研究目的:

通过对比评估经磨牙区即刻种植术、位点保存术与常规拔牙后延期种植修复三种术式对牙槽嵴骨组织及软组织变化差异,为磨牙区种植修复的术式选择提供高质量的临床证据。  

Objectives of Study:

By comparatively evaluating dimensional changes in alveolar bone and soft tissues following three distinct protocols—immediate implant placement in the molar region, socket preservation, and conventional delayed implant placement after extraction—this study aims to generate high-level clinical evidence to inform the selection of optimal implant rehabilitation approaches in the molar region.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1. 年龄18~70周岁(包含18及70周岁),性别不限; 2. 磨牙区不可保留的残根残冠,在牙槽骨骨内明显占位; 3. 种植位点无急性感染; 4. 拔牙窝根方可用牙槽骨高度大于4mm,可保证种植体初期稳定性; 5. 在获取充分知情后,自愿参加并签署《知情同意书》的患者,配合接收定期检查的患者。

Inclusion criteria

1. Age 18–70 years (inclusive of 18 and 70 years), no gender restriction; 2. Remaining roots or crowns in the molar area that cannot be preserved, significantly occupying the alveolar bone; 3. No acute infection at the implant site; 4. The extraction socket can only be used if the alveolar bone height is greater than 4mm to ensure initial stability of the implant; 5. Patients who voluntarily participate and sign the "Informed Consent Form" after receiving full information, and cooperate with regular follow-up examinations.

排除标准:

1.未控制的糖尿病,免疫系统疾病等全身系统性疾病; 2.一年内接受头颈部放疗; 3.一年内化疗史; 4.未控制的牙周病,余留天然牙不愿接受牙周治疗; 5.活动性的上颌窦感染或者长期上颌窦感染病史; 6.长期每天吸烟超过一包; 7.心理疾病如抑郁,焦虑无法配合治疗; 8.拒绝治疗后定期复查; 9.怀孕或哺乳期女性,或2年内有怀孕准备的女性。

Exclusion criteria:

1. Uncontrolled diabetes, immune system diseases, and other systemic diseases; 2. Received head and neck radiotherapy within the past year; 3. History of chemotherapy within the past year; 4. Uncontrolled periodontal disease, remaining natural teeth with refusal to undergo periodontal treatment; 5. Active maxillary sinus infection or a history of chronic maxillary sinus infection; 6. Long-term smoking of more than one pack per day; 7. Psychological disorders such as depression or anxiety that prevent cooperation with treatment; 8. Refusal of treatment followed by regular check-ups; 9. Pregnant or breastfeeding women, or women planning pregnancy within the next 2 years.
