A perfect match is rarely needed to satisfy the patient. Usually a slight mismatch is easier to manage and detect.  \nStep 2: Isolation  \nRubber dam is absolutely necessary if you work alone or you have a difficult isolation problem. Adhesive materials do not work if Blood or Saliva contaminate the field before the restoration is completely placed. I often use cotton rolls and work fast because I have the use of an assistant.  \nStep 3: Tooth Preparation  \nPrewedging: a useful and simple technique that helps prevent adjacent tooth damage (occurs 60-100% of the time) and aids in establishing tight contacts.  \nSlot preps: adjacent tooth damage is particularly a problem with small initial proximal preparations were contact may be maintained. A steel matrix can help protect the adjacent tooth if needed. You should be able to prepare a slot while maintaining a thin section of enamel and then break the enamel away. Remove unsupported enamel with spoon, hatchet or diamond bur. Breaking contact is not necessary and makes reestablishing contacts easier. Mechanical retention in the slot is important even with adhesive materials. This is especially important the more posterior the restored proximal surface is. These ridges take some heavy loads during chewing.  \nBevels: No bevels on the occlusal surfaces. We teach a conventional amalgam preparation with no bevels. Proximal bevels are optional  \nCheck adjacent Teeth: to evaluate for existing caries or damage from preparation. If a small carious lesion is detected it is easily repaired at this time without a slot prep. Smooth any adjacent tooth damage with a finishing bur at least  \nStep 4: Clean Tooth: Pumice  \n(Preppies, Whipmix) and an occlusal bristle brush can be used. Some use Concepsis (Ultradent) scrub which is a clorohexadine. Clorohexadine has been shown to slow degradation of bonds.  \nStep 5: Pulp Protection and base:  \nCaOH (Dycal or like) for exposures otherwise use RMGI (Fujii2 LC) as a base. This seals extremely well, releases fluoride, minimizes or prevents sensitivity. If the base is internal and will not extend to the external proximal surfaces (ie open sandwich) then I place the base before the band. This allows me to flow it in, allow it to set and quickly refine prep prior to composite placement. In the case of re-restoration where there is a large volume of missing tooth, the base makes a good first layer. Do not overbase the preparation and minimize the composite thickness or the composite will be at some risk  \nOSU-Seghi-revised 17  \nof fracture. If the proximals are deep and I wish to have RMGI extend subgingival (Open Sandwich), I will place band prior to base application. A RMGI liner (Vitrabond) can be used if there are isolated deep areas.  \nStep 6: Place matrix band or like.  \n2 surface : To get good consistently tight contacts, the ring type band (Palodent Plus, Dentsply or V3 Blue Disposable Ring Ultradent) seems to work better in dental students hands.  \n3 surface: we have thin dead soft Ho bands and prewedging. Wedging one side ata time during restoration can help also.  \nBurnish matrix: regardless of the matrix system, burnishing the matrix is key. If the matrix is not in contact with the tooth after wedging, there will be no contact.  \nStep 7: Open Sandwich:  \nUse RMGI (Fuji II LC) . Conventional GI (Ketac Fil) will not work. It washes out overtime to a greater extent. RMGIs seals extremely well, releases fluoride, minimizes or prevents sensitivity and acts as a good 1st layer to minimize composite volume. You can usually seal the gingival margin with a band adequate enough to prevent gingival leakage. The dentin is conditioned with the conditioner, rinsed, and lightly dried. Remember RMGI like moist dentin not dry dentin.
