The novel features of the disclosure are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present inventive concept will be obtained by reference to the following detailed description that sets forth illustrative examples, in which the principles of the disclosure are utilized, and the accompanying drawings of which:
Examples and various features and advantageous details thereof are explained more fully with reference to the exemplary, and therefore non-limiting, examples illustrated in the accompanying drawings and detailed in the following description. Descriptions of known starting materials and processes can be omitted so as not to unnecessarily obscure the disclosure in detail. It should be understood, however, that the detailed description and the specific examples, while indicating the preferred examples, are given by way of illustration only and not by way of limitation. Various substitutions, modifications, additions and/or rearrangements within the spirit and/or scope of the underlying inventive concept will become apparent to those skilled in the art from this disclosure.
As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, product, article, or apparatus that comprises a list of elements is not necessarily limited only those elements but can include other elements not expressly listed or inherent to such process, process, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
The term substantially, as used herein, is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder.
Additionally, any examples or illustrations given herein are not to be regarded in any way as restrictions on, limits to, or express definitions of, any term or terms with which they are utilized. Instead these examples or illustrations are to be regarded as being described with respect to one particular example and as illustrative only. Those of ordinary skill in the art will appreciate that any term or terms with which these examples or illustrations are utilized encompass other examples as well as implementations and adaptations thereof which can or cannot be given therewith or elsewhere in the specification and all such examples are intended to be included within the scope of that term or terms. Language designating such non-limiting examples and illustrations includes, but is not limited to: “for example,” “embodiment,” “for instance,” “e.g.,” “In some examples,” and the like.
Although the terms first, second, etc. can be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present inventive concept.

While the present disclosure illustrates an evacuation dam drawn to dental applications, it is within the scope of the present disclosure to encompass medical procedures and/or medical settings that would benefit from a controlled field with laminar flow and evacuation. The evacuation dam can be positioned over a portion of dental patient's face and provide a directional flow to reduce and/or eliminate particulate distribution during a dental procedure. The evacuation dam and/or evacuation dam frame of the present disclosure can be formed via additive manufacturing (e.g. 3-D printing), injection molded, cast, extruded, and/or other process. The evacuation dam and/or evacuation dam frame can be formed of metals, alloys, plastics, rubber, resins, fiber boards, combinations thereof, and/or similar materials having suitable rigidity to maintain the evacuation dam and/or evacuation dam frame.
The evacuation dam and/or evacuation dam frame can be disposable for each patient and/or the evacuation dam and/or evacuation dam frame can be reusable and sterilized between patients using one or more of cleaning solutions and/or ultraviolet light sources.
