Beskrivelse
Inclusion Criteria:
- Adult (>20 years) with nonrestorable maxillary teeth in the esthetic zone, thick gingival phenotype, intact but thin labial plate of bone extending 7 mm (≤1 mm) and intact palatal bone extending at least 6 mm apically, sufficient apical bone to attain implant primary stability (a minimum of 35 N cm insertion torque) and labio-palatal socket dimension measured from the CBCT axial cut at mid-crestal part ≥5 mm.
Exclusion Criteria:
- Smokers, pregnant women, patients with systemic disease, patients with parafunctional habits such as bruxism or clenching, infected socket, periapical pathosis and history of radiotherapy or chemotherapy within the past 2 years.

Aktiv komparator: IIP + Bone graft + CHA
For patients assigned to receive a graft, demineralized bovine bone graft (Bio-Oss, Geistlich Pharma AG, Wolhusen, Switzerland) was placed in the gap labial to the implant to the level of the implant platform.
|
A tapered screw-vent bone level implant (Zimmer implant TSV, IN, USA) was inserted into the extraction socket in a flapless manner, engaging 3-4 mm of the sound intact apical and palatal bone to achieve primary stability using the motor and manual torque wrench which was set to be at least 35 N cm to allow nonfunctional immediate loading.
The implant platform was located 1.5 mm subcrestal or equicrestal to the labial bone and the implant diameter was selected to leave a labial gap of at least 1.5 mm.
Following implant placement, randomization sequence with allocation to either graft or no graft group was revealed.

Eksperimentel: IIP + CHA only
A tapered screw-vent bone level implant (Zimmer implant TSV, IN, USA) was inserted into the extraction socket in a flapless manner, engaging mm of the sound intact apical and palatal bone to achieve primary stability using the motor and manual torque wrench which was set to be at least 35 N cm to allow nonfunctional immediate loading.
The implant platform was located 1.5 mm subcrestal or equicrestal to the labial bone and the implant diameter was selected to leave a labial gap of at least 1.5 mm.
Following implant placement, patients received an immediate anatomical customized healing abutment fabricated by adding flowable composite to the temporary cylindrical abutment mimicking the shape of the socket at the marginal gingiva (Filtek™ Supreme Ultra Flowable Restorative, 3M Corporate Headquarters, MN, USA).
It was then screwed to the implant
