Alteration of Keratinized Mucosa Dimensions in the Early Healing Period After Implant Placement: A 6-Month Prospective Study.

Purpose: To assess the alteration in keratinized mucosa (KM) dimensions during the early healing period after implant placement and the influence of the variables measured during implant surgery on KM alteration.

Materials And Methods: The study participants were consecutively recruited from patients who had received implants following a nonsubmerged surgical protocol. The implant had to be placed in an extraction socket that had healed for more than 6 months without any soft or hard tissue augmentation.

Prevalence and risk indicators of peri-implantitis in Korean patients with a history of periodontal disease: a cross-sectional study.

Purpose: The aim of this study was to analyze the prevalence and risk indicators of peri-implantitis in Korean patients with history of periodontal disease.

Methods: A total of 444 patients with 1,485 implants were selected from patients who had been treated at the Department of Periodontology, Chonbuk National University Dental Hospital between July 2014 and June 2015. A group with a history of peri-implantitis (HP) (370 patients with 1,189 implants) and a group with a current peri-implantitis (CP) (318 patients with 1,004 implants) were created based on the radiographic and clinical assessments of implants.
