_08 light_20 Materials and Methods Within the group of patients, which were treated for single-tooth replacement with FRIALIT ® implants, 104 patients (54 women; 50 men) with 120 implants were randomly and retrospectively selected for examination of the mesial and distal interproximal implant-tooth sites. The initial implant placement was performed according to the recommended surgical technique first published by Schulte and Heimke. A two-stage surgical technique was employed. All implants were restored with single implant-supported crowns. The mean interval between implant placement and evaluation of the restored inter- proximal implant-tooth site was 26 months (max. 83 months; min. 6 months). A total of 240 interproximal sites were measured: 150 (62.5%) in the maxilla, 90 (37.5%) in the mandible , of which 94 (39%) anterior interproximal, 96 (40%) pre-molar-interproximal, and 50 (21%) molar sites. The presence or absence of the interproximal papilla was determined visually prior to probing. If no space was visible apically to the contact point, the papilla was deemed to be present. In cases of a partially or fully open inter- proximal space, the papilla was deemed to be not present. The contact point was determined by dental floss and marked. A standardized periodontal probe (PCB 11, HU-Friedy) was used for measurements. The probe was inserted vertically on the mesial and distal aspect of the evaluated implant, until the crest of bone was probed. The vertical distance from the contact point to the crest of bone was measured and rounded off to the nearest millimeter. All values (n=240) were divided in four groups: < 3 mm, 3-6 mm, 6-9 mm, and > 9 mm. The evaluation of the presence or absence of the papilla, depending on the time of implant placement, was based on the following classifications: � Immediate implant placement: At time of tooth loss or extraction (within 1 week) � Delayed immediate implant placement: Epithelial covering of extraction site (within 9 months)

� Late implant placement: Complete osseous healing of extraction site (after 9 months). According to this classification, 16 implants were placed immediately after tooth loss or extraction, 45 implants were placed delayed immediate and 59 implants were placed late. The horizontal distance between the single implant and the adjacent tooth was evaluated by panoramic radiographs (Siemens Orthophos). Technique-specific magnification factors were taken into account. The reference points for horizontal measurements were the uppermost edge of the FRIALIT ® implant and the CEJ of the adjacent tooth. All values (n = 240) were likewise divided into four groups: < 1 mm, 1-2 mm, 2-3 mm, and > 3 mm. Table 1: Influence of vertical height of dento-implant space on presence or absence of papilla In cases where the vertical distance was 3 to 6 mm, from the base of the con- tact point to the crest of bone, the papilla was present 73% (n=105) of the time. The probability of papilla presence is decreasing with increasing dis- tance. In cases where the distance was measured 6 to 9 mm, the papilla was present in only 32% (n=81) of the time. Above 9 mm the papilla was missing. It is interesting to note that at a vertical distance below 3 mm, the papilla was present a little less than half of the time (48%, n=33). Table 2: Influence of horizontal width of dento-implant space on presence or absence of papilla In cases where the horizontal distance between the uppermost edge of the implant and the CEJ of the adjacent tooth was 1 mm or less, the papilla was present in 37% (n=27) of the time. In cases of 1 to 2 mm the papilla was pre- sent in 65% (n=98) of the time and in cases of 2 to 3 mm in 51% (n=45) of the time. At a horizontal distance of 3 mm or more a papilla developed only in 17% (n=70) of the time. Table 1.
