Objectives: The aim of the present case series is to exhibit the long-term clinical and radiographic outcomes of resective surgery with adjunctive implantoplasty over a 6-to-11-year follow-up.
Materials and methods: Four patients presenting 4 implants diagnosed with peri-implantitis according a to an established case definition were included in the present case series. Subjects underwent resective surgery, a modified implantoplasty approach, and implant surface decontamination. Clinical and radiographic outcomes such as bleeding on probing (BOP), suppuration on probing (SoP), probing depth (PD), marginal recession (MR), modified plaque index (mPI), and marginal bone levels (MBL) were recorded over a long-term following surgical therapy.
Results: Over 6-to-11-year follow-up, mean BOP, PD, and SoP scores amounted to 17 ±24%, 2.5 ±1.26 mm, and 0%, respectively. BOP scores were reduced in 17%, PD values in 2.5mm, and SoP scores in 100%. Radiographic analysis revealed a mean radiographic bone gain of 3.1 ± 1.84 mm. Peri-implant marginal bone loss surface area decreased by 5.7±3.77mm2 over the long-term follow-up.
Conclusion: Resective therapy with adjunctive implantoplasty promoted favorable clinical and radiographic outcomes at peri-implantitis treated sites over a long-term period.
Clinical relevance: Diverse surgical approaches such as resective, reconstructive, and combined therapy have been proposed towards peri-implantitis treatment. A resective surgical approach with an adjunctive "modified" implantoplasty refers to the modification of the implant body into a constricted area to mimic a "waist" silhouette. This modified technique conforms an adequate concave smooth area that may favor the outcomes of resective surgical therapy for soft tissue adaptation, biofilm control, and possible peri-implant bone gain over the long term.
