Abstract

Background: Mandibular molar loss is often accompanied by hard- and soft-tissue resorption, which may adversely affect the long-term outcomes of dental implant treatment. Increasing peri-implant soft-tissue volume may contribute to the long-term stability of implant therapy. Objectives: To describe the clinical characteristics and cone-beam computed tomography findings in patients with mandibular molar loss who were indicated for dental implant placement combined with soft-tissue augmentation using the tent-pole technique or xenogeneic soft-tissue grafting at Can Tho University of Medicine and Pharmacy Hospital. Materials and methods:  A cross-sectional descriptive study was conducted on 30 patients with 40 mandibular molar edentulous sites indicated for dental implant placement combined with soft-tissue augmentation using either the tent-pole technique or xenogeneic grafting at Can Tho University of Medicine and Pharmacy Hospital from March 2024 to March 2026. Results: In the study sample, patients aged 18–39 years accounted for 86.7%. The main cause of tooth loss was dental caries and complications of pulpal disease, accounting for 87.5%. Most missing teeth were mandibular first molars, including tooth 36 in 37.5% and tooth 46 in 40.0% of the sites. The mean soft-tissue height ranged from 2.04 to 2.90 mm. On cone-beam computed tomography, the mean bone height was greater than 14.37 mm, and the mean buccolingual ridge width was greater than 6.86 mm. Bone density was predominantly classified as D3 (52.5%) and D2 (22.5%). Conclusion: In the study sample, mandibular first molar loss was more common than mandibular second molar loss, with dental caries and pulpal disease being the main causes. D2 and D3 bone densities were common, and the bone dimensions and soft-tissue height were suitable for dental implant placement combined with either the tent-pole technique or xenogeneic soft-tissue grafting.
