Abstract：
The ultimate goal in implantology is to restore the whole tooth-gingival complex in a fashion that cannot be distinguished from the rest of the natural dentition. This study assesses the volumetric and clinical changes in vestibular gingival soft tissues, crucial for satisfactory engraftment and esthetic results, upon treatment with laser-aided pouch roll augmentation in second-stage surgery for dental implant uncovering. Twelve patients with mild ridge deficiencies in 16 edentulous sites, including distal elements, were enrolled and reevaluated for up to 1 year. Digital impressions, taken with an intraoral laser scanner and software, were analyzed before (day 0) and after (month 12) treatment. The digital STL files were superimposed to assess volumetric and linear dimensional variations in selected peri-implant regions of interest by 3D analysis software. Clinical periodontal parameters (probing depth [PD], bleeding on probing [BoP], plaque index [PI]) and subjective patient-reported outcomes were also evaluated. In all patients, the applied technique induced a substantial increase in the volume of the vestibular peri-implant gingiva at 12-month follow-up (range, 24%-69%, mean 40.4%) with respect to day 0. The gingival mucosa appeared normal at both inspection and evaluation of the periodontal parameters (PD 2.7 ± 1 mm; BoP 0.11 ± 0.2 seconds; PI 0.19 ± 0). Patients\' satisfaction with perceived pain/discomfort and esthetic outcome was high. These findings indicate that laser-aided pouch roll flap is a safe, patient-liked procedure whose long-term effectiveness has been objectively demonstrated by volumetric and clinical assessment.
摘要：
种植学的最终目标是以无法与天然牙列的其余部分区分开的方式恢复整个牙齿-牙龈复合体。这项研究评估了前庭牙龈软组织的体积和临床变化，对于令人满意的雕刻和美学效果至关重要，在第二阶段手术中使用激光辅助袋卷装进行治疗，以揭示牙种植体。12名患者在16个无牙部位有轻度的脊缺陷，包括远端元件，登记并重新评估长达1年。数字印象，用口内激光扫描仪和软件拍摄，在治疗前（第0天）和治疗后（第12个月）进行分析。叠加数字STL文件以通过3D分析软件评估选定的感兴趣的植入物周围区域(ROI)中的体积和线性尺寸变化。临床牙周参数（探查深度PD，探查BoP时出血,还评估了菌斑指数PI）和患者报告的主观结局。在所有的病人中，在12个月的随访中，所应用的技术引起前庭种植体牙龈体积的大幅增加（范围24-69％，平均40,4%)，相对于第0天。在检查和评估牙周参数（PD2.7±1mm；BoP0.11±0.2s；PI0.19±0）时，牙龈粘膜均正常。患者对感知到的疼痛/不适和美学结果的喜好很高。这些发现表明，激光辅助袋翻盖是一种安全的，患者样手术，其长期有效性已通过容量和临床评估得到客观证明。
