Case Report: A Predictable Technique to Establish Occlusal Contact in Extensive Direct Composite Resin Restorations: The DSO-Technique

Abstract

This paper describes the application technique of direct shaping by occlusion (DSO) for large composite restorations including the entire occlusal surface. For this technique, matrix bands and wedges are inserted without interference with antagonists in the desired occlusion. The final increment of soft-composite resin is shaped by letting the patient occlude on the uncured composite. Due to the nature of the technique, special care has to be taken for moisture control and handling of contamination. The procedure, advantages, and limitations of the technique are discussed.

“…Restaureringer i direkte plast kan placeres ved hjaelp af forskellige teknikker, som hjaelper med at danne den ønskede anatomi og okklusale relation. DSO-teknikken (Direct Sculpturing of Occlusion) (45,46) benytter silikonesammenbid til etablering af den øgede bidhøjde og placerer kompositplasten direkte, mens «Mold»-(36) og «Stamp»-(47) teknikkerne benytter en wax-upteknik på gipsmodel, ud fra hvilken en form kan fremstilles til applicering af plasten. Et eksempel på en fuldkaeberekonstruktion ved hjaelp af direkte plast er vist i figur 4.…”

“…Clinical use of direct particulate filler composites (PFCs) has been extended to large and cusp replacing restorations [1][2][3] , with satisfactory results 4) . Direct posterior PFC restorations fail predominantly as a result of fracture of the material, so called technical failure, either a superficial chipping or bulk (cohesive) material fracture.…”

“…In order to minimize the incidence of these failures, recommendations for placement techniques have been made 6) . From a purely technical procedure oriented perspective 2,3,7) , progress has expanded towards restorative techniques utilizing combinations of restorative materials in order to enhance the endurance of large direct PFC restorations and prevent catastrophic fractures.…”

Tratamento conservador em reabilitação oral através da interação entre Odontologia Restauradora e Prótese Dentária

“…A ideia de aumentar a dimensão vertical de oclusão foi descrita por Dhal 3,4 , visando melhora na função, na estética, redução da hipersensibilidade térmica e diminuindo a possibilidades de abrasão da estrutura dentária 5,6 . Neste contexto, várias técnicas usando restaurações diretas ou indiretas de compósitos em resina, cerâmica ou materiais híbridos foram descritas para a reconstrução de dentes desgastados e o restabelecimento da oclusão [7][8][9][10][11][12][13] . Os conceitos tradicionalmente reconstrutivos incluem principalmente coroas de porcelana fundida ao metal ou sobreposições de cerâmica.…”
