General Guidelines for Using Dentapreg Strips in Laboratory

  • Dental stone model is a good training tool for trials of Dentapreg™
  • Avoid sharp edges and undercuts on the model
  • Before forming Dentapreg™ strip on a model, always apply separation liquid or wax
  • Always use the widest clinically acceptable Dentapreg™ strip
  • During forming and adaptation of the Dentapreg™ strip advance slowly from one end to the other to allow for a good adaptation of the fibrous reinforcement and small flow of the resin to avoid defects and shape memory effect
  • To minimize potential damage to the fibers, is rocemmended to use plastic instruments used to work with dental filling composites
  • When preparing the strip (measuring, trimming), keep the strip in it's original protection foils to avoid contamination
  • Avoid sharp edges and extremely small interproximal curvatures when forming Dentapreg™ strips to prevent fiber breakage
  • Adhere strictly to the acid etching and adhesive curing procedures recommended by the etching agent and adhesive manufacturers
  • Polishing or sand blasting of cured Dentapreg™ should be avoided, to enhance patient comfort and maintain good hygienic conditions, a layer of light curing hybrid composite can be deposited on the Dentapreg™ surface and polished using standard procedures
  • It is important to keep the working table clean to prevent metal or ceramic dust to stick to the surface of uncured Dentapreg™ strip
  • Standard step preparation of abutments should be used when making Dentapreg framework supported all composite fixed partial denture. The recommended depth of preparation is 1.2-1.5 mm on all aspects of axial surfaces. Occlusal isthmus approximately 1mm deep can be used in the case of posterior abutments. At least 1mm but preferably 1.5 to 2.0 mm of occlusal clearance is recommended
  • Pontic can be sculptured using common C&B composite or acrylic denture tooth can be used. Acrylic tooth can be bonded to the cured Dentapreg framework using light, self or heat curing composite. Denture base resin can also be used to bond acrylic tooth to Dentapreg framework, though it is less recommended
  • Dark abutments or endodontic posts can be covered with a standard opaquer before forming the Dentapreg™ strip
  • Possible undercuts on abutments can be covered with light colored wax
  • Standard dental wedges can be used to prevent flow of the composite into interproximal space during the initial stage of sculpting the prosthesis
  • Dentapreg should always be covered with at least 0.2 mm thick layer of light curing composite. In no case, Dentapreg should protrude into the surface of the prosthesis.
