Abstract

Objectives: To describe the clinical and radiographic characteristics of patients who received dental implants with micro-threaded neck design at the National Hospital of Odonto-Stomatology, Hanoi, between 2023 and 2024. Subjects and Methods: This descriptive case series study was conducted on 26 partially edentulous patients (over 18 years of age) at 34 implant sites, using ETK (France) implants at the Department of Implant Dentistry, National Hospital of Odonto-Stomatology, Hanoi. Clinical and radiographic characteristics were assessed, including: gender, age, location of tooth loss, cause and duration of tooth loss, available bone width and height, bone density, and thickness of keratinized mucosa. Results: A total of 26 patients were included in the study, with a higher proportion of females (53,8%). The mean age was 45,6 ± 9,6 years (range: 28-66), with the 35-50 age group comprising the majority (57,1%). The analysis of 34 edentulous sites indicated for ETK implants revealed the following: the primary cause of tooth loss was caries/endodontic pathology (97,1%), with periodontitis accounting for only 2,9%; no cases were due to trauma or congenital reasons. The duration of tooth loss was most commonly 6-12 months (41,2%). The available bone width was consistently >6 mm, with the 6-9 mm range being the most frequent (61,8%). The most common available bone height was 12-14 mm (38,2%), followed by >14 mm (35.3%). Bone density was predominantly D2 (61,8%) and D3 (38,2%), with the maxilla being mainly D3 (88,9%) and the mandible mainly D2 (80%). The thickness of the keratinized mucosa was ≥2 mm in the vast majority of cases (94,1%). Conclusion: The clinical and radiographic characteristics of the edentulous sites in the study cohort were favorable for the placement of ETK implants with micro-threaded neck design. This was demonstrated by adequate bone dimensions (width >6 mm, height >10 mm), good bone quality (predominantly D2 and D3 types), and sufficient keratinized mucosa thickness (≥2 mm) in most cases. Radiography is a crucial tool in implant placement.
