Adjunctive Systemic Metronidazole to Nonsurgical Therapy of Peri-implantitis with Intrabony Defects: A Retrospective Case Series Study.

Purpose: To show the clinical and radiographic results of intrabony peri-implantitis lesions treated nonsurgically with adjunctive systemic metronidazole with a mean follow-up of 50 months.

Materials And Methods: Subjects diagnosed with peri-implantitis (probing depth ≥ 5 mm with concomitant bleeding on probing and/or suppuration) with radiographic evidence of intrabony defects > 2 mm were included in this study. Implants affected received one session of nonsurgical mechanical debridement with ultrasonic and steel curettes.

Influence of abutment height and implant depth position on interproximal peri-implant bone in sites with thin mucosa: A 1-year randomized clinical trial.

Objectives: The aim of this RCT was to assess radiographically the effect of abutment height and depth of placement of platform-switched implants on interproximal peri-implant bone loss (IPBL) in patients with thin peri-implant mucosa.

Material And Methods: Thirty-three patients received one prosthesis supported by two implants replacing at least two adjacent missing teeth (66 implants). Patients were randomly allocated and implant insertion depth adapted to abutment height groups (3 mm height group the implants were placed 2 mm subcrestally; 1 mm height group, equicrestally).

Effect of abutment height on interproximal implant bone level in the early healing: A randomized clinical trial.

Objective: The aim of this randomized clinical trial was to compare the effect on the interproximal implant bone loss (IBL) of two different heights (1 and 3 mm) of definitive abutments placed at bone level implants with a platform switched design.

Material And Methods: Twenty-two patients received forty-four implants (6.5-10 mm length and 3.

Influence of Abutment Height on Maintenance of Peri-implant Crestal Bone at Bone-Level Implants: A 3-Year Follow-up Study.

In this 3-year follow-up study, peri-implant bone loss at bone-level implants was evaluated with two definitive abutment heights: 1 mm and 2.5 mm. Peri-implant bone loss was defined as the distance between the implant shoulder and the first bone-to-implant contact from the time of loading to the 36-month follow-up, estimated using periapical radiographs.
