In each patient (unilateral or bilateral mandible), one of the implants was placed with submerged procedure and in the other one non- submerged procedure was used. In a period of 3 months a temporary partial denture that covered the implants was used. After 3 months the submerged fixture was exposed, impression was performed and fixed prosthesis was fabricated. Loss of crestal bone at each implant was measured. These measurements have been done at surgical times, over a period of 3 months after implant installation and 6 months after the delivery of the fixed prosthesis. The measurement was done with digital subtraction radiography. Data was analyzed by Wilcoxon Signed Ranks test.</span></span></span></p><p style="TEXT-ALIGN: justify MARGIN: 0cm 0cm 0pt" class="null"><span style="FONT-FAMILY: Times New Roman"><strong><span style="FONT-SIZE: 10.5pt mso-bidi-font-family: 'B Mitra'">Results:</span></strong><span style="FONT-SIZE: 10.5pt mso-bidi-font-family: 'B Mitra'"> <span style="COLOR: black"><span style="FONT-FAMILY: COLOR: black FONT-SIZE: 10.5pt">Three months after implant placement, submerged groups showed statistically more crestal bone loss (0.65±0.71) than non-submerged (0.41±0.53) group (p=0.02). </span><span style="FONT-FAMILY: FONT-SIZE: 10.5pt">After 6 months the mean value of crestal bone loss in submerged group was <span style="COLOR: black">0.21±0.40 mm</span> and in non submerged group was <span style="COLOR: black">0.29±0.49 mm</span>.
