纳入标准:

1.无任何可能损害种植体伤口愈合的系统性疾病; 2.研究招募仅限于年龄≥ 18岁且标准化健康问卷得分为 1 或 2 的受试者; 3.适当的牙周健康(仅纳入 PD < 5 mm;探诊出血评分和全口菌斑评分< 20%的患者,以降低手术后发生生物学并发症); 4.上颌前牙缺失,且存在邻近的天然牙; 5.与拔牙后植入参数相关的其他条件包括: a 存在超过 4 mm 的用于初期稳定性的根尖骨; b 颊侧骨板损失不超过 3mm,水平骨增量不大于3mm; c 不存在易导致大量骨丧失的慢性根尖周病变; d 存在 2mm 的角化龈; 6.自愿参与,并在相应的知情同意书上签字; 7.患者依从性好,能按要求复查。

Inclusion criteria

1. absence of any systemic disease that may impair implant wound healing; 2. recruitment to the study was limited to subjects aged ≥ 18 years with a standardized health questionnaire score of 1 or 2; 3. appropriate periodontal health (only patients with PD < 5 mm; probing bleeding score and whole mouth plaque score < 20% were included to minimize the occurrence of biological complications after the procedure); 4. missing maxillary anterior teeth and presence of adjacent natural teeth; 5. other conditions related to post-extraction implant parameters include. a Presence of more than 4 mm of apical bone for initial stabilization; b Loss of buccal bone plate not exceeding 3 mm and horizontal bone gain not greater than 3 mm; c The absence of chronic periapical lesions that predispose to significant bone loss; d Presence of 2 mm of keratinized gingiva; 6. Voluntary participation and signing of the appropriate informed consent form; 7. Good patient compliance and ability to review as required.

排除标准:

1.医学状况不佳的受试者(ASA III-V 级)(美国麻醉医师协会对患者进行的手术危险性分级); 2.植入治疗或辅助手术的一般禁忌症(如免疫缺陷、晚期系统性疾病、皮质类固醇药物治疗); 3.侵袭性、恶性骨肿瘤所致的骨缺损及可能影响骨转换或骨或非矿化组织代谢的治疗或疾病(如双膦酸盐或局部放射治疗); 4.不符合 GBR 手术或牙种植体植入术的患者; 5.同期重度吸烟者(每天吸烟 10 支以上); 6.本研究开始前 3 个月内曾参加其他临床试验; 7.严重心、肝、肾功能不全者(心功能≥II 级,谷丙酸氨基转移酶 AST 大于正常值上限的 2 倍,血清肌酐大于正常值上限);糖尿病患者控制不佳者(经药物控制空腹血糖仍≥8.0mmol/L); 8.精神异常,无行为自主能力;过敏性体质患者,孕妇或哺乳期及半年内有怀孕计划者; 9.不能按要求复诊失访的患者。

Exclusion criteria:

1. medically compromised subjects (ASA Class III-V) (American Society of Anesthesiologists surgical risk classification of patients); 2. general contraindications to implant therapy or adjuvant surgery (e.g., immunodeficiency, advanced systemic disease, corticosteroid medication); 3. Bone defects due to invasive, malignant bone tumors and treatments or diseases that may affect bone conversion or metabolism of bone or non-mineralized tissue (e.g., bisphosphonates or local radiation therapy); 4. Patients who are not eligible for GBR surgery or dental implant placement; 5. Heavy smokers (more than 10 cigarettes per day) during the same period; 6. Participation in other clinical trials within 3 months prior to the start of the study; 7. patients with severe cardiac, hepatic, or renal insufficiency (cardiac function ≥ Class II, glutamic acid aminotransferase AST greater than twice the upper limit of normal, serum creatinine greater than the upper limit of normal); patients with diabetes mellitus that is poorly controlled (fasting blood glucose ≥ 8.0 mmol/L even after medication control); 8. Mental anomalies, no behavioral autonomy; allergic patients, pregnant women or breastfeeding and those who plan to become pregnant within six months; 9. Patients who can not follow the requirements of follow-up lost visits.
