Posterior single implants immediately loaded using one abutment at one time and temporary abutment in the posterior mandible without bone augmentation: A report on six-month outcomes data obtained from a prospective randomized controlled split-mouth clinical trial
Background/Aim. Given that frequent manipulation of the abutment during immediate loading can have a negative impact on the surrounding peri-implant hard and soft tissues, the concept “one abutment at one time” (OAO) has been introduced and documented in daily clinical practice. The aim of...

| description | Background/Aim. Given that frequent manipulation of the abutment during
immediate loading can have a negative impact on the surrounding peri-implant
hard and soft tissues, the concept “one abutment at one time” (OAO) has been
introduced and documented in daily clinical practice. The aim of the study
was to evaluate changes in peri-implant bone levels, clinical and
radiographic parameters, and patient perspectives during the six-month
follow-up period. Methods. The study was designed as a randomized controlled
clinical trial. Patients with bilaterally healed sites in the posterior
mandible received implants with a diameter of no less than 3.5 mm and a
length of at least 8 mm. Based on randomization, patients were divided into
a test group and a control group. Patients who were in the test group
received implants that were immediately loaded with definitive abutments. In
contrast, patients in the control group received implants where healing
abutments were placed, followed by temporary abutments. Implants were
immediately loaded with provisional restorations within the first seven
days. They were delivered over the test group’s definitive abutment and the
control group’s temporary abutment. Probing depth, bleeding on probing,
clinical attachment level, plaque index, and keratinized tissue width were
measured. Patient-Reported Outcome Measures and the Oral Health Impact
Profile - 19 (OHIP-19) questionnaires were noted. Results. Out of 24
included patients, 22 completed the six-month follow-up. Peri-implant bone
loss between study groups was comparable (mesial: t = -0.798, df = 21, p =
0.434; distal: t = 1.688, df = 21, p = 0.106), without statistical
inter-group significance. OHIP-19 total scores significantly decreased after
three months and remained similar six months after the implant placement in
both groups without statistically relevant clinical inter-group changes.
Conclusion. The OAO approach and provisional abutments showed comparable
effectiveness regarding the immediate loading of posterior single implants. |
