Abstract
AbstractObjectiveTo assess the clinical and radiographic outcomes of alveolar ridge augmentation using a novel three‐dimensional printed individualized titanium mesh (3D‐PITM) for guided bone regeneration (GBR).Materials and methodsPreoperative cone‐beam computed tomography (CBCT) was used to evaluate alveolar ridge defects, followed by augmentation with high‐porosity 3D‐PITM featuring circular and spindle‐shaped pores. Postoperative CBCT scans were taken immediately and after 6 months of healing. These scans were compared with preoperative scans to calculate changes in bone volume, height, and width, along with the corresponding resorption rates. A statistical analysis of the results was then conducted.ResultsA total of 21 patients participated in the study, involving alveolar ridge augmentation at 38 implant sites. After 6 months of healing, the average bone augmentation volume of 21 patients remained at 489.71 ± 252.53 mm3, with a resorption rate of 16.05% ± 8.07%. For 38 implant sites, the average vertical bone increment was 3.63 ± 2.29 mm, with a resorption rate of 17.55% ± 15.10%. The horizontal bone increment at the designed implant platform was 4.43 ± 1.85 mm, with a resorption rate of 25.26% ± 15.73%. The horizontal bone increment 2 mm below the platform was 5.50 ± 2.48 mm, with a resorption rate of 16.03% ± 9.57%. The main complication was exposure to 3D‐PITM, which occurred at a rate of 15.79%.ConclusionThe novel 3D‐PITM used in GBR resulted in predictable bone augmentation. Moderate over‐augmentation in the design, proper soft tissue management, and rigorous follow‐ups are beneficial for reducing the graft resorption and the incidence of exposure.
