion of 4p. In order to make a definitive cytogenetic diagnosis of isodicentric chromosome 9, fluorescence in situ hybridization (FISH) was applied. At 8 months, when the patient weighed 4.3 kg, her cleft lip was repaired. Before and after surgery there were no seizures, and the postoperative course was uneventful.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
6/52. Dermal thymus: case report and review of the literature.An aberrant thymus is not uncommon; it is usually located in the subcutaneous tissue and attaches to deeper structures, but it rarely occurs within the dermis (dermal thymus). We report on an 8-month-old male infant with a dermal thymus. He was born with a skin tumor on the right side of the neck, located just over the sternocleidomastoid muscle. The tumor was soft, dark red, and elevated. It measured 10 by 21 mm in diameter. The surface was erosive and partially covered with crust. The infant also had a unilateral cleft lip and a deformity of the bilateral auricles. Because of recurrent episodes of infection, the tumor was resected and histologically diagnosed as a dermal thymus.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
7/52. suggestion for orthodontic and speech improving measures in CLP patients.The objective of the present paper is to describe a soft palate level device, the veloretractor, which is a combination of orthodontic appliance and therapeutic aid in speech therapy. Its use is demonstrated in a case report of a child with complete bilateral cleft lip and palate. Both orthodontic and phoniatric/pedaudiologic treatment needs during the course are demonstrated along with the treatment results.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
8/52. Proboscis lateralis: radiological evaluation.Proboscis lateralis is a rare craniofacial anomaly. It consists of a soft, trunk-like process that originates from the medial portion of the orbital roof and it may be accompanied by a number of facial and cerebral anomalies. The characteristics and relationship of the lesion to adjacent structures should be known, and associated anomalies should be detected before surgical correction. The patient should undergo neuroimaging studies besides clinical evaluation to obtain this information in detail. The neuroimaging findings of only one previous case are available in the literature. We report two cases of proboscis lateralis evaluated by CT and MRI before corrective surgery.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
9/52. adolescent dentistry: multidisciplinary treatment for the cleft lip/palate patient.Congenital labiomaxillary clefts result from the absence or incomplete fusion of the maxillary and medial nasal processes with resultant hard and soft tissue defects. Comprehensive treatment of these defects requires the collaborative efforts of surgeons, orthodontists, restorative clinicians, and laboratory technicians. Precise periodontal and orthodontic treatments must be carefully coordinated with the restorative plan to ensure sufficient space and tissue architecture for the definitive restorations. This article describes the multidisciplinary treatment of a cleft lip/palate patient using conservative fixed and removable restorative options to provide aesthetic restoration.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
10/52. Syngnathia and Van der Woude syndrome: a case report and literature review.OBJECTIVE: Syngnathia is a rare anomaly involving soft tissue or bony adhesions between the maxilla and mandible. We review the literature and present a case of syngnathia associated with Van der Woude syndrome. Syngnathia can have very different etiologies, but this has rarely been reported in Van der Woude syndrome. Treatment of this condition is rarely discussed in the literature because of a paucity of case reports. RESULTS: Oral adhesion (syngnathia) in our patient was caused by a mandibular to maxillary fibrous band. Surgical treatment was successful. Clinical implications and review of literature for the treatment of this rare association of syngnathia and Van der Woude syndrome are discussed.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
