Effectiveness of the palatal orthopedic appliance in treatment of the unilateral cleft lip and palate patientRobbins, Gregory A. January 1988 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Obturator therapy has been proposed for many years as an aid
in maxillary orthopedics for the complete unilateral cleft lip and
palate infant. The obturator appliance had the added benefit of providing
a false palate against which the infant can suckle. This has
aided in the feeding of these infants to assure adequate nutrition
with the least effort for parent and child. The current study
assessed three aspects of obturator therapy at James Whitcomb Riley
Hospital for Children, Indianapolis, Indiana.
Parental evaluations of the obturator proved to be very positive.
Almost all parents (96%) rated it as beneficial and would recommend
its use to other parents with cleft lip and palate infants. Weight
gain analysis over the first nine months of life demonstrated that
these infants were only slightly below the average for birth weight.
At three and nine months of age, a number (69% and 56% respectively)
had maintained their original weight percentile rankings or had just
dropped into the next lower category. Thus, many of the infants were
able to achieve adequate nutrition, a problem noted by many authors
when obturator therapy was not used. It should be emphasized that
each infant underwent either one or two major surgical procedures
during this time period.
Arch symmetry assessments at one, four and ten months showed
a gradual reduction in lateral posterior crossbite, canine crossbite,
and anterior crossbite tendency. Although the arches still showed
some collapse at the end of ten months of age, the pattern was much
better than at initial presentation with values much closer to normal.
Improvements in arch symmetry was expected as the maxilla grew.
From the results of this study, obturator therapy appears to be beneficial
in maxillary orthopedics by helping to maintain adequate weight
gain and gain parental acceptance.

Análise fotoelástica da tensão entre diferentes tipos de sistemas de retenção em próteses obturadoras palatinas implanto-retidas ou não e com ou sem reembasamento “soft”Ribeiro, Paula do Prado [UNESP] 13 April 2009 (has links) (PDF)

Perdas parciais ou totais de osso maxilar podem comprometer seriamente a fisiologia bucal causando sequelas como comunicações buconasosinosal. Neste caso, podese optar como forma de tratamento pela reabilitação protética com a aplicação de implantes osseointegrados. A literatura odontológica tem mostrado inúmeros trabalhos que avaliam a distribuição de forças com a finalidade de recolher melhores subsídios para o planejamento de próteses bucomaxilofaciais, que ainda é pouquíssimo explorada. Dentre os métodos utilizados, o da fotoelasticidade tem sido aceito, especialmente por permitir uma análise fiel da distribuição de forças. Assim, a proposta deste trabalho foi verificar a tendência de distribuição de forças e estresse, através do método fotoelástico, que incidem sobre diferentes tipos de sistemas de retenção em implantes (o’ring, barra clipe e o’ring/barra clipe) associado a próteses obturadoras palatinas implantoretidas e também em próteses obturadoras mucossuportadas (sem implante), utilizandose ou não de silicone com reembasamento direto (Sofreliner). O conjunto (prótese e modelo fotoelástico) foi posicionado em polariscópio circular e recebeu aplicação de carga de 100 N a velocidade de 10 mm/s no primeiro molar de cada prótese. Após as aplicações de carga houve a formação franjas correspondentes à tensão registrada. Então, as imagens foram transferidas para um computador e analisadas no programa ADOBE Photoshop. Ao se comparar os três sistemas de retenção das próteses obturadoras palatinas implantoretidas com a prótese mucossuportada (sem implantes), podese observar que as tensões foram distribuídas de forma mais homogênea... / The head and neck cancer is a very prevalent disease in Brazil and the main treatment is the surgery with or without radiation therapy and chemotherapy. Partial or total bone maxillary defects could involve seriously oral physiology causing consequences as buconasosinosal communications. In this case could be applied other option of treatment as prosthetic rehabilitation associated with osseointegrated implants. Scientific literature demonstrated countless studies that evaluate the force distribution with the aim to provide better subsidies for the planning of bucomaxillofacial prostheses, which still have few researches. Between the methodologies, the photoelastic method has been accepted; especially by allow an accurate analysis of the force distribution. Thus, the aim of this study was to verify the tendency of force distribution and the stress on different types of retention system (o’ring, clip bar and o’ring/clip bar) associated with palatal obturator prostheses with implant retention and conventional obturator prostheses (without implants), with or without silicone soft lining(Sofreliner), by means of photoelastic method. The set (prosthesis and photoelastic model) was located in circular polariscope and was applied a load of 100 load N at 10 mm/s on the first molar of each prostheses. After the load applications was registered the tension fringes. The images was transferred to a computer and analyzed at ADOBE Photoshop software. When compared the three retention systems of the palatal obturator prostheses and mucosupported prostheses (without implants), it can be observed that the stress was distributed more homogeneous and in lesser amount that the conventional prostheses, when compared to the other prostheses that presented implants and retention systems. With relation to stress distribution in the different retention systems, the bar clip... (Complete abstract click electronic access below)
