ACTIVE_COMPARATOR: Technique I
Loading of a zinc polycarboxylate (with the requirements of ISO 9917) cement to fulfill the crown Cement: Poly-F, DentsplySirona, York, Pennsylvania, United States Mixing Ratio: 1 scoop powder: 2 drops liquid Mixing Time (extraoral): 30 seconds Working Time (extraoral): 45 seconds Application (extraoral): placement of mixture into crown using a heidemann Spatula Setting Time (intraoral): 2-8 minutes |
intraoral cementation of single-tooth implant crowns with three different technique, intraoral removal of cement excess upon setting
|
ACTIVE_COMPARATOR: Technique II
Loading of a zinc polycarboxylate (with the requirements of ISO 9917) to fill the coronal half of the crown Cement: Poly-F, DentsplySirona, York, Pennsylvania, United States Mixing Ratio: 1 scoop powder: 2 drops liquid Mixing Time (extraoral): 30 seconds Working Time (extraoral): 45 seconds Application (extraoral): placement of mixture into crown using a heidemann Spatula Setting Time (intraoral): 2-8 minutes |
intraoral cementation of single-tooth implant crowns with three different technique, intraoral removal of cement excess upon setting
|
ACTIVE_COMPARATOR: Technique III
Application of a zinc polycarboxylate (with the requirements of ISO 9917) to the axial walls of internal surface of crown Cement: Poly-F, DentsplySirona, York, Pennsylvania, United States Mixing Ratio: 1 scoop powder: 2 drops liquid Mixing Time (extraoral): 30 seconds Working Time (extraoral): 45 seconds Application (extraoral): application of mixture into crown using a bonding applicator tip Setting Time (intraoral): 2-8 minutes |
intraoral cementation of single-tooth implant crowns with three different technique, intraoral removal of cement excess upon setting

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
visual assessment of residual cement on crown-abutment complex
Time Frame: 15 minutes
|
removal of cemented crown-abutment complex to detect excess cement on the mesial, distal, buccal and lingual surfaces of crown and abutment separately scoring: presence or absence
|
15 minutes
|
measurement of residual cement area and distribution
Time Frame: 30 minutes
|
digitalization of the removed crown-abutment complexes those scored with cement presence, then using a software, virtual selection of existing cement to calculate the area in millimeter square and to define the direction and the extension in millimeters on the mesial, distal, buccal and lingual surfaces of crown and abutment separately
|
30 minutes
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
visual assessment of residual cement around the peri-implant soft tissue
Time Frame: 15 minutes
|
removal of cemented crown-abutment complex to detect excess cement on the peri-implant soft tissue contacting the mesial, distal, buccal and lingual surfaces of crown-implant complex scoring: presence or absence
|
15 minutes
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
correlation of abutment margin and crown-abutment contour with 'Outcome 2' measures
Time Frame: 30 minutes
|
Recording of stock abutment margin location at mesial, distal, buccal and lingual surfaces in relation to peri-implant soft tissue level measurement in millimeters Defining of abutment to crown transition angle at mesial, distal, buccal and lingual surfaces description as concave, convex or flat |
30 minutes
|
recognition of residual cement on radiographs
Time Frame: 20 minutes
|
evaluation of peri-apical radiographs of cemented crowns to detect presence of excess cement on mesial and distal surfaces scoring: presence or absence
|
20 minutes
