The aim of this study was to analyze the dental implant treatment data at the Faculty of Dentistry, Chulalongkorn University (FDCU) for the past 5 years. The treatment records of patients who had implants placed during 2014-2018 were retrieved from the FDCU electronic patient database. Patient information; sex, age, region, implant number and complications, and patient’s follow-up were collected. The data were analyzed by descriptive statistics using IBM SPSS Statistics software.  We found that among 4,111 records, 2,734 records with 4,279 implants met the study criteria. The number of implant patients increased approximately 10 % each year. The average patients’ age was 55.9 years old (range 15-89 years). Sixty percent of the patients were 50 - 69 years old, female, and had one implant placed. Seventy-one percent of the implants were placed in the posterior region. Among the 1,967 patients who had complete implant restoration for at least six months, 1,245 (63.3 %) followed the maintenance recall schedule. Complications were detected in 288 implants and 76 implants were eliminated. Seven departments/clinics at FDCU provided implant treatment. However, missing implant details and illegible handwriting were found in many records. In conclusion, the number of dental patients at FDCU is increasing. Most patients were 50-69 years old, with the majority of the implants placed in the posterior region. Although half of the patients followed the first-year maintenance recall schedule, the number decreased over time. Few complications were noted. One third of the records was incomplete resulting in less data to be analyzed.
