The goal of this study was to assess the peri-implant condition, peri-implant bone loss (PBL), and complication rates of short dental implant-supported splinted crowns (SDI-SCs) and non-splinted crowns (SDI-NSCs) in the maxillary premolar-molar region.
Patients who had short implants placed near their maxillary sinuses were evaluated. Both patient satisfaction and presence of any technical complication, e.g. porcelain wear and chipping, loss of retention and loosening of the abutment, fixture or screw, were noted. The peri-implant plaque index (PIPI), probing depth (PIPD), bleeding on probing (PIBP), and peri-implant bone loss (PBL) were evaluated. To assess the impact of prosthesis type and SDI placement on technical problems, a log-rank test was computed. p < 0.05 was considered statistically significant.
A total of 72 patients agreed to be followed-up, showing a mean follow-up time of 3.1 years. Ninty-five implants in total (55 SDI-SCs, and 40 SDI-NSCs) with moderately rough surfaces were evaluated. The average PBL score for implant and patients was 1.27 (0.02-3.97) and 1.25 (0.03-4.41), respectively. More technical complications were observed with single crowns than with splinted crowns. There were no statistically significant differences in the peri-implant parameters between SDI-SCs and SDI-NSCs (p > 0.05). PBL at molar sites was substantially higher than at premolar sites (p = 0.048). Sixty patients (83.3%) were satisfied with the appearance of the crowns, while 57 patients (79.1%) were satisfied with the crowns' performance.
The peri-implant conditions, bone levels, technical complication rates and patient satisfaction were comparable between the SDI-SCs and SDI-NSCs. However, implants placed in the molar sites had statistically significantly greater bone loss in comparison to those at the premolar sites.
本研究旨在评估上颌前磨牙-磨牙区短种植体支持的可摘夹板式冠（SDI-SC）和非夹板式冠（SDI-NSC）的种植体周围状况、种植体周围骨丧失（PBL）和并发症发生率。
评估了在靠近上颌窦的位置植入短种植体的患者。记录了患者满意度和任何技术并发症的存在，例如瓷质磨损和碎裂、固位丧失和基台、修复体或螺丝松动等。评估了种植体周围菌斑指数（PIPI）、探诊深度（PIPD）、探诊出血（PIBP）和种植体周围骨丧失（PBL）。为了评估修复体类型和 SDI 放置对技术问题的影响，计算了对数秩检验。p < 0.05 被认为具有统计学意义。
共有 72 名患者同意接受随访，平均随访时间为 3.1 年。共评估了 95 个种植体（55 个 SDI-SC 和 40 个 SDI-NSC），表面均为中度粗糙。种植体和患者的平均 PBL 评分分别为 1.27（0.02-3.97）和 1.25（0.03-4.41）。与夹板冠相比，单冠的技术并发症更多。SDI-SC 和 SDI-NSC 之间的种植体周围参数无统计学差异（p > 0.05）。磨牙部位的 PBL 明显高于前磨牙部位（p = 0.048）。60 名患者（83.3%）对冠的外观满意，57 名患者（79.1%）对冠的性能满意。
SDI-SC 和 SDI-NSC 之间的种植体周围状况、骨水平、技术并发症发生率和患者满意度相当。然而，与前磨牙部位相比，磨牙部位的种植体骨丧失有统计学显著差异。
