Do not add water In several water. seconds it will develop into a creamy mix. Loading the Tray Rub the surface of the loaded tray material with water Note N t the th ttray material t i l iis loaded heaviest in the anterior section of the tray L di the Loading th Tray T Apply pp y a small amount of material on the initial loading of the tray. This allows the material to be pressed into the retentive holes of the tray After all the retentive holes have been engaged add the remaining material to the tray Making the Impression Begin injecting the material directly into the hamular notch area on one side of the arch Continue injecting (keeping the tip of the syringe imbedded into the material) up to the labial frenum and stop Making the Impression Inject into the hamular notch of the opposite side and continue f forward d to t the th labial l bi l frenum Making the Impression Inject some material to anterior hard palate area Note how the material “attaches (hydrophilic)” to the tissue and does not “drip drip (non-slumping)” (non-slumping) Taking the Impression Gently seat the tray in the patient’s mouth (do not overseat” As soon as material extrudes from the back of the tray “stop” seating Border Molding Gently hold the lower border of the upper lip and pull forward Have patient slowly open wide Border Molding Gently massage the right g and left cheeks of the patient Tray Removal Carefully remove the impression by breaking the seall att th the perpheral h lb borders d (Do not remove impression by y tugging gg g on the handle of the tray) Thoroughly rinse impression of saliva Tray Removal Disinfect Di i f t iimpression i using materials and techniques q appropriate pp p for irreversible hydrocolloid materials Support the impression using the Accu-dent tray holder (do not lay impression on counter) t ) Final Impression Note the accuracy of the peripheral border registrations Final Impression In particular note the detailed registration of the hamular notch area Border molded final maxillary impression Impressions for the mandibular dib l edentulous d t l arch h The mandibular Accu Accu-dent dent impression is not a border molded like the maxillary impression The intent of the mandibular impression is to obtain a “fully extended impression” to facilitate the identification of the o t ea anatomical ato ca landmarks a d a s tthat at will gu guide de tthe e out outline eo of the denture border extensions Tray Selection (distal rise) Moderately resorbed ridges gradually incline to the ramus This gradual incline (low distal rise) is reflected in the mandibular trays #25-29 Tray Selection (distal rise) Severely resorbed ridges have a more abrupt incline to the ramus This high distal rise is reflected in the mandibular trays #20-24 T Tray Selection S l ti (size) ( i ) The “tray selection tool” f ilit t the facilitates th proper size i selection for the mandibular impression p tray y Measure approximately where the first molars are located on patients existing denture or on their ridge and select a tray that lines up to the center of the retentive holes of the tray Making the Impression The syringe gel material is fi t iinjected first j t d first fi t over th the retromolar pad area and than p pulled forward up p to the midline area M ki the Making th Impression I i The opposite retromolar pad is covered and the material is pulled forward to meet the contra-lateral contra lateral side Insert the loaded tray asking the patient to place their tongue between the lingual flanges of the tray F ll extended Fully t d d mandibular dib l impression p Fully extended mandibular impression options If the anatomy is accurately identified and marked this impression can serve as the th final fi l impression i i Fully extended mandibular impression options ….or this impression p can serve as preliminary impression for the fabrication of a custom impression tray Fully extended mandibular impression options ….or this impression can serve to fabricate a interim denture that will be functionally y relined several weeks after delivery
