Materials and Methods: The material comprised 628 final casts for RPDs. Each cast was photographed in a way that would allow the number of existing teeth, the classification of partial edentulism, the RPD support, and the particular parts of the metal framework to be identified. Data collected were analyzed statistically using prevalence tables and the χ2 test. Results: Two hundred seventy six (43.9%) casts were for the maxilla Selleckchem Panobinostat and 352 (56.1%) for the mandible. The most frequently encountered group was Kennedy class I for both arches, while class IV was the classification least encountered (p < 0.001). Of all RPDs constructed,
96.8% had a metal framework (tooth-borne and tooth/tissue-borne), while VX-809 clinical trial 3.2% of the RPDs were frameless (tissue-borne, acrylic dentures). The U-shaped palatal connector (horseshoe) in the maxilla
and the lingual bar in the mandible were the most frequently used for all partial edentulism classes, at 55.2% and 95%, respectively. Conclusions: Analysis of the casts revealed that the type of major connectors selected does not comply with the indications for their applications, considering the lack of dental history and clinical examination. This notes the need for further training dentists and dental technicians in aspects of RPD framework design. “
“Cleidocranial dysplasia (CCD) is a rare congenital disorder characterized by skeletal and dental anomalies. This clinical report describes the prosthodontic approach to treating MCE a CCD patient who presented with decreased facial height and relative mandibular protrusion due to maxillary hypoplasia after orthodontic treatment. Functional and esthetic rehabilitation was achieved using telescopic detachable prostheses in the maxilla and osseointegrated implants and metal-ceramic fixed dental prostheses in the mandible. These treatment approaches precluded the need for orthognathic surgical correction and presented a favorable prognosis during the 5-year observation period. Cleidocranial
dysplasia (CCD) is a rare autosomal-dominant skeletal dysplasia best known for its dental and clavicular abnormalities. The most characteristic feature of CCD is hypoplasia or aplasia of the clavicles, resulting in hypermobility of the shoulders. Patients with CCD tend to be of moderately short stature and have proportionally large heads with pronounced frontal and parietal bossing. A broad base of the nose with a depressed nasal bridge as well as ocular hypertelorism may also be observed. The face appears small in relation to the cranium due to the presence of hypoplastic maxillary, lacrimal, nasal, and zygomatic bones. Dental problems are a significant manifestation of CCD. Retained deciduous dentition, delayed eruption or retention of the permanent dentition, and multiple supernumerary teeth are common findings in CCD patients.
