Sectional prosthesis with hollow obturator portion made of thin silicone layer over resin frame

Abstract: Magnetically retained sectional obturator prostheses, consisting of a hollow obturator portion made of thin silicone layer over a resin frame and a denture portion, were fabricated to alleviate some of the limitations of silicone materials, and applied to two edentulous patients with maxillectomy defects. The silicone obturator allowed profound engagement of undercuts within the defect, resulting in adequate retention, support and stability of the prostheses for over 3 years. The patients have achieved improve… Show more

“…Denture soft liners have been applied to the tissuefitting surface of hard denture bases for dual purposes: to act as shock absorbers for the denture-bearing mucosa 1) and to improve retention of the prosthesis 2) . Soft liners also allow the denture to move toward the implant heads and the edentulous areas, thereby distributing the masticatory forces more evenly to the implants and the edentulous ridge 3) .…”

“…Silicone relining material can be utilized to engage the undercut and it also relieves the pressure during function 20 . Here a portion of obturator was made resilient so that silicone material appropriately engages the undercut present to aid in relatively better retention and stability, which a rigid obturator fails to provide 21 . The portrayed obturator reduces the redundant load on the supporting tissue and meets the patient demands.…”

“…A prótese seccionada permite que pacientes com abertura bucal reduzida, possam colocar as suas peças com maior comodidade, porque a porção intra cavitária é posicionada em primeiro lugar e a porção da arcada dentária é posicionada, a seguir, fixando-se as duas através dos magnetos ou introduzindo-se a trava do ferrolho. (Figuras 2 e 3) [19][20][21][22][23] .…”

“…Encontramos técnicas, sobre: prótese seccionada com o bulbo tripartido; utilização de silicone, utilização de material termoplástico; utilização da abertura nasal como meio de retenção 2,17,20,[24][25][26] . Após levantamento realizado no LILACS, Bireme, Pubmed e na Scielo não encontramos nenhuma referência à PIGPM, que permitisse a comparação de um trabalho com outros autores.…”
