Impact of Implant and Site Characteristics on the Pattern of Bone Loss in Peri-implantitis.

Purpose: To assess the pattern of bone loss in peri-implantitis in partially edentulous patients and relate patient and implant/site characteristics that may influence such patterns.

Materials And Methods: In this retrospective study, the records of partially edentulous patients with dental implants were stratified according to sex, age, smoking, and diabetes. Implants were stratified according to site, number of years in function, presence of adjacent implants, diameter, bone-grafted site, and implant platform.

Comparison of Preprosthetic Implant Complications and Failures Between Obese and Nonobese Patients.

Purpose: Obesity as a systemic risk factor associated with implant failure or other complications has not been studied. The aim of this study was to compare the frequency of implant failure and complications between obese and nonobese patients.

Materials And Methods: Charts from 220 partially edentulous patients with 321 implants were examined for demographic information, medical health history, diabetes, smoking, patient-reported height and weight, periodontal status (no, mild, moderate, or severe periodontitis), tooth number, date of the implant and prosthesis placement, and treatment notes pertinent to the complications or failure.
