Bone mass change and aesthetic outcomes in the upper anterior tooth area after immediate-delayed implantation

Abstract

Abstract:

BACKGROUND: A large amount of apicocoronal and buccolingual bone resorption occur in alveolar bone after tooth extraction, leading to the distinct shortage of bone mass of alveolar bone in tooth-missing area, which has a certain effect on the stability of early implantatiion and postoperative aesthetic outcomes and greatly affects the long-term success rate of denture implantation. Therefore, immediate-delayed implantation can shorten the time of repair.
OBJECTIVE: To evaluate the effect of implant repair after immediate-delayed implantation and application of guided bone regeneration technique in anterior maxilla area.
METHODS: Nineteen patients (28 teeth lost) with maxillary anterior tooth loss and labial one-walled bone defects were selected. Twenty-eight OSSTEM implants were implanted at 4 weeks after tooth extraction. Guided bone regeneration technique was applied concurrently in labial bone defect area. The secondary repair was performed after 6 months.
RESULTS AND CONCLUSION: The success rate of these 28 implants was 100% at 24 months after denture implantation. The peri-implant bone height loss at 6, 12 and 24 months was 0.1, 0.6 and 0.11 mm, respectively. Red aesthetic scores were satisfactory. Immediate-delayed implantation combined with application of guided bone regeneration technique for treatment of maxillary anterior tooth loss and mild bone defect can restore the height and width of peri-implant bone and acquire stable vertical bone resorption and satisfactory gingival aesthetic outcomes .
