BACKGROUND: Dental Prosthesis misfit in multiple implants is often encountered and can be corrected through impression techniques in producing an accurate, passively fitting prosthesis and ensuring maximum precision. Splinting multiple implants with a ridid and dimensionally stable can be a wise choice. Therefore, an in-vitro study was designed to compare the dimensional stability of Pattern resin and BD Impress as splinting material on the positional accuracy in multiple implants by open tray implant impression technique. AIM: The aim of the study was to evaluate and compare the positional accuracy in multiple implants by splinting with pattern resin and BD Impress. MATERIALS AND METHODS: An epoxy resin model was fabricated into which four implants were placed. The open tray copings were attached and splinting was done with pattern resin in Group I (n=6) and with BD Impress in Group II (n=6). Six open tray impressions were made with vinyl polysiloxane and analogs were attached. The casts retrieved from each group were analysed for the positional accuracy using Vision Measuring Machine (VMM). The mean values of all the measurements for each group were obtained and they were statistically analysed using unpaired t test at a significance of 0.5 using SPSS 22.0 software. RESULTS: The mean inter implant distance between the Group I and Group II showed that there was only marginal difference(P value ≤ 0.05) with positional accuracy in both Group I and Group II thus concluding that there was no comparable difference between Group I and Group II. CONCLUSION: Results showed BD Impress can be used as splinting material in multiple implant prosthesis, as both pattern resin and BD Impress exhibited similar positional accuracy in impression.
