SeaCure II Hi-Flow Model

SeaCure is a unique, moldable mouthpiece designed to precisely fit the individual diver’s mouth, teeth, gums and jaw configuration to provide maximum support of a regulator and, thus, eliminate jaw fatigue. The professional as well as the recreational diver will find SeaCure to be extremely well suited for all types of diving conditions. The newest model, the “Hi-Flow” offers an expanded port, which provides increased air flow. It also includes a new one piece molding and sealing attachment. This device allows for easier molding and is then used to protect the regulator from debris and unwelcome guests during storage. The Hi-Flow is available in clear, blue and black.
The Professional II – which is the original SeaCure model – is also available. It is used primarily to fit oversized orifice regulators.
Finding a mouthpiece that offers both unbeatable security and comfort has forever been the diver’s dilemma. SeaCure has been the definitive answer since 1992.

Customizing the SeaCURE Mouthpiece
As the customizing of the SeaCURE mouthpiece takes place before mounting on the regulator, please read all of the following instructions carefully and completely before proceeding.
Before beginning the molding process, assemble the following materials:
- 3-quart saucepan (at least 6" in diameter and 6" deep)
- Sharp pair of scissors
- Common kitchen tongs (optional)
- Mirror

Step 1

Unlike conventional mouthpieces, the SeaCURE mouthpiece must fit your mouth and jaw configuration precisely. Therefore, it has a specific top and bottom position. Most people's upper teeth are slightly forward of their lower teeth when the jaw is closed. (See Figure A).
If your bite is this way, the surface of the mouthpiece imprinted with the word "SeaCURE" (See Figure B) should be positioned facing upward, both in the molding process and in mounting the mouthpiece to your regulator.
However, some people's lower teeth extend in front of their upper teeth when the jaw is closed (See Figure C). If this is true for you, the SeaCURE imprinted surface of the mouthpiece should be positioned facing DOWNWARD (with "Pat. No." up) for both molding and mounting. Note: This positioning is very important for maximum comfort and effectiveness when diving!

Step 2

Having determined the proper positioning for your jaw, try your SeaCURE mouthpiece in your mouth just to get a feel for how it goes in. AT THIS POINT THE UNIT HAS NOT BEEN MOLDED AND WILL NOT YET FEEL COMFORTABLE. You will note that, unlike conventional mouthpieces, SeaCURE extends back to include all of your teeth. If the bite wing tips touch the back of your mouth behind the last teeth, take a sharp pair of scissors and trim off a small portion of each bite wing tip (See Figure D). Note: Cut off only about 1/8th inch of the tips at a time! Retry the mouthpiece in your mouth before trimming more! Trim only enough to clear the back of your mouth!

Step 3

In a three-quart saucepan (or a pan at least 6" in diameter and deep enough to hold 4" of water (See Figure E) fill with water to at least 4" depth. Bring water to a vigorous or rolling boil. Remove from heat and let water sit a few moments until the bubbling stops.

Step 4

Holding the mouthpiece with the attachment and with the bite tips pointed down, submerge the bite portion into the hot water up to the top of the bite piece area (See Figure F). DO NOT PUT THE REGULATOR END INTO THE WATER! DO NOT IMMERSE THE ENTIRE MOUTHPIECE! Hold the mouthpiece in this immersed position for 25 seconds( do not heat the mouthpiece beyond the recommended time); remove from water. SHAKE THREE TIMES TO REMOVE EXCESS WATER! Do not place the mouthpiece in your mouth if hot water remains on it.(With the water off of the mouthpiece, it is not too hot to put into your mouth.)

Step 5

Immediately place the SeaCURE mouthpiece in your mouth with the word "SeaCURE" properly positioned (See Step 1) and perform the following three steps together, working in front of a mirror to be sure the mouthpiece is centered under your nose:
1. BITE DOWN FIRMLY BUT D O NOT ATTEMPT TO BITE THROUGH THE MOUTHPIECE.
2. While setting your teeth, press the inner portion of the bite wings against the inside of your teeth with your tongue
3. At the same time, press the outer edges of the bite wings against your teeth and gums by pressing your fingers against your cheeks (See Fig G).

Relax, the SeaCURE mouthpiece is now custom-molded to your teeth and gums. The bite wings should have deep impressions of your teeth and should conform to your gums.
