Abstract
A tear-resistant dental dam is provided. The tear-resistant dental dam includes a first elastomeric sheet and a second elastomeric sheet disposed on the first elastomeric sheet. The first and second elastomeric sheets have a grid pattern of weld joint regions configured to couple together the first and second elastomeric sheets. The grid pattern of weld joint regions define a plurality of unwelded regions of the first and second elastomeric sheets.
Claims21
A tear-resistant dental dam, comprising:
- a first elastomeric sheet;
- and
- a second elastomeric sheet disposed on the first elastomeric sheet, the first and second elastomeric sheets having a grid pattern of weld joint regions configured to couple together the first and second elastomeric sheets, the grid pattern of weld joint regions defining a plurality of unwelded regions of the first and second elastomeric sheets.
A tear-resistant dental dam, comprising:
- a first elastomeric sheet;
- and
- a second elastomeric sheet disposed on the first elastomeric sheet, the second elastomeric sheet having a plurality of apertures extending therethrough that define a grid pattern of elastomeric material of the second elastomeric sheet, the grid pattern of elastomeric material being coupled to the first elastomeric sheet.
A tear-resistant dental dam, comprising:
- an elastomeric sheet having a plurality of pocket regions defining a grid pattern of elastomeric material, a thickness of a portion of the elastomeric sheet underlying the plurality of pocket regions being less than a thickness of the grid pattern of elastomeric material.
