Eksperimentel: Resective surgery with implantoplasty
Full-thickness mucoperiosteal flaps will be elevated, and granulation tissue will be removed using surgical curettes.
The implant surface will be cleaned using mechanical debridement with titanium curettes and ultrasonic instruments.
In the test group, implantoplasty will be performed using rotary instruments to smooth and reduce implant surface roughness.
All implant surfaces will be irrigated with sterile saline before suturing.
Flaps will then be repositioned and secured using single interrupted sutures.
|
In the implantoplasty group, exposed implant surfaces not covered by bone will be mechanically smoothed using a resective approach aimed at reducing surface roughness.
No osteoplasty will be performed.
Implantoplasty will be carried out using oval-shaped tungsten carbide burs of progressively increasing diameter mounted on a rotary handpiece.
Surface refinement will then be completed using white Arkansas stone burs, followed by polishing with brown and green silica polishing burs under copious saline irrigation.
The implantoplasty procedure will be standardized to approximately 5 minutes per implant.

Aktiv komparator: Resective surgery with mechanical debridement
Full-thickness mucoperiosteal flaps will be elevated, and granulation tissue will be removed using surgical curettes.
The implant surface will be cleaned using mechanical debridement with titanium curettes and ultrasonic instruments.
In the control group, air polishing will be performed using the Airflow Prophylaxis Master with AIR-FLOW powder PLUS containing erythritol (14 µm), amorphous silica, and 0.3% chlorhexidine.
All implant surfaces will be irrigated with sterile saline before suturing.
Flaps will then be repositioned and secured using single interrupted sutures.
|
In the mechanical debridement group, visible calculus will be removed using an ultrasonic tip without direct contact with the implant surface.
Implant surfaces will then be decontaminated using the Airflow Prophylaxis Master device with erythritol (14 μm), amorphous silica, and 0.3% chlorhexidine.
The device will be operated at a static pressure of 5 bar with maximal water irrigation.
No implantoplasty will be performed.

|
Procentdel af steder med blødning ved sondering (procent)
Tidsramme: Ved baseline og 3 måneder efter operationen.

|
|
Modified Plaque Index (mPI) (score on a scale, 0-3; higher score = worse outcome)
Tidsramme: Baseline and 3 months post-surgery
|
Plaque accumulation will be assessed using the Modified Plaque Index (mPI) for dental implants, a 4-point ordinal scale where 0 = no detection of plaque / no visible plaque, 1 = plaque only recognized by running a probe across the marginal surface, 2 = plaque can be seen by the naked eye (>25%), and 3 = abundance of soft matter.
Scores range from 0 (minimum, best outcome) to 3 (maximum, worst outcome).
Higher scores indicate greater plaque accumulation.
Results will be summarized as the mean score per implant across the 6 sites assessed.
