The purpose of this study was to evaluate the vertical bone loss after using different techniques: sloped implants or standard implants with guided bone regeneration. Patients with tooth gap and horizontal bone deficiency were randomly allocated to the test group (implants with sloped platform-SLP) and control group (standard design implants with guided bone regeneration-GBR). The primary outcome was bone loss (6 months after finishing the prosthetic treatment). Secondary outcomes included the following: patient-reported outcome measures (PROMs), post-operative edema, keratinized mucosa width, and pink aesthetic score (PES). The average bone loss at 6 months was 0.23 ± 0.15 mm and 1.03 ± 0.37 mm in the SLP and GBR groups, respectively. The SLP group was characterized by lower pain intensity the first 7 days ( < 0.001), lower post-operative edema ( < 0.001), lower consumption of NSAIDs on days 1, 3, 5, and 7 ( = 0.002, <0.001, <0.001, and 0.008), and lower total OHIP-14 ( = 0.047) on day 7. The keratinized mucosa width was 3.7 (3.4-4.0) mm and 2 (1.4-2.0) mm in the SLP and GBR groups, respectively. The preservation of the mesial, distal papillae, and the level of soft tissue correspondence were significantly higher in the SLP group ( = 0.003, 0.038, <0.001). In the SLP group, more natural color and better texture of soft tissues were found ( = 0.048, = 0.041). The use of implants with a sloped platform resulted in superior outcomes compared to the standard-design implants with GBR.
倾斜种植体或采用引导骨再生的标准种植体。有牙间隙和水平骨缺损的患者被随机分配到试验组（倾斜平台种植体-SLP）和对照组（采用引导骨再生的标准设计种植体-GBR）。主要结局是骨吸收（修复治疗完成6个月后）。次要结局包括以下方面：患者报告结局量表（PROMs）、术后水肿、角化黏膜宽度和粉色美学评分（PES）。SLP组和GBR组6个月时的平均骨吸收分别为0.23±0.15mm和1.03±0.37mm。SLP组的特点是前7天疼痛强度较低（<0.001）、术后水肿较轻（<0.001）、第1、3、5和7天非甾体抗炎药的消耗量较低（分别为=0.002、<0.001、<0.001和0.008）以及第7天OHIP-14总分较低（=0.047）。SLP组和GBR组的角化黏膜宽度分别为3.7（3.4-4.0）mm和2（1.4-2.0）mm。SLP组近中、远中乳头的保留情况以及软组织对应水平显著更高（=0.003、0.038、<0.001）。在SLP组中，发现软组织颜色更自然、质地更好（=0.048、=0.041）。与采用GBR的标准设计种植体相比，使用倾斜平台种植体产生了更好的效果。
