CLINICAL CHARACTERISTICS AND EVALUATION OF TREATMENT OUTCOMES OF TOOTH LOSS OF MAXILLARY INCISOR USING SINGLE-WING ZIRCONIA DENTAL BRIDGES AT HO CHI MINH CITY ODONTO-STOMATOLOGY HOSPITAL
Main Article Content
Abstract
Background: In recent years, dental restoration technology has made significant advancements with various methods such as dental bridges, removable dentures, and implants, particularly the use of zirconia in dental bridges. Objective: To describe the clinical characteristics and evaluate the treatment outcomes of maxillary incisor tooth loss using a one-wing zirconia adhesive bridge at the Ho Chi Minh City Hospital of Odonto-Stomatology from June 2023 to February 2024. Materials and methods: A cross-sectional descriptive study on 32 patients with missing or absent maxillary incisors indicated for treatment with a one-wing zirconia adhesive bridge. Results: The highest recovery rates were for 21 and 12 teeth, accounting for 37.5% and 31.3%, respectively. The 11 and 22 teeth had equivalent rates of 15.6%. The causes of tooth loss due to accidents, caries, and other reasons were highest in patients aged ≥ 60, with rates of 40%,
58.3%, and 100%, respectively. The PI and GI index scores of 3 had the highest rate at 34.4%.
Treatment outcome evaluation showed that most patients achieved high satisfaction regarding restoration color, anatomical shape, adjacent tooth contact, and occlusal contact, with over 90% rated A according to the USPHS scale. No patients were recorded at levels C and D. Conclusion: The rate of maxillary tooth loss was quite high in older adults, particularly in teeth 21 and 12, with dental caries being the main cause. The results of treatment with a one-wing zirconia adhesive dental bridge showed high patient satisfaction regarding color, shape, proximal contact, and occlusion, with the majority achieving an "A" rating on the USPHS scale.
