Abstract

PurposeTo evaluate the short‐term success and survival rates of immediately restored surface modified two‐piece zirconia implants (CL).Material and MethodsA total of 23 patients had received CL implants (n = 26) for single‐tooth replacements in the anterior and posterior maxilla and mandible at healed extraction sites. Immediate implant restoration was accomplished if an insertion torque ≥ 30 Ncm was reached (Type 3–4 A protocol). Final occlusally screw‐retained crowns were provided after 3 months of healing.Implant survival and success (i.e., bleeding on probing—BOP, probing pocket depth—PD, mucosal recession—MR) were assessed at 6 and 12 months following final restoration.Patient‐reported outcomes were evaluated at 6 and 12 months.ResultsFive implants (n = 5 patients) could not be immediately restored, and four implants were lost during follow‐up. The survival rates amounted to 80%. For the final analysis, 16 patients with a total of 16 implants were evaluated. Minor changes to baseline (final restoration) were noted at 6 and 12 months for mean BOP (−3.3% ± 13.14%; 8.3% ± 16.9%), PD (−0.15 ± 0.48 mm; 0.08 ± 0.48 mm), and MR (0.0 ± 0.0 mm; 0.0 ± 0.0 mm) values. Mechanical and technical complications were not observed. Patients expressed an overall high satisfaction at 6 and 12 months.ConclusionsThe presented immediate restoration protocol may be associated with an increased risk for early implant losses.

即刻修复、表面修饰两片式氧化锆种植体的临床表现。前瞻性案例系列

目的评价即刻修复的表面修饰二片式氧化锆种植体（CL）的近期成功率和成活率。材料和方法23例患者（n = 26）在上颌前、后牙和下颌骨愈合的拔牙部位接受CL种植体单牙置换。如果插入扭矩≥30 Ncm，则立即完成种植体修复（Type 3-4 A方案）。愈合3个月后提供闭合螺钉保留冠。在最终修复后的6个月和12个月评估种植体的生存和成功（即探针- bop，探针口袋深度- pd，粘膜萎缩- mr）。在6个月和12个月时评估患者报告的结果。结果5例患者种植体不能立即修复，4例患者在随访中丢失。成活率达80%。最后，我们对16例患者共16颗种植体进行了评估。在6个月和12个月时，平均BOP（- 3.3%±13.14%;8.3%±16.9%）、PD（- 0.15±0.48 mm; 0.08±0.48 mm）和MR（0.0±0.0 mm; 0.0±0.0 mm）值与基线（最终恢复）有轻微变化。没有观察到机械和技术并发症。患者在6个月和12个月时总体满意度较高。结论立即修复方案可能与早期种植体丢失的风险增加有关。

期刊介绍： Clinical Oral Implants Research conveys scientific progress in the field of implant dentistry and its related areas to clinicians, teachers and researchers concerned with the application of this information for the benefit of patients in need of oral implants. The journal addresses itself to clinicians, general practitioners, periodontists, oral and maxillofacial surgeons and prosthodontists, as well as to teachers, academicians and scholars involved in the education of professionals and in the scientific promotion of the field of implant dentistry.
