Abstract

Objective: To describe the clinical and radiological characteristics of a group of patients indicated for immediate implant placement in the posterior teeth using the Dual-zone technique at 225 Truong Chinh Dental Center - Hanoi Medical University. Subjects and methods: Research method is case series study design. The study subjects were patients whose posterior teeth in both jaws from the first premolar to the second molar were damaged and required immediate implant placement. Results: The study showed that the most common reasons for tooth extraction were tooth decay and pulp disease, accounting for 47.1%. The most common study subjects were aged 40-59, accounting for 52.9%. Bone density is mainly D3, accounting for 61.8%. The outer and inner bone plates in the molars are >1.5mm in size. The ratio of lower molars accounts for 58.8%, higher than the upper molars. The average distance from the sinus floor to the furcation area is 13.04 ± 3.85, the average distance from the inferior alveolar nerve canal to the furcation area is 16.34 ± 3.22. The average bone size in the maxillary area is 3.60, the mandibular area is 3.09. The inner root tip has the shortest distance from the sinus floor, the mesial root tip of the molars has the furthest distance from the inferior alveolar nerve canal. Conclusion: The anatomy of the maxillary and mandibular alveolar points both have suitable bone height for immediate implant placement. However, with small bone size and low bone density, it will be a challenge for clinicians to place implants in the correct position and achieve good initial stability.
